Electrical System High Voltage Devices and
Wiring
{ WARNINGExposure 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
identified 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. Fuses and Circuit
Breakers The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses, circuit
breakers and fusible thermal links.
This greatly reduces the chance of
fires caused by electrical problems.
Be sure you replace a bad fuse with
a new one of the identical size and
rating.
If you ever have a problem on the
road and do not have a spare fuse,
you can borrow one that has the
same amperage. Just pick some
feature of the vehicle that you can
get along without, like the radio or
cigarette lighter, and use its fuse,
if it is the correct amperage.
Replace it as soon as you can.
The vehicle also has a special fuse
in the battery box for the 300-volt
batteries. If this fuse has failed and
needs to be replaced, the vehicle
will be disabled and you will need to have the vehicle repaired by your
dealer. Do not attempt to
self-service this fuse.

pressure to operate effectively.
Notice: Do not let anyone tell
you that under ‐ inflation or
over ‐ inflation is all right. It is
not. If your tires do not have
enough air (under ‐ inflation),
you can get the following: .
Tire overloading and
over-heating which could
lead to a blowout. .
Premature or
irregular wear. .
Poor handling. .
Reduced fuel economy. If your tires have too much air
(over ‐ inflation), you can get
the following: .
Unusual wear. .
Poor handling. .
Rough ride. .
Needless damage from
road hazards. A vehicle specific Tire and Loading
Information label is attached to your
vehicle. This label shows your
vehicle's original equipment tires
and the correct inflation pressures
for your tires when they are cold.
The recommended cold tire inflation
pressure, shown on the label, is the
minimum amount of air pressure
needed to support your vehicle's
maximum load carrying capacity.
