{WARNING:
You can be injured and the vehicle could be
damaged if you try to do service work on a vehicle
without knowing enough about it.
•Be sure you have sufficient knowledge,
experience, the proper replacement parts,
and tools before attempting any vehicle
maintenance task.
•Be sure to use the proper nuts, bolts, and
other fasteners. English and metric fasteners
can be easily confused. If the wrong fasteners
are used, parts can later break or fall off.
You could be hurt.
If doing some of your own service work, use the proper
service manual. It tells you much more about how to
service the vehicle than this manual can. To order
the proper service manual, seeService Publications
Ordering Information on page 8-15.This vehicle has an airbag system. Before attempting
to do your own service work, seeServicing Your
Airbag-Equipped Vehicle on page 2-71.
Keep a record with all parts receipts and list the
mileage and the date of any service work performed.
SeeMaintenance Record on page 7-13.
Adding Equipment to the Outside of
the Vehicle
Things added to the outside of the vehicle can affect the
airflow around it. This can cause wind noise and can
affect fuel economy and windshield washer performance.
Check with your dealer/retailer before adding equipment
to the outside of the vehicle.

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 6-14
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it
again, keeping the tip down and check the level.

Electrical System
Intermediate Voltage Devices and
Wiring
{WARNING:
Exposure to intermediate voltage can cause shock
and burns. The intermediate voltage systems in
the vehicle can only be serviced by technicians
with special training.
Intermediate voltage devices are identified by
labels. Do not remove, open, take apart, or modify
these devices. Intermediate voltage cable or wiring
has blue covering. Do not probe, tamper with, cut,
or modify intermediate voltage cable or wiring.
Add-On Electrical Equipment
Notice:Do not add anything electrical to the
vehicle unless you check with your dealer/retailer
rst. Some electrical equipment can damage
the vehicle and the damage would not be covered
by the vehicle’s warranty. Some add-on electrical
equipment can keep other components from
working as they should.
Add-on equipment can drain the vehicle battery, even if
the vehicle is not operating.
The vehicle has an airbag system. Before attempting to
add anything electrical to the vehicle, seeServicing Your
Airbag-Equipped Vehicle on page 2-71andAdding
Equipment to Your Airbag-Equipped Vehicle on
page 2-72.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due
to heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem, have it fixed.

Power Windows and Other Power
Options
Fuses in the fuse block protect the power windows.
When the current load is too heavy, the fuse opens
protecting the circuit until the problem is fixed.
Fuses
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible links. 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
to replace a bad fuse with a new one of the identical
size and rating.
There are three fuse blocks in your vehicle: one in the
center of the instrument panel, one in the engine
compartment and one in the trunk.
There is a fuse puller located on the instrument panel
fuse block. It can be used to easily remove fuses
from the fuse block.
Instrument Panel Fuse Block
The instrument panel fuse block is located on the
passenger side of the vehicle, on the lower portion of
the instrument panel near the floor.
Remove the panel cover to access the fuse block, then
remove the fuse block cover to access the fuses.
Your vehicle might not have all the fuses and features
listed.
