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. 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.

Vehicle Care 10-31
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
fires 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.
Engine Compartment
Fuse Block
The underhood fuse block is located
in the engine compartment, on the
passenger side of the vehicle.
Lift the cover for access to the
fuse/relay block.Notice:
Spilling liquid on any
electrical component on the
vehicle may damage it. Always
keep the covers on any electrical
component.
To remove fuses, hold the end of
the fuse between your thumb and
index finger and pull straight out.

Vehicle Care 10-83
Dinghy Towing
If the vehicle is front-wheel‐drive, it
can be dinghy towed from the front.
These vehicles may also be towed
by putting the front wheels on a
dolly. See“Dolly Towing” later in this
section. If the vehicle is all‐wheel‐drive, it
can be dinghy towed from the front.
These vehicles can also be towed
by placing them on a platform trailer
with all four wheels off of the
ground. These vehicles cannot be
towed using a dolly.
For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each
RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components. Reinstall
the fuse to start the vehicle.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to be
towed, shift the transmission to
P (Park), and turn the ignition
to LOCK/OFF.
2. Secure the vehicle to the towing vehicle.
3. Set the parking brake.
4. Turn the ignition to ACC/ACCESSORY.
5. Shift the transmission to N (Neutral).

10-84 Vehicle Care
6. To prevent the battery fromdraining while the vehicle is
being towed, remove the
20 amp ECM1 fuse and the
50 amp BATT1 fuse from the
underhood fuse block and store
in a safe location. See Engine
Compartment Fuse Block on
page 10‑31.
7. Release the parking brake.
Notice: If the vehicle is towed
without performing each of the
steps listed under “Dinghy
Towing,” the automatic
transmission could be damaged.
Be sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.
Notice: If 105 km/h (65 mph) is
exceeded while towing the
vehicle, it could be damaged.
Never exceed 105 km/h (65 mph)
while towing the vehicle. Once the destination is reached:
1. Set the parking brake.
2. Reinstall the fuses in the
underhood fuse block.
3. Shift the transmission to P (Park), turn the ignition to
LOCK/OFF and remove the key
from the ignition.
4. Disconnect the vehicle from the towing vehicle.
Notice: Do not tow a vehicle with
the front drive wheels on the
ground if one of the front tires is
a compact spare tire. Towing with
two different tire sizes on the
front of the vehicle can cause
severe damage to the
transmission.Dolly Towing (All-Wheel‐Drive
Vehicles)
All-wheel‐drive vehicles must not be
towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground or dinghy towed
from the front.
