294 Vehicle Care
Engine Coolant
The cooling system in the vehicle isfilled with DEX-COOL®enginecoolant mixture. SeeRecommendedFluids and Lubricants0375andMaintenance Schedule0366.
The following explains the coolingsystem and how to check and addcoolant when it is low. If there is aproblem with engine overheating,seeEngine Overheating0296.
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
(Continued)
Warning (Continued)
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-COOLcoolant. If using this mixture,nothing else needs to be added.
This mixture:
.Gives freezing protection downto✓37 °C (✓34 °F) outsidetemperature.
.Gives boiling protection up to129 °C (265 °F) enginetemperature.
.Protects against rust andcorrosion.
.Will not damage aluminum parts.
.Helps keep the proper enginetemperature.
Caution
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
proper mixture of engine coolant
for the cooling system. See
Recommended Fluids and
Lubricants0375.
Never dispose of engine coolant byputting it in the trash, or by pouringit on the ground, or into sewers,streams or, bodies of water. Havethe coolant changed by anauthorized service center, familiarwith legal requirements regardingused coolant disposal. This will helpprotect the environment and yourhealth.

There are only two reasons why thebrake fluid level in the reservoir maygo down:
.Normal brake lining wear. Whennew linings are installed, thefluid level goes back up.
.Afluidleakinthebrake/clutchhydraulic system. Have thebrake/clutch hydraulic systemfixed. With a leak, the brakes willnot work well.
Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it.
Do not top off the brake/clutch fluid.Adding fluid does not correct a leak.If fluid is added when the linings areworn, there will be too much fluidwhen new brake linings areinstalled. Add or remove fluid, asnecessary, only when work is doneon the brake/clutch hydraulicsystem.
{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/clutch
hydraulic system.
When the brake/clutch fluid falls to alow level, the brake warning lightcomes on. SeeBrake SystemWarning Light0120.
Brake fluid absorbs water over timewhich degrades the effectiveness ofthe brake fluid. Replace brake fluidat the specified intervals to preventincreased stopping distance. SeeMaintenance Schedule0366.
What to Add
Use only GM approved DOT 3brake fluid from a clean, sealedcontainer. SeeRecommendedFluids and Lubricants0375.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.

12. Set all four tires to therecommended air pressurelevel as indicated on the Tireand Loading Information label.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
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 every
12 000 km (7,500 mi). See
Maintenance Schedule0366.
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. SeeWhen It Is Time
for New Tires0330andWheel
Replacement0334.
Use this rotation pattern when
rotating the tires.
Do not include the 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 Pressure0323andVehicle
Load Limits0226.
