Safety



► To select the system, at speeds below 31 mph (50 km/h), press this button until its indicator lights up; this lamp appears in green
in the instrument panel.
The system becomes active at speeds below 19
mph (30 km/h).► When the vehicle begins its descent, you can release the accelerator and brake pedals; the
system regulates the speed:
– if the gearbox is in first or second gear, the speed decreases and the indicator lamp flashes rapidly,– if the gearbox is in neutral or if the clutch pedal is depressed, the speed decreases and the
indicator lamp flashes slowly; in this case, the maintained descent speed is lower.
On a descent, with the vehicle stationary, if you
release the accelerator and brake pedals, the
system will release the brakes to set the vehicle
gradually in motion.
The brake lamps light up automatically when the
system is regulating.
If the speed exceeds 19 mph (30 km/h), regulation is paused automatically, the
indicator lamp goes back to grey in the instrument panel, but the green indicator lamp in
the button remains on.
Regulation resumes automatically when the
speed falls below 19 mph (30 km/h) again, if the slope and pedal release conditions are met.
You can depress the accelerator or brake pedal
again at any time.
Switching off


► Press this button until its indicator lamp goes off; the indicator goes off in the instrument panel.
Above 45 mph (70 km/h), the system is
automatically deactivated; the indicator lamp in
the button goes off.
Malfunction
In the event of a system malfunction, this warning lamp comes on on the instrument
panel, accompanied by an onscreen message.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Seat belts
Inertia reel
The seat belts are equipped with an inertia reel
which allows the strap length to automatically
adjust to your shape. The seat belt returns to its
storage automatically when it is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiter
This system reduces the pressure of the seat
belt on the chest of the occupant, thus improving
their protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. Deployment of the
pretensioners is accompanied by a slight
discharge of harmless smoke and a noise,
due to the activation of the pyrotechnic cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
Front seat belts

The front seat belts are fitted with a pyrotechnic
pretensioning system and a force limiting
system.

Starting the engine
With the parking brake applied:► With a manual gearbox, place the gear lever
in neutral then fully depress the clutch pedal.
► With an automatic gearbox, place the gear
selector in mode N or P then fully depress the
brake pedal.
► 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,
preheating the catalytic converter can
cause noticeable engine vibrations for anything up to 2 minutes while stationary with
the engine running (accelerated idle speed).
► With a Diesel engine, turn the key to position
2, ignition on, to operate the engine preheating
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 a few
attempts, do not keep trying - risk of
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.
