Daytime Running Lamps
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
first sold in Canada.
The DRL system will come on when the following
conditions are met:
•the ignition is on,
•the exterior lamps control in DRL mode and not in
the defeat position.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’tbe
on. The instrument panel will be lit.
When you turn the headlamp switch off, the headlamps
will go off, and your DRL lamps will illuminate.
Turn the exterior lamp control to the defeat position or
shift into PARK (P). The DRLs will stay off until the
control is toggled again or the vehicle is shifted out
of PARK (P).
This procedure applies only to vehiclesfirst sold in
the United States.

that are included with any electrical equipment that
you install.
The accessory power outlets are located on the driver’s

to the power accessory outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information on
the power accessory plugs.

temperature inside your vehicle.
A/C (Air Conditioning):This setting will begin to cool
and dehumidify the air inside of your vehicle.

Rear Air Conditioning and
Heating System
Your vehicle may have a rear heating and
air-conditioning system. This system regulates the
temperature, the fan speed and the air delivery for
the rear-seat passengers only. It also works with the
main climate-control system in your vehicle.
Use this control panel when you would like to maintain
a separate temperature setting. Adjust the direction
of the airflow or adjust the fan speed for the rear-seat
passenger(s).The rear control panel for this system is located in the
second row behind the driver in the rear of your vehicle.
A rear-seat passenger can use this control panel to
personally adjust the temperature, the direction of the
airflow and the fan speed for the rear-seating area.
The fan knob located on the front climate control panel
must be turned to REAR CNTL to allow a rear-seat
passenger to use the control panel in the rear-seating
area. Performing this action disables the front control
panel. To return control to this panel, move the fan knob
out of REAR CNTL. Front Climate-Control Panel

of the vehicle will remain at cabin temperature.
Be sure to keep the area under the front seats clear of
any objects so that the air inside of your vehicle can
circulate effectively.

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 is used properly.
There are two modes to clear fog or frost from your
windshield and side windows.
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. For best results, clear all snow and ice from the
windshield before defrosting.
Turn the knob on the right of the climate control panel
to select the defog or defrost mode.
-(Blend):With this setting, the outside air comes out
of both thefloor and defroster outlets. Adjust the
temperature knob for warmer or cooler air. The air
conditioning compressor may operate in this setting to
dehumidify the air.
1(Defrost):This setting operates the defroster.
Most of the air comes out near the windshield, with
some going to thefloor outlets and front side windows.
The air conditioning compressor may operate in this
setting to dehumidify the air.
The blend setting is useful for cold weather with a large
number of passengers or very humid conditions to
help keep the windshield clear. Use defrost to remove
fog or ice from the windshield quickly in extremely
cold conditions. The temperature knob should be in the
red area and the fan control toward high. Do not
drive the vehicle until all the windows are clear.

Rear Window Defogger
Press this button to turn the rear window defogger on or
off. Be sure to clear as much snow from the window
as possible.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window and will only
work when the ignition is RUN.
The rear window defogger will turn off several minutes
after the button is pressed. If turned on again, the
defogger will run for several more minutes before turning
off. The defogger can also be turned off by pressing
the button again or by turning off the engine.
Notice:Don’t use a razor blade or something else
sharp on the inside of the rear window. If you
do, you could cut or damage the defogger and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape,
a decal or anything similar to the defogger grid.
Outlet Adjustment
Use the outlets located
near the center and on the
sides of the instrument
panel to change the
direction of airflow.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block theflow of air into your 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 your vehicle more
effectively.
