Rear Window Defogger
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger turns
off automatically after about
10 minutes. If turned on again, it
runs for about five minutes before
turning off. At higher speeds, the
rear window defogger may stay on
continuously.
For vehicles with heated outside
rearview mirrors, they turn on with
the rear window defogger and help
to clear fog or frost from the surface
of the mirror. See Heated Mirrors on
page 2‑15. Notice:
Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
may damage the rear window
defogger grid and affect your
radio's ability to pick up stations
clearly. The repairs would not be
covered by your warranty.
Sensors
The solar sensor located on top
of the instrument panel near the
windshield monitors the solar heat.
The climate control system uses
the sensor information to adjust
the temperature, fan speed,
recirculation, and air delivery
mode for best comfort.
If the sensor is covered, the dual
automatic climate control system
may not work properly.
Air Vents
Use the louvers located on the air
vents to change the direction of the
airflow.
To open a vent, move the
thumbwheel to | . To close the vent,
move the thumbwheel to
9.
Operation Tips
.Keep all outlets open whenever
possible for best system
performance.
.Keep the paths under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
.Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.

3. Then turn the steering wheel togo straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
.Steering or Cornering
Skid —too much speed or
steering in a curve causes tires
to slip and lose cornering force.
.Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible. If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the
accelerator pedal and quickly
steer the way you want the
vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs.
.Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other
material on the road. Learn to
recognize warning clues
—such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
.Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide. Remember: Antilock brakes help
avoid only the braking skid.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep‐standing or flowing water.
{WARNING
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.

9-34 Driving and Operating
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get tooclose to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch for the
EPB is on the center console. The
EPB can always be activated, even
if the ignition is off. To prevent
draining the battery, avoid repeated
cycles of the EPB system when the
engine is not running.
The system has a parking brake
status light and a parking brake
warning light. See
Electric Parking
Brake Light on page 5‑19. There are
also three parking brake related

9-42 Driving and Operating
Drive Mode Control
Drive Mode Control (DMC) analyzes
the driving style and the active state
of the vehicle and automatically
changes the settings within the
selected driving mode. When there
is a more noticeable change in
driving style or conditions, the
driving mode is changed to Sport
until the previous driving style
returns.
If Standard mode is selected and
sport driving is detected, several
settings of the Standard mode
change to sport settings. If sport
driving increases, DMC changes to
Sport mode.
If Tour mode is selected and sudden
braking or cornering is necessary,
DMC changes the suspension
settings to Sport mode to increase
vehicle stability.
When the driving characteristic or
the active state of the vehicle
returns to the previous style, DMC
changes the settings to the
preselected driving mode.
Cruise Control
With cruise control, the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
On vehicles with the Traction
Control System (TCS) or StabiliTrak,
the system may begin to limit wheel
spin while you are using cruise
control. If this happens, the cruise
control will automatically disengage.
SeeTraction Control System (TCS)
on page 9‑37 orStabiliTrak
®System
on page 9‑39.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
(Continued)
WARNING (Continued)
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
1(On/Off):Press to turn the
cruise control system on and off. An
indicator light will turn on or off in

be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the ignition to ON/RUN withthe engine off. 2. Press the DIC MENU button on
the turn signal lever to enter the
Vehicle Information Menu. Use
the thumbwheel to scroll through
the menu items until you reach
REMAINING OIL LIFE.
3. Press the SET/CLR button to reset the oil life at 100%.
4. Turn the ignition to LOCK/OFF.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off and the REMAINING
OIL LIFE 100% message is
displayed.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.

Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, you should
have this done at your dealer.
Contact your dealer for additional
information. The procedure can be
found in the service manual. To
purchase a service manual, see
Service Publications Ordering
Information on page 13‑16.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule on page 11‑3, and be sure

All-Season Tires
This vehicle may come with
all-season tires. These tires are
designed to provide good overall
performance on most road surfaces
and weather conditions. Original
equipment tires designed to GM's
specific tire performance criteria
have a TPC specification code
molded onto the sidewall. Original
equipment all-season tires can be
identified by the last two characters
of this TPC code, which will
be“MS.”
Consider installing winter tires on
the vehicle if frequent driving on
snow or ice covered roads is
expected. All-season tires provide
adequate performance for most
winter driving conditions, but they
may not offer the same level of
traction or performance as winter
tires on snow or ice covered roads.
See Winter Tires on page 10‑45.
Winter Tires
Consider installing winter tires on
the vehicle if frequent driving on
snow or ice covered roads is
expected. All season tires provide
good overall performance on most
surfaces, but they may not offer
the traction or the same level of
performance as winter tires on snow
or ice covered roads.
Winter tires, in general, are
designed for increased traction on
snow and ice covered roads. With
winter tires, there may be decreased
dry road traction, increased road
noise, and shorter tread life. After
changing to winter tires, be alert for
changes in vehicle handling and
braking. See your dealer for details
regarding winter tire availability and
proper tire selection. Also, see
Buying New Tires on page 10‑60.
If using snow tires:
.Use tires of the same brand and
tread type on all four wheel
positions.
.Use only radial ply tires of the
same size, load range, and
speed rating as the original
equipment tires.
Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.

Use this rotation pattern when
rotating the tires.
Do not include the compact
spare tire in the tire rotation.Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure on page 10‑52
and
Vehicle Load Limits on
page 9‑10.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑55.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12‑2.
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.

A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
{WARNING
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{WARNING
Lifting a vehicle and getting
under it to do maintenance or
repairs is dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard
Warning Flashers on page 6‑3.
{WARNING
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire. To
help prevent the vehicle from
moving:
1. Set the parking brake firmly.
2. Put an automatic transmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine and do not restart while the vehicle
is raised.
4. Do not allow passengers to remain in the vehicle.
5. Place wheel blocks on both sides of the tire at the
opposite corner of the tire
being changed.
