Headlamps on Reminder
A warning chime will sound if the exterior lamp
control is left on in either the headlamp or parking
lamp position and the driver’s door is opened
with the ignition off. SeeLights On Reminder on
page 213for additional information.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional daytime running lamps
are required on all vehicles rst sold in Canada.
The DRL system will make the turn signal lamps
come on when the following conditions are met:
It is still daylight and the ignition is in ON
or START.
The exterior lamp control is in off or AUTO and
the headlamps are off.
The automatic transmission is not in PARK (P).When DRL are on, only your front turn signal
lamps will be on. No other exterior lamps will
be on. Your instrument panel cluster will not be
lit up either.
When the exterior lamp control is in AUTO and it
is dark enough outside, the DRL will turn off
and the low-beam headlamps will turn on. When it
is bright enough outside, the low-beam headlamps
will go off, and the DRL will turn back on. If you
start your vehicle in a dark garage, the automatic
headlamp system will come on immediately.
Once you leave the garage, it will take about
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that
delay, your instrument panel cluster may not be as
bright as usual. Make sure your instrument
panel brightness lever is in the full bright position.
SeeInstrument Panel Brightness on page 184.
181

If it is dark enough outside and the exterior lamp
control is off, a Headlamps Suggested message
will appear on the Driver’s Information Center
(DIC) display. This message informs the driver that
turning on the exterior lamps is recommended
even though the DRL are still on. Turning the
exterior lamp control to AUTO or to the low-beam
headlamp position will turn off the DRL and
cancel the Headlamps Suggested message.
If the parking lamps or the fog lamps were turned
on instead, the DRL will still turn off and the
Headlamps Suggested message will be displayed.
You can turn it off by pressing the OK button if
you have the Navigation audio system or the
CLR (Clear) button if you have the base audio
system.
To drive your vehicle with the DRL off, turn the
exterior lamp control off. Then turn on the fog lamps
or parking lamps, and the DRL will turn off.
The Headlamps Suggested message will appear on
the DIC display. This will work regardless of gear
position and whether or not the parking brake is set.
As with any vehicle, you should turn on the
regular headlamp system when you need it.Light Sensor
The light sensor for the DRL and AUTO headlamp
feature is located on top of the instrument panel.
If you cover the sensor, it will prevent it from
sensing light, and the exterior lamps or the
Headlamps Suggested message will appear on
the DIC whenever the ignition is on.
182

Fog Lamps
Use the fog lamps for better vision in foggy or
misty conditions.
The fog lamp control is located on the turn
signal/multifunction lever.
-(Fog Lamps):The band with/or next to this
symbol is used to turn the fog lamps on and off.
The parking lamps must be on for the fog lamps
to work.
To operate the fog lamps:
To turn the fog lamps on, turn the fog lamp
band on the lever up to the dot and release
it. The band will return to its original position.
To turn the fog lamps off, turn the for lamp band
up to the dot and release it. The band will return
to its original position, and the fog lamps will
turn off. If the high-beam headlamps are turned
on, the fog lamps will also turn off. They will turn
back on again when you switch back to
low-beam headlamps.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been
left on, the exterior lamps will turn off about
10 minutes after the ignition is turned to OFF.
This protects against draining the battery in case
the headlamps or parking lamps have been
left on. The battery saver does not work if the
headlamps are turned on after the ignition is
turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to
turn the lamps back on.
183

Instrument Panel Brightness
The lever for this
feature is located on the
overhead console.
Slide the lever toward the symbol to brighten the
lights or away from it to dim them.
If you slide the lever all the way toward the
symbol past the resistance point, the interior lamps
will come on. To turn them off, slide the lever
back toward the minimum brightness setting.
Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior
lamp control when a door is opened or if the
Remote Keyless Entry (RKE) transmitter unlock
button is pressed. If activated by the (RKE),
the lighting will remain active for about 25 seconds.
The entry lighting system uses the light sensor
on the instrument panel; so it must be dark outside
in order for the lamps to turn on. The lamps turn
off about 25 seconds after the last door is
closed. They will dim to off if the ignition key is
turned to ON, or immediately turn off if the power
locks are used.
184

Parade Dimming
This feature prohibits dimming of the instrument
panel displays and backlighting during daylight
hours when the key is in the ignition and the
headlamps are on. This feature operates with the
light sensor and is fully automatic. When the light
sensor reads darkness outside and the parking
lamps are active, the instrument panel displays can
be adjusted by sliding the instrument panel
brightness lever toward the symbol to brighten or
away from the symbol to dim the lighting.
Reading Lamps
The reading lamps are located on the overhead
console. These lamps come on automatically when
any door is opened.
For manual operation, press the button next to
each lamp to turn it on or off.
If the reading lamps are left on, they automatically
shut off 10 minutes after the ignition has been
turned off.
Electric Power Management
The vehicle has Electric Power Management
(EPM) that estimates the battery’s temperature and
state of charge. It 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.
185

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. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 232.Battery Run-Down Protection
Your vehicle has a feature to help prevent the
battery from being drained, in case the underhood
lamp, vanity mirror lamps, cargo lamps, reading
lamps, console, or glove box lamps are
accidentally left on, or something is left plugged
into the accessory power outlet or cigarette lighter.
If any of the accessory lamps are left on, they
will automatically time-out after about 20 minutes.
To reset the battery protection, all of the above
lamps must be turned off or the ignition must be in
the Acc. position.
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
186

Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear fog from your windshield.
Use the defog mode to clear the windows of fog
or moisture and warm the passengers. Use
the defrost mode to remove fog or frost from the
windshield more quickly.
yNz(Mode):Press this button until defog
appears on the display.
-(Defog):This mode directs the air between the
windshield, oor outlets and side windows.
When this mode is selected, the system turns off
recirculation and runs the air-conditioning
compressor unless the outside temperature is at
or below freezing. If recirculation mode is selected
while in defog mode, it will be cancelled after
10 minutes.
If there is fog on the side windows, turn the
thumbwheel on the outboard outlets to the side
window defog position. SeeOutlet Adjustment on
page 194for more information.
0(Defrost):Pressing defrost directs most of the
air to the windshield, with some air directed to
the side windows. In this mode, the system
will automatically turn off recirculation and run the
air-conditioning compressor, unless the outside
temperature is at or below freezing.
This mode may also cause the fan speed and air
temperature to increase.
If there is fogging on the side windows, turn the
thumbwheel on the outboard outlets to the
side window defog position. SeeOutlet Adjustment
on page 194for more information. Do not drive
the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON.
=(Rear Window Defogger):Press this button
to turn the rear window defogger on or off.
Be sure to clear as much snow from the rear
window as possible.
193

Operation Tips

Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the ow of air into your 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
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of
the pollen from the air entering your vehicle.
Like your vehicle’s engine air cleaner/lter, it needs
to be changed periodically. SeeScheduled
Maintenance on page 462.
Using the climate control system without the
passenger air lter installed may allow water or
other debris to enter the system. This could cause
a water leak or noises. Make sure to install a
new air lter after removing the old one.The passenger compartment air lter is located
underneath the hood below the windshield
wiper arm on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 342
for more information on location.
Use the procedure listed below to replace the
passenger compartment air lter:
1. Turn the ignition to ON with the engine off.
2. Turn on the windshield wipers and turn them
off again when the wipers are straight on the
windshield.
This allows you access to the leaf screen.
The passenger compartment air lter is
located under the leaf screen.
195

Engine Speed Limiter
This feature prevents the engine from operating at
too many revolutions per minute (rpm). When
the engine’s rpms are too high, the throttle
is closed to reduce speed. If this is not sufficient,
then the fuel supply to the engine will be
limited. When the rpms return to normal, the fuel
supply will return to normal. This helps prevent
damage to the engine.
Safety Belt Reminder Light
When the key is turned to ON or START, a chime
will come on for several seconds to remind
people to fasten their safety belts.
The safety belt light will
also come on and
stay on for several
seconds, then it will
ash for several more.
If the driver’s belt is already buckled, the chime
will not come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for
malfunctions. The light tells you if there is an
electrical problem. The system check includes the
airbag sensors, the airbag modules, the wiring and
the diagnostic module. For more information on the
airbag system, seeAirbag System on page 70.
This light will come
on when the ignition
key is turned to ON
and it will ash for
a few seconds.
Then the light should go out. This means the
system is ready. If it does not go out, have your
vehicle serviced right away.
201

If the airbag readiness light stays on after you
start the vehicle or comes on while you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
If there is a problem with the airbag system in
your vehicle, the Service Air Bag message
will appear on the Driver Information Center (DIC)
display. SeeDIC Warnings and Messages on
page 232for more information.
Passenger Airbag Status Indicator
Your rearview mirror has a passenger airbag
status indicator.
When the ignition key is turned to ON or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check.
