speeds, the rear window defogger
may stay on continuously.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality”under
Vehicle Personalization on
page 5‑44. When Auto Rear Defog
is selected, the rear window
defogger turns on automatically
when the interior temperature is cold
and the outside temperature is
about 4°C (40°F) and below. The
auto rear defogger turns off
automatically after about
10 minutes. At higher vehicle
speeds, the rear window defogger
may stay on continuously.
The heated outside mirrors turn on
when the rear window defogger
button is on. They help to clear fog
or frost from the surface of the
mirrors.
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 the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.

Remote Start Climate Control
Operation: For vehicles with the
remote vehicle start feature, the
climate control system may run
when the vehicle is started remotely.
The system uses the driver's
previous settings to heat or cool the
inside of the vehicle. See Remote
Vehicle Start on page 2‑9.
The rear window defogger turns on
if it is cold outside.
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
automatic climate control system
may not work properly.
Rear Climate Control
System
For vehicles with a rear climate
control system, the settings can be
adjusted with the rear climate
control buttons and the touch
screen.

Additional air vents are located

cannot be adjusted.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
.Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
.Do not attach any devices to the
air vent slats. This restricts
airflow and may cause damage
to the air vents.
Maintenance
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
SeeMaintenance Schedule on
page 11‑3. To find out what type of
filter to use, see Maintenance
Replacement Parts on page 11‑14.
1. Open the glove box completely.

Starting and
Operating
New Vehicle Break-In
Notice: The vehicle does not
need an elaborate break-in. But it
will perform better in the long run
if you follow these guidelines:
.Do not drive at any one
constant speed, fast or slow,
for the first 805 km (500 mi).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
.During the first 1 000 km
(600 mi), avoid using more
than moderate acceleration
in lower gears and avoid
vehicle speeds above
110 km/h (68 mph).
.Between the first 1 000 km
(600 mi) and 5 000 km
(3,000 mi), heavy
acceleration in lower gears
can be used. Vehicle speeds

Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
SeeShifting Into Park on page 9‑19
and Engine Exhaust on page 9‑21.
If parking on a hill and pulling a
trailer, see Driving Characteristics
and Towing Tips on page 9‑60.
Automatic
Transmission
The automatic transmission has a
shift lever located on the console
between the seats.
P (Park): This position locks the
wheels. It is the best position to use
when starting the engine because
the vehicle cannot move easily.
{WARNING
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park on
page 9‑19 andDriving
Characteristics and Towing Tips
on page 9‑60.
Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. The regular brake must be
fully applied first and then the shift
