indicated level mark.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight.
6. Verify coolant level after the engine is shut off and the
coolant is cold. If necessary,
repeat coolant fill procedure
Steps 1–6.
If the coolant still is not at the
proper level when the system
cools down again, see your
dealer.
Caution
If the pressure cap is not tightly
installed, coolant loss and engine
damage may occur. Be sure the
cap is properly and tightly
secured.
Engine Overheating
The vehicle has an engine coolant
temperature gauge on the
instrument cluster to warn of engine
overheating. See Engine Coolant
Temperature Gauge 0121.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. Contact
your dealer for additional
information.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, do not continue
to run the engine, and have the
vehicle serviced.

leak in the engine cooling system.
This can cause a loss of all (Continued)

system and vehicle. Have any
leaks fixed right away.
If Steam Is Coming from the
Engine Compartment
{Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.

Tire Chains
{Warning
If the vehicle has 225/45R17 or
P225/40R18 size tires, do not use
tire chains. There is not enough
clearance. Tire chains used on a
vehicle without the proper amount
of clearance can cause damage
to the brakes, suspension,
or other vehicle parts. The area
damaged by the tire chains could
cause loss of control and a crash.
Use another type of traction
device only if its manufacturer
recommends it for the vehicle's
tire size combination and road
conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels. If
traction devices are used, install
them on the front tires.
Caution
If the vehicle is equipped with
195/65R15 or 205/55R16 size
tires, use tire chains only where
legal and only when necessary.
Use low profile chains that add no
more than 12 mm thickness to the
tire tread and inner sidewall. Use
chains that are the proper size for
the tires. Install them on the tires
of the front axle. Do not use
chains on the tires of the rear
axle. Tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and follow
the chain manufacturer's
instructions. If the chains contact
the 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 the
vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. SeeTires
0 270. If air goes out of a tire, it is
much more likely to leak out slowly.
But if there is ever 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.

14. Tighten the wheel nuts firmly ina crisscross sequence, as
shown.
15. Lower the jack all the way and remove the jack from under the
vehicle.
16. Tighten the wheel nuts firmly with the wheel wrench.
When reinstalling the wheel cover or
center cap on the full-size tire,
tighten all five plastic caps hand
snug with the aid of the wheel
wrench and tighten them with the
wheel wrench an additional
one-quarter of a turn.
Caution
Wheel covers will not fit on the
vehicle's compact spare. If you try
to put a wheel cover on the
compact spare, the cover or the
spare could be damaged.
Storing a Flat or Spare Tire
and Tools
{Warning
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place.

Tools —Vehicles with a Trunk
1. Replace the jack and tools in their original storage location.
2. Place the tire, lying flat, valvestem down in the spare
tire well.
3. Turn the retainer nut clockwise until tight.
4. Replace the load floor.
Storing a Flat Tire and Tools —
Vehicles with a Liftgate
The spare tire wheel well is not
designed to store a full size tire.
A damaged full size tire must be
stored on the load floor and secured
with the strap provided.
1. Replace the jack and tools in their original storage location.

door under the rear floor
storage cover.
3. Attach the loop end of the strapto the thread and secure it with
the wing nut.
4. Replace the load floor.
5. Place the tire, lying flat, valve stem up, on the right side of
the load floor.
6. Route the strap hook through
the wheel.
7. Route and attach the strap around the strut in the storage
compartment.
8. Tighten the strap and secure it using the buckle. Storing the Spare Tire and
Tools
—Vehicles with a Liftgate
Reverse the directions for removing
the jack, tools, and spare tire.
The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as you can.
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure
regularly. It should be 420 kPa
(60 psi).

6. Connect the other end of thered positive (+) cable to the
positive (+) terminal of the good
battery.
7. Connect one end of the black negative (–) cable to the
negative (–) terminal of the
good battery.
8. Connect the other end of the black negative (–) cable to the
negative (–) grounding terminal
for the discharged battery.
9. Start the engine in the vehicle with the good battery and run
the engine at idle speed for at
least four minutes.
10. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it
probably needs service.
Caution
If the jumper cables are
connected or removed in the
wrong order, electrical shorting

may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct order,
making sure that the cables do
not touch each other or other
metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle
and removing the jumper cables,
allow it to idle for several minutes.
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty. Do not lash
or hook to suspension
components. Use the proper
straps around the tires to secure
the vehicle. Do not drag a locked
wheel/tire while loading the
vehicle. Do not use a sling type
lift to tow the vehicle. This could
damage the vehicle.
GM recommends a flatbed tow truck
to transport a disabled vehicle. Use
ramps to help reduce approach
angles, if necessary. A towed
vehicle should have its drive wheels
off the ground. Contact Roadside
Assistance or a professional towing
service if the disabled vehicle must
be towed.
