Seating and Safety Restraints
Turning the passenger airbag off
1. Insert the ignition key, turn the
switch to OFF position and hold in
the OFF position while removing the
key.
2. When the ignition is turned to the
on position the "pass airbag off"
light illuminates briefly, momentarily
shuts off and then turns back on.
This indicates that the passenger
airbag is deactivated.
WARNING: If the light fails to illuminate when the passenger air
bag switch is in the OFF position and the ignition switch is in
on, have the passenger air bag switch serviced at your authorized
dealer immediately.
WARNING: In order to avoid inadvertent activation of the
switch, always remove the ignition key from the passenger air
bag ON/OFF switch.
WARNING: An infant in a rear-facing seat faces a high risk of
serious or fatal injuries from a deploying passenger airbag. Rear
facing infant seats should NEVER be placed in the front seats, unless
the passenger airbag is turned off.
