Checking Coolant
The engine coolant surge tank is located in the rear
of the engine compartment on the driver’s side of
the vehicle. SeeEngine Compartment Overview on
page 258for more information on location.
{CAUTION:
Turning the surge tank pressure cap when
the engine and radiator are hot can allow
steam and scalding liquids to blow out
and burn you badly. Never turn the surge
tank pressure cap — even a little — when
the engine and radiator are hot.
To check the engine coolant, the vehicle must be
on a level surface. When your engine is cold,
the coolant level should be between the
Maximum (A) and Minimum (B) marks on the
coolant surge tank. The level rises at engine
operation temperature and drops again when the
engine cools down.
270

{CAUTION:
An electric engine cooling fan under the
hood can start up even when the engine
is not running and can injure you. Keep
hands, clothing, and tools away from any
underhood electric fan.
If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
Make sure that the air conditioning is turned off.
The coolant level should be between the Minimum
and Maximum marks on the coolant surge tank
when the engine is cool. If it is not, you may have
a leak at the pressure cap or in the radiator
hoses, heater hoses, radiator, water pump, or
somewhere else in the cooling system.
{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 268for more information.
If no coolant is visible in the surge tank, add
coolant as follows:
{CAUTION:
Steam and scalding liquids from a hot
cooling system can blow out and burn
you badly. They are under pressure, and if
you turn the coolant surge tank pressure
cap — even a little — they can come out at
high speed. Never turn the cap when the
cooling system, including the coolant
surge tank pressure cap, is hot. Wait for
the cooling system and coolant surge
tank pressure cap to cool if you ever have
to turn the pressure cap.
275

3. Fill the coolant surge tank with the proper
mixture to the Maximum mark on the
coolant surge tank. Wait about five minutes,
then check to see if the level is below the
mark. If the level is below the Maximum mark,
add additional coolant to bring the level up
to the mark. Repeat this procedure until
the level remains constant at the Maximum
mark for at least five minutes.4. With the coolant surge tank pressure cap off,
start the engine and let it run until you can
feel the upper radiator hose getting hot.
Watch out for the engine cooling fan.
By this time, the coolant level inside the
coolant surge tank may be lower. If the level
is lower than the Maximum mark, add
more of the proper mixture to the coolant
surge tank until the level reaches the mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
See your dealer, if necessary.

Power Steering Fluid
When to Check Power Steering Fluid
The power steering fluid reservoir is located toward
the front of the engine compartment on the
driver’s side of the vehicle. SeeEngine
Compartment Overview on page 258for reservoir
location.
It is not necessary to regularly check power
steering fluid unless you suspect there is a leak in
the system or you hear an unusual noise.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
How to Check Power Steering Fluid
Turn the key off and let the engine compartment
cool down. Then check the fluid level.The level should be between the MIN (B) and
MAX (A) marks on the reservoir. If the level
is below the MIN (B) mark, add the power steering
fluid to the appropriate level. Replace the cap
and completely tighten it.
What to Use
To determine what kind of fluid to use, see
Part D: Recommended Fluids and Lubricants on
page 382. Always use the proper fluid. Failure
to use the proper fluid can cause leaks and
damage hoses and seals.
279

CAUTION: (Continued)
But if a battery has ller caps, be sure
the right amount of uid is there. If it is low,
add water to take care of that rst. If you
don’t, explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.
{CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.5. Check that the jumper cables do not have
loose or missing insulation. If they do, you
could get a shock. The vehicles could
be damaged too.
Before you connect the cables, here are some
things you should know. Positive (+) will go
to positive (+) or to a remote positive (+)
terminal if the vehicle has one. Negative (−)
will go to a heavy, unpainted metal engine part
or to a remote negative (−) terminal if the
vehicle has one.
Do not connect positive (+) to negative (−)or
you will get a short that would damage
the battery and maybe other parts too. And do
not connect the negative (−) cable to the
negative (−) terminal on the dead battery
because this can cause sparks.

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level
and change as recommended.
Have you purchased the GM Protection Plan? The
Plan supplements your new vehicle warranties.
See your Warranty and Owner Assistance booklet
or your dealer for details.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended fluids and lubricants as prescribed
in this manual are necessary to keep your
vehicle in good working condition. Any damage
caused by failure to follow scheduled maintenance
may not be covered by warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep
your vehicle in good working condition, but also
helps the environment. Improper vehicle
maintenance can even affect the quality of the air
we breathe. Improper fluid levels or the wrong
tire inflation can increase the level of emissions
from your vehicle. To help protect our environment,
and to keep your vehicle in good condition, be
sure to maintain your vehicle properly.
How This Section is Organized
This maintenance schedule is divided into
five parts:
“Part A: Scheduled Maintenance Services”
explains what to have done and how often. Some
of these services can be complex, so unless
you are technically qualified and have the
necessary equipment, you should let your
GM dealer’s service department do these jobs.
Your GM dealer has GM-trained and supported
service people that will perform the work using
genuine GM parts.
356

Short Trip/City Scheduled
Maintenance
The services shown in this schedule up to
100,000 miles (166 000 km) should be repeated
after 100,000 miles (166 000 km) at the same
intervals for the life of this vehicle. The services
shown at 150,000 miles (240 000 km) should be
repeated at the same interval after 150,000 miles
(240 000 km) for the life of this vehicle.
SeePart B: Owner Checks and Services on
page 374andPart C: Periodic Maintenance
Inspections on page 380.
Footnotes
†The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that
the failure to perform this maintenance item will not
nullify the emission warranty or limit recall liability
prior to the completion of the vehicle’s useful life.
We, however, urge that all recommended
maintenance services be performed at the indicated
intervals and the maintenance be recorded.
+A good time to check your brakes is during
tire rotation. See Brake System Inspection
on page 381.
