Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be
driven to a safe place in an emergency. Should an
hot engine condition exist, an overheat protection
mode which alternates ring groups of cylinders
helps prevent engine damage. In this mode, there is
a loss in power and engine performance. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss and change the oil. SeeEngine Oil on
page 360.
Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Electric Engine Cooling Fans
B. Coolant Surge Tank and Pressure Cap
Some vehicles may be equipped with an
engine driven fan, as well as the electric
pusher fans (A) which are located behind the
vehicle’s grille.

The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 471.
When rotating P255/50R20 size tires, always use
the correct rotation pattern shown here.
Do not include the compact spare tire in the tire
rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
Tire and Loading Information label.Vehicles that have the Tire Pressure Monitor
System (TPMS) will need to have the TPMS
sensors reset after a tire rotation, seeTire
Pressure Monitor System on page 410.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 464.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 424.

Notice:If your vehicle has a tire size other
than P255/50R20 use tire chains only where
legal and only when you must. Use chains that
are the proper size for your tires. Install
them on the tires of the rear axle. Do not use
chains on the tires of the front axle. Tighten
them as tightly as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions. If you
can hear the chains contacting your vehicle,
stop and retighten them. If the contact
continues, slow down until it stops. Driving
too fast or spinning the wheels with chains on
will damage your vehicle.If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the at tire will create a drag
that pulls the vehicle toward that side. Take your
foot off the accelerator pedal and grip the
steering wheel rmly. Steer to maintain lane
position, and then gently brake to a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout
remove your foot from the accelerator pedal. Get
the vehicle under control by steering the way
you want the vehicle to go. It may be very bumpy
and noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.
423

{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after time. The
wheel could come off and cause an
accident. When you change a wheel,
remove any rust or dirt from the places
where the wheel attaches to the vehicle. In
an emergency, you can use a cloth or a
paper towel to do this; but be sure to use
a scraper or wire brush later, if needed, to
get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or nuts.
If you do, the nuts might come loose.
Your wheel could fall off, causing a
serious accident.
10. Install the spare tire.
11. Put the wheel nuts back on with the rounded
end of the nuts toward the wheel.
12. Tighten each nut by hand until the wheel is
held against the hub.
433

Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly equipped with a secondary latch
system. It is designed to stop the compact spare
tire from suddenly falling off your vehicle if the
cable holding the spare tire is damaged. For the
secondary latch to work, the tire must be
stowed with the valve stem pointing down. See
Storing a Flat or Spare Tire and Tools on page 439
for instructions on storing the spare tire correctly.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack. If
the spare tire does not slide off the jack
completely, make sure no one is behind
you or on either side of you as you pull
the jack out from the under spare.
436

To store the spare tire and tools, do the following:
1. Lay the compact spare tire on the ground
at the rear of the vehicle. Position the
compact spare tire so that the valve stem is
pointed down facing the rear of the vehicle.
2. Lower the cable to the ground. SeeRemoving
the Spare Tire and Tools on page 426.3. Tilt the retainer downward and slip it through
the center hole of the spare tire.
Make sure the retainer is fully seated across
the underside of the wheel.
4. Attach the wheel wrench to the hoist shaft.
5. Turn the wheel wrench clockwise to lift
the spare tire.
6. When the tire is almost in the stored position,
turn the tire so that the valve stem is towards
the rear of the vehicle.
This will help when you check and maintain
tire pressure in the spare.
7. Raise the tire fully against the underside of
the vehicle. Continue turning the wheel
wrench until you feel more than two clicks.
This indicates that the compact spare
tire is secure and the cable is tight. The spare
tire hoist cannot be overtightened.
441

Fabric/Carpet
Use a vacuum cleaner with a soft brush
attachment frequently to remove dust and loose
dirt. A canister vacuum with a beater bar in
the nozzle may only be used on oor carpet and
carpeted oor mats. For soils, always try to remove
them rst with plain water or club soda. Before
cleaning, gently remove as much of the soil
as possible using one of the following techniques:
For liquids: gently blot the remaining soil
with a paper towel. Allow the soil to absorb into
the paper towel until no more can be
removed.
For solid dry soils: remove as much as
possible and then vacuum.
To clean, use the following instructions:
1. Saturate a lint-free, clean white cloth with
water or club soda.
2. Wring the cloth to remove excess moisture.3. Start on the outside edge of the soil and
gently rub toward the center. Continue
cleaning, using a clean area of the cloth each
time it becomes soiled.
4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a
mild soap solution and repeat the cleaning
process that was used with plain water.
If any of the soil remains, a commercial fabric
cleaner or spot lifter may be necessary. When a
commercial upholstery cleaner or spot lifter is to be
used, test a small hidden area for colorfastness
rst. If the locally cleaned area gives any
impression that a ring formation may result, clean
the entire surface.
After the cleaning process has been completed, a
paper towel can be used to blot excess moisture
from the fabric or carpet.
445

All cleaning agents should be ushed promptly
and not allowed to dry on the surface, or they
could stain. Dry the nish with a soft, clean
chamois or an all-cotton towel to avoid surface
scratches and water spotting.
High pressure car washes may cause water to
enter the vehicle.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and
a car washing soap to clean exterior lamps
and lenses. Follow instructions underWashing
Your Vehicle on page 447.
Finish Care
Occasional waxing or mild polishing of the vehicle
by hand may be necessary to remove residue
from the paint nish. Approved cleaning products
can be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 452.Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
nish may damage it. Use only non-abrasive
waxes and polishes that are made for a
basecoat/clearcoat paint nish on your vehicle.
The vehicle has a basecoat/clearcoat paint
nish. The clearcoat gives more depth and gloss
to the colored basecoat. Always use waxes
and polishes that are non-abrasive and made for a
basecoat/clearcoat paint nish.
Foreign materials such as calcium chloride and
other salts, ice melting agents, road oil and
tar, tree sap, bird droppings, chemicals from
industrial chimneys, etc., can damage the vehicle’s
nish if they remain on painted surfaces. Wash
the vehicle as soon as possible. If necessary, use
non-abrasive cleaners that are marked safe for
painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging,
weather, and chemical fallout that can take their
toll over a period of years. To help keep the
paint nish looking new, keep the vehicle in a
garage or covered whenever possible.
448

Windshield and Wiper Blades
If the windshield is not clear after using the
windshield washer, or if the wiper blade chatters
when running, wax, sap, or other material may
be on the blade or windshield.
Clean the outside of the windshield with a glass
cleaning liquid or powder and water solution.
The windshield is clean if beads do not form when
it is rinsed with water.
Grime from the windshield will stick to the wiper
blades and affect their performance. Clean
the blade by wiping vigorously with a cloth soaked
in full-strength windshield washer solvent. Then
rinse the blade with water.
Check the wiper blades and clean them as
necessary; replace blades that look worn.
Aluminum or Chrome-Plated Wheels
Your vehicle may have either aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth
with mild soap and water. Rinse with clean water.
After rinsing thoroughly, dry with a soft clean
towel. A wax may then be applied.
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or
cleaners that contain acid on aluminum or
chrome-plated wheels, you could damage the
surface of the wheel(s). The repairs would
not be covered by your warranty. Use
only GM-approved cleaners on aluminum or
chrome-plated wheels.
The surface of these wheels is similar to the
painted surface of your vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because you could damage
the surface. Do not use chrome polish on
aluminum wheels.
