injured. Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won't
move: you can put blocks at the front and
rear

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of damage
caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
The MaxiFuses are located in
two fuse blocks, one in
the engine compartment and the other under the
rear seat. If a MaxiFuse should blow, have your vehicle
serviced by your dealer immediately.
Removing Fuses
You will find a fuse puller attached in both of the fuse
blocks. Snap the wide end of the fuse puller on
to
the fuse, at the side indentations holding the puller and
pull the fuse
out.
Engine Compartment Fuse Block
The engine compartment
fuse block is located in the
front
of the engine
compartment on the
passenger’s side. Lift the
cover
to gain access.
Fuse
22 or 23 can be moved to the outer position to
enable the accessory power outlet or cigarette lighter
when the ignition is not on. See your dealer for
additional assistance,
if needed.

Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment.
All recommended maintenance procedures
are important. Improper vehicle maintenance can
even affect the quality of the air we breathe. Improper
fluid levels or the wrong tire inflation can increase
the level of emissions from your vehicle.
To help protect
our environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended fluids and lubricants as prescribed in this
manual are necessary to keep your vehicle in good
working condition. Any damage caused by failure
to follow recommended maintenance may not be
covered by warranty.
