For quick cool down on hot days:
1. Select
H.
2. Select
@.
3. Select
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of the vehicle to become
too dry. To prevent this from happening, after the air in
the vehicle has cooled, turn off the recirculation by
pressing the outside air button.
The air conditioning system removes moisture from
the air, so a small amount of water might drip under
the vehicle while idling or after turning off the engine.
This is normal.
The air conditioning compressor cannot be turned on
when the fan is off.
@(Recirculation):Press to turn the recirculation
mode on. An indicator light comes on to show that
recirculation is on.
This mode recirculates and helps to quickly cool the air
inside the vehicle. It can be used to help prevent outside
air and odors from entering the vehicle.The air conditioning compressor also comes on.
Recirculation is not available in oor, defog and defrost
modes. If the recirculation button is pressed, the indicator
light ashes ve times and outside air will be delivered.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode.
;(Outside Air):Press to allow outside air to circulate
through the vehicle. An indicator light comes on to show
that outside air is on.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger only works when the ignition
is in ON/RUN.
<(Rear):Press to turn the rear window defogger on or
off. Be sure to clear as much snow from the rear window
as possible. An indicator light comes on to show that the
rear window defogger is on.
The rear window defogger turns off approximately
15 minutes after the button is pressed. If turned
on again, the defogger only runs for approximately
seven minutes before turning off.

If the vehicle speed is greater than 50 mph (80 km/h)
and the rear defogger is on, it remains on as long as the
speed is greater than 50 mph (80 km/h). The defogger
can also be turned off by turning off the engine.
For vehicles with the remote start feature, the rear
defogger automatically turns on if it is cold outside. When
the vehicle transitions out of the remote start mode, the
rear defogger turns off. SeeRemote Keyless Entry (RKE)
System Operation on page 2-4
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by the vehicle warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.
Outlet Adjustment
Turn the outlets and move the outlet vanes to change
the direction of the airow and to open and close
the outlets.
Operation Tips

inlets at the base of the windshield that may
block the ow of air into the vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.
Passenger Compartment Air Filter
The lter removes dust and pollen from the air which is
drawn into the vehicle. Airow reduction is an indication
that the lter needs to be replaced.
The lter should be replaced as part of routine scheduled
maintenance. SeeScheduled Maintenance on page 6-4
for replacement intervals. To nd out what type of lter to

Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there may
be a problem, check the section that explains what to do.
Follow this manual’s advice. Waiting to do repairs can be
costly and even dangerous.

Speedometer and Odometer
The speedometer shows the speed in both miles per
hour (mph) and kilometers per hour (km/h).

Operation and Displays on page 3-48.
The vehicle does not have to be running to check the
odometer mileage. Simply open the driver’s door and the
mileage briey displays.
If the vehicle ever needs a new odometer installed, the
new one will be set to the correct total mileage of the old
odometer.

displays the engine
speed in revolutions per
minute (RPM).
Notice:If the engine is operated with the
tachometer in the red warning area, the vehicle
could be damaged and the damages would not be
covered by the vehicle warranty. Do not operate the
engine with the tachometer in the red warning area.

Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing
and diagnostic module. For more information on the
airbag system, seeAirbag System on page 1-58.
The airbag readiness light
ashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
xed immediately.{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inate in a crash, or they could even inate
without a crash. To help avoid injury, have the
vehicle serviced right away.

when the ignition key is
turned on, but the engine is
not running, as a check
to show it is working.
It should go out once the engine is running. If it stays on,
or comes on while driving, there could be a problem with
the charging system or it could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the

Brake System Warning Light
The vehicle’s hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking both
parts need to be working well.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briey when the engine is
started. If it does not come on then, have it xed so it
will be ready to warn if there is a problem.When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
stays on if the parking brake does not fully release. If it
stays on after the parking brake is fully released, it means
the vehicle has a brake problem.
If the light comes on while driving, pull off the road
and stop carefully. Make sure the parking brake is fully
released. The pedal might be harder to push or, the pedal
could go closer to the oor. It can take longer to stop.
Try turning off and restarting the vehicle one or two times,
if the light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 4-31.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service. United StatesCanada
