User terms and conditions and

data sharing

The first time certain services and apps are
started, a pop-up window with the headings

Terms and conditions

 and 

Data sharing

may be shown.

The purpose is to inform about Volvo's user
terms and conditions and policy for data shar-
ing. By accepting data sharing, the user
accepts that certain information is sent from
the car. This is required so that certain servi-
ces and apps can have full functionality.

The data sharing function for online services
and apps is deactivated as default

. Data

sharing needs to be activated so that certain
online services and apps in the car can be
used. Data sharing can be set from the centre
display's settings menu or in connection with
the services or apps being started in the cen-
tre display.

Privacy and data sharing

With the software update made available
November 2017, privacy and data sharing set-
tings were introduced for online services and
downloaded apps. The settings can be found
under

app

You can use the Volvo On Call app to plan
and schedule the charging of your car.

You can schedule charging for the charging
stations you have saved in your app, which
may be practical if, for example, you need to
plan charging points along a travel itinerary or
when you are planning charging intervals for
your car at home or in your neighbourhood.

1. Via the 

Home

 tab, select 

Fuel range

 or

locations

. If you have not saved a

charging station yet or want to add
new locations, e.g. charging stations
along a travel itinerary or in your neigh-
bourhood, you can select the option for

Add location

 (you can save up to eight

charging stations).

2. Select the location for which you want to

schedule charging.
> A view opens for the saved location.

3. Select a start time for the charging.

4. Select an end time for the charging.

> A charging icon appears by the saved

location for which you have scheduled
the charging. When the icon disappears
again the scheduling has been saved
and programmed.

WHEELS AND TYRES

554

Tyres

The function of the tyres is to carry load, pro-
vide grip on the road surface, dampen vibra-
tion and protect the wheel from wear.

The tyres greatly affect the car's driving cha-
racteristics. The type of tyre, dimensions, tyre
pressure and speed rating are important for
how the car performs.

The car is fitted with tyres according to the
tyre information sticker found on the driver's
side door pillar (between the front door and
the rear door).

WARNING

A damaged tyre may lead to loss of control

over the car.

Recommended tyres

On delivery, the car is equipped with Volvo
original tyres that have the VOL

1

 marking on

the side of the tyres. These tyres are carefully
adapted to the car. In the event of changing
tyres, it is therefore important that the new
tyres also have this marking in order for the
car's driving characteristics, comfort and fuel
consumption to be maintained.

New tyres

Tyres are perishable. After a few years they
begin to harden at the same time as the fric-
tion capacity/characteristics gradually deterio-
rate. For this reason, aim to get as fresh tyres
as possible when you replace them. This is
especially important with regard to winter
tyres. The last four digits in the sequence
mean the week and year of manufacture. This
is the tyre's DOT marking (Department of
Transportation), and this is stated with four
digits, for example 0717. The tyre is then man-
ufactured in week 07, year 2017.

Tyre age

All tyres older than 6 years old should be
checked by an expert even if they seem
undamaged. Tyres age and decompose, even
if they are hardly ever or never used. The func-

tion can therefore be affected. This applies to
all tyres that are stored for future use. Exam-
ples of external signs which indicate that the
tyre is unsuitable for use are cracks or disco-
louration.

Tyre economy

•

Maintain the correct tyre pressure.

•

Avoid fast starts, heavy braking and
squealing tyres.

•

Tyre wear increases with speed.

•

Correct wheel alignment is very important.

•

Unbalanced wheels worsen tyre economy
and travelling comfort.

•

The tyres must have the same direction of
rotation during their entire service life.

•

When you change tyres, the tyres with the
best tread must be fitted on the rear
wheels to reduce the risk of oversteer dur-
ing heavy braking.

•

If you drive over kerbstones or deep holes
you can damage the tyres and/or wheel
rims permanently.

Tyre rotation

The car has no mandatory tyre rotation. Driv-
ing style, tyre pressure, climate and road con-
dition affect how quickly the tyres age and

1

There may be deviations for certain tyre dimensions.

WHEELS AND TYRES

* Option/accessory.

555

wear. Correct tyre pressure results in more
even wear.

To avoid differences in tread depth and to pre-
vent wear patterns forming on the tyres, the
front and rear wheels should be switched with
each other. A suitable distance for the first
change is approx. 5000 km (approx.
3100 miles) and then at 10000 km (approx.
6200 miles) intervals.

Volvo recommends the an authorised Volvo
workshop is contacted for checking if you are
uncertain about tread depth. If significant dif-
ferences in wear (> 1 mm difference in tread
depth) between tyres have already occurred,
then the least worn tyres must always be fit-
ted on the rear. Understeer is normally easier
to correct than oversteer, and leads to the car
continuing forwards in a straight line rather
than having the rear end skidding to one side,
resulting in possible complete loss of control
over the car. This is why it is important for the
rear wheels never to lose grip before the front
wheels.

Storing wheels and tyres

When you store complete wheels (tyres fitted
on wheel rims) they should be hung up or
positioned lying on their sides on the floor.

Tyres not fitted on rims must be stored lying
on their sides or standing upright, but not
hung up.

IMPORTANT

Tyres should be stored in a cool, dry and
dark place, and should never be stored
close to solvents, petrol, oils, etc.

WARNING

•

Wheel rim size and tyre size for your
Volvo are specified to meet stringent
requirements for stability and driving
characteristics. Unapproved combina-
tions of wheel rim size and tyre size
may have a negative effect on the car's
stability and driving characteristics.

•

Any damage caused by the fitting of
unapproved combinations of wheel rim
size and tyre size is not covered by the
new car warranty. Volvo accepts no lia-
bility for death, personal injury or any
costs caused by such installations.

Dimension designation for tyre

Designations for tyre dimension, load index
and speed rating.

The car has an approval for the complete vehi-
cle with certain combinations of wheel rims
and tyres.

Designation of dimensions

All tyres have a dimension designation, such
as: 245/45 R18 100 W.

245 Tyre width (mm)

45

Ratio between tyre wall height and
tyre width (%)

R

Radial ply

18

Rim diameter in inches

100 Codes for the maximum permitted

tyre load, tyre load index (LI)

W

Speed rating for maximum permitted
speed, speed rating (SS). (In this
case 270 km/h (168 mph).)

Load index

Each tyre has a certain capacity to carry a
load, a load index (LI). The car's weight deter-
mines the load capacity required of the tyres.

Speed rating

Each tyre can withstand a certain maximum
speed. Tyre speed rating, SS (Speed Symbol),
must at least correspond with the car's top
speed. The table below shows the maximum
permitted speed for each speed rating (SS).
The only exception to these regulations is win-
ter tyres

2

, where a lower speed rating may be

used. If such a tyre is selected, the car must
not be driven more quickly than the tyre is
rated for. For example, cars with Q rating tyres
must be driven at speeds not exceeding
160 km/h (100 mph). The road conditions and
applicable road traffic rules determine how
quickly the car can be driven, not the speed
rating of the tyres.

NOTE

The maximum permitted speed is specified
in the table.

Q

160 km/h (100 mph) (used only on
winter tyres)

T

190 km/h (118 mph)

H

210 km/h (130 mph)

V

240 km/h (149 mph)

W 270 km/h (168 mph)

Y

300 km/h (186 mph)

WARNING

The lowest permitted tyre load index (LI)

and speed rating (SS) for the tyres for each

respective engine variant are shown in the

specifications, which can be found in the

printed owner's manual. If a tyre with too

low a load index or speed rating is used, it

may overheat and be damaged.

Tyres' rotation direction

Tyres with a tread pattern which are designed
to only turn in one direction have the direc-
tion of rotation marked with an arrow.

The arrow shows the tyre's direction of rotation.

•

The tyre must always rotate in the same
direction throughout its lifespan.

•

Tyres should only be switched between
front and rear positions, never between
left and right-hand sides, or vice versa.

•

If the tyres are fitted incorrectly, the car's
braking characteristics and capacity to
force rain and slush out of the way are
adversely affected.

•

Tyres with the greatest tread depth should
always be fitted to the rear of the car (to
decrease the risk of skidding).

NOTE

Make sure that both pairs of wheels have
the same type and dimension, and also the
same make.

A tread wear indicator is a narrow elevation
across the longitudinal grooves of the tyre's
tread pattern. On the side of the tyre are the
letters TWI (Tread Wear Indicator). When the
tyre's tread depth is down to 1.6 mm (1/16
inch), the tread will be level in height with the
tread wear indicators. Change to new tyres as
soon as possible. Remember that tyres with
little tread depth provide very poor grip in rain
and snow.

Checking tyre pressure

Correct tyre pressure helps to improve driv-
ing stability, save fuel and extend the service
life of the tyres.

Tyre pressure decreases over time, this is a
natural phenomenon. Tyre pressure also varies
depending on ambient temperature. Driving
on tyres with tyre pressure that is too low
could result in the tyres overheating and being
damaged. Tyre pressure affects travelling
comfort, road noise and driving characteris-
tics.

Check the tyre pressures monthly. Use the
recommended tyre pressure for cold tyres in
order to maintain good tyre performance. Tyre
pressure that is too low or too high may cause
uneven wear on the tyres.

WARNING

•

Tyre pressure that is too low is the
most common cause of tyre failure and
may result in serious cracks in the tyre,
the tread loosening or the tyre explod-
ing, with unexpected loss of control of
the car and increased risk of personal
injury.

•

Tyres with pressure that is too low
reduce the load capacity of the car.

Cold tyres

The tyre pressure must be checked when the
tyres are cold. Tyres are considered cold when
they have the same temperature as the sur-
rounding air. This temperature is normally
reached when the car has been parked for at
least three hours.

After having driven approximately 1.6 km
(1 mile) these tyres are considered as warm. If
you have to drive further than this to inflate the
tyres, first check and record the tyre pressure
and inflate to a suitable tyre pressure when
you arrive at the pump.

When the outside temperature changes, the
tyre pressure also changes. A decrease in tem-
perature of 10 degrees causes the tyre pres-
sure to decrease 1 psi (7 kPa). Check the tyre
pressure regularly and adjust to the correct
pressure, which is specified on the car's tyre
information decal or certification label.

If you check the tyre pressure when the tyres
are warm then you must never release any air.
The tyres are warm due to driving and it is nor-
mal for the pressure to increase above the rec-
ommended pressure for cold tyres. A warm
tyre with tyre pressure equal to or below the
recommendation for cold tyres may have a
pressure that is far too low.

Adjusting tyre pressure

Tyre pressure decreases over time, this is a
natural phenomenon. The tyre pressure must
therefore sometimes be adjusted in order to
maintain the recommended tyre pressure.

Use the recommended tyre pressure for cold
tyres in order to maintain good tyre perform-
ance and even tread wear.

NOTE

To avoid incorrect tyre pressure, the pres-
sure should be checked on cold tyres.
"Cold tyres" means the tyres are the same
temperature as the ambient temperature
(approx. 3 hours after the car has been
driven). After a few kilometres of driving,
the tyres warm up and the pressure increa-
ses.

1. Remove the cap from the valve on one

tyre and then press the tyre pressure
gauge firmly down onto the valve.

2. Inflate the tyres to the correct pressure,

see the decal on the door pillar on the driv-
er's side showing the recommended pres-
sure for factory fitted tyres.

3. Refit the dust cap.

NOTE

•

After a tyre has been inflated, always
refit the dust cap in order to avoid dam-
age to the valve from gravel, dirt, etc.

•

Only use plastic dust caps. Metal dust
caps can rust and become difficult to
unscrew.

4. Check the tyres visually for any implanted

nails or other objects that could puncture
the tyre and cause leakage.

5. Check the sidewalls for any cavities, cuts,

bumps or other irregularities.

6. Repeat this for all tyres, including the

spare tyre

*

.

NOTE

If you have over-inflated, release air by
pressing in the metal pin in the centre of
the valve. Then check the pressure again
using the tyre pressure gauge.

Some spare tyres require a higher tyre
pressure than other tyres. Check in the tyre
pressure table or on the tyre pressure label.

shows which pressures the tyres should have
at different loads and speed conditions.

Improved fuel economy with ECO pressure

For a light load (max. 3 people) and a speed of
up to 160 km/h (100 mph), the ECO pres-
sures can be chosen for good fuel economy.
However, the lower comfort pressures are rec-
ommended instead if improved noise and trav-
elling comfort are desired.

Tyre pressure monitoring system

The tyre pressure monitoring system

, gives a

warning with an indicator symbol in the driver
display when the pressure in one or more of
the car's tyres is too low.

The symbol illuminates to indicate
low tyre pressure.

If there is a fault in the system the
tyre pressure warning symbol

flashes for approximately one minute and then
remains illuminated.

System description

The tyre pressure monitoring system meas-
ures differences in rotation speed between the
different wheels via the ABS system in order
to be able to determine whether they have the
correct tyre pressure. If the tyre pressure is too
low, the tyre's diameter is changed and, as a
result, so is its rotation speed. By comparing
the tyres with each other the system can
determine whether one or more tyres have
pressure that is too low.

General information on the tyre monitoring
system

In the information below, the tyre monitoring
system is referred to generically as TPMS.

Each tyre, including the spare tyre

*

, should be

checked once a month. When checking, the
tyre should be cold and have the air pressure
recommended by the car manufacturer speci-
fied on the tyre pressure label or in the tyre
pressure table. If the car has tyres of a differ-
ent size than that recommended by the manu-
facturer, find out what the correct air pressure
level is for these.

As an extra safety feature, the car is equipped
with a tyre pressure monitoring system
(TPMS), which shows when the air pressure in
one or more tyres is too low. When the indica-
tor symbol for low air pressure is lit, stop and
check the tyres as soon as possible and inflate
to the correct air pressure.

Driving with tyres that have tyre pressure that
is too low may cause the tyre to overheat,
which can cause a tyre failure. Low tyre pres-
sure also reduces fuel efficiency as well as tyre
service life, and can affect car handling and
stopping ability. Note that TPMS does not
replace regular tyre maintenance. It is the driv-
er's responsibility to maintain correct tyre
pressure, even if the limit for low tyre pressure

has not been reached so that the indicator
symbol illuminates.

The car is also equipped with a TPMS system
fault indicator, which indicates when the sys-
tem is not functioning correctly. The TPMS
system fault indicator is combined with the
indicator symbol for low tyre pressure. When
the system detects a fault, the symbol in the
driver display will flash for about one minute
and then remain illuminated. This procedure
will be repeated when the car is started until
the fault has been rectified. When the symbol
is illuminated, the system's ability to detect or
warn of low tyre pressure may be affected.

A TPMS system fault can occur for several
reasons, such as after changing to a spare
tyre, or changing tyres or wheels that prevent
TPMS from functioning correctly.

Always check the indicator symbol for TPMS
after changing one or more tyres in order to
ensure the new tyre or wheel is working cor-
rectly with TPMS.

Messages on the instrument panel

When the tyre pressure is too low, the indica-
tor symbol for low tyre pressure is illuminated
in the driver display and a message is shown.

To bear in mind

•

Always save a new tyre pressure in the
system after changing a wheel or adjust-
ing tyre pressure.

•

If you change to tyres of a different size to
the ones fitted at the factory, the system
must be reset by storing a new tyre pres-
sure for these tyres to avoid false warn-
ings.

•

If a spare wheel

*

 is used, it is possible that

the tyre pressure monitoring system does
not work correctly due to the differences
between the wheels.

•

The system does not replace the need for
regular tyre inspection and maintenance.

•

It is not possible to switch off the tyre
pressure monitoring system.
