4. If the fuse must be replacedimmediately, borrow a
replacement fuse with the
same amperage from the
fuse block. Choose a vehicle
feature that is not needed
to safely operate the
vehicle. Repeat Steps 2–3.
5. Insert the replacement fuse into the empty slot of the
blown fuse.
At the next opportunity, see
your dealer to replace the
blown fuse.
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.
Fuses and Circuit
Breakers
The wiring circuits in the
vehicle are protected from
short circuits by a combination
of fuses and circuit breakers.
This greatly reduces the
chance of damage caused by
electrical problems.
{Danger
Fuses and circuit breakers
are marked with
their ampere rating. Do not
exceed the
specified amperage rating
when replacing fuses and
circuit breakers. Use of an
oversized fuse or circuit
breaker can result in a
vehicle fire. You and others
could be seriously injured or
killed.
{Warning
Installation or use of fuses
that do not meet GM’s
original fuse specifications is
dangerous. The fuses could
fail, and result in a fire. You (Continued)

Wheels and Tires
Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer.
See the warranty manual
for information regarding
the tire warranty and
where to get service. For
additional information refer
to the tire manufacturer.

Warning (Continued)
When replacing wheels, use
a new GM original
equipment wheel.
Caution
The wrong wheel can also
cause problems with bearing
life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle
ground clearance, and tire or
tire chain clearance to the
body and chassis.
Tire Chains
Caution
If the vehicle is equipped
with tire size 265/50R20,
use tire winter traction
devices only where legal and
only when necessary. Only
use textile traction devices,(Continued)
Caution (Continued)
such as tire snow socks,
that are the proper size for
the tires. Traction devices
must be installed only on the
tires of the drive axle. Drive
slowly and follow the
traction device
manufacturer’s instructions.
Driving too fast or spinning
the wheels can damage the
traction device.
If a Tire Goes Flat
It is unusual for a tire to blow
out while driving, especially if
the tires are maintained
properly. If air goes out of a
tire, it is much more likely to
leak out slowly. See Tires
0334 for additional
information. But if there ever
is a blowout, here are a few
tips about what to expect and
what to do:
If a front tire fails, the flat tire
creates a drag that pulls the
vehicle toward that side. Take your foot off the accelerator
pedal and grip the steering
wheel firmly. Steer to maintain
lane position, and then gently
brake to a stop, well off the
road, if possible.
A rear blowout, particularly on
a curve, acts much like a skid
and may require the same
correction as used in a skid.
Stop pressing the accelerator
pedal and steer to straighten
the vehicle. It may be very
bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
The vehicle has no spare tire,
no tire changing equipment,
and no place to store a tire.
If the vehicle has self-sealing
tires, see Self-Sealing Tires
0
336. Tread punctures
typically will not cause tires to
lose air. However, if the vehicle
does get a flat tire, there is no
spare tire, tire changing
equipment, or place to store a
tire. Contact Roadside Service
0 388 for help.
