Fog Lamps
For vehicles with fog lamps, the button is located on the
instrument panel, to the left of the steering wheel.
The ignition must be on to use the fog lamps.
#:Press to turn the fog lamps on off. An indicator
light on the button comes on when the fog lamps are on.
The parking lamps automatically turn on and off when
the fog lamps are turned on and off.
The fog lamps will turn off while the high-beam
headlamps are turned on.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Instrument Panel Brightness

is located on the instrument
panel to the left of the
steering wheel.
Turn the knob clockwise to brighten the lights or
counterclockwise to dim them.
Dome Lamp

Entry/Exit Lighting
The lamps inside the vehicle will go on when any door is
opened. These lamps fade out about 20 seconds after all
of the doors have been closed or when the ignition is
turned to ON/RUN. These lamps will also go on when
pressing the trunk release, unlock symbol, or the horn
symbol button on the Remote Keyless Entry System
(RKE) Transmitter.
After the key is removed from the ignition, the lamps
inside the vehicle stay on for about 20 seconds to
provide an illuminated exit.
Mirror Reading Lamps
The vehicle may have reading lamps on the rearview
mirror. Press the button near each lamp to turn the
reading lamps on and off.
Electric Power Management
This vehicle has Electric Power Management (EPM),
an advanced control system. It estimates the battery’s
temperature and state of charge and then adjusts
the voltage for best performance and extended life
of the battery.When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When the
state of charge is high, the voltage is lowered slightly to
prevent overcharging. If the vehicle has a voltmeter gage
or voltage display on the Driver Information Center (DIC),
you may see the voltage move up or down. This is
normal. If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the following
loads are on: headlamps, high beams, fog lamps, rear
window defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer loads, and
loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the battery.
It does this by balancing the generator’s output and the
vehicle’s electrical needs. It can increase engine idle
speed to generate more power, whenever needed.
It can temporarily reduce the power demands of some
accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable to
the driver.

To change the current mode, select one of the following:
9(Off):Turn the fan control to this position to turn
the fan off.
Temperature Control: Turn clockwise or
counterclockwise to increase or decrease the
temperature.
9(Fan Control): Turn clockwise or counterclockwise to
increase or decrease the fan speed. In any setting other
than off, the fan will run continuously with the ignition on.
The fan must be turned on to run the air conditioning
compressor.
Air Delivery Mode Control: Turn clockwise or
counterclockwise to change the direction of the
airflow inside the vehicle.
Select from the following modes:
H(Vent): Air is directed to the instrument panel
outlets.
)(Bi-Level): Air is divided between the instrument
panel outlets and the floor outlets. Cooler air is directed
to the upper outlets and warmer air to the floor outlets.
6(Floor): Air is directed to the floor outlets, with some
air directed to the windshield and side windows.
-(Defog): This mode clears the windows of fog or
moisture. Air is directed to the windshield, side window,
and floor outlets. To defog the windows faster, turn the
temperature control knob clockwise to the warmest
setting. In this mode, the system runs the air conditioning
compressor.
0(Defrost): This mode removes fog or frost from
the windshield more quickly. Air is directed to the
windshield, with some air directed to the side window
outlets and the floor outlets. To defrost the windows
faster, turn the temperature control knob clockwise to
the warmest setting. In this mode, the system runs
the air conditioning compressor.
For best results, clear all snow and ice from the
windshield before defrosting.
#(Air Conditioning): For vehicles with air
conditioning, press this button to turn the air conditioning
system on or off. An indicator light comes on to show that
the air conditioning is on.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.

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 about 15 minutes
after the button is pressed. If turned on again, the
defogger only runs for about seven minutes before
turning off. If the vehicle is moving faster than 50 mph
(80 kph), the rear defogger will stay on. The defogger
can also be turned off by turning off the engine.
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
Use the thumbwheels located next to and below the air
outlets to change the direction of the airflow and to
open and close the outlets.
Operation Tips
•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into the vehicle.
•Use of non-GM approved hood deflectors 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.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine is
started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. See Brake System Warning Light on
page 4-26.
For vehicles with a Driver Information Center (DIC),
see DIC Warnings and Messages on page 4-38 for all
brake related DIC messages.
Enhanced Traction System (ETS)
Indicator/Warning Light
For vehicles with the

System (ETS), this light
serves as an indicator
and warning light.
This light comes on briefly while the engine is started.
If it does not, have the vehicle serviced by your dealer/
retailer. If the system is working normally the indicator
light then goes off.
If the indicator/warning light is on and not flashing, the
ETS system could have been disabled. Check all related
Driver Information Center (DIC) messages to determine
whether the system has been turned off or if the system
is not working properly and the vehicle requires service.
If the ETS has been disabled, wheel spin is not limited.
If the indicator/warning light is on and flashing, the ETS
is actively working. The LOW TRACTION DIC message
also appears when the system is actively limiting
wheel spin.
