FUSES
WARNING!
•When replacing a blown fuse, always use an appro-
priate 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 material. Do not
place a fuse inside a circuit breaker cavity or vice
versa. 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 disengaged.
• If the replaced fuse blows again, contact an autho-
rized dealer.
• If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, transmission system) or steering
system blows, contact an authorized dealer.

The Power Distribution Center is located in the engine
compartment near the battery. This center contains car-
tridge fuses, micro fuses, relays, and circuit breakers. A

WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic, pull far enough off the
road to avoid being hit when operating the jack or

3. Turn on the Hazard Warning flasher.
4. Apply the parking brake.
5. Turn the ignition OFF.

• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be
raised.
• Set the parking brake firmly and set the transmission
in PARK.
• Never start or run the engine with the vehicle on a
jack.
• Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it is on a jack. If
you need to get under a raised vehicle, take it to a

extension tube only. Use of an air wrench or other power
tools is not recommended and can damage the winch.
