may slightly increase to help prevent
fogging. If the climate control system does
not detect possible window fogging, it
returns to normal operation.
To turn Auto Defog off or on, see“Climate
and Air Quality” underVehicle
Personalization 0114.
Ionizer : If equipped with an ionizer, this
feature helps to clean the air inside the
vehicle and remove contaminants such as
pollen, odors, and dust. If the climate
control system is on and the ionizer is
enabled, Ionizer On will be displayed. To
turn the ionizer on or off, see “Climate and
Air Quality” underVehicle Personalization
0 114.
Rear Window Defogger
K:Press to turn the rear window defogger
on or off. An indicator light on the button
comes on to show that the rear window
defogger is on. The rear window defogger
only works when the engine is running.
It turns off when the ignition is turned off
or in ACC/ACCESSORY.
The rear window defogger can be set to
automatic operation. See “Climate and Air
Quality” underVehicle Personalization 0114.
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,
or after five minutes if the outside
temperature is not as cold.
The upper gridlines on the rear window are
antenna lines and are not intended to heat
when the defogger is activated.
The heated outside mirrors turn on when
the rear window defogger button is on and
help to clear fog or frost from the surface of
the mirror. See
Heated Mirrors028.
Caution
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.
Heated and Ventilated Seats
MorL:If equipped, pressMorLto
heat the driver or passenger seat.
Cor{: If equipped, pressCor{to
ventilate the driver or passenger seat. See

Remote Start Climate Control Operation :
The climate control system may run when
the vehicle is started remotely. If the vehicle
has heated or ventilated seats, they may
come on during a remote start. See Remote
Vehicle Start 013 and
Heated and Ventilated Front Seats 040.
Sensors
The solar sensor, 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.
Do not cover the sensor; otherwise the
automatic climate control system may not
work properly.

Operation Tips
.Clear away any ice, snow, or leaves from
the air inlets at the base of the
windshield that can block the flow of air
into the vehicle.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle.
.Use of non-GM approved hood deflectors
can adversely affect the performance of
the system.
.Keep the path under all seats clear of
objects to help circulate the air inside the
vehicle more effectively.
.If fogging reoccurs while in vent or
bi-level modes with mild temperature
throughout the vehicle, turn on the air
conditioner to reduce windshield fogging.
Maintenance
Passenger Compartment Air Filter
The filter reduces 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. See
Maintenance Schedule
0 323.
See your dealer regarding replacement of
the filter.
Service
All vehicles have a label underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.
The air conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also

The Certification/Tire label may also
show the maximum weights for the
front and rear axles, called the Gross
Axle Weight Rating (GAWR). To find out
the actual loads on the front and rear
axles, weigh the vehicle at a weigh
station. Your dealer can help with this.
Be sure to spread the load equally on
both sides of the centerline.Caution
Overloading the vehicle may cause
damage. Repairs would not be covered by
the vehicle warranty. Do not overload the
vehicle.
{Warning
Things inside the vehicle can strike
and injure people in a sudden stop or
turn, or in a crash.
.Put things in the cargo area of the
vehicle. In the cargo area, put
them as far forward as possible.
Try to spread the weight evenly.
(Continued)
Warning (Continued)
.Never stack heavier things, like
suitcases, inside the vehicle so
that some of them are above the
tops of the seats.
.Do not leave an unsecured child
restraint in the vehicle.
.Secure loose items in the vehicle.
.Do not leave a seat folded down
unless needed.
Starting and Operating
New Vehicle Break-In
Caution
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
800 km (500 mi). Do not make
full-throttle starts. Avoid downshifting
to brake or slow the vehicle.
(Continued)
Caution (Continued)
.Avoid making hard stops for the first
300 km (200 mi) or so. During this
time the new brake linings are not yet
broken in. Hard stops with new linings
can mean premature wear and earlier
replacement. Follow this breaking-in
guideline every time you get new
brake linings.
Following break-in, engine speed and load
can be gradually increased.
Ignition Positions
Vehicles with Keyless Access have
pushbutton starting.
