g wheel ››› Fig. 20 and the airbag
for the front passenger is located in the dash

word “AIRBAG”.
When the driver and front passenger airbags
are deployed, the covers remain attached to
the steering wheel and dashboard, respec-
tively ››› Fig. 20 ››› Fig. 21.
In conjunction with the seat belts, the front
airbag system gives the front occupants ad-
ditional protection for the head and chest in the event of a severe frontal collision
›››
in
Fr ont
airb
ags on page 87.
Their special design allows the controlled es-
cape of the propellant gas when an occupant
puts pressure on the bag. Thus, the head and
chest are protected by the airbag. After the
collision, the airbag deflates sufficiently to
allow visibility.

s of the driver seat ››› Fig. 26 and the
front passenger seat as well as in the back-
rest of the side rear seats*. The locations are
identified by the text “AIRBAG” in the upper
region of the backrests. In conjunction with the seat belts, the side
airbag sys

tem provides additional protection
for the upper body in the event of a severe
side collision ››› in Side airbags* on
p ag
e 87

.
In a side collision, the side airbags reduce
the risk of injury to passengers to the areas
of the body facing the impact. In addition to
their normal function of protecting the occu-
pants in a collision, the front and rear outer
seat belts also hold the passengers in the
event of a side collision; this is how these air-
bags provide maximum protection.
