Never modify an air bag cover or affix objects
to it.
G WARNING
Sensors to control the air bags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Alway sh ave work on the doors or door pan-
eling carried out at aq ualifie ds pecialist work-
shop.
Front air bags
! Do not place heavy objects on the front-
passenger seat. This could cause the system
to identify the seat as being occupied .Int he
event of an accident, the restraint systems on
the front-passenger side may be triggered
and have to be replaced.
Driver's air bag C deploys in front of the steer-
ing wheel .F ront-passenger front air bag D
deploys in front of and above the glove box.
When deployed, the front air bags offer addi-
tional head and thorax protection for the occu-
pants in the driver's and front-passenger seats.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps inform you about
the status of the front-passenger air bag
( Y
page 38). The front-passenger front air bag wil lo nly
deplo yi f: R
the system, based on the OCS weight sensor
readings, detects that the front-passenger
seat is occupied ( Y
page 44). The
PASSENGER AIR BAG ON indicator lamp is lit
( Y
page 45) R
the restraint system control unit predicts a
high accident severity
Kne eb ags
Driver's knee bag C deploys under the steering
column and front-passenger knee bag D under
the glove box. The driver's and front-passenger
knee bags are triggered together with the front
air bags.
The driver's and front-passenger knee bags
offer additional thigh, knee and lowe rl eg pro-
tection.
Side impact air bags
G WARNING
Unsuitabl es eat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they are
designed to do. In addition, the operatio no f
the occupant classification system (OCS)
could be adversel ya ffected. This poses an
increased risk of injury or even fatal injury.
You shoul do nly use seat covers that have
been approve df or the respective seat by
