G WARNING

The front-passenger front airbag does not deploy during an accident.

This poses an increased risk of injury.

X Stop the vehicle safely as soon as possible, paying attention to road

and traffic conditions.

X Secure the vehicle against rolling away ( Y page 166).

X Switch the ignition off.

X Have the vehicle occupant on the front-passenger seat step out of

the vehicle.

R a self-diagnosis is carried out. The PASSENGER AIR BAG OFF and

PASSENGER AIR BAG ON indicator lamps must light up simulta-

If these conditions are met, the front-passenger seat can be occupied

again. Whether the PASSENGER AIR BAG OFF or ON indicator lamp

remains lit or goes out depends on how the automatic front-passenger

front airbag deactivation system classifies the vehicle occupant.

If the conditions are not met, the system is not operating correctly.

Some systems carry out a self-diagnosis when the ignition is switched on. Several warning and

indicator lamps can thereby temporarily light up or flash. This behaviour is non-critical. These
