Service
For service and parts needs, visit your dealer/retailer.
You will receive genuine GM parts and GM-trained and
supported service people.
Genuine GM parts have one of these marks:
Accessories and Modications
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 certied parts, including
control module modications, 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. When you go to your GM dealer/retailer
and ask for GM Accessories, you will know that
GM-trained and supported service technicians will
perform the work using genuine GM Accessories.

Vehicle on page 1-79.

The fuel cap is located on
the driver side of the
vehicle.
Open the door to access the fuel cap. To remove the
fuel cap, turn it slowly counterclockwise. While refueling,
let the fuel cap hang by the tether, if it has one. If the
vehicle has E85 fuel capability, the fuel cap will be
yellow and state that E85 or gasoline can be used.
SeeFuel E85 (85% Ethanol) on page 5-7.
{CAUTION:
Fuel can spray out on you if you open the fuel cap
too quickly. If you spill fuel and then something
ignites it, you could be badly burned. This spray
can happen if the tank is nearly full, and is more
likely in hot weather. Open the fuel cap slowly and
wait for any hiss noise to stop. Then unscrew the
cap all the way.
Be careful not to spill fuel. Do not top off or overll the
tank and wait a few seconds after you have nished
pumping before removing the nozzle. Clean fuel
from painted surfaces as soon as possible. See
Washing Your Vehicle on page 5-105.
When replacing the fuel cap, turn it clockwise until it
clicks. Make sure the cap is fully installed. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. This would allow fuel
to evaporate into the atmosphere. SeeMalfunction
Indicator Lamp on page 3-40.

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel ll. 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 5-14for
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.
5-15

3. Install the dipstick by pushing it back in all the way,
wait three seconds, and then pull it back out again.
4. Check both sides of the dipstick, and read the lower
level. Repeat the check procedure to verify the
reading.
5. If the uid level is below the COLD check band,
add only enough uid as necessary to bring the
level into the COLD band. It does not take
much uid, generally less than one pint (0.5L).
Do not overll.
6. Perform a hot check at the rst opportunity after
the transmission reaches a normal operating
temperature between 160°F to 200°F (71°C to 93°C).
7. If the uid level is in the acceptable range, push the
dipstick back in all the way, then ip the handle
down to lock the dipstick in place.Hot Check Procedure
Use this procedure to check the transmission uid level
when the transmission uid temperature is between
160°F and 200°F (71°C and 93°C).
The hot check is the most accurate method to check the
uid level. The hot check should be performed at the rst
opportunity in order to verify the cold check. The uid
level rises as uid temperature increases, so it is
important to ensure the transmission temperature is
within range.
1. Locate the transmission
dipstick at the
rear of the engine
compartment, on the
passenger side of
the vehicle.
SeeEngine Compartment Overview on page 5-14
for more information.
2. Flip the handle up, and then pull out the dipstick
and wipe it with a clean rag or paper towel.
3. Install the dipstick by pushing it back in all the way,
wait three seconds, and then pull it back out again.
4. Check both sides of the dipstick, and read the lower
level. Repeat the check procedure to verify the
reading.
5-25

5. Safe operating level is within the HOT cross hatch
band on the dipstick. If the uid level is not within the
HOT band, and the transmission temperature is
between 160°F and 200°F (71°C and 93°C), add or
drain uid as necessary to bring the level into the
HOT band. If the uid level is low, add only enough
uid to bring the level into the HOT band. It does not
take much uid, generally less than one pint (0.5L).
Do not overll.
6. If the uid level is in the acceptable range, push the
dipstick back in all the way, then ip the handle
down to lock the dipstick in place.
Consistency of Readings
Always check the uid level at least twice using the
procedures described. Consistency is important to
maintaining proper uid level. If uid is added, it may take
15 minutes or longer to obtain an accurate reading
because of residual uid draining down the dipstick tube.
If inconsistent readings persist, check the transmission
breather to be sure it is clean and not clogged. If readings
are still inconsistent, contact your dealer/retailer.

{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.
1. Locate the coolant
surge tank pressure
cap that has this label.
2. You can remove the coolant surge tank pressure
cap when the cooling system, including the coolant
surge tank pressure cap and upper radiator hose,
are no longer hot. Turn the pressure cap slowly
counterclockwise about one full turn.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
3. Then keep turning the pressure cap slowly, and
remove it.4. Fill the coolant surge tank with the proper mixture,
to the FULL COLD mark.

Headlamps
To replace a headlamp bulb:
1. Open the hood. SeeHood Release on page 5-12.
2. Locate the affected headlamp on the inner front
portion of the hood.
3. Turn the bulb socket
counterclockwise and
pull it out of the
headlamp assembly.4. Unplug the electrical
connector.
5. Pull the old bulb straight out of the bulb socket.
6. Push the new bulb socket into the headlamp
assembly aligning the bulb socket with the
headlamp assembly. Do not to touch the bulb with
your ngers or hands.
7. Turn the bulb socket retainer clockwise to lock it
into place.
8. Plug in the electrical connector.
