Notes on achieving optimum airbag
effectiveness
WARNING
If the seat position is wrong or the deployment
area of the airbag is restricted, the airbag sys‐
tem cannot provide the intended protection or
may cause additional injuries when it deploys.
There is a danger of injury or even death. Ob‐
serve the following to achieve optimum protec‐
tive effect.
▷ Keep your distance from the airbags.
▷ Always grip the steering wheel on the steer‐
ing wheel rim. Place your hands in the
3 o'clock and 9 o'clock positions to minimise
the risk of injury to hands or arms when the
airbag deploys.
▷ Make sure that the front-seat passenger is
sitting correctly, in other words with feet or
legs in the footwell, not resting on the dash‐
board.
▷ Make sure that vehicle occupants keep their
head away from the side airbag.
▷ Do not position any other persons, pets or
objects between the airbags and persons.
▷ Keep the dashboard and windscreen in the
area of the passenger's side free, for example
do not attach adhesive foil or covers and do
not fit brackets for navigation devices or mo‐
bile telephones.
▷ Do not attach anything to the airbag covers
with adhesive; never cover them or modify
them in any way.

Safety
▷ Do not use the front airbag cover on the front
passenger's side as a tray.
▷ Covers, seat covers, cushions or other ob‐
jects not specifically suitable for seats with in‐
tegral side airbags must not be fitted to the
front seats.
▷ Do not hang items of clothing for example
coats or jackets over the backrests.
▷ Do not modify individual components of the
system or its wiring in any way. This also ap‐
plies to the covers of the steering wheel, the
dashboard and seats.
▷ Do not dismantle the airbag system.
Even if all this information is observed, depend‐
ing on the circumstances in which an accident
occurs, certain injuries as a result of contact with
the airbag cannot be entirely ruled out.
The noise caused by the deployment of an air‐
bag may lead to temporary hearing loss for vehi‐
cle occupants sensitive to noise.
