Trailer Brakes
Because you have anti-lock brakes, do not try to tap
into your vehicle’s hydraulic brake system. If you
do, both brake systems will not work well, or at all. If
you tow more than 1,000 lbs (450 kg), use trailer brakes.
Be sure to follow the instructions that come with the
trailer or from the brake manufacturer.
Be sure to read and follow the instructions for the trailer
brakes so you will be able to install, adjust and
maintain them properly. Be sure to read and follow the
instructions for the trailer brakes so you will be able
to install, adjust and maintain them properly.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you will want to
get to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be
sure the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You will need more passing distance up ahead when you
are towing a trailer. And, because you are a good deal
longer, you will need to go much farther beyond the
passed vehicle before you can return to your lane.

To open the fuel door, press the fuel door release
button upward. The vehicle must be in PARK (P) or
NEUTRAL (N) and the valet lockout button must be
in OFF.
An alternate fuel door
release strap is located
inside the trunk on
the driver’s side of the
vehicle.
Pull the strap to release the fuel door.While refueling, hang the fuel cap by the tether from the
hook on the fuel door.
To remove the fuel cap, turn it slowly to the left
(counterclockwise). The fuel cap has a spring in it; if
you let go of the cap too soon, it will spring back to
the right.

{CAUTION:
If you spill fuel and then something ignites it,
you could be badly burned. Fuel can spray out
on you if you open the fuel cap too quickly. This
spray can happen if your 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 overfill your
tank, and wait a few seconds after you have finished
pumping before you remove the nozzle. Clean fuel from
painted surfaces as soon as possible. SeeCleaning
the Outside of Your Vehicle on page 5-90.
When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install the cap. 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 3-46.The CHECK GAS CAP message in the Driver
Information Center (DIC) will come on if the fuel cap is
not properly reinstalled.{CAUTION:
If a fire starts while you are refueling, do not
remove the nozzle. Shut off the flow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not fit properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp on
page 3-46.

If the CHECK OIL LEVEL message appears on the
instrument cluster, it means you need to check
your engine oil level right away. For more information,
see “CHECK OIL LEVEL” underDIC Warnings and
Messages on page 3-55.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your 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. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not show the actual level.
5-13

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.
When to Add Engine Oil
If the oil is at or below the cross-hatched area at the tip
of the dipstick, then you will need to add at least one
quart of oil. But you must use the right kind. This section
explains what kind of oil to use. For engine oil
crankcase capacity, seeCapacities and Specications
on page 5-104.
Notice:Do not add too much oil. If your engine has
so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, your engine could be damaged.SeeEngine Compartment
Overview on page 5-12for
the location of the
engine oil fill cap.
Turn the cap counterclockwise to remove it.
Be sure to add enough oil to put the level somewhere in
the proper operating range in the cross-hatched area.
Push the dipstick all the way back in when you are
through.
What Kind of Engine Oil to Use
Look for two things:
•GM6094M
Your vehicle’s engine requires oil meeting GM
Standard GM6094M. You should look for and use
only an oil that meets GM Standard GM6094M.

Then, without shutting off the engine, follow these steps:
The transaxle fluid cap is
located next to the radiator
hose and below the
engine air cleaner/filter
assembly in the engine
compartment on the
driver’s side of the vehicle.
SeeEngine Compartment
Overview on page 5-12
for more information
on location.
1. After removing the engine air cleaner/filter assembly
to reach the transaxle fluid cap, turn the cap
counterclockwise to remove. 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 in the
cross-hatched area.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way and turn the handle
clockwise. Reinstall the engine air cleaner/filter
assembly.
5-22

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. SeeRecommended Fluids
and Lubricants on page 6-12.
If the fluid level is low, add only enough of the proper
fluid 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 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:Use of automatic transaxle fluid labeled
other than DEXRON
®-III may damage your vehicle,
and the damages may not be covered by your
warranty. Always use DEXRON
®-III labeled automatic
transaxle fluid.
3. After adding fluid, recheck the fluid level as
described underHow to Check.
4. When the correct fluid level is obtained, push the
dipstick back in all the way and turn the handle
clockwise. Reinstall the engine air cleaner/filter
assembly.
How to Reset the Transaxle Fluid
Change Indicator
Once the transaxle fluid has been changed, the
transaxle fluid change indicator must be reset. Use the
following steps to reset the indicator:
1. Press the INFO button on the Driver Information
Center (DIC) until TRANS FLUID LIFE is displayed.
2. Press and hold the INFO RESET button until 100%
is displayed.
The indicator is now reset. The percentage of transaxle
fluid life remaining may be checked at any time by
pressing the INFO button several times until the TRANS
FLUID LIFE message appears.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add
only DEX-COOL
®extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-26.
5-23

1. Park the vehicle on a level surface. You can
remove the coolant surge tank pressure cap
when the cooling system, including the coolant
surge tank pressure cap and upper radiator hose, is
no longer hot. Turn the pressure cap slowly
counterclockwise (left) 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. Press down on the pressure cap and keep turning it
slowly. Remove the cap.3. Then fill the coolant surge tank with the proper
mixture, to or above the fill mark at the forward
edge of the surge tank.
