automatically to preserve the remaining battery
charge.
Switching off the engine leads to a loss
of braking assistance.
Starting the engine
Parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then depress the clutch pedal fully.
► With an automatic gearbox, place the gear
selector in mode N or P then depress the brake
pedal fully.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
pre-heating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to two minutes (accelerated idle
speed).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, which secret code must be
recognised in order for starting to be possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact the CITROËN dealer.
Starting / Switching off the
engine with the key
Key ignition switch

It has 3 positions:
– position 1 (Stop): inserting and removing the
key, steering column locked.
–
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating, engine
running,
–
position 3 (Starting).
Avoid attaching heavy objects to the key
or the remote control, which would weigh
down on its blade in the ignition switch and
could cause a malfunction.
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops to
the reserve level, the system switches to energy
economy mode : the power supply is cut off

Switching off the engine leads to a loss
of braking assistance.
Starting the engine
Parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then depress the clutch pedal fully.
►

With an
automatic gearbox, place the gear
selector in mode N or P then depress the brake
pedal fully.

Unlock
the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
►

With a
petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
pre-heating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to two minutes (accelerated idle
speed).
► With a Diesel engine, turn the key to position
2, ignition on, to operate the engine pre-heating
system.
Wait until this warning lamp goes off in the
instrument panel, then operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
In wintry conditions, the warning lamp
may stay on for a longer period. When
the engine is hot, the warning lamp does not
come on.
If the engine does not start straight away,
switch off the ignition. Wait a few
seconds before operating the starter motor
again. If the engine does not start after
several attempts, do not keep trying: you risk
damaging the starter motor and the engine.
Contact a CITROËN dealer or a qualified
workshop.
In mild conditions, do not leave the
engine at idle to warm up but move off
straight away and drive at moderate speed.
Switching off the engine
► Stop the vehicle.
► With the engine running in idle, turn the key
to position
1.
►

Remove the key from the ignition switch.
► To lock the steering column, turn the steering
wheel until it locks.
To facilitate unlocking of the steering column, it is recommended that the
wheels be returned to the straight ahead
position before switching off the engine.
►

Check that the parking brake is correctly
applied, particularly on sloping ground.
Never switch off the ignition before the
vehicle is at a complete stop. With the
engine off, the braking and steering
assistance systems are also cut off: risk of
loss of control of the vehicle.
When you leave the vehicle, keep the
key with you and lock the vehicle.
Energy economy mode
After switching off the engine (position 1 - Stop),
for a maximum of 30 minutes you can still
use functions such as the audio and telematic
system, the wipers, dipped beam headlamps,
courtesy lamps, etc.

driver's door closes again.
Deactivating automatic
operation
In some situations, for example when it is
extremely cold or when towing (e.g. caravan,
breakdown), it may be necessary to deactivate
automatic operation of the system.
►

Start the engine.
►


Use the control lever to apply the parking
brake, if it is released.
►


T
ake your foot fully off the brake pedal.
►

Hold the control lever pressed in the release
direction for between 10 and a maximum of 15
seconds.
►


Release the control lever
.
►

Depress and hold the brake pedal.
►


Pull the control lever in the application
direction for 2

seconds.
This indicator lamp on the instrument panel comes on to confirm deactivation of
the automatic functions.
►

Release the control lever and the brake
pedal.
From now on, the parking brake can only be
applied and released manually using the control
lever

.
Repeat this procedure to reactivate automatic
operation (confirmed by the indicator lamp on the
instrument panel going off).
Emergency braking
In the event of a fault with the brake pedal or
in an exceptional situation (e.g. driver taken ill,
driver under instruction), a continuous pull on the
electric parking brake control lever will brake the
vehicle. Braking continues while the control lever
is pulled, and ceases when the control lever is
released.
The ABS and DSC systems stabilise the vehicle
during emergency braking.
If emergency braking malfunctions, the message
"Parking brake control faulty" will be displayed
on the instrument panel.
If the ABS and DSC systems
malfunction, indicated by lighting
one or both warning lamps on the instrument
panel, the vehicle’s stability is no longer ensured.
In this event, the driver must keep the vehicle
stable by successively pulling and releasing the
control lever, repeating the operation until the
vehicle has stopped.
6-speed manual gearbox
Engaging reverse gear

► Raise the trigger under the knob and move
the gear lever to the left, then forwards.
Only engage reverse gear when the
vehicle is stationary with the engine at
idle.
As a safety precaution and to facilitate starting of the engine, always select
neutral and depress the clutch pedal.
Engaging 5th or 6th gear
► Move the lever fully to the right to engage 5th
or 6th gear.
Failure to follow this advice may cause
permanent damage to the gearbox
(engagement of 3
rd or 4th gear by mistake).
