240 Vehicle Care
{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.
Engine Coolant
The engine and Charged Air
Coolant (CAC) cooling systems in
the vehicle are filled with
DEX-COOL
®engine coolant
mixture. See Recommended Fluids
and Lubricants 0301 and
Maintenance Schedule 0297.
The following explains the cooling
systems and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating 0243.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too

hot but you would not get the
overheat warning. The engine
could catch fire and you or others
could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL coolant.
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. If using this mixture,
nothing else needs to be added.
This mixture:
. Gives freezing protection down
to−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Helps keep the proper engine
temperature.

Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement
parts. If this is not done, the brakes
may not work properly. The braking
performance expected can change
in many other ways if the wrong
replacement brake parts are
installed or parts are improperly
installed.
Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid as
indicated on the reservoir cap. See
Engine Compartment Overview
0230 for the location of the
reservoir. There are only two reasons why the
brake fluid level in the reservoir may
go down:
.
Normal brake lining wear. When
new linings are installed, the
fluid level goes back up.
. A fluid leak in the brake
hydraulic system. Have the
brake hydraulic system fixed.
With a leak, the brakes will not
work well.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove fluid, as
necessary, only when work is done
on the brake hydraulic system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light 0121.
Brake fluid absorbs water over time.
Replace brake fluid at the specified
intervals to prevent increased
stopping distance. See Maintenance
Schedule 0297.
What to Add
Use only GM approved DOT 3
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0301.

Vehicle Care 269
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated at the
intervals specified in the
Maintenance Schedule. See
Maintenance Schedule0297. Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. See
When It Is Time
for New Tires 0270 andWheel
Replacement 0273.
Use this rotation pattern when
rotating the tires.
Do not include the compact
spare tire in the tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure 0263 and Vehicle
Load Limits 0177.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation 0266.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications 0305.
{Warning
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

General Information
Caution
Maintenance intervals, checks,
inspections, recommended fluids,
and lubricants are necessary to
keep this vehicle in good working
condition. Damage caused by
failure to follow scheduled
maintenance might not be
covered by the vehicle warranty.
As the vehicle owner, you are
responsible for the scheduled
maintenance in this section. We
recommend having your dealer
perform these services. Proper
vehicle maintenance helps to keep
the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions for
better air quality.
Because of all the different ways
people use vehicles, maintenance
needs vary. The vehicle might need
more frequent checks and services.
Please read the information under Scheduled Maintenance. To keep
the vehicle in good condition, see
your dealer.
The maintenance schedule is for
vehicles that:
.
Carry passengers and cargo
within recommended limits on
the Tire and Loading Information
label. See Vehicle Load Limits
0 177.
. Are driven on reasonable road
surfaces within legal driving
limits.
. Use the recommended fuel. See
Fuel 0218.
{Warning
Performing maintenance work can
be dangerous. Some jobs can
cause serious injury. Perform
maintenance work only if you
have the required know-how and
the proper tools and equipment.
If in doubt, see your dealer to
have a qualified technician do the
work. See Doing Your Own
Service Work 0229.

Service and Maintenance 297
At your dealer, you can be certain
that you will receive the highest
level of service available. Your
dealer has specially trained service
technicians, uses genuine
replacement parts, as well as,
up-to-date tools and equipment to
ensure fast and accurate
diagnostics.
The proper replacement parts,
fluids, and lubricants to use are
listed inRecommended Fluids and
Lubricants 0301 andMaintenance
Replacement Parts 0302. We
recommend the use of genuine
parts from your dealer.
Rotation of New Tires
Tire rotation is not recommended if
the vehicle has different size tires
on the front and rear wheels. If tire
rotation is recommended for the
vehicle, to maintain ride, handling,
and performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every
service. See Tire Rotation 0269.Maintenance
Schedule
When the Change Engine Oil

When the CHANGE ENGINE OIL
SOON message displays, service is
required for the vehicle as soon as
possible, within the next 1 000 km/
600 miles. If driving under the best
conditions, the engine oil life system
