Curtain airbags
System which protects the driver andpassengers (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 theside of the head.
Each curtain airbag is built into the pillars andthe upper passenger compartment area.

Deployment

The cur tain airbag is deployed at the same
time as the corresponding lateral airbag in the event of a serious side impact applied to all or par t 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 cur tain airbag inflates between the front or
rear occupant of the vehicle and the windows.
Operating fault
In the event of a minor impact or bump on the side of the vehicle or if the vehicle rolls over, the airbag may not be deployed.
In the event of a rear or front collision, the airbag is not deployed.
I
f this warning lamp comes on in theinstrument panel, accompanied by
an audible signal and a message in
the screen, contact a CITROËN dealer or a
qualified workshop to have the system checked.
The airbags may no longer be deployed in the
event of a serious impact.

For the airbags to be fully effective, observe the following safety rules:
Front airbags
Do not drive holding the steering wheel by its spokes or resting your hands on the centre par t of the wheel.
Passengers must not place their feet on thedashboard.
If possible, do not smoke as deployment of the airbags can cause burns or the risk of injury from a cigarette or pipe.
Never remove or pierce the steering wheel or hit it violently.



Lateral airbags

Use only approved covers on the seats,compatible with the deployment the lateral airbags. For information on the range of seat covers suitable for your vehicle, you cancontact a CITROËN dealer (see "Practicalinformation - § Accessories").
Do not fix or attach anything to the seat backs (clothing...). This could cause injury to the chest or arms if the lateral airbag isdeployed.
Do not sit with the upper par t of the body any nearer to the door than necessary.


Curtain airbags

Do not fix or attach anything to the roof. This could cause injury to the head if thecurtain airbag is deployed.
If fitted on your vehicle, do not remove the grab handles installed on the roof, they play a par t in securing the cur tain airbags.


Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the occupantsand the airbags (a child, pet, object...). This could hamper the operation of the airbags or injure the occupants. After an accident or if the vehicle has beenstolen or broken into, have the airbagsystems checked. All work on the airbag system must be carriedout by a CITROËN dealer or a qualified workshop.
Even if all of the precautions mentioned are obser ved, a risk of injury or of minor burns to the head, chest or arms when an airbag is deployed cannot be ruled out. The
bag inflates almost instantly (within a few milliseconds) then deflates within the sametime discharging the hot gas via openings provided for this purpose.

Electric parking brake
The electric parking brake combines
2 operational modes:- Automatic Application/ReleaseApplication is automatic when the engine
stops, release is automatic on use of the
accelerator (activated by default),-Manual Application/ReleaseThe parking brake can be applied/releasedmanually by pulling control lever A.

Do not place any object (packet of cigarettes, telephone...) between thegear lever and the electric parkingbrake control lever.


It is recommended that you do notapply the parking brake in very coldconditions (ice) and during towing (breakdown, caravan...). Deactivate the automatic functions and release the parking brake manually.
If this warnin
g lamp comes on in
the instrument panel, the automatic
m
ode is deactivated.
Programming the mode

Depending on the country of sale of the vehicle,
the automatic application when the engine is
switched off and the automatic release whenyou press the accelerator can be deactivated.

Activation/deactivation is done
using the vehicle configurationmenu; refer to the section covering
the configuration of your vehicle'ssystems.

The parking brake is then applied and released
manually. When the driver's door is opened,
there is an audible si
gnal and a message is
displayed if the brake is not applied.

Maximum application is essential:

- in the case of a vehicle towing a caravan
or a trailer, if the automatic functions are
activated but you are applying the parkingbrake manually,

- when the gradient you are parked on may
vary (e.g. on a ferry, on a lorry, duringtowing).

In the case of towing, a loaded vehicle or parking on a gradient, make amaximum application of the parkingbrake then turn the front wheelstowards the pavement and engage agear when you park.
