Seat Leon. Service Manual - part 17

Checking and refilling levels

●

Take care not to cause short circuits in the

electrical system, especially when working
on the battery.

●

If working inside the engine compartment,

remember that, even when the ignition is
switched off, the radiator fan may start up au-
tomatically, and therefore there is a risk of in-
jury.

●

Never cover the engine with additional in-

sulating materials such as a blanket. Risk of
fire!

●

Do not unscrew the cap on the coolant ex-

pansion tank when the engine is hot. The
cooling system is under pressure.

●

Protect face, hands and arms by covering

the cap with a large, thick rag to protect
against escaping coolant and steam.

●

If it is necessary to work in the engine com-

partment while the engine is running, the ro-
tating components (for example, poly-V belt,
alternator, radiator fan) and the high voltage
ignition system are an additional hazard.

●

Observe the following additional warnings

if work on the fuel system or the electrical
system is necessary:

–

Always disconnect the battery from the
on-board network.

–

Do not smoke.

–

Never work near naked flames.

–

Always keep an approved fire extinguish-
er immediately available.

CAUTION

When topping up fluids make sure the correct
fluid is put into the correct filler opening, oth-
erwise this can cause serious malfunctions or
engine damage.

For the sake of the environment

Inspect the ground underneath your vehicle
regularly so that any leaks are detected at an
early stage. If you find spots of oil or other
fluids in the area where it was parked, have
your vehicle inspected at the workshop.

Note

In right-hand drive vehicles* some brake flu-
id reservoirs are on the other side of the en-
gine compartment

not unfolded. Otherwise the paint may be
damaged.

The bonnet can only be unlocked when the
driver door is open.

WARNING

Never open the bonnet if you see steam or
drips of coolant being released from the en-
gine compartment. Failure to comply could
result in burns. Wait until no steam or coolant
can be seen before opening the bonnet.

WARNING

●

For safety reasons the bonnet must always

be completely closed when the vehicle is
moving. Therefore, after closing the bonnet,
always check that the locking element is
properly engaged. This is the case if the bon-
net is flush with the adjacent body panels.

●

Should you notice that the bonnet is not

safely secured when the vehicle is moving,
stop the vehicle immediately and close the
bonnet. Failure to follow this instruction
could result in an accident.

Engine oil

General notes

The engine comes with a special, multi-grade
oil that can be used all year round.

Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.

The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.

We recommend that the oil change indicated
in the Maintenance Programme, be per-
formed by a technical service or specialised
workshop.

The correct oil specifications for your engine
are listed in the 

››› 



page 51, Oil proper-

ties

.

Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).

If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6,

this means that your vehicle has the LongLife
service programmed. If it lists the codes QI1,
QI2, QI3, QI4 or QI7, the interval service is
dependent on time/distance travelled.

Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on the characteris-
tics and individual driving profiles, enable
the extension of the oil change service (Long-
Life service intervals).

Because this oil is essential for extending the
service intervals, it 

must only be used ob-

serving the following indications:

●

Avoid mixing it with oil for fixed service in-

tervals.

●

Only in exceptional circumstances, if the

engine oil level is too low 

››› 

page 265

 and

LongLife oil is not available, it is permitted to
top up (once) with oil for 

fixed service inter-

vals 

››› 



page 51

 (up to a maximum of 0.5

litres).

Fixed service intervals*
If your vehicle does not have the “LongLife
service interval” or it has been disabled (by
request), you may use oils for 

fixed service

intervals, which also appear in

››› 



page 51, Oil properties

. In this case,

your vehicle must be serviced after a fixed in-
terval of 1 year/15,000 km (10,000 miles)

(whatever comes first) 

››› 

Booklet  Mainte-

nance Programme

.

●

In exceptional circumstances, if the engine

oil level is too low 

››› 

page 265

 and you can-

not obtain the oil specified for your vehicle,
you can add a small quantity of oil conform-
ing to the specification ACEA A2 or ACEA A3
(petrol engines) or ACEA B3 or ACEA B4 (die-
sel engines) (up to 0.5 l).

Vehicles with diesel particulate filter*
The Maintenance Programme states whether
your vehicle is fitted with a diesel particulate
filter.

Only VW 507 00 engine oil, with reduced ash
formation, may be used in diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore:

●

Avoid mixing this oil with other engine oils.

●

Only in exceptional circumstances, if the

engine oil level is too low 

››› 

page 265

 and

you cannot obtain the oil specified for your
vehicle, you can use a small quantity of oil
(once) conforming to the VW 506 00,
VW 506 01, VW 505 00, VW 505 01 or
ACEA B3/ACEA B4 specification. (up to 0.5 l).

Checking and refilling levels

Checking engine oil level

Fig. 241 

Engine oil dipstick.

Read the additional information carefully

››› 



page 50

The engine oil dipstick indicates the level of
the oil.

Checking oil level

–

Park the vehicle in a horizontal position.

–

Briefly run the engine at idle speed until
the operating temperature is reached and
then stop.

–

Wait for about two minutes.

–

Pull out the dipstick. Wipe the dipstick with
a clean cloth and insert it again, pushing it
in as far as it will go.

–

Then pull it out once more and check the oil
level 

››› 

Fig. 241

. Top up with engine oil if

necessary.

Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 0.5 l/1000 km. Oil
consumption is likely to be higher for the first
5,000 km. For this reason the engine oil level
must be checked at regular intervals, prefera-
bly when filling the tank and before a jour-
ney.

WARNING

Any work carried out in the engine compart-
ment or on the engine must be carried out
cautiously.

●

When working in the engine compartment,

always observe the safety warnings

››› 

page 262

Advice

CAUTION

If the oil level is above the area 

A

 do not

start the engine. This could result in damage
to the engine and catalytic converter. Contact
a specialised workshop.

For the sake of the environment

The oil level must never be above area 

A

.

Otherwise oil can be drawn in through the
crankcase breather and escape into the at-
mosphere via the exhaust system.

Note

Before a long trip, we recommend finding an
engine oil that conforms to the correspond-
ing VW specifications and recommend keep-
ing it in the vehicle. This way, the correct en-
gine oil will always be available for a top-up if
needed.

Changing engine oil

Read the additional information carefully

››› 



page 50

.

The engine oil must be changed at the inter-
vals given in the service schedule.

We recommend that you have the engine oil
changed by a Technical Service.

The oil change intervals are shown in the
Maintenance Programme.

WARNING

Only change the engine oil yourself if you
have the specialist knowledge required!

●

Before opening the bonnet, read and ob-

serve the warnings 

››› 

page 262

.

●

Wait for the engine to cool down. Hot oil

may cause burn injuries.

●

Wear eye protection to avoid injuries, such

as acid burns, caused by splashes of oil.

●

When removing the oil drain plug with your

fingers, keep your arm horizontal to help pre-
vent oil from running down your arm.

●

Wash your skin thoroughly if it comes into

contact with engine oil.

●

Engine oil is poisonous! Used oil must be

stored in a safe place out of the reach of chil-
dren.

CAUTION

No additives should be used with engine oil.
This could result in engine damage. Any dam-
age caused by the use of such additives
would not be covered by the factory warranty.

For the sake of the environment

●

Because of disposal problems and the spe-

cial tools and specialist knowledge required,
we recommend that you have the engine oil
and filter changed by a Technical Service.

●

Never pour oil down drains or into the

ground.

●

Use a suitable container when draining the

used oil. It must be large enough to hold all
the engine oil.

Cooling system

Topping up coolant

Read the additional information carefully

››› 



page 51

Top up coolant when the level is below the
MIN (minimum) mark.

Checking coolant level

–

Park the vehicle in a horizontal position.

–

Switch the ignition off.

–

Read off the coolant level on coolant ex-
pansion tank. When the engine is cold, the
coolant level should be between the marks.
When the engine is hot, it may be slightly
above the upper mark.

Topping up coolant

–

Wait for the engine to cool down.

–

Cover the coolant expansion tank cap with
a cloth and carefully unscrew it to the left

››› 

.

–

Top up the coolant only if there is still cool-
ant in the expansion tank, otherwise you

266

Checking and refilling levels

could 

damage the engine. If there is no

coolant in the expansion tank, do not con-
tinue driving. You should obtain professio-
nal assistance 

››› 

.

–

If there is still some coolant in the expan-
sion tank, top up to the upper mark.

–

Top up with coolant until the level becomes
stable.

–

Screw the cap back on correctly.

Any loss of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no
leaks in the engine cooling system, a loss of
coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.

WARNING

●

The cooling system is under pressure. Do

not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!

●

The antifreeze and coolant fluid can be a

health hazard. Therefore, the antifreeze
should be stored in the original container in a
safe place out of reach of children. Failure to
comply could result in poisoning.

●

If working inside the engine compartment,

remember that, even when the ignition is
switched off, the radiator fan may start up au-

tomatically, and therefore there is a risk of in-
jury.

WARNING

If there is not enough anti-freeze in the cool-
ant system, the engine may fail leading to se-
rious damage.

●

Please make sure that the percentage of

additive is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.

●

When the outside temperature is very low,

the coolant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold.

CAUTION

Do not top up the expansion tank with cool-
ant fluid if it is empty! Air could enter the
cooling system. In this case, stop driving.
Seek specialist assistance. Otherwise, there
is a risk of engine damage.

CAUTION

The original additives should never be mixed
with coolants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system.

●

If the fluid in the expansion tank is not pur-

ple but is, for example, brown, this indicates

that the G13 additive has been mixed with an
inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage.

For the sake of the environment

Coolants and additives can contaminate the
environment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment.

Brake fluid

Checking the brake fluid level
The brake fluid level must be between the
MIN and MAX markings.

However, if the brake fluid level goes down
noticeably in a short time, or drops below the
MIN mark, there may be a leak in the brake
system. Seek specialist assistance. A warn-
ing light on the instrument panel display
monitors the brake fluid level

Advice

In right-hand drive vehicles the brake fluid
reservoir is on the other side of the engine
compartment.

Changing brake fluid
The regular intervals at which the brake fluid
should be replaced are listed in the Mainte-
nance Programme. We recommend you have
it replaced at a SEAT Official Service, during
an Inspection Service.

WARNING

●

Brake fluid should be stored in the closed

original container in a safe place out of reach
of children. Risk of poisoning!

●

If the brake fluid is left in the system for

too long and the brakes are subjected to
heavy use, vapour bubbles may form in the
brake system. This would seriously affect the
efficiency of the brakes and the safety of the
vehicle. This may cause an accident.

CAUTION

Brake fluid should not come into contact with
the vehicle paintwork, as it is abrasive.

.

●

The windscreen washer reservoir is marked

with the symbol  on the cap.

●

Check there is enough windscreen water in

the reservoir.

Recommended windscreen wipers

●

For the hottest seasons we recommend

summer G 052 184 A1 for clear glass. Propor-
tions of the mixture in the washer fluid tank:
1:100 (1 part concentrate per 100 parts wa-
ter).

●

All year round, G 052 164 A2 for clear

glass. Approximate proportion of the winter
mixture, up to -18°C (0°F): 1:2 (1 part con-
centrate per 2 parts water); otherwise, a 1:4

proportion of mixture in the washer fluid
tank.

Capacity
The reservoir holds approximately 3 litres in
versions without headlight washer and 5 li-
tres in versions with headlight washer.

WARNING

If the water from the windscreen washer does
not contain enough anti-freeze, it may freeze
on the windscreen and rear window, reducing
forward and rear visibility.

●

In winter, ensure the windscreen washer

contains enough anti-freeze.

●

In cold conditions, you should not use the

windscreen wiper system unless you have
warmed the windscreen with the ventilation
system. The antifreeze could freeze on the
windscreen and reduce visibility.

WARNING

Never mix an unsuitable antifreeze or other
similar additives with the windscreen washer
water. A greasy layer may be formed on the
windscreen which will impair visibility.

●

Use clean water with a window cleaner rec-

ommended by SEAT.

●

If necessary, add a suitable antifreeze to

the water in the reservoir.

268

Checking and refilling levels

CAUTION

●

Do not mix cleaning products recommen-

ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.

●

When topping up service fluids, make abso-

lutely certain that you fill the fluids into the
correct reservoirs. Using the wrong fluids
could cause serious malfunctions and engine
damage!

●

Not having windscreen wiper fluid reduces

visibility through the windscreen, and leads
to loss of visibility in headlights in models
with headlight washer.

place battery! Failure to do so may lead to an
explosion.

Note

Use only the terminals in the engine compart-
ment to charge the battery.

Replacing the battery

The new battery should have the same speci-
fications (amperage, load and voltage) as the
used battery.

Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy 

››› 

page 255

.

The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop.

Wheels

CAUTION

●

Some vehicles, for example those with the

Start-Stop system* are fitted with a special
battery (AGM-type or EFB-type battery). If any
other type of battery is fitted, the Start-Stop
function may be considerably reduced and
the vehicle may not stop on repeated occa-
sions.

●

Make sure that the vent hose is always at-

tached to the original opening on the side of
the battery. Gases or battery acid can other-
wise escape and possibly cause damage.

Wheels and tyres

General notes

–

When driving with 

new tyres, be especially

careful during the first 500 km (300 miles).

–

If you have to drive over a kerb or similar
obstacle, drive very slowly and as near as
possible at a right angle to the obstacle.

–

Check from time to time if the tyres are
damaged (punctures, cuts, cracks or
dents). Remove any foreign objects embed-
ded in the treads.

–

Damaged wheels and tyres must be re-
placed immediately.

–

Keep grease, oil and fuel off the tyres.

–

Replace any missing valve caps as soon as
possible.

–

Mark the wheels before taking them off so
that they rotate in the same direction when
put back.

–

When removed, the wheels or tyres should
be stored in a cool, dry and preferably dark
place.

New tyres
New tyres do not give maximum 

grip straight

away and should therefore be “run in” by

driving carefully and at moderate speeds for
about the first 500 km (300 miles). This will
also increase the useful life of the tyres.

The 

tread depth of new tyres may vary, ac-

cording to the type and make of tyre and the
tread pattern.

Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual 

vibration or the

car 

pulling to one side, this may indicate that

one of the tyres is damaged. Reduce speed
immediately if there is any reason to suspect
that damage may have occurred. Inspect the
tyres for damage. If no external damage is
visible, drive slowly and carefully to the near-
est specialised workshop and have the car
inspected.

Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on single drive tyres. Al-
ways note the direction of rotation indicated
when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplan-
ing, excessive noise and wear.

Retrofitting accessories
If you wish to change or fit wheels, rims or
wheel trims, we recommend that you consult
with a SEAT Official Service centre for advice
regarding current techniques.

Tyre useful life

Fig. 243 

Location of the tyre pressure sticker.

Correct inflation pressures and sensible driv-
ing habits will increase the useful life of your
tyres.

–

Check tyre pressure at least once a month,
and also prior to any long trip.

–

The tyre pressure should only be checked
when the tyres are cold. Do not reduce the
pressure of warm tyres.

–

Adjust tyre pressure to the load being car-
ried by the vehicle.

–

In vehicles with a tyre pressure indicator,
save the modified pressure of tyres

››› 

page 275

.

–

Avoid fast cornering and hard acceleration.

–

Inspect the tyres for irregular wear from
time to time.

The useful life of your tyres depends on the
following factors:

Tyre pressure
Tyre pressure values are indicated on the
sticker on the inside of the fuel tank flap

››› 

Fig. 243

.

Insufficient or excessive pressure greatly re-
duces the useful life of the tyres and adverse-
ly affects vehicle performance and ride. Cor-
rect inflation pressures are very important,
especially at 

high speeds.

Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (tyre pressure ). When driving
with comfort tyre pressure fuel consumption
may increase slightly.

The tyre pressure must be adjusted according
to the load the vehicle is carrying. If the vehi-
cle is going to carry the maximum load, the
tyre pressure should be increased to maxi-
mum value indicated on the sticker on the in-
side of the fuel tank flap.

Do not forget the spare wheel when checking
the tyre pressures: Keep this spare wheel in-
flated to the highest pressure required for the
road wheels.

In the case of a minimised temporary spare
wheel (125/70 R16 or 125/70 R18) inflate to
a pressure of 4.2 bar as indicated on the tyre
pressure label on the fuel tank flap.

Driving style
Fast cornering, heavy acceleration and hard
braking (squealing tyres) all increase tyre
wear.

Wheel balance
The wheels on new vehicles are balanced.
However, certain circumstances may lead to
imbalance (run-out), which is detected as vi-
brations in the steering wheel.

Unbalanced wheels should be rebalanced, as
they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted
or if a tyre is repaired.

Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If you notice excessive tyre wear, you
should check wheel alignment at a SEAT Offi-
cial Service.

272

Wheels

WARNING

●

Always adapt the tyre pressure accordingly

when the vehicle load changes.

●

A tyre with low air pressure has to flex a lot

more when the vehicle is heavily loaded or at
high speeds, therefore causing overheating
to occur. Under these conditions, the tyre
bead may be released or the tyre may burst.
Risk of accident!

For the sake of the environment

Under-inflated tyres will increase fuel con-
sumption.

Wear indicators

Fig. 244 

Tyre tread: tread wear indicators

Tread wear indicators indicate if a tyre is
worn.

The original tyres on your vehicle have
1.6 mm high “tread wear indicators” running
across the tread. Depending on the manufac-
turer, there will be 6 to 8 of them spaced at
equal distances around the tyre. Markings on
the tyre sidewall (for instance the letters
“TWI” or a triangle) indicate the positions of
the tread wear indicators.

The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next
to the tread wear indicators). (Different fig-
ures may apply in other countries.)

WARNING

The tyres must be replaced at the latest when
the tread is worn down to the tread wear indi-
cators. Failure to follow this instruction could
result in an accident.

●

Especially in difficult driving conditions

such as wet or icy roads. It is important that
the tyre tread be as deep as possible and be
approximately the same on the tyres of both
the front and the rear axles.

●

The scant driving safety due to insufficient

tread depth is particularly evident in vehicle
handling, when there is a risk of “aquaplan-
ing” in deep puddles of water and when driv-
ing through corners, and braking is also ad-
versely affected.

●

The speed has to be adapted accordingly,

otherwise there is a risk of losing control over
the vehicle.

Changing wheels

Fig. 245 

Interchanging tyres.

To ensure that the wear is equal on all tyres
the wheels should be changed round from
time to time according to the system

››› 

Fig. 245

. The useful life of all the tyres will

then be about the same time.

New tyres or new wheels

–

All four wheels must be fitted with tyres of
the same type, size (rolling circumference)
and preferably the same tread pattern.

–

Tyres should be replaced at least in pairs
and not individually (i.e. both front tyres or
both rear tyres together).

–

Do not use tyres whose effective size ex-
ceeds the dimensions of the factory-ap-
proved makes of tyre.

Advice

–

If you wish to fit the vehicle with rims or
tyres different to those installed in manu-
facture, it is advisable to consult a SEAT Of-
ficial Service 

before purchasing them.

The tyres and wheel rims are an essential
part of the vehicle's design. The tyres and
rims approved by SEAT are specially matched
to the characteristics of the vehicle and make
a major contribution to good roadholding
and safe handling 

››› 

.

The sizes of the rims and tyres approved for
your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity or
COC document

1)

). The vehicle documentation

varies depending on the country of resi-
dence.

A knowledge of tyre designations makes it
easier to choose the correct tyres. The follow-
ing wording can be read on the sides of the
tyre:

205/55 R16 91V

This contains the following information:

205

Tyre width in mm

55

Height/width ratio in %

R

Tyre construction: 

Radial

16

Rim diameter in inches

91

Load rating code

V

Speed index

The 

manufacturing date is also indicated on

the tyre sidewall (possibly only on the inner
part):

DOT ... 2212 ...

it means, for example, that the tyre was man-
ufactured in the 22nd week of 2012.

But note that with some types of tyre, the ac-
tual tyre size can differ from the nominal size
marked on the tyre (for instance 205/55 R 16
91 W), and there may be significant differen-
ces in the contours of the tyres, even though
the tyres are marked with the same nominal
size designation. When replacing the tyres,
it is therefore important to make sure that
the actual size of the new tyres does not ex-
ceed the dimensions of the factory-approved
makes of tyre.

Failure to observe this requirement can af-
fect the clearance needed for the tyres. If the
tyres rub against the bodywork, in certain
circumstances the tyres, running gear or
bodywork and pipes may be damaged, and
vehicle safety could be severely impaired

››› 

.

If you use tyres that are approved by SEAT
you can be sure that the actual tyre dimen-

sions will be correct for your vehicle. If you
decide to fit a different type of tyre, you must
obtain the appropriate manufacturer's certif-
icate from the tyre retailer to confirm that
the tyres are suitable for your vehicle. Keep
this certificate in a safe place.

Your SEAT Official Service will be able to ad-
vise you on which tyres may be fitted to your
vehicle.

It is best to have all servicing of wheels and
tyres performed by a 

specialised workshop.

They are familiar with the procedure and
have the necessary special tools and spare
parts as well as the proper facilities for dis-
posing of the old tyres respecting the envi-
ronment.

WARNING

●

It is very important to ensure that the tyres

you have chosen have adequate clearance.
When selecting replacement tyres, do not re-
ly entirely on the nominal tyre size marked on
the tyre, since the effective tyre size can dif-
fer significantly depending on the manufac-
turer. Inadequate tyre clearance can result in
damage to the tyres or the vehicle, causing a
serious safety risk. Risk of accident! It may
also invalidate the vehicle's registration for
use on public roads.

1)

COC = certificate of conformity.

274

Wheels

●

Avoid running the vehicle on tyres that are

more than 6 years old. If you have no
alternative, you should drive slowly and with
extra care at all times.

●

If wheel trims are fitted after the car is pur-

chased, ensure that there is an adequate flow
of air for cooling the brake system.

For the sake of the environment

Old tyres must be disposed of according to
the laws in the country concerned.

Note

●

A SEAT Service Centre should be consulted

to find out whether wheels or tyres of differ-
ent sizes to those originally fitted by SEAT
can be fitted, and to find out about the com-
binations allowed between the front axle
(axle 1) and the rear axle (axle 2).

●

Never mount used tyres if you are not sure

of their “previous history”.

●

For technical reasons, it is not generally

possible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel.

Wheel bolts

The 

wheel bolts are matched to the rims.

When installing different wheels (for instance
alloy wheels or wheels with winter tyres) it is
important to use the correct wheel bolts with

the right length and correctly shaped bolt
heads. This ensures that wheels are fitted se-
curely and that the brake system functions
correctly.

The wheel bolts must be clean and turn easi-
ly.

A special adapter is required to turn the anti-
theft wheel bolts*

Tyre monitoring systems

Introduction

WARNING

Unsuitable handling of the wheels and tyres
may lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.

●

Check tyre pressures regularly and ensure

they are maintained at the pressures indica-
ted. Tyre pressure that is too low could cause
overheating, resulting in tread detachment or
even burst tyres.

●

Tyre pressure should be that indicated on

the label when the tyres are cold at all times

››› 

page 283

.

●

Regularly check the cold inflation pressure

of the tyres. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold.

●

Regularly check your tyres for damage and

wear.

●

Never exceed the maximum permitted

speed or loads specified for the type of tyre
fitted on your vehicle.

For the sake of the environment

Under-inflated tyres lead to increased fuel
consumption and tyre wear.

Note

●

Driving for the first time with new tyres at a

high speed can cause them to slightly ex-
pand, which could then produce an air pres-
sure warning.

●

Only replace used tyres with those author-

ised by SEAT for the corresponding type vehi-
cle.

●

Do not only rely on the tyre monitoring sys-

tem. Regularly check your tyres to ensure
that the tyre pressure is correct and that the
tyres are not damaged due to puncture, cuts,
tears and impacts/dents. Remove objects
from the tyres only when they have not
pierced the tyres.

tyre has structural damage.

Additionally, an audible warning can be heard and a text
message can be seen on the instrument panel display.


Stop! Reduce speed immediately! Stop the vehicle

safely as soon as possible. Avoid sudden manoeuvres
and braking! Check all tyres and pressures. Replace any
damaged tyres.

If flashing



System malfunction

The control lamp flashes for approximately one minute
and then lights up permanently.
If tyre pressure is correct, switch the ignition off and on
again. If the control lamp remains lit up, the tyre moni-
toring indicator can be calibrated. Have the system
checked by a specialised workshop.

Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on while the function is verified. They will
switch off after a few seconds.

WARNING

When the tyres are inflated at different pres-
sures or at a pressure that is too low then a
tyre may be damaged resulting in a loss of

control of the vehicle and a serious or fatal
accident.

●

If the warning lamp  lights up, stop im-

mediately and check the tyres.

●

If the tyres are inflated at different pres-

sures or if a tyre pressure is too low, this will
increase tyre wear, negatively affecting vehi-
cle stability and increasing braking distan-
ces.

●

If tyres are inflated at different pressures or

a tyre pressure is too low, a tyre may be dam-
aged and burst resulting in a loss of control
of the vehicle.

●

The driver is responsible for ensuring that

all of the vehicle tyres are correctly inflated
to the right pressure. The recommended tyre
pressure is indicated on the label

››› 

page 283

.

●

The tyre monitoring system can only oper-

ate correctly if all of the tyres are inflated to
the correct pressure when cold.

●

Driving with tyres at the wrong pressure

can damage them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.

●

Before starting a journey, always inflate

tyres to the correct pressure.

●

Tyres with insufficient pressure are subjec-

ted to more flexing. Due to this, the tyre
could become excessively hot, causing tread
separation and also tyre blow-out.

●

With an overloaded vehicle at high speed,

the tyres can overheat and burst resulting in
a loss of vehicle control.

●

Tyre pressures which are too high or too

low reduce the useful life of the tyre, affect-
ing vehicle performance.

●

If a tyre has not been punctured and it does

not have to be changed immediately, drive to
the nearest specialised workshop at a moder-
ate speed and have the tyre checked and in-
flated to the correct pressure.

WARNING

Observe the safety warnings 

››› 

 in Warning

and control lamps on page 109

.

Note

●

If excessively low tyre pressure is detected

with the ignition on, an audible warning will
sound. In the event that there is a fault in the
system, an audible warning will sound.

●

Driving on dirt tracks for a long period of

time or driving in a sporty style can tempora-
rily deactivate the TPMS. The control lamp
shows a fault, but disappears when road con-
ditions or the driving style change.
