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

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.

Tire inflation information
All tires with Steel Carcass Plies (if equipped):
This type of tire utilizes steel cords in the sidewalls. As such, they
cannot be treated like normal light truck tires. Tire service, including
adjusting the air pressure, must be performed by personnel trained,
supervised and equipped according to Federal Occupational Safety and
Health Administration (OSHA) regulations. For example, during any
procedure involving tire inflation, the technician or individual must
utilize a remote inflation device, and ensure that all persons are clear of
the trajectory area.
WARNINGAn inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To avoid serious injury,
never attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly
for inspection. Do not attempt to add air to tires or replace tires or
wheels without first taking precautions to protect persons and
property.
