In the event of a breakdown

► Remove the bolts and store them in a clean place.► Remove the wheel.
Stowing the damaged wheel► To stow an alloy wheel , first remove
the wheel trim from the centre of the wheel so
that the fastening device (nut and bolt) can be
put in place.
► In the case of a "space saver" type
spare wheel, the damaged wheel cannot be
stowed under the floor. It must be placed in
the boot; use a cover to protect the inside of
the boot.

VHOHFWPRGHP
to lock the wheels, apply the parking brake,
unless it is programmed to be in automatic
mode, and switch off the ignition.
Check for the fixed illumination of the parking
brake indicator lamps in the instrument panel.
The occupants must get out of the vehicle
and wait where they are safe.
If necessary, place a chock under the wheel
diagonally opposite the wheel to be changed.
Never go underneath a vehicle raised using a
jack; use an axle stand.
Wheel with wheel trim
When removing the wheel , first remove
the wheel trim by pulling at the valve aperture
using the wheelbrace.
When refitting the wheel , refit the wheel
trim, starting by placing its aperture in line
with the valve and then pushing it into place
all round its edge with the palm of your hand.


– If the vehicle has steel wheels, remove the wheel trim.– If the vehicle has alloy wheels, remove the central bolt cover using tool 7.– If the vehicle is so equipped, fit security bolt socket 2 to wheelbrace 5 to slacken the security
bolt.
– Slacken the other bolts using the wheelbrace 5 only.

► Place the foot of jack 6 on the ground and ensure that it is directly below the front A or rear B jacking point on the underbody, whichever
is closest to the wheel to be changed.


► Extend jack 6 until its head comes into contact with jacking point A or B; contact area A
or B on the vehicle must be properly inserted
into the central part of the head of the jack.
► Raise the vehicle until there is sufficient space between the wheel and the ground to
admit the spare (not punctured) wheel easily.
Ensure that the jack is stable. If the
ground is slippery or loose, the jack may
slip or collapse - risk of injury!
Take care to position the jack strictly at
one of the jacking points A or B under the
vehicle, ensuring that the head of the jack is
centred under the contact area of the vehicle.
Otherwise, there is a risk of damage to the
vehicle and/or of the jack collapsing - risk of
injury!

Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or a battery booster.
Never try to start the engine by
connecting a battery charger.
Never use a 24 V or higher battery booster.
Check beforehand that the backup battery
has a nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact with
each other.
Switch off all the electrical consumers on both
vehicles (audio system, wipers, lighting, etc.).
Make sure that the jump leads are not close
to moving parts of the engine (fan, belts, etc.).
Do not disconnect the (+) terminal while the
engine is running.


► Lift the plastic cover on the (+) terminal, if your vehicle has one.► Connect the red cable to the positive terminal (+) of flat battery A (at the metal elbow) then to
the positive terminal (+) of backup battery B or
the booster.
► Connect one end of the green or black cable to the negative terminal (-) of backup battery B
or the booster (or an earth point on the other
vehicle).
► Connect the other end of the green or black cable to earth point C on the broken down
vehicle.
► Start the engine of the vehicle with the good battery and leave it running for a few minutes.► Operate the starter on the broken down vehicle and let the engine run.
If the engine does not start straight away, switch
off the ignition and wait a few moments before
trying again.
► Wait until the engine returns to idle then disconnect the jump lead cables in the reverse
order.

In the event of a breakdown
8At the battery, it is only necessary to disconnect
the (+) terminal.
Quick-release terminal clamp
Disconnecting the (+) terminal

► Raise the lever A fully to release the clamp
B.
► Remove the clamp B by lifting it off.
Reconnecting the (+) terminal


► Raise the lever A fully.► Refit the open clamp B on the (+) terminal.► Push the clamp B fully down.► Lower the lever A to lock the clamp B.
Do not force the lever as locking will not
be possible if the clamp is not positioned
correctly; start the procedure again.
Following reconnection of the battery
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, in order to enable the electronic systems
to initialise.
For right-hand drive vehicles, when the
total distance recorder has reached 37
miles (60 km), it is necessary to wait approx.
15 minutes before starting the engine.
However, if minor problems persist following
this operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the corresponding section, you must
yourself reinitialise or reset certain systems,
such as:
– the key with remote control or electronic key (depending on version),– the sunroof and its electric blind,– the electric windows,– the date and time,– the 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 of
immobilisation of the vehicle, a period which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).
