Practical information
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.
/
Release procedure
► With the vehicle stationary and the engine
running, depress the brake pedal and select
mode
N.
Within 5
seconds:
►

Depress and hold the brake pedal, then
observe this order: switch off the engine and
move the push selector forwards or backwards.
►


Release the brake pedal, then switch on the

Advice on care and maintenance
General recommendations
Observe the following recommendations to avoid
damaging the vehicle.
Exterior
Never use a high-pressure jet wash in
the engine compartment - risk of
damaging the electrical components!
Do not wash the vehicle in bright sunshine or
extremely cold conditions.
When washing the vehicle in an
automatic roller-brush car wash, be sure
to lock the doors and, depending on version,
move the electronic key away.
When using a pressure washer, keep the jet
nozzle at a minimum distance of 30 cm from
the vehicle (particularly when cleaning areas
containing chipped paint, sensors or seals).
Promptly clean up any stains containing
chemicals liable to damage the vehicle's
paintwork (including tree resin, bird
droppings, insect secretions, pollen and tar).
Depending on the environment, clean the
vehicle frequently to remove salty deposits
(in coastal areas), soot (in industrial areas)
and mud/salts (in wet or cold areas). These
substances can be highly corrosive.
Contact a CITROËN dealer or a qualified
workshop for advice on removing stubborn
stains requiring special products (such as tar
or insect removers).
Preferably, have paint touch-ups performed
by a CITROËN dealer or a qualified
workshop.
Interior
When washing the vehicle, never use a
water hose or high-pressure jet to clean
the interior.
Liquids carried in cups or other open
containers can spill, presenting a risk of
damage to the instruments and controls and
the controls located on the centre console. Be
vigilant!

175
In the event of a breakdown
8The 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.
Automatic gearbox
Never try to start the engine by pushing
the vehicle.
Electric motor
Flat accessory battery
It is no longer possible to start the motor
or recharge the traction battery.
Precautions before working on the
accessory battery
Select mode
P, switch off the ignition, check
that the instrument panel is off and that the
vehicle is not being charged.
Jump-starting another vehicle
Do not use the accessory battery to
jump-start another vehicle or to charge
another vehicle's battery.
Symbols
No sparks or naked flames, no smoking.
Always protect your eyes. Explosive gases can cause blindness and injury.
Keep the vehicle's battery out of the reach
of children.
The vehicle's battery contains sulphuric acid which can make you go blind or
cause severe burns.

178
In the event of a breakdown
Reconnecting the (+) terminal

► Raise lever A fully.
► Refit open clamp B on the (+) terminal.
►

Push clamp
B fully down.
►

Lower lever

A
to lock clamp B.
►

Depending on equipment, lower the plastic
cover on the

(+) terminal.
Do not force the lever when pressing on
it, as if the clamp is not positioned
correctly, locking will then not be possible.
Start the procedure again.
Following reconnection
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, to enable the electronic systems to
initialise.
If minor problems nevertheless persist following
this operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the relevant section, reinitialise
certain equipment:
–

Remote control key or electronic key
(depending on version).
–

Sunroof.
–

Electric windows.
–


Date and time.
–


Preset radio stations.
The Stop & Start system may not be operational during the trip following the
first engine start.
In this case, the system will only be available
again after a continuous period with the
vehicle immobilised, the duration of which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).
Towing the vehicle
General recommendations
Observe the legislation in force in the
country where you are driving.
Ensure that the weight of the towing vehicle is
higher than that of the towed vehicle.
The driver must remain at the wheel of the
towed vehicle and must have a valid driving
licence.
When towing a vehicle with all four wheels on
the ground, always use an approved towing
arm; rope and straps are prohibited.
The towing vehicle must move off gently.
When the vehicle is towed with its engine
off, there is no longer braking and steering
assistance.
A professional towing service must be
called if:
–

Broken down on a motorway or main road.
–


Not possible to put
the gearbox into neutral,
unlock the steering, or release the parking
brake.
–

Not possible to tow a vehicle with an
automatic gearbox, with the engine running.
–


T

owing with only two wheels on the ground.
–

Four-wheel drive vehicle.
–


No approved towbar available.
Before towing the vehicle, it is essential
to put the vehicle in free-wheeling mode.
For more information on Free-wheeling, refer
to the corresponding section.
Electric motor
An electric vehicle cannot under any
circumstances be used to tow another
vehicle.
However, it may be used, for example, to exit
a rut.
