High Voltage Devices and
Wiring

{

WARNING

Exposure to high voltage
can cause shock, burns, and
even death. The high voltage
components in the vehicle can
only be serviced by technicians
with special training.

High voltage components are
identified by labels. Do not
remove, open, take apart,
or modify these components.
High voltage cable or wiring has
orange covering. Do not probe,
tamper with, cut, or modify high
voltage cable or wiring.

Electrical System
Overload

The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.

When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed.
This greatly reduces the chance
of circuit overload and fire caused
by electrical problems.

Fuses and circuit breakers protect
power devices in the vehicle.

Replace a bad fuse with a new one
of the identical size and rating.

If there is a problem on the road
and a fuse needs to be replaced,
the same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.

Headlamp Wiring

An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have
the headlamp wiring checked right
away if the lamps go on and off or
remain off.

Windshield Wipers

If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.

Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using
the windshield wipers.

If the overload is caused by an
electrical problem and not snow
or ice, be sure to get it fixed.
