Headlamps on Reminder
A reminder chime will sound when the headlamps
or parking lamps are manually turned on and
your ignition is off and a door is open. To disable
the chime, turn the light off.
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 come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P).
The light sensor determines it is daytime.
When the DRL are on, only your DRL lamps will
be on. The taillamps, sidemarker, and other lamps
will not be on. The instrument panel will not be
lit up either.
When it begins to get dark, the automatic
headlamp system will switch from DRL to the
headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release.
For vehicles rst sold in Canada, the transaxle
must be in the PARK (P) position, before the DRL
lamps can be turned off.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
216

Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on the headlamps at the
normal brightness, along with the taillamps,
sidemarker, parking lamps, and the instrument
panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn
the exterior lamps switch to the off position
and then release. For vehicles rst sold in Canada,
the transaxle must be in the PARK (P) position,
before the automatic headlamp system can
be turned off.
The vehicle has a light sensor located on the top
of the instrument panel in the defroster grille
that regulates when the automatic headlamps turn
on. Be sure it is not covered, or the headlamps
will come on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.There is a delay in the transition between the
daytime and nighttime operation of the Daytime
Running Lamps (DRL) and the automatic headlamp
systems so that driving under bridges or bright
overhead street lights does not affect the system.
The DRL and automatic headlamp system will only
be affected when the light sensor detects a change
in lighting lasting longer than the delay.
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 approximately one minute for the automatic
headlamp system to change to DRL if it is
bright enough outside. During that delay, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 219.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 280.
As with any vehicle, you should turn on the regular
headlamp system when needed.
217

Fog Lamps
-(Fog Lamps):If your vehicle has fog lamps,
the button is located on the instrument panel
to the left of the steering column and below the
dome lamp override button.
The ignition must be in RUN and the parking
lamps must be on for the fog lamps to work.
To turn the fog lamps on, press the fog lamps
button. A light comes on in the instrument
panel cluster to let you know that the fog lamps
are on. Press the button again to turn the fog
lamps off.
When the fog lamps are turned on, the low-beam
headlamps automatically turn on.
The fog lamps turn off while you change to
high-beam headlamps. When the high-beam
headlamps go off, the fog lamps will come
on again.
Fog lamps should only be used in foggy conditions
since they could be distracting to oncoming
drivers in clear weather conditions.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Auxiliary Roof Mounted Lamp
If your vehicle has this feature, this button includes
wiring provisions for a dealer or a qualied
service center to install an auxiliary roof lamp.
This button is located
on the overhead
console.
When the wiring is connected to an auxiliary roof
mounted lamp, pressing the bottom of the
button will activate the lamp and illuminate an
indicator light at the bottom of this button. Pressing
the top of the button will turn off the roof mounted
lamp and indicator.
The emergency roof lamp circuit is fused at
30 amps, so the total current draw of the attached
lamps should be less than this value. The
attachment points for the roof lamp circuits are
two blunt cut wires located above the overhead
console, a dark green switched power wire and a
black ground wire.
218

For further information on roof mount emergency
lamp installation, please visit the GM Uptter
website at www.gmuptters.com or contact your
dealer.
If your vehicle has this button, your vehicle may
have the snow plow prep package. For further
information seeAdding a Snow Plow or Similar
Equipment on page 412.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel
lights.
The knob for this feature is located next to the
headlamp control.
Turn the knob clockwise or counterclockwise to
adjust the brightness of the instrument panel lights.
Turn the knob clockwise to return the instrument
panel cluster or radio display to full brightness
when the headlamps or parking lamps are on. To
turn on the dome lamps, turn the knob to the
farthest clockwise position.
Dome Lamps
The dome lamps come on when a door is opened.
The dome lamps can also be turned on by
turning the knob, located next to the exterior lamps
control, clockwise to the farthest position. In this
position, the dome lamps will remain on whether a
door is opened or closed.
Dome Lamp Override
E(Dome Lamp Override):Press the dome
override button, located next to the exterior lamps
control, to keep the dome lamps off when a
door is open. To set the lamps to the automatic
operation, press the button again so that it is
extended. With the button in this position,
the dome lamps will come on when a door is
opened.

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. 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 270.
Battery Run-Down Protection
This feature shuts off the dome, and reading
lamps if they are left on for more than 10 minutes
when the ignition is off. This will keep the
battery from running down.

2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F
(23°C) temperature setting and allow about
20 minutes for the system to regulate. Use the
driver’s or passenger’s temperature buttons to
adjust the temperature setting as necessary. If
you choose the temperature setting of 60°F
(15°C), the system will remain at the maximum
cooling setting. If you choose the temperature
setting of 90°F (32°C), the system will remain
at the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to
heat or cool any faster.
Be careful not to cover the solar sensor located on
the top of the instrument panel near the
windshield. This sensor regulates air temperature
based on sun load and also turns on your
headlamps. For more information on the solar
sensor, see “Sensors” later in this section.To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air
is available. The length of delay depends on
the engine coolant temperature. Pressing the fan
switch will override this delay and change the
fan to a selected speed.
O(On/Off):Press this button to turn off the
climate control system. Outside air will still enter
the vehicle, and will be directed to the oor.
This direction can be changed by pressing the
mode button. Recirculation can be selected once
you have selected vent or bi-level mode. The
temperature can also be adjusted using either
temperature button. If you adjust the air delivery
mode or temperature settings with the system
off, the display will illuminate briey to show you
the settings and then return off. Press the
on/off button or the up down arrows on the fan
switch, the defrost button, AUTO button, or the air
conditioning button to turn the system on when
it is off.

Tow/Haul Mode Light
This light is displayed
when the Tow/Haul
mode has been
activated.
For more information, seeTowing a Trailer on
page 422andTow/Haul Mode on page 149.
Fuel Gage
The fuel gage, when the ignition is on, tells you
about how much fuel you have left in your tank.
The gage will rst indicate empty before you
are out of fuel, and you should get more fuel as
soon as possible.
When the fuel tank is low, the FUEL LEVEL LOW
message will appear in the Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 270for more information.
