Deployment
* For more information on Deactivating the front passenger airbag , refer to the
corresponding section. The front airbag inflates between the thorax
and head of the front occupant of the vehicle
and the steering wheel, driver's side, and the
dashboard, passenger's side, to cushion their
for ward movement.
Lateral airbags
Deployment
Front airbags
System which protects the driver and front
passenger in the event of a
serious front
impact, in order to limit the risk of injury to the
head and thorax.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger's airbag is
fitted in the dashboard above the glove box.
The airbags are deployed, except the front
passenger airbag if it is deactivated*, in the
event of a
serious front impact to all or part
of the front impact zone A , in the longitudinal
centreline of the vehicle on a
horizontal plane
and directed from the front to the rear of the
vehicle. System which protects the driver and front
passenger in the event of a
serious side impact
in order to limit the risk of injury to the chest,
between the hip and the shoulder.
Each lateral airbag is fitted in the seat backrest
frame, door side.
It is deployed unilaterally in the event of
a
severe side impact covering all or part of side
impact zone B , perpendicular to the longitudinal
centreline of the vehicle on a
horizontal plane
and directed from the outside towards the
inside of the vehicle. The lateral airbag inflates between the hip and
shoulder of the front occupant of the vehicle
and the corresponding door trim panel.
Curtain airbags
System contributing towards greater protection
for the driver and passengers (with the
exception of the rear centre passenger) in the
event of a
serious side impact in order to limit
the risk of injury to the side of the head.
Each curtain airbag is built into the pillars and
the upper passenger compartment area.
Deployment
The curtain airbag is deployed at the same
time as the corresponding lateral airbag in the
event of a
serious side impact applied to all or
part of the side impact zone B , perpendicular
to the longitudinal centreline of the vehicle
on a
horizontal plane and directed from the
outside towards the inside of the vehicle.
The curtain airbag inflates between the front or
rear occupant of the vehicle and the windows.
Malfunction
If this warning lamp comes on in the
instrument panel, you must contact
a
CITROËN dealer or a qualified
workshop to have the system
checked.
Safety

114
The warning label present on both sides of the
passenger sun visor repeats this advice.
In line with current legislation, you will find this
warning in all the required languages in the
following tables.

F

R
emove the key keeping the switch in the
new position.
When the ignition is switched on,
this warning lamp comes on in the
instrument panel. It stays on while
the airbag is deactivated. To ensure the safety of your child, the front
passenger airbag must be deactivated
when you install a
"rear ward facing" child
seat on the front passenger seat.
Otherwise, the child risks being seriously
injured or killed if the airbag is deployed.
Reactivating the front passenger
airbag
When you remove the "rear ward facing" child
seat, with the ignition off , turn the switch to
the ON position to reactivate the airbag and so
assure the safety of your front passenger in the
event of an impact.
When the ignition is switched on,
this warning lamp comes on in the
instrument panel, for approximately
one minute to signal that the front
airbag is activated.
Safety

127
In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
t emperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a trailer before having driven at least
approximately 620


miles (1,000

kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
adjustment , refer to the corresponding
section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
This electronic engine immobiliser locks the
engine management system a
few moments
after the ignition is switched off, and prevents
starting of the engine by anyone who does not
have the key.
In the event of a
malfunction, you are informed
by a
message in the instrument panel screen.
If this happens, your vehicle will not start;
contact a
CITROËN dealer if required.

Reactivation of automatic operation is
confirmed by the indicator lamp in the
instrument panel going off.
Emergency braking
The emergency braking should only be
used in an exceptional situation. In the event of a
failure of the main ser vice
brake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc.), a continuous
pull on the control lever will brake the vehicle.
Braking takes place while the control lever is
being pulled. It is interrupted if the control lever
is released.
The ABS and DSC systems ensure stability of
the vehicle during emergency braking.
If the emergency braking malfunctions,
the message "Parking brake fault" will be
displayed.
If the ABS and DSC systems malfunction,
signalled by the illumination of one or both
warning lamps in the instrument panel, then
stability of the vehicle is no longer guaranteed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release"
actions on the control lever until the vehicle is
immobilised.
Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a
gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal. This system only operates when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-
c
ertain slope conditions are met,
-
t
he driver's door is closed.
The hill start assist system cannot be
deactivated.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If you need to get out of the vehicle with
the engine running, apply the parking
brake manually. Then verify that the
parking brake warning lamp (and the
warning lamp P on the electric parking
brake control lever) are on continuously.

Changing from one gear to another only
occurs if the vehicle speed and engine speed
conditions allow; other wise the gearbox will
operate temporarily in automatic mode.
If the engine speed is too low or too high, the
gear selected flashes for a few seconds, then
the gear actually engaged is displayed.

Operating fault
If the gearbox malfunctions, the
Ser vice warning lamp comes on in
the instrument panel, accompanied
by a
message and an audible signal. Do not exceed 62
mph (100 km/h), local speed
restrictions permitting.
Have it checked by a CITROËN dealer or
a

qualified workshop.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may then
feel a

substantial jolt when changing from P to
R and from N to R . This jolt will not cause any
damage to the gearbox.
Gear efficiency indicator
This system reduces fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
Gear efficiency recommendations are for
information only. In fact, the road layout, the
traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued
by the system.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode.
