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.
1. Turn the pressure cap slowly counterclockwise. If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
2. Then keep turning the cap and remove it.
3. Fill the coolant surge tank with the proper
mixture to the FULL
COLD mark on the
side of the coolant
surge tank. 4. With the coolant surge tank 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, add
more of the proper mixture to the coolant surge
tank until the level reaches the FULL COLD mark
on the side of the coolant surge tank.
5. Then replace the cap. Be sure the cap is hand‐tight and fully seated.
If coolant is needed, add the proper DEX-COOL
®
coolant mixture at the coolant recovery tank.
Notice: If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Coolant (3.9L Engine)
The cooling system in the vehicle is filled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for five years or 150,000 miles
(240 000 km), whichever occurs first.
The following explains the cooling system and how
to check and add coolant when it is low. If there is
a problem with engine overheating, see Engine
Overheating on page 6‑35.

How to Add Coolant to the Radiator
{WARNING:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
{WARNING:
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 surge
tank pressure cap to cool if you ever have to turn
the pressure cap. If coolant is needed, add the proper mixture directly to
the radiator, but be sure the cooling system is cool
before this is done.
1. You can 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.
2. If you hear a hiss, wait for that to stop. A hiss means that there is still some pressure left. Keep
turning the pressure cap and remove it.
3. Fill the cooling system with the proper DEX-COOL coolant mixture, up to the base of the filler neck.
See Engine Coolant (4.6L Engine)
on page 6‑28orEngine Coolant (3.9L Engine) on page 6‑31.
4. Then fill the coolant recovery tank to the COLD FILL line.

Brake Adjustment
Every time the brakes are applied, with or without the
vehicle moving, the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. The vehicle
was designed and tested with top-quality brake parts.
When parts of the braking system are replaced—for
example, when the brake linings wear down and new
ones are installed —be sure to get new approved
replacement parts. If this is not done, the brakes might
not work properly. For example, if someone puts in
brake linings that are wrong for the vehicle, the balance
between the front and rear brakes can change —for the
worse. The braking performance expected can change
in many other ways if the wrong replacement brake
parts are installed.
Battery
Refer to the replacement number on the original battery
label when a new battery is needed.
{DANGER:
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the State of California to cause cancer
and reproductive harm. Wash hands after
handling.
The battery is under the rear seat cushion. To access
the battery, see “Removing the Rear Seat Cushion”
under Rear Underseat Fuse Block
on page 6‑110.
Access to the battery is not necessary to jump start the
vehicle. See Jump Starting on page 6‑44.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
The identification code needs to be matched to a new
tire/wheel position after rotating the vehicle’s tires or
replacing one or more of the TPMS sensors. Also, the
TPMS sensor matching process should be performed
after replacing a spare tire with a road tire containing
the TPMS sensor. The malfunction light and the DIC
message should go off at the next ignition cycle. The
sensors are matched to the tire/wheel positions, using a
TPMS relearn tool, in the following order: driver side
front tire, passenger side front tire, passenger side rear
tire, and driver side rear. See your dealer for service or
to purchase a relearn tool.
There are two minutes to match the first tire/wheel
position, and five minutes overall to match all four tire/
wheel positions. If it takes longer, the matching process
stops and must be restarted.
The TPMS sensor matching process is:1. Set the parking brake.
2. Turn the ignition to ON/RUN with the engine off.
3. Press the Remote Keyless Entry (RKE) transmitter's lock and unlock buttons at the same
time for approximately five seconds. The horn
sounds twice to signal the receiver is in relearn
mode and TIRE LEARNING ACTIVE message
displays on the DIC screen. 4. Start with the driver side front tire.
5. Place the relearn tool against the tire sidewall,
near the valve stem. Then press the button to
activate the TPMS sensor. A horn chirp confirms
that the sensor identification code has been
matched to this tire and wheel position.
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in Step 5. The horn sounds two times to
indicate the sensor identification code has been
matched to the driver side rear tire, and the TPMS
sensor matching process is no longer active. The
TIRE LEARNING ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading
Information label.

{WARNING:
Using bias-ply tires on the vehicle may
cause the wheel rim flanges to develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly and cause
a crash. Use only radial-ply tires with the
wheels on the vehicle.
If you must replace your vehicle's tires with those
that do not have a TPC Spec number, make sure
they are the same size, load range, speed rating,
and construction type (radial and bias‐belted tires)
as your vehicle's original tires.
Vehicles that have a tire pressure monitoring
system could give an inaccurate low‐pressure
warning if non‐TPC Spec rated tires are installed
on your vehicle. Non‐TPC Spec rated tires may
give a low‐pressure warning that is higher or lower
than the proper warning level you would get with
TPC Spec rated tires. See Tire Pressure Monitor
System
on page 6‑65. Your vehicle's original equipment tires are listed
on the Tire and Loading Information Label. See
Loading the Vehicle
on page 5‑18, for more
information about the Tire and Loading
Information Label and its location on your vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability, and
resistance to rollover. Additionally, if your vehicle has
electronic systems such as, antilock brakes, traction
control, and electronic stability control, the performance
of these systems can be affected.
{WARNING:
If different sized wheels are used, there may not
be an acceptable level of performance and safety
if tires not recommended for those wheels are
selected. This increases the chance of a crash
and serious injury. Only use GM specific wheel
and tire systems developed for the vehicle, and
have them properly installed by a GM certified
technician.

Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inflate a
Punctured Tire
Follow the directions closely for correct sealant usage.
When using the tire sealant and compressor kit
during cold temperatures, warm the kit in a heated
environment for five minutes. This will help to inflate the
tire faster.
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on the hazard
warning flashers. SeeHazard Warning Flashers
on
page 4‑3. See
If a Tire Goes Flat
on page 6‑78for other
important safety warnings.
Do not remove any objects that have penetrated
the tire.
Always do a safety check first. See If a Tire Goes Flat
on page 6‑78. Do not remove any objects that have
penetrated the tire.
1. Remove the tire sealant and compressor kit from its storage location. See Tire Sealant and
Compressor Kit Storage on page 6‑87.
2. Unwrap the sealant/air hose (F) and the power plug (G).
3. Place the kit on the ground.
Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve stem. Turn it clockwise until it is tight.
6. Plug the power plug (G) into the accessory power outlet in the vehicle. Unplug all items from other
accessory power outlets. See Accessory Power
Outlet(s) on page 4‑15.
If the vehicle has an accessory power outlet, do
not use the cigarette lighter.
