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
position in accordance with these
instructions and warnings. Failure
to put the switch in a proper
position can increase the risk of
serious injury or death in a
collision.
Turning the passenger airbag off
1. Insert the ignition key, turn the
switch to OFF position and hold in
OFF position while removing the
key.
2. When the ignition is turned to the
ON position the OFF light
illuminates briefly, momentarily
shuts off and then turns back on.
This indicates that the passenger
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.

If your vehicle has rear seats, always transport children who are
12 and younger in the rear seat. Always use safety belts and
child restraints properly. If a child in a rear facing infant seat must be
transported in front, the passenger airbagmustbe turned OFF. This is
because the back of the infant seat is too close to the inflating airbag
and the risk of a fatal injury to the infant when the airbag inflates is
substantial.
The vast majority of drivers and passengers are much safer with an
airbag than without. To do their job and reduce the risk of life
threatening injuries, airbags must open with great force, and this force
can pose a potentially deadly risk in some situations, particularly when a
front seat occupant is not properly buckled up. The most effective way
to reduce the risk of unnecessary airbag injuries without reducing the
overall safety of the vehicle is to make sure all occupants are properly
restrained in the vehicle, especially in the front seat. This provides the
protection of safety belts and permits the airbags to provide the
additional protection they were designed to provide. If you choose to
deactivate your airbag, you are losing the very significant risk reducing
benefits of the airbag and you are also reducing the effectiveness of the
safety belts, because safety belts in modern vehicles are designed to
work as a safety system with the airbags.
Read all airbag warning labels in the vehicle as well as the other
important airbag instructions and warnings in this Owner’s Guide.
NHTSA deactivation criteria (excluding Canada)
1.Infant.An infant (less than 1 year old) must ride in the front seat
because:
•the vehicle has no rear seat;
•the vehicle has a rear seat too small to accommodate a rear-facing
infant seat; or
•the infant has a medical condition which, according to the infant’s
physician, makes it necessary for the infant to ride in the front so that
the driver can constantly monitor the child’s condition.
2.Child age 1 to 12.A child age 1 to 12 must ride in the front seat
because:
•the vehicle has no rear seat;
•although children ages 1 to 12 ride in the rear seat(s) whenever
possible, children ages 1 to 12 sometimes must ride in the front
because no space is available in the rear seat(s) of the vehicle; or
