Maintaining Your Air Bag System
WARNING!

Modifications to any part of the air bag
system could cause it to fail when you need
it. You could be injured if the air bag
system is not there to protect you. Do not
modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper passenger side of the
instrument panel. Do not modify the front
bumper, vehicle body structure, or add
aftermarket side steps or running boards.

It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function properly
if modifications are made. Take your
vehicle to an authorized dealer for any air
bag system service. If your seat,
including your trim cover and cushion,
needs to be serviced in any way
(including removal or loosening/
tightening of seat attachment bolts),
take the vehicle to an authorized dealer.
Only manufacturer approved seat
accessories may be used. If it is
necessary to modify the air bag system
for persons with disabilities, contact an
authorized dealer.

FUSES
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must
check the fuse element inside the blade fuse
for a break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery
discharge.
CAUTION!
Do not touch the new bulb with your
fingers. Oil contamination will severely
shorten bulb life. If the bulb comes in
contact with any oily surface, clean the
bulb with rubbing alcohol.
WARNING!
When replacing a blown fuse, always use
an appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a blown
fuse with metal wires or any other mate-
rial. Failure to use proper fuses may
result in serious personal injury, fire and/
or property damage.
Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen -
gaged.
If the replaced fuse blows again, contact
an authorized dealer.
If a general protection fuse for safety
systems (air bag system, braking
system), power unit systems (engine
system, gearbox system) or steering
system blows, contact an authorized
dealer.
CAUTION!
If it is necessary to wash the engine
compartment, take care not to directly hit
the fuse box, and the windshield wiper
