Checking the Fluid Level
Prepare the vehicle as follows:
1. Park the vehicle on a level place. Keep the
engine running.
2. With the parking brake applied, place the shift
lever in PARK (P).
3. With your foot on the brake pedal, move the
shift lever through each gear, pausing for
about three seconds in each one. Then,
position the shift lever in PARK (P).
4. Let the engine run at idle for three to
ve minutes.
Then, without shutting off the engine, follow
these steps:
The transaxle uid
dipstick handle has this
symbol on it, and is
located near the rear of
the engine compartment.SeeEngine Compartment Overview on page 354
for more information on location.
1. Pull out the dipstick and wipe it with a clean
rag or paper towel.
2. Push it back in all the way, wait three seconds
and then pull it back out again.
3. Check both sides of the dipstick, and read the
lower level. The uid level must be in the
crosshatched area.
4. If the uid level is in the acceptable range,
push the dipstick back in all the way.

How to Add Automatic Transaxle Fluid
Refer to the Maintenance Schedule to determine
what kind of transaxle uid to use. See
Recommended Fluids and Lubricants on page 468.
If the uid level is low, add only enough of the
proper uid to bring the level into the crosshatched
area on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough uid at
the dipstick hole to bring it to the proper level.
It does not take much uid, generally less
than one pint (0.5 L). Do not overll.
Notice:Use of the incorrect automatic
transaxle uid may damage your vehicle, and
the damages may not be covered by your
warranty. Always use the automatic transaxle
uid listed inRecommended Fluids and
Lubricants on page 468.
3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transaxle Fluid,” earlier in this section.
4. When the correct uid level is obtained, push
the dipstick back in all the way.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.
The following explains the cooling system and
how to add coolant when it is low. If there is
a problem with engine overheating, seeEngine
Overheating on page 371.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®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.
368

If you have to add coolant more than four times a
year, have your dealer/retailer check the cooling
system.
Notice:If you use extra inhibitors and/or
additives in your vehicle’s cooling system, you
could damage your vehicle. Use only the
proper mixture of the engine coolant listed in
this manual for the cooling system. See
Recommended Fluids and Lubricants on
page 468for more information.Checking Coolant
The engine coolant surge tank is located in the
rear of the engine compartment. SeeEngine
Compartment Overview on page 354for more
information on location.
370

The coolant level should be at or above the FULL
COLD mark on the front of the coolant surge
tank. 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 fans
are running. If the engine is overheating, both fans
should be running. If they are not, your vehicle
needs service.Notice:Engine damage from running your
engine without coolant is not covered by your
warranty.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core, or
radiator corrosion. In addition, the engine
coolant could require changing sooner, at
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
375

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 at or above
the FULL COLD mark, add a 50/50 mixture of
clean, drinkable water and DEX-COOL
®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 368for 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.
376

2. Then keep turning the pressure cap slowly,
and remove it.
3. Fill the coolant surge tank with the proper
mixture, to the FULL COLD mark on the
front of the surge tank. Wait about
ve minutes, then check to see if the level
is below the FULL COLD mark. If the level is
below the FULL COLD mark, add additional
coolant to bring the level up to the mark.
Repeat this procedure until the level remains
constant at the FULL COLD mark for at
least ve 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 fans.
By this time, the coolant level inside the
coolant surge tank may be lower. If the level
is lower than the FULL COLD mark, add
more of the proper mixture to the coolant
surge tank until the level reaches the
FULL COLD 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
SeeEngine
Compartment Overview
on page 354for
reservoir location.
When to Check Power Steering Fluid
Power steering uid is used in all vehicles with
V6 engines. Vehicles with the 4-cylinder engine
have electric power steering and do not use power
steering uid.
It is not necessary to regularly check power
steering uid unless a leak is suspected in the
system, or an unusual noise is heard. A uid loss
in this system could indicate a problem. Have
the system inspected and repaired.
How to Check Power Steering Fluid
To check the power steering uid, do the following:
1. Turn the key off and let the engine
compartment cool down.
2. Wipe the cap and the top of the reservoir
clean.
3. Unscrew the cap and wipe the dipstick with
a clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the
uid level on the dipstick
The uid level should be within the crosshatched
area on the dipstick.
If the uid is at or below the ADD mark on the
dipstick, add just enough uid to bring the
level within the crosshatched area.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 468.
Always use the proper uid. Failure to use the
proper uid can cause leaks and damage hoses
and seals.
379

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.
{CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.6. Connect the red positive (+) cable to the
positive (+) terminal of the dead battery.
7. Do not let the other end touch metal. Connect
it to the positive (+) terminal of the good
battery. Use a remote positive (+) terminal if
the vehicle has one.

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
Notice:Maintenance intervals, checks,
inspections, replacement parts, and
recommended uids 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 might 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. All recommended
maintenance is important. Improper vehicle
maintenance can even affect the quality of the
air we breathe. Improper uid levels or the wrong
tire ination 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.
Using the Maintenance Schedule
We at General Motors want to help you keep
your vehicle in good working condition. But we do
not know exactly how you will drive it. You may
drive very short distances only a few times a week.
Or you may drive long distances all the time in
very hot, dusty weather. You may use your
vehicle in making deliveries. Or you may drive it
to work, to do errands, or in many other ways.
