1. Insert a thin object, such as a coin, in the slot between
the covers of the transmitter housing near the key ring
hole. Remove the bottom by twisting the coin.
2. Remove and replace the battery with a three
-volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.
Midgate
CAUTION:
It can be dangerous to drive with the cargo area
covered and the tailgate and midgate open
because carbon monoxide (CO) gas can come into
your vehicle. You can't see or smell CO. It can
cause unconsciousness and even death.
If you must drive with the cargo covers on and
the tailgate and midgate open or if electrical
wiring or other cable connections must pass
through the seal between the body and the
midgate:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on OUTSIDE AIR. That will force outside
air into your vehicle. See ªComfort
Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

2-81
Your vehicle has a Center High-Mounted Stoplamp
(CHMSL) located above the rear glass.
If items are loaded on the roof of the vehicle, care should
be taken not to block or damage the CHMSL unit.
Ashtray and Cigarette Lighter
The ashtray is located in the center console. Press the
raised area on the access door to use the ashtray.
NOTICE:
If you store paper or other things that burn in
your ashtray, they could be set on fire by
cigarettes or other smoking materials. That could
cause a fire and possibly damage your vehicle.
Do not store papers and other things that burn
in your ashtray.
To remove the ashtray, first locate the indentation on the
right side of the ashtray. Then place your fingertip in the
indentation and pry the ashtray out.
To use the cigarette lighter, push it in all the way, and let
go. When it's ready, it will pop back out by itself.
NOTICE:
Holding a cigarette lighter in with your hand
while it's heating can make it overload, damaging
the lighter and the heating element. Just push the
lighter all the way in and let go. When it's done,
it will pop back by itself.

Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will
come on when you start
your engine and may stay
on for several seconds.
That's normal.
If the light stays on, or comes on when you're driving,
your vehicle needs service. If the regular brake system
warning light isn't on, you still have brakes, but you
don't have anti
-lock brakes. If the regular brake system
warning light is also on, you don't have anti
-lock brakes
and there's a problem with your regular brakes. See
ªBrake System Warning Lightº earlier in this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210
F (100
C) or less. If you are pulling a
load or going up hills, it is normal for the temperature to
fluctuate and approach the 250
F (122
C) mark. If the
gage reaches the 260
F (125
C) mark, it indicates that
the cooling system is working beyond its capacity.
See ªEngine Overheatingº in the Index.

2-112
LOW COOLANT Message
This message is displayed
when the cooling system
is low on coolant.
The engine may overheat. See ªEngine Coolantº in the
Index and have your vehicle serviced as soon as you can.
CHECK COOLANT TEMP Message
This message is displayed
when the cooling system
temperature gets hot.
Check the coolant temperature gage and the coolant
level. See ªEngine Coolantº, ªEngine Coolant
Temperature Gageº and ªEngine Overheatingº in the
Index for further information.
ENGINE OVERHEATED Message
This message is displayed
when the cooling system
temperature gets too hot.
This message will be displayed after the air conditioning
system has automatically turned off for the engine
coolant protection mode. See ªEngine Overheatingº in
the Index for further information.
REDUCED ENGINE POWER Message
This message is displayed
when the cooling system
temperature gets too hot
and the engine further
enters the engine coolant
protection mode.

2-117
STABILITY SYSTEM DISABLED Message
The STABILITY SYSTEM
DISABLED message
indicates that the stability
enhancement system has
been temporarily disabled.
There are three conditions that can cause this message to
appear. One condition is overheating, which could
occur if the stability enhancement system activates
continuously for an extended period of time.
The STABILITY SYSTEM DISABLED message will
also be displayed if the brake system warning light is on.
See ªBrake System Warning Lightº in the Index.
Finally, the message could be displayed if the stability
system takes longer than usual to complete its diagnostic
checks due to driving conditions. The STABILITY
SYSTEM DISABLED message will turn off as soon as
the conditions that caused the message to be displayed
are no longer present. See ªStabilitrak Systemº in
the Index.

Comfort Controls
Electronic Climate Control System
Fan Knob
The knob on the left side of the electronic climate
control panel regulates the fan speed. To manually
increase airflow, turn the knob clockwise. To manually
decrease airflow, turn it counterclockwise.
OFF: If the knob is in OFF, outside air will still enter
the vehicle, and will be directed based on the position of
the mode knob. The temperature can also be adjusted
using the temperature knob.
AUTO (Automatic Operation): If the knob is in
AUTO, the fan speed will vary as the system maintains
the selected temperature.When both the fan knob and mode knob are in the
AUTO position, the system will then automatically
maintain the desired cabin temperature selected.
Manual operation is also available.
Temperature Knob
The middle knob on the control panel lets you select
the desired air temperature in your vehicle. Turn the
knob clockwise toward 82
F (28
C) for warmer air.
Turn the knob counterclockwise toward 66
F (19
C)
for cooler air.
(Full Hot): If you turn the temperature knob past
82
F (28
C), the system will go into the ªfull hotº
mode. The system will remain at that maximum heating
setting and the fan will blow at the speed to which the
fan knob is set. If the fan is in AUTO, it will run at
full speed.
(Full Cold): If you turn the temperature knob past
66
F (19
C), the system will go into the ªfull coldº
mode. The system will remain at that maximum cooling
setting and the fan will blow at the speed to which the
fan knob is set. If the fan is in AUTO, it will run at
full speed.

3-6 Air Conditioning
On hot days, open the windows long enough to let hot
air inside escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
The A/C mode allows the air coming into your vehicle
to be cooled. This mode is useful for normal cooling
on hot days.
Use A/C with recirculation on to allow the air inside
your vehicle to be recirculated. This mode will help to
maximize your air conditioner's performance and your
vehicle's fuel economy. This mode also cools the air the
fastest and can be used to keep unwanted odors and/or
dust from entering the vehicle.
When using the air conditioner, in manual mode, turn
off the recirculation mode and use the outside air mode
after the vehicle reaches a comfortable interior
temperature. When the right knob on the control panel
is between floor and defrost, the recirculation feature
will not function. This helps reduce window fogging.
Passenger Compartment Air Filter
Your vehicle is equipped with a passenger compartment
air filter which filters outside air entering the vehicle.
For information on replacing the filter see ªPassenger
Compartment Air Filterº in the Index.
Heating
The heater works best if you keep your windows closed
while using it. On cold days, when using manual mode,
use the floor or bi
-level mode with the temperature knob
in the red area.
On cold days, approximately 32
F (
-0
C) or lower,
you may experience differences in how the transmission
shifts until the engine is warm. This feature automatically
reduces the time it takes for the engine to reach normal
operating temperature and shortens the time it takes the
heater to reach full output.
If you use the engine coolant heater before starting
your engine in cold weather, 20
F (
-8
C) or lower,
the heating system will produce warmer air faster to
heat the passenger compartment.
The use of an engine coolant heater also reduces the
time it takes for the engine to reach normal operating
temperature. For more information, see ªEngine Coolant
Heaterº in the Index.

3-8 Ventilation System
Your vehicle has air outlets
in the center and on the
sides of the instrument
panel. There are also two
outlets located on the back
of the center console for the
rear seat passengers.
You can move the louvers from side
-to-side and
up and down to direct the flow of air. The driver's and
passenger's side outlets can be closed.The two outlets, located on the rear of the center
console, can also be closed. Turn the thumbwheel to the
left to shut off air flow or to the right to allow air flow.
When you close an outlet, it will increase the flow of air
coming out of any outlets that are open. The center
outlet, located on the instrument panel, does not
completely shut off airflow.
For mild outside temperatures when little heating or
cooling is needed, use outside air to direct outside air
through your vehicle.
Your vehicle's ventilation system supplies outside air to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air inlet
grilles, through the vehicle, and out the air exhaust valves.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running, unless you have the
recirculation mode active. For more information on the
recirculation button, see ªAir Conditioningº earlier in
this section.

3-9
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, turn the
fan knob all the way to the right for a few moments
before driving. This helps clear the intake ducts of
snow and moisture, and reduces the chance of
fogging the inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

The use of non
-GM approved hood air deflectors
may adversely affect the performance of the heating
and air conditioning system.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your
audio system even after the ignition is turned off.
See ªRetained Accessory Powerº in the Index.
