Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-24.
A 50/50 mixture of clean, drinkable water and proper
coolant will:
•Give freezing protection down to−34°F (−37°C).
•Give boiling protection up to 265°F (129°C).
•Protect against rust and corrosion.
•Help keep the proper engine temperature.
•Let the warning lights and gages work as they
should.
What to Use
Use a 50/50 mixture of clean, drinkable water and coolant
that meets GM Specification 1825M, which will not
damage aluminum parts. You can also use a recycled
coolant conforming to GM Specification 1825M with a
complete coolant flush and refill. If you use this coolant
mixture, you do not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and the proper coolant.
Notice:If you use an improper coolant mixture, your
engine could overheat and be badly damaged. The
repair cost would not be covered by your warranty.
Too much water in the mixture can freeze and crack
the engine, radiator, heater core, and other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
5-22

Adding Coolant
If the level falls below the Minimum (B) mark, add the
proper coolant mixture at the surge tank, but only when
the engine is cool. If the surge tank is empty, a
special fill procedure is necessary. SeeCooling System
on page 5-26for instructions on “How to Add Coolant
to the Coolant Surge Tank.”
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-28.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood. Stay
away from the engine if you see or hear steam
coming from it. Just turn it off and get
everyone away from the vehicle until it cools
down. Wait until there is no sign of steam or
coolant before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re. You
or others could be badly burned. Stop your
engine if it overheats, and get out of the
vehicle until the engine is cool.
5-24

{CAUTION:
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 re, and you could be
burned. Get any leak xed before you drive the
vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan is running. If
the engine is overheating, the fan should be running. If
it is not, your vehicle needs service.
Notice:Engine damage from running your engine
without coolant is not covered by your warranty.
How to Add Coolant to the Coolant
Surge Tank
Notice:This vehicle has a specic coolant ll
procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.
If you have not found a problem yet, check to see if
coolant is visible in the surge tank. If coolant is visible
but the coolant level is not between the Minimum
and Maximum marks, add a 50/50 mixture of clean,
drinkable water and proper coolant at the coolant surge
tank, but be sure the cooling system, including the
coolant surge tank pressure cap, is cool before you do
it. SeeEngine Coolant on page 5-22for more
information.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your GM Warranty booklet for details. For additional
information refer to the tire manufacturer’s booklet
included with your vehicle.{CAUTION:
Poorly maintained and improperly used tires
are dangerous.
Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out and a
serious accident. SeeLoading Your
Vehicle on page 4-27.
Underinated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold. SeeInflation - Tire
Pressure on page 5-51.
Overinated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.

an instrument cluster gage connected to the VSS on the transaxle output shaft. The trip odometer can be reset to
zero at any time so that the driver can record the distance traveled from any starting point.
Fuel Gage
The fuel gage consists of an instrument cluster gage connected to a sending unit in the fuel tank.
The fuel gage indicates the quantity of fuel in the tank only when the ignition switch is turned to ON or ACC.
When the ignition is turned to LOCK or START, the pointer may come to rest at any position.
Temperature Gage
The temperature gage consists of an instrument cluster gage connected to a temperature sensor that is in contact
with the circulating engine coolant.
The temperature gage indicates the temperature of the coolant. Prolonged driving or idling in very hot weather
may cause the pointer to move beyond the center of the gage. The engine is overheating if the pointer moves
into the red zone at the upper limit of the gage.
Instrument Cluster Indicator Lamps
The instrument cluster contains indicator lamps that indicate the function of certain systems or the existence of
potential problems with the operation of the vehicle. The indicator lamps are replaceable. For replacement of
the indicator lamps contained in the instrument cluster, refer to Bulb Usage Specifications
and Instrument
Cluster Lamp Replacement .
Chime Module
The chime module is located above the instrument panel fuse block and will sound in order to bring attention to
one or more of the following conditions:
The lamps are ON, the door is ajar, and the ignition switch is not in ACC, ON, or START.
The seat belt is unbuckled when the ignition switch is in ON or START.
The door is open when the ignition switch is in ON or START.
The key is left in the ignition switch when the ignition is in LOCK and the door is open.
