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.
There are three fuse blocks in your vehicle: the
Instrument Panel Fuse Block located under the
instrument panel, the Underhood Fuse Block located on
the passenger’s side engine compartment, and the Rear
Fuse Block located under the rear seat.
Instrument Panel Fuse Block
The right side fuse panel is located under the
instrument panel.
Remove the hush panel to reveal the fuses.
To remove
the panel, remove the three screws located along the
rear edge of the panel. Place the wide end
of the fuse
puller over the plastic end
of the fuse. Squeeze the ends
over the fuse and pull it out.
>pare fuses are located
in the empty slots shown on the
following chart. When finished, replace
the hush panel. Replace lamps,
connectors, and HVAC duct temperature sensors if they
were removed.

Introduction
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 Schedule
I Short Trip/City Definition I ~ ~~
Follow the Short Trip/City Maintenance Schedule if any
one of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
0 If the vehicle is used for delivery service, police, taxi
your vehicle.
or other commercial application.
One of the reasons you should follow this schedule if
you operate
your vehicle under any of these conditions
is that these conditions cause engine oil to break
down soonez

off paved roads. Use the Short Trip/City schedule for

ProCarManuals.com

Short TripKity Maintenance Schedule
The services shown in this schedule up to 100,000 miles
(166
000 km) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at 150,000 miles (240
000 km) should be performed at
the same interval after 150,000 miles (240
000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or
limit recall liability prior to the
completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
# Lubricate the suspension, steering linkage, transaxle
shift linkage, parking brake cable guides and the
underbody contact points and linkage.
* If your vehicle has an Engine Oil Life Monitor, the
monitor will show you when to change the oil
-- usually
between
3,000 miles (5 000 km) and 7,500 miles
(12
500 km) since your last oil change. Under severe
conditions, the indicator may come on before
3,000 miles (5 000 km). Never drive your vehicle more
than
7,500 miles (12 500 km) or 12 months, (whichever
occurs first), without an oil change.
The system won’t detect dust in the oil.
So if you
drive in a dusty area be sure to change your oil every
3,000 miles (5 000 km) or sooner if the CHANGE OIL
light comes on. Remember to reset the Oil Life Monitor
when the oil has been changed. For more information,
see “Engine Oil Life Monitor” in the Index.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspection” in Part C of this schedule.
