Uplevel Display Shown, BaseModel Similar
The display on the instrument panel
cluster will show which gear the
vehicle is in. The number indicates
the requested gear range when
moving the shift lever forward or
rearward. The transmission will only allow you
to shift into gears appropriate for the
vehicle speed and engine
Revolutions Per Minute (RPM). The
transmission will not automatically
shift to the next lower gear if the
engine RPM is too high, nor to the
next higher gear when the maximum
engine RPM is reached.
While in the DSC mode, the
transmission will automatically
downshift when the vehicle comes
to a stop. This will allow for more
power during take-off.
When accelerating the vehicle from
a stop in snowy and icy conditions,
you may want to shift into second
gear. A higher gear allows you to
gain more traction on slippery
surfaces.
Drive Systems
All-Wheel Drive
With this feature, engine power is
always sent to all four wheels. It is
fully automatic, and adjusts itself as
needed for road conditions.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and disables AWD. To restore
AWD operation and prevent
excessive wear on system, replace
the compact spare with a full-size
tire as soon as possible. See
Compact Spare Tire
on page 9‑74for more information.

9-20 Vehicle Care
3. Fill the coolant surge tank withthe proper mixture to the mark
pointed to on the front of the
coolant surge tank.
4. With the coolant surge tank cap off, start the engine and let it run
until the upper radiator hose
starts getting hot. Watch out for
the engine cooling fan(s). 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 mark pointed to on
the front of the coolant
surge tank.
5. Replace the cap. Be sure the cap is hand–tight and full
seated.
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.
If coolant is needed, add the proper
DEX-COOL®coolant mixture at the
coolant recovery tank.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is a coolant temperature gage
and a warning light on the
instrument panel cluster that
indicate an overheated engine
condition. See Engine Coolant
Temperature Gage
on page 4‑15for more information. You may decide not to lift the hood
when this warning appears, but
instead get service help right away.
See
Roadside Assistance Program
(US, Can) on page 12‑6.
If you do decide to lift the hood ,
make sure the vehicle is parked on
a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fan(s)
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice: Engine damage from
running the engine without
coolant is not covered by the
warranty.

The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch toON/RUN with the engine off.
3. Use the MENU button to select the Vehicle Information Menu in
the Driver Information
Center (DIC).
4. Use the thumbwheel to scroll to the Tire Pressure Menu Item
screen.
5. Press the SET/CLR button to begin the sensor matching
process.
A message asking if you are
sure you want to begin this
process should appear. 6. Press the SET/CLR button again
to confirm the selection.
The horn sounds twice to signal
the receiver is in relearn mode
and the TIRE LEARNING
ACTIVE message displays on
the DIC screen.
7. Start with the driver side front tire.
8. Remove the valve cap from the valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire's air pressure
for five seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to
30 seconds to sound, confirms
that the sensor identification
code has been matched to this
tire and wheel position.
9. Proceed to the passenger side front tire, and repeat the
procedure in Step 8. 10. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 8.
11. Proceed to the driver side rear tire, and repeat the procedure
in Step 8. 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.
12. Turn the ignition switch to LOCK/OFF.
13. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.
14. Put the valve caps back on the valve stems.

Customer Information 12-11
any vehicle failure related to such
parts are not covered by that
warranty.
Repair Facility
We recommend that you choose a
collision repair facility that meets
your needs before you ever need
collision repairs. Your dealer/retailer
may have a collision repair center
with GM-trained technicians and
state of the art equipment, or be
able to recommend a collision repair
center that has GM-trained
technicians and comparable
equipment.
Insuring Your Vehicle
Protect your investment in your GM
vehicle with comprehensive and
collision insurance coverage. There
are significant differences in the
quality of coverage afforded by
various insurance policy terms.
Many insurance policies provide
reduced protection to your GM
vehicle by limiting compensation for
damage repairs by usingaftermarket collision parts. Some
insurance companies will not
specify aftermarket collision parts.
When purchasing insurance, we
recommend that you assure your
vehicle will be repaired with GM
original equipment collision parts.
If such insurance coverage is not
available from your current
insurance carrier, consider switching
to another insurance carrier.
If your vehicle is leased, the leasing
company may require you to have
insurance that assures repairs with
Genuine GM Original Equipment
Manufacturer (OEM) parts or
Genuine Manufacturer replacement
parts. Read your lease carefully, as
you may be charged at the end of
your lease for poor quality repairs.
If a Crash Occurs
If there has been an injury, call
emergency services for help. Do not
leave the scene of a crash until all
matters have been taken care of.
Move the vehicle only if its position
puts you in danger, or you are
instructed to move it by a police
officer.
Give only the necessary information
to police and other parties involved
in the crash.
