Safety5
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. 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. Do not fit or attach anything to the steering wheel or dashboard, this could cause injuries with deployment of the airbags.
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. Refer to the "Accessories" section. 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 part 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 curtain airbag is deployed. If fitted on your vehicle, do not remove the grab handles installed on the roof, they play a part in securing the curtain 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...), nor fix or attach anything close to the inflation trajectory of the airbags; this could cause injuries during their deployment. Never modify the original definition of your vehicle, particularly in the area directly around the airbags. 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 observed, 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.
