Practical information
Oil grade
Before topping up or changing the
engine oil, check that the oil is suitable
for your engine and complies with the
recommendations in the service schedule
supplied with the vehicle (or available from
your CITROËN dealer or qualified workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►

Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►


W
ait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
The oil level indication displayed on the instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the brake
pads for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
(Petrol or Diesel)
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the " MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
(Electric)
Do not top up the coolant.
If the level is close to or below
the "MIN" mark, it is essential to contact a
CITROËN dealer or a qualified workshop.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).

Practical information
7The system only registers AdBlue®
intermediate top-ups of 5

litres or more.
If the AdBlue® tank is completely empty
– which is confirmed by the message
“Top up AdBlue: Starting impossible ” – it is
essential to add at least 10
litres.
Top-up detection may not be instantaneous
after addition. It may take a few minutes of
driving before the top-up detection is effective.
Changing to free-wheeling
In certain situations, it is necessary to put the
vehicle into free-wheeling mode (e.g. towing, on
a rolling road, automatic car wash (Wash mode),
rail or sea transport).
The procedure varies according to the type of
gearbox and parking brake.
Never leave the vehicle unattended with
the vehicle into free-wheeling mode.
Keyless Entry and Start
You must not depress the brake pedal
while switching the ignition on again, then
switching it off. If you do, the engine will start,
requiring you to restart the procedure.

engine and select mode P .
Advice on care and maintenance
General recommendations
Observe the following recommendations to avoid
damaging the vehicle.

187
In the event of a breakdown
8After changing a wheel
With a "space-saver" type spare wheel
Deactivate certain driving aid functions
(Active Safety Brake, Adaptive cruise control,
etc.).
Do not exceed the maximum authorised
speed of 50 mph (80 km/h).
Driving with more than one "space-saver"
type spare wheel is prohibited.
Visit a CITROËN dealer or a qualified
workshop.
Have the tightening of the spare wheel's bolts
and its tyre pressure checked.
Have the punctured tyre examined. After
inspection, the technician will advise you on
whether the tyre can be repaired or if it must
be replaced.
Changing a bulb
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
Never look too closely at the light beam
of LED technology lamps - risk of serious
eye injury!


The headlamps have polycarbonate lenses with a protective coating:
–

Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
–


Use a sponge and soapy water or a pH
neutral product.
–


When using a high-pressure washer on
persistent marks, do not keep the lance
directed towards the headlamps, lamps or
their edges for too long, so as not to damage
their protective coating and seals.
Changing a bulb must only be done with
the ignition off and after the headlamp /
lamp has been switched off for several
minutes - risk of serious burns!
Do not touch the bulb directly with your
fingers; use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
Refitting the lamp units
Perform the operations in the reverse
order to dismantling.

Fuses
Changing a fuse
All work must be carried out only by a
CITROËN dealer or a qualified workshop
The replacement of a fuse by a third party
could cause a serious malfunction of the
vehicle.
Installing electrical accessories
The vehicle's electrical system is
designed to operate with standard or optional
equipment.
Before fitting other electrical equipment
or accessories to your vehicle, contact a
CITROËN dealer or a qualified workshop.
CITROËN accepts no responsibility for
the cost incurred in repairing the vehicle
or for rectifying malfunctions resulting from
the installation of accessories not supplied or
not recommended by CITROËN and not
installed in accordance with its
recommendations, in particular when the
combined power consumption of all of the
additional equipment connected exceeds 10
milliamperes.
12 V battery / Accessory
battery
Lead-acid starter batteries
These batteries contain harmful
substances (sulphuric acid and lead).
They must be disposed of in accordance
with regulations and must never under any
circumstances be discarded with household
waste.
Dispose of used batteries at a designated
collection point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be carried
out in a well ventilated area and away from
naked flames and sources of sparks, to avoid
any risk of explosion or fire.
Wash your hands afterwards.
Frozen battery
Never try to charge a frozen battery - risk
of explosion!
If the battery has frozen, have it checked by a
CITROËN dealer or by a qualified workshop,
who will verify that the internal components
have not been damaged and that the case
has not cracked, which could lead to a risk of
leakage of toxic and corrosive acid.
