Electrical System
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 or labels. 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 the
following in the vehicle:
.Headlamp wiring
.Windshield wiper motor
.Power windows and other power
accessories
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 the wiper control
