Driving and Operating
Engine Coolant Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below
18°C (0°F). Vehicles
with an engine heater should be
plugged in at least four hours before
starting. An internal thermostat in
the plug-end of the cord may exist
which will prevent engine coolant
heater operation at temperatures
above
18°C (0°F).
Using the Engine Coolant
Heater
1.
Turn off the engine.
2.
Open the hood and unwrap the
electrical cord. The cord is
secured to a wiring harness
between the engine and the
Hybrid Auxiliary Underhood
Fuse Block with a clip. Carefully
remove the wire tie which
secures the electrical cord.
Do not cut the electrical cord.
3.
Plug the cord into a normal,
grounded 110-volt AC outlet.
{
WARNING
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a fire. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4.
Before starting the engine, be
sure to unplug and store the
cord as it was before to keep it
away from moving engine parts.
If you do not, it could be
damaged.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.

Electrical System
High Voltage Devices and
Wiring
{
WARNING
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
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.
