2009.5 Citroen DS3 wheel

Safety
Automatic operation of
hazard warning lamps
When braking in an emergency, depending on the deceleration, the hazard warning lamps come on automatically. They switch off automatically the first time you accelerate.  You can also switch them off by pressing the button.
Horn
Audible warning to aler t other road users to an imminent danger.  Press one of the spokes of the steering wheel.
Use the horn moderately and only in the following cases: - immediate danger, - when approaching an area where there is no visibility.

Braking assistance systems
Group of supplementary systems which help you to obtain optimum braking in complete safety in emergency situations: - anti-lock braking system (ABS), - electronic brake force distribution (EBFD), - emergency braking assistance (EBA).
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and manoeuvrability of your vehicle when braking, in par ticular on poor or slippery sur faces.
Activation
The anti-lock braking system comes into operation automatically when there is a risk of wheel lock. Normal operation of the ABS may make itself felt by slight vibration of the brake pedal.
When braking in an emergency, press very firmly without releasing the pressure.
Operating fault
If this warning lamp comes on, together with the STOP and ABSwarning lamps, accompanied by an audible signal and a message on the multifunction screen, it indicates a malfunction of the electronic brake force distribution which could result in loss of control of the vehicle when braking. You must stop as soon as it is safe to do so.
When replacing wheels (tyres and rims), ensure that they conform to the manufacturer's recommendations.
If this warning lamp comes on, accompanied by an audible signal and a message on the multifunction screen, it indicates a malfunction of the anti-lock braking system which could result in loss of control of the vehicle when braking.
In either case, contact a CITROËN dealer.

135Safety
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
Anti-skid regulation (ASR)
and electronic stability
programme (ESP)
The anti-skid 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 programme 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 on the instrument panel.

Deactivation
In exceptional conditions (star ting a vehicle which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate the ASR and ESP systems, so that the wheels can
move freely and regain grip.  Press the "ESP OFF" button, located on the left below the steering wheel.
If this warning lamp comes on in the instrument panel and the indicator lamp on the button comes on, this indicates that the ASR and ESP systems are deactivated.
Reactivation
These systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h) (except 1.6 litreTHP 150 petrol engine).
 Press the "ESP OFF" button again to reactivate them manually.
Operating fault
The ESP/ASR systems offer exceptional 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 depends on obser vation of the manufacturer's recommendations regarding the wheels (tyres and rims), the braking components, the electronic components and the CITROËN assembly and operation procedures. After an impact, have these systems checked by a CITROËN dealer.

141Safety
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 chest. The driver's airbag is incorporated in the centre of the steering wheel; the front passenger's airbag is incorporated in the dashboard above the glove box.
Activation
The airbags are triggered simultaneously, unless the passenger's front airbag is deactivated, in the event of a serious front impact applied 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 head-thorax of the front occupant of the vehicle and the dashboard to cushion their for ward
movement.

145Safety
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 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. These will not hinder inflation of the lateral airbags. Consult a CITROËN dealer. 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 triggered. 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 triggered. 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 is strictly forbidden unless it is carried out by qualified personnel of the CITROËN dealer network. 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 triggered 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.
