Your exterior lamps knob
is located on your
instrument panel to the left
of the steering wheel.

turn off the Daytime Running Lamps (DRL) and the
automatic headlamps. An indicator will illuminate when
the position is selected. This position is not available
for vehicles rst sold in Canada.
i(Automatic DRL/AHS):Turning the knob to this
symbol puts the system into automatic headlamp mode.
An indicator will illuminate when the position is

Automatic Headlamp System
When it is dark enough outside, your Automatic
Headlamp System will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will also be on.
Your vehicle is equipped with a light sensor on the
top of the instrument panel. Be sure it is not covered or
the system will be on whenever the ignition is on.
The system may also turn on your lights 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 sees a change in lighting lasting
longer than the delay.
3-15

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 control is in the full
bright position.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is off.
Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake,
shift out of park or turn the exterior lamp control to
the off position as described in “Exterior Lamps” listed
previously.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on, the driver’s door
is open and your ignition is in LOCK or ACCESSORY.
To turn the tone off, turn the knob all the way
counterclockwise. In the automatic mode, the headlamps
turn off once the ignition key is in LOCK.
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 your headlamps come on
at reduced brightness when the following conditions
are met:
The ignition is on
the exterior lamps knob is in automatic
headlamp mode
the light sensor detects daytime light
the transmission is not in PARK (P)
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
If the knob is in off mode, outside air will still enter the
vehicle, and will be directed based on the position of the
mode knob. The temperature can still be adjusted
using the temperature knob.
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of the air
to the instrument panel outlets; then directs most of
the remaining air to the oor outlets. A little air is
directed toward the windshield and the side window
outlets. Cooler air is directed to the upper vents
and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with a little air directed to the windshield and
the side window outlets. The recirculation button
cannot be selected while in oor mode.
h(Recirculation):Recirculation mode is used to
recirculate the air inside of your vehicle. When this
button is pressed, an indicator light in the button
will come on to let you know that it is active. Use this
mode to help prevent outside odors and/or dust
from entering your vehicle or to help cool the air inside
of your vehicle more quickly. The air conditioning
compressor will also come on when this mode is
activated. While in recirculation mode, the windows may
fog when the weather is cold and damp. To clear the
fog, select either the defog or defrost mode and increase
fan speed. Recirculation mode shuts off when the
engine is turned off.
3-21

Temperature Control
Driver’s Side:The lever on the left side of the climate
control panel is used to raise or lower the temperature
on the driver’s side of the vehicle. Slide the lever
up or down to adjust the temperature.
Passenger’s Side:The lever on the right side of the
climate control panel is used to raise or lower the
temperature on the passenger’s side of the vehicle.
Slide the lever up or down to adjust the temperature.
This lever also adjusts the temperature to the rear seat
outlets.
When the temperature outside is 0°F (-18°C) or lower,
use the engine coolant heater, if equipped, to provide
warmer air, faster to your vehicle.
#(Air Conditioning):Press this button to turn the
air-conditioning system on or off. When the button
is pressed, an indicator light will come on and the
system will begin to cool and dehumidify the air inside
of your vehicle. You may notice a slight change in
engine performance when the air conditioning
compressor shuts off and turns on again. This is
normal.
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 choose from to
clear fog or frost 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.
Turn the right knob clockwise or counterclockwise
to select one of the following modes:
-(Defog):This mode directs the air to the oor
outlets, windshield and side window outlets. The
recirculation button cannot be selected while in defog
mode.
1(Defrost):This mode directs most of the air to the
windshield and the side window outlets, with only a
little air directed to the oor outlets. The air conditioning
compressor may run to dehumidify the air to prevent
window fogging. The recirculation button cannot
be selected while in defrost mode. Do not drive the
vehicle until all the windows are clear.
3-22

Rear Window Defogger
Your vehicle may have this feature. The lines you see
on the rear window warm the glass.
<(Rear):Press this button to turn the rear window
defogger on or off. An indicator light in the button
will come on to let you know that the rear window
defogger is active. The rear window defogger will
automatically turn off approximately ten minutes after
the button is pressed.
If your vehicle is equipped with heated mirrors, this
button will activate them.
Notice:Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t 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 air outlets located in the center and on the side
of your instrument panel to direct the airow.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the vent setting to direct outside
air through your vehicle.Your vehicle’s ventilation system supplies outside air to
the inside of your vehicle when it is moving. With the
side windows closed, air will ow into the front air inlet
grilles, through the vehicle and out the air exhaust
valves.
Outside air will also enter the vehicle when the heater
or the air conditioning is running, unless you have
selected recirculation mode.
Operation Tips

Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the
fan knob all the way to the right for a few moments
before driving. This helps clear the intake ducts
of snow and moisture, and reduces the chance of
fogging the inside of your window.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
Adding outside equipment to the front of your
vehicle, such as hood-air deectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle.
3-23

Dual Automatic Climate Control
System
Your vehicle may have the dual automatic climate
control system. With this system you can control the
heating, cooling and ventilation for your vehicle.
When your vehicle is rst started and the climate control
system is on, or if the climate control system has
been turned on, the display will show the driver’s
temperature setting for ve seconds. Then it will show
the outside temperature.
Outside Air Temperature Display
A new outside temperature reading will be displayed if
the vehicle has been off for more than three hours. If the
vehicle has been off for less than three hours, the old
temperature reading may be displayed because
underhood heat is affecting the true outside temperature.
Since underhood heat can also affect the outside
temperature while the engine is running, it may take
several minutes of driving before the display updates to
the actual outside temperature.
OFF:Press this button to turn off the entire climate
control system. Outside air will still enter the vehicle, and
will be directed to the oor. Press the AUTO button,
the mode button, the fan arrows, or either temperature
knob to turn the system on.
MODE:Press this button to manually select the air
delivery mode to the oor, instrument panel, or
windshield outlets. The system will stay in the selected
mode until the mode button is pressed again or the
AUTO button is pressed.
