Energy economy mode

System which manages the period of use of certain functions to conserve a sufficient level of
charge in the battery.
After the engine has stopped, you can still use functions such as the audio equipment, windscreen
wipers, dipped beam headlamps, courtesy lamps, etc. for a maximum combined period of thirty
minutes.

This period may be greatly reduced if
the battery is not fully charged.

A flat battery prevents the engine from
starting.
For more information on the 12 V
battery

, refer to the corresponding

section.

If the telephone is being used at the
same time with the touch screen tablet,
it will be interrupted after 10 minutes.

Switching to economy mode

Once this period has elapsed, a message
appears in the screen indicating that the
vehicle has switched to economy mode and the
active functions are put on standby.

Exiting economy mode

These functions are reactivated automatically
the next time the vehicle is driven.
F

In order to resume the use of these

functions immediately, start the engine and
let it run for a few minutes.

The time available to you will then be double
the period for which the engine is left running.
However, this period will always be between
five and thirty minutes.

Load reduction mode

System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as the air conditioning,
the heated rear screen...
The deactivated functions are reactivated
automatically as soon as conditions permit.

Practical information

Fitting roof bars

As a safety measure and to avoid damaging the
roof, it is essential to use the transverse bars
approved for your vehicle.

When fitting roof bars, use only the four fixing
points located in the roof frame. The points are
masked by the vehicle doors when closed.
Remove the protective covers, levering them
off with a screwdriver. Take care not to scratch
the paint.
The roof bar fixings include a stud to be fitted to
the hole at each fixing point.
Observe the fitting instructions and the
conditions of use in the guide supplied with the
bars.
Keep the protective covers safe so that they
can be refitted after removing the roof bars.

Maximum load distributed over the roof
bars, for a load height not exceeding
40 cm (except bicycle carriers):
- for roof bars with pads at 90 mm:

50 kg

- for roof bars with pads at 150 mm:

80 kg

For more information, contact a
CITROËN dealer or a qualified
workshop.
If the height exceeds 40 cm, adapt the
speed of the vehicle to the profile of the
road to avoid damaging the roof bars
and the fixings on the vehicle.

Be sure to refer to national legislation in
order to comply with the regulations for
transporting objects which are longer
than the vehicle.

Longitudinal roof bars are fitted as
original equipment to certain versions.
These play a purely aesthetic role and
transverse roof bars must not be fitted
to these longitudinal bars.

Checking levels

Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless otherwise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.

Engine oil level

It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 kms).

The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.

Take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns)
and the cooling fan could start at any
time (even with the ignition off).

The location of the dipstick is shown in the
corresponding underbonnet layout view.
F

Take the dipstick by its coloured grip and

remove it completely.

Wipe the end of the dipstick using a clean

non-fluffy cloth.

= MAX

= MIN

If you find that the level is above the A mark or
below the B

mark, do not start the engine.

If the level is above the MAX

mark (risk

of damage to the engine), contact a
CITROËN dealer or a qualified workshop.

If the level is below the MIN

mark, you

must top up the engine oil.

To ensure that the reading is correct,
your vehicle must be parked on a level
surface with the engine having been off
for more than 30 minutes.

Oil grade

Before topping up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.

Checking using the dipstick

Refit the dipstick and push fully down, then

pull it out again to make the visual check:
the correct level is between the marks A
and B.

246

Practical information

Power steering fluid level

The power steering fluid level should
be close to the "MAX" mark. With
the engine cold, unscrew the cap to
check the level.

Brake fluid level

Changing the fluid

Refer to the manufacturer's service schedule
for details of the interval for this operation.

Fluid specification

The brake fluid must conform to the
manufacturer's recommendations.

The brake fluid level should be close
to the "MAX" mark. If it is not, check
the brake pad wear.

Topping up the engine oil level

The location of the oil filler cap is shown in the
corresponding underbonnet layout view.
F

Unscrew the oil filler cap to reveal the filler

aperture.

Add oil in small quantities, avoiding any

spills on engine components (risk of fire).

Wait a few minutes before checking the

level again using the dipstick.

Add more oil if necessary.

After checking the level, carefully refit the

oil filler cap and the dipstick in its tube.

After topping up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel is not valid
during the 30 minutes after topping up.

Engine oil change

Refer to the manufacturer's service schedule
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.

247

Practical information

Coolant level

Check the coolant level regularly.
It is normal to top up this fluid
between services.

To ensure that the measurement is reliable, the
vehicle must be parked on level ground and the
engine must be cold.

The cooling fan may start after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades.

The coolant level should be close to the "MAX"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up.
A low coolant level presents a risk of serious
damage to your engine.

When the engine is hot, the temperature of the
coolant is regulated by the fan.

When the engine is hot, as the cooling system is
pressurised, wait at least one hour after switching
off the engine before carrying out any work.
To avoid the risk of scalding in the event of
an urgent need to top up, with a cloth around
the cap, unscrew it by two turns to allow the
pressure to drop.
Once the pressure has dropped, remove the
cap and top up the level.

Fluid specification

The coolant must conform to the
manufacturer's recommendations.

248

Practical information

To check the level or top up the
fluid on vehicle fitted with headlamp
washers, immobilise the vehicle and
switch of the engine.

Screenwash / headlamp wash fluid level

Open the bonnet and secure it with the

stay.

Specification of the fluid

To ensure optimum cleaning and to avoid
freezing, the fluid should never be topped up or
replaced by plain water.
In wintry conditions, the use of a fluid
with an ethyl alcohol or methanol base is
recommended.

Open the screenwash reservoir filler cap.

Take and pinch the level gauge to block its

breather.

Remove the gauge completely from

the reservoir to read the level in the
transparent section.

Top up if necessary.

Refit the filler cap to the reservoir and

close the bonnet.

Additive level

(Diesel with particle filter)

Topping up

The reservoir must be topped up without delay
by a CITROËN dealer or a qualified workshop.

Used products

Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.

Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.

According to your version of instrument panel,
the additive reservoir low level is indicated by:

- fixed illumination of the particle

filter warning lamp, accompanied
by an audible signal and a
message that the particle filter
additive level is too low,

- fixed illumination of the service

warning lamp, accompanied by
an audible signal and a message
that the particle filter additive
level is too low.

250

Practical information

Particle filter (Diesel)

According to your version of instrument panel, the start of
saturation of the particle emissions filter is indicated by:

- temporary illumination of

the service warning lamp,
accompanied by an audible signal
and a message that there is a risk
of blockage of the particle filter.

- fixed illumination of the particle

filter warning lamp, accompanied
by an audible signal and a
message that there is a risk of
blockage of the particle filter,

As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 40 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, there is a lack of
additive.

Checking components

Air filter and passenger compartment filter

Oil filter

Unless otherwise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Otherwise, have them checked by a CITROËN dealer or a qualified workshop.

Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.

Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.

Versions equipped with Stop &
Start are fitted with a 12 V lead-acid
battery of specific technology and
specification.
Its replacement should be carried
out only by a CITROËN dealer or a
qualified workshop.

12 V battery

For more information and the precautions to
take before starting work on the 12 V battery,
refer to the corresponding section.

The battery does not require any maintenance.
However, check regularly that the
terminals are correctly tightened
(versions without quick release terminals)
and that the connections are clean.

Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them twice as often
if necessary

A clogged passenger compartment filter may
have an adverse effect on the performance
of the air conditioning system and generate
undesirable odours.

For more information on Checking
the levels

and in particular on the

diesel additive level, refer to the
corresponding section.
On a new vehicle, the first operations
of regeneration of the particle filter
may be accompanied by the smell of
"burning", which is perfectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.

Manual gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for the checking interval for
this component.

Automatic gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for the checking interval for
this component.

Brake disc wear

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.

Brake pads

Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to have
the condition of the brakes checked,
even between vehicle services.

Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.

252

Practical information

Electric parking brake

This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a CITROËN dealer or a
qualified workshop.

Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.

Parking brake

If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.

For more information on the Electric parking
brake

, refer to the corresponding section.

Checking this system must be done by a
CITROËN dealer or a qualified workshop.

Once the AdBlue

tank is empty,

a system required by regulations
prevents starting of the engine.
If the SCR system is faulty, the level
of emissions from your vehicle will no
longer meet the Euro 6 standard: your
vehicle becomes polluting.
In the event of a confirmed fault
with the SCR system, you must go
to a CITROËN dealer or a qualified
workshop as soon as possible: after
a running distance of 650 miles
(1 100 km), a system will be triggered
automatically to prevent engine
starting.
In either case, a range indicator gives
you the distance you can travel before
the vehicle is immobilised.

AdBlue

and SCR system

for BlueHDi Diesel engines

To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
performance or fuel consumption of Diesel
engines, CITROËN has taken the decision to
equip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust gases.

SCR system

Using a fluid called AdBlue

containing urea, a

catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment.

The AdBlue

is held in a special tank with

a capacity of about 17 litres: this provides
a driving range of about 12 500 miles
(20 000 km). An alert is triggered automatically
to warn you when the reserve level is
reached: you can then drive about 1 500 miles
(2 400 km) before the tank is empty.

During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue

tank is refilled in order to allow

normal operation of the SCR system.

If the estimated mileage of your vehicle
between two services is greater than
12 500 miles (20 000 km), it will be necessary
to top-up the AdBlue

254

Practical information

Topping-up the AdBlue

Precautions in use

Keep AdBlue

out of the reach of

children, in its original container or
bottle.
Never transfer AdBlue

to another

container: it would lose its purity.

Never dilute AdBlue

with water.

Never pour AdBlue

into the Diesel fuel

tank.

Never top up from an AdBlue

dispenser reserved for heavy goods
vehicles.

AdBlue

is a urea-based solution. This liquid is

non-flammable, colourless and odourless (kept
in a cool area).
In the event of contact with the skin, wash
the affected area with soap and running
water. In the event of contact with the eyes,
wash (irrigate) the eyes with large amounts of
water or with an eye wash solution for at least
15 minutes. If a burning sensation or irritation
persists, get medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high exterior temperature,
for example), the risk of release of ammonia
cannot be excluded: do not inhale the fluid.
Ammonia vapour has an irritant effect on
mucous membranes (eyes, nose and throat).

Filling the AdBlue

tank is an operation

included in every routine service on your
vehicle by a CITROËN dealer or a qualified
workshop.
Nevertheless, given the capacity of the tank, it
may be necessary to top-up the fluid between
services, more particularly if an alert (warning
lamps and a message) signals the requirement.
You can go to a CITROËN dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.

Use only AdBlue

fluid that meets the

ISO 22241 standard.

The supply in a non-drip container or bottle
simplifies topping up. You can obtain 1.89 litre
(half a US gallon) bottles or 5 or 10 litre
containers from a CITROËN dealer or a
qualified workshop.

Freezing of the AdBlue

AdBlue

freezes at temperatures below

around -11°C.
The SCR system includes a heater
for the AdBlue

tank, allowing you

to continue driving in all weather
conditions.
