#(Fog lamps) (If Equipped):Push the fog lamps
button to turn them on and off. SeeFog Lamps
on page 3-15for additional information.
Daytime Running Lamps (DRL)/
Automatic Headlamp System
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. DRL lamps are required
to function at all times on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered.
The DRL system will make the low-beam headlamps
come on at reduced brightness when the following
conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness. The turn
signal, taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
3-14

When it is dark enough outside, the DRL will turn off
and the vehicle’s headlamps and parking lamps will turn
on. The other lamps that come on with the headlamps
will also come on.
When it is bright enough outside, the headlamps will go
off and the DRL will come on.
To idle the vehicle with the DRL off, turn the exterior
lamp control off and then do one of the following:
Turn the exterior lamp control to the parking lamp
position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to off and
back to AUTO.
This feature is not available for vehicles rst sold in
Canada.
To turn off the automatic headlamp feature when it
is dark outside, move the exterior lamp control to the
parking lamp position. The parking lamps remain on
and the headlamps turn off. The fog lamps also go on
if they were on previously.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
For vehicles with fog lamps, the button is located in the
center of the exterior lamps control on the left side of
the steering column.
#:Press to turn the lamps on or off.
While the high-beam headlamps are on, the fog lamps
are off.
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
after the ignition has been turned to off, the exterior
lamps will turn off after about 10 minutes. This protects
the battery from being drained.
Use the exterior lamp control to turn the lamps back on,
if they are still needed.

OFF:Turn the fan control knob to this position to turn
the climate control system off.
9(Fan):Turn the knob by this symbol, located on
the left side of the climate control panel, clockwise or
counterclockwise to increase or decrease the fan speed.
The fan speed is temporarily reduced when adjusting
modes, but resumes the original speed when the
transition to the new mode is complete.Temperature Control:Turn clockwise or
counterclockwise to increase or decrease the
temperature inside the vehicle.
Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the direction of the
airow inside the vehicle.
Select from the following air delivery modes:
H(Vent):Air is directed to the instrument panel outlets.
If driving in city traffic, and the vehicle is stopped and
idling, or the weather is hot, turning on the recirculation
mode helps to prevent the air inside the vehicle from
becoming stale. After ve minutes recirculate will allow
some outside air into the vehicle.
)(Bi-Level):Air is divided between the instrument
panel and oor outlets. Some air may be directed toward
the windshield. Slightly cooler air is directed to the
instrument panel outlets and warmer air is directed
to the oor outlets.
6(Floor):Air is directed to the oor outlets, with
some air directed toward the side window outlets and
windshield.
In this mode, the system automatically uses outside air.
The air conditioning compressor will be engaged unless
the outside temperature is 40°F (4°C) or below.
3-22

-(Defog):This mode clears the windows of fog or
moisture. Air is divided between the windshield and
the side window outlets, and the oor outlets. In this
mode, the system turns recirculation off and runs the air
conditioning compressor unless the outside temperature
is near or below freezing. Pressing the recirculation
button will have no effect other than turning on the
indicator light while in defog mode.
0(Defrost):This mode clears the windows of fog or
frost more quickly. Air is directed to the windshield and
the side window outlets, with some air directed to the oor
outlets. In this mode, the system turns recirculation off
and runs the air conditioning compressor unless the
outside temperature is near or below freezing. Pressing
the recirculation button will have no effect other than
turning on the indicator light while in defrost mode.
#(Air Conditioning):Press to turn the air
conditioning system on or off. An indicator light turns on
to show that the air conditioning is on. Air conditioning
can be selected in any mode as long as the fan switch is
on. The indicator light changes with each button press
even when conditions prevent operation.On hot days during the vehicle’s initial start-up, 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.
For quicker cool down on hot days, do the following:
1. Select
Hmode.
2. Press
h.
3. Press
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
The air conditioning system removes moisture from
the air, so a small amount of water might drip under
the vehicle while idling or after turning off the engine.
This is normal.
Using these settings together for long periods of time
may cause the air inside the vehicle to become too dry.
To prevent this, after ve minutes recirculate will allow
some outside air into the vehicle.
3-23

h(Recirculate):Press to turn the recirculation mode
on. An indicator light comes on to show that recirculation
is on. This mode recirculates and helps to quickly heat or
cool the air inside the vehicle. It can be used to prevent
the outside air and odors from entering the vehicle.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode. To prevent the air inside the vehicle
from becoming stale, after ve minutes recirculation lets
some outside air into the vehicle.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press turn the rear window defogger on or
off. An indicator light comes on to show that the
rear window defogger is on.The rear window defogger only works when the ignition
is in ON/RUN. The rear window defogger stays on for
about 20 minutes after the button is pressed. If turned on
again, the defogger only runs for about 20 minutes before
turning off. The defogger can also be turned off by turning
off the engine.
The heated outside rearview mirrors, help to clear fog
or frost from the surface of the mirror when the rear
window defog button is pressed.
Do not drive the vehicle until all windows are clear.
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.
