Safety









Emergency braking assistance

System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.

Activation

It is triggered by the speed at which the brake
pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press
firmly without releasing the pressure.



















Trajectory control systems (ESP)


Anti-slip regulation (ASR)
and electronic stability
control (ESC)

The anti-slip regulation (also known as traction
control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability control acts on the
brake of one or more wheels and on the engine
to keep the vehicle on the trajectory required
by the driver, within the limits of the laws of
physics.


Activation

These systems are activated automatically
each time the vehicle is star ted.
They come into operation in the event of a grip
or trajectory problem.
This is indicated by flashing of this
warning lamp in the instrument panel.








Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving on
snow: intelligent traction control.

This system detects situations of difficult
sur face adhesion that could make it difficult to
move off or make progress on deep fresh snow
or compacted snow.
In these situations, the intelligent traction
control
limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.

The use of snow tyres is strongly
recommended on sur faces offering low
levels of adhesion.

Deactivation

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), if you are unable to make progress,
it may be advisable to temporarily deactivate
these systems, so that the wheels can spin
freely and allow the vehicle to move.


)
Press the "ESP OFF"
button,
located near the steering wheel.


Reactivation

These systems are reactivated automatically
each time the ignition is switched back on or
from 30 mph (50 km/h).


)
Press the "ESP OFF"
button again to
reactivate them manually.



Operating fault

The trajectory control systems offer
increased safety in normal driving, but
this should not encourage the driver to
take extra risks or drive at high speed.
The correct functioning of these
systems is assured provided that
manufacturer's recommendations are
observed on:


- wheels (tyres and rims),

- braking components,

- electronic components,

- assembly and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
If this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, this
indicates a fault with these systems.
Have it checked by a CITROËN dealer or a
qualified workshop. It is recommended that the systems be
reactivated as soon as possible.
If this warning lamp comes on in the instrument
panel and the indicator lamp in the button
comes on, this indicates that these systems are
deactivated.

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.
Deployment

The airbags are deployed simultaneously,
unless the passenger's front airbag is
deactivated, in the event of a serious front
impact to all or par t 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.
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.

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
part of the wheel.
Passengers must not place their feet on the
dashboard.
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 can
contact a CITROËN dealer (see "Practical
information - § 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 is
deployed.
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 the
cur tain 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 occupants
and 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 been
stolen or broken into, have the airbag
systems checked.
All work on the airbag system must be carried
out 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 same
time discharging the hot gas via openings
provided for this purpose.
