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 theheadlamp 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.
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 in the
engine compartment, on the
passenger side of the vehicle.

Caution
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.

.The proper towing equipment.
See your dealer or trailering
professional for additional advice
and equipment
recommendations.
. If the vehicle is ready to be
towed. Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
Caution
Use of a shield mounted in front
of the vehicle grille could restrict
airflow and cause damage to the
transmission. The repairs would
not be covered by the vehicle
warranty. If using a shield, only
use one that attaches to the
towing vehicle.
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 the information on 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).
6. To prevent the battery from draining while the vehicle is
being towed, remove the
15 amp ECM fuse and the
15 amp OnStar fuse. These
are in the battery compartment
behind the passenger seat on
the floor. Also, remove the

302 Vehicle Care
50 amp BATT1 fuse from the
engine compartment fuse block
and store all fuses in a safe
location. SeeEngine
Compartment Fuse
Block 0261.
7. Release the parking brake.
Caution
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.
Caution
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.
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.
Caution
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.
