Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 410
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil
several minutes to drain back into the oil pan.
If you do not do this, the oil dipstick might
not show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.

How to Check Automatic Transaxle
Fluid
Because this operation can be a little difficult, you
may choose to have this done at the dealership
service department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading
on the dipstick.
Notice:Too much or too little uid can damage
the transaxle. Too much can mean that some of
the uid could come out and fall on hot engine
or exhaust system parts, starting a re. Too
little uid could cause the transaxle to overheat.
Be sure to get an accurate reading if you check
the transaxle uid.
Wait at least 30 minutes before checking the
transaxle uid level if you have been driving:
When outside temperatures are above
90°F (32°C).
At high speed for quite a while.
In heavy traffic — especially in hot weather.
While pulling a trailer.To get the right reading, the uid should be at
normal operating temperature, which is 180°F to
200°F (82°C to 93°C).
Get the vehicle warmed up by driving about
15 miles (24 km) when outside temperatures are
above 50°F (10°C). If it is colder than 50°F (10°C),
you may have to drive longer.
Checking the Fluid Level
Prepare your vehicle as follows:
1. Park your 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 range, pausing
for about three seconds in each range.
Then, position the shift lever in PARK (P).
4. Let the engine run at idle for three to
ve minutes.
418

Then, without shutting off the engine, follow these
steps:
1. Pull out the dipstick and wipe it with a clean
rag or paper towel.
The automatic transaxle dipstick is located
toward the back of the engine compartment,
near the brake master cylinder reservoir.
The dipstick handle is a red loop. SeeEngine
Compartment Overview on page 410for
more information on location.
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
cross-hatched 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 518.
If the uid level is low, add only enough of the
proper uid to bring the level into the
cross-hatched 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 518.
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.

Brakes
Brake Fluid
Your brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 410for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake system. If it is, you should have your
brake system xed, since a leak means that
sooner or later your brakes will not work well, or
will not work at all.So, it is not a good idea to top off your brake uid.
Adding brake uid will not correct a leak. If you
add uid when your linings are worn, then you will
have too much uid when you get new brake
linings. You should add or remove brake uid, as
necessary, only when work is done on the
brake hydraulic system.
{CAUTION:
If you have too much brake uid, it can
spill on the engine. The uid will burn if
the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake hydraulic
system.
When your brake uid falls to a low level, your
brake warning light will come on. SeeBrake
System Warning Light on page 214.
434

What to Add
When you do need brake uid, use only DOT-3
brake uid. Use new brake uid from a sealed
container only. SeeRecommended Fluids
and Lubricants on page 518.
Always clean the brake uid reservoir cap and the
area around the cap before removing it. This
will help keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in your brake
system, your brakes may not work well, or
they may not even work at all. This could
cause a crash. Always use the proper
brake uid.Notice:
Using the wrong uid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in your brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 491.
435

Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake’s holding ability:
With the engine running and transaxle in
NEUTRAL (N), slowly remove foot pressure
from the regular brake pedal. Do this until the
vehicle is held by the parking brake only.
To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to
PARK (P). Then release the parking brake
followed by the regular brake.
Contact your GM Goodwrench
®dealer if service is
required.
Underbody Flushing Service
At least every spring, use plain water to ush any
corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud and
other debris can collect.
