parts. See “Engine Specications”
underCapacities and Specifications
on page 5-98for your vehicle’s
engine code.

Model designation
Paint information
Production options and special
equipment
Do not remove this label from the
vehicle.
Electrical System
High Voltage Devices and
Wiring
{CAUTION
Exposure to high voltage can
cause shock, burns, and even
death. The high voltage systems
in your vehicle can only be
serviced by technicians with
special training.
High voltage devices are identied
by labels. Do not remove, open,
take apart, or modify these
devices. High voltage cable or
wiring has orange covering. Do not
probe, tamper with, cut, or modify
high 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’s battery, even if the vehicle
is not operating.

Windshield Wiper Fuses
The windshield wiper motor is
protected by a circuit breaker and a
fuse. If the motor overheats due
to heavy snow or ice, the wiper will
stop until the motor cools. If the
overload is caused by some
electrical problem, have it xed.
Power Windows and
Other Power Options
Circuit breakers in the fuse block
protect the power windows and
other power accessories. When the
current load is too heavy, the
circuit breaker opens and closes,
protecting the circuit until the
problem is xed or goes away.
Fuses and Circuit
Breakers
The wiring circuits in your vehicle are
protected from short circuits by
a combination of fuses, circuit
breakers and fusible thermal links.
This greatly reduces the chance of
res 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.
Fuses of the same amperage can be
temporarily borrowed from another
fuse location, if a fuse goes out.
Replace the fuse as soon as
you can.
Instrument Panel Fuse
Block
The instrument panel fuse block is
located under the instrument
panel on the passenger side of the
vehicle. Pull down on the cover
to access the fuse block.
