Trailer Brakes
Does the trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer
brakes so they are installed,
adjusted and maintained properly.
Because the vehicle has anti-lock
brakes, do not tap into the vehicle’s
brake system. If you do, both brake
systems will not work well, or at all.
Trailer Wiring Harness
All of the electrical circuits required
for the trailer lighting system can be
accessed at the driver’s side rear
lamp connector. This connector is
located under the carpet at the rear
corner of the cargo compartment.

Notice:Do not add anything
electrical to the vehicle unless you
check with your dealer/retailer
rst. Some electrical equipment
can damage the vehicle and the
damage would not be covered by
the vehicle’s warranty. Some
add-on electrical equipment can
keep other components from
working as they should. Add-on equipment can drain the
vehicle battery, even if the vehicle is
not operating.
The vehicle has an airbag system.

California Perchlorate
Materials Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt pretensioners,
and lithium batteries contained
in remote keyless transmitters,
may contain perchlorate materials.
Special handling may be necessary.
For additional information, see
www.dtsc.ca.gov/hazardouswaste/
perchlorate.
Accessories and
Modi cations
When non-dealer/non-retailer
accessories are added to the vehicle,
they can affect vehicle performance
and safety, including such things
as airbags, braking, stability, ride
and handling, emissions systems,
aerodynamics, durability, and
electronic systems like antilock
brakes, traction control, and stability
control. Some of these accessories
could even cause malfunction or
damage not covered by the vehicle
warranty.Damage to vehicle components
resulting from the installation or use
of non-GM certified parts, including
control module modifications, are
not covered under the terms of the
vehicle warranty and may affect
remaining warranty coverage for
affected parts.
GM Accessories are designed
to complement and function with
other systems on the vehicle.
Your GM dealer/retailer can
accessorize the vehicle using
genuine GM Accessories.

Checking Engine Oil
It is a good idea to check the
engine oil level at each fuel fill.
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. See Engine
Compartment Overview on page 9-6
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 this is not done,
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.
Vehicle Care 9-9
Checking the Fluid Level
Prepare your vehicle as follows:
1. Park your vehicle on a levelplace. Keep the engine running.
2. With the parking brake applied, place the shift lever in P (Park).
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 P (Park).
4. Let the engine run at idle for three to five minutes. Then, without shutting off the
engine, follow these steps:
The automatic transmission
dipstick has an orange handle
and is located near the front of the
engine compartment. See
Engine
Compartment Overview on page 9-6
for more information on location.
1. Release the tab and 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
fluid level must be between the
two dimples in the hot range.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way;
then press the tab down to lock
the dipstick in place. 1.8L shown
Vehicle Care 9-13
How to Add Automatic
Transmission Fluid
Refer to the Maintenance
Schedule to determine what
kind of transmission fluid to use.
Recommended Fluids and
Lubricants on page 10-15.
If the fluid level is low, add only
enough of the proper fluid to bring
the level into the area between
dimples on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the dipstick
hole to bring it to the proper level.
It does not take much fluid,
generally less than one pint
(0.5 L). Do not overfill. Notice:
Too much or too
little uid can damage your
transmission. Too much can mean
that some of the uid could come
out and fall on hot engine parts or
exhaust system parts, starting a
re. Too little uid could cause the
transmission to overheat. Be sure
to get an accurate reading if you
check your transmission uid.
3. After adding fluid, recheck the fluid level as described under
“How to Check Automatic
Transmission Fluid,” earlier
in this section.
4. When the correct fluid level is obtained, push the dipstick
back in all the way; then press
the tab down to lock the dipstick
in place.
Manual Transmission
Fluid
When to Check
A good time to have your manual
transmission fluid level checked
is when the engine oil is changed.
However, the fluid in your manual
transmission does not require
changing.
How to Check
This operation can be difficult, you
may choose to have this done
at your dealer/retailer service
department.
If you do it yourself, be sure to
follow all the instructions here, or
you could get a false reading.

How to Add Coolant to the
Radiator
When the coolant in the coolant
recovery tank is at the FULL mark,
start the vehicle.
If the overheat warning continues,
there is one more thing that can
be done. Add the proper coolant
mixture directly to the radiator but
be sure the cooling system is
cool before you do it.
{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
surge tank pressure cap — even a
little — they can come out at high
speed. Never turn the cap when
the cooling system, including the
surge tank pressure cap, is hot.
Wait for the cooling system and(Continued)
CAUTION (Continued)
surge tank pressure cap to cool
if you ever have to turn the
pressure cap.
{CAUTION
Turning the radiator pressure cap
when the engine and radiator are
hot can allow steam and scalding
liquids to blow out and burn you
badly. With the coolant recovery
tank, you will almost never have
to add coolant at the radiator.
Never turn the radiator pressure
cap — even a little — when the
engine and radiator are hot.
1. Remove the pressure cap when the cooling system, including the
pressure cap and upper radiator
hose, is no longer hot. Turn
the pressure cap slowly
counterclockwise until it first
stops. Do not press down while
turning the pressure cap. If you hear a hiss, wait for that to
stop. A hiss means there is
still some pressure left.
2. Keep turning the pressure cap, but now push down while turning.
Remove the pressure cap.
3. Fill the radiator with the proper coolant mixture, up to the base
of the filler neck. For more
information about the proper
coolant mixture look earlier in
this section.
4. Then fill the coolant recovery tank to the FULL mark.
