Passenger airbag ON/OFF switch (if equipped)
An airbag ON/OFF switch
has been installed in this
vehicle. Before driving,always
look at the face of the switch to
be sure the switch is in the proper

airbag is deactivated.
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.
In order to avoid inadvertent activation of the switch, always
remove the ignition key from the passenger air bag ON/OFF
switch.
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.
