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 are only
affected when the light sensor sees a change in
lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system comes on after the
transmission is shifted out of PARK (P). 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, the
instrument panel cluster might not be as bright as
usual. Make sure the instrument panel brightness
control is in the full bright position.
If the vehicle is running and the automatic
headlamp system is already on, it can be turned
off by turning and releasing the headlamp
control at the off position. The automatic headlamp
system stays off until you turn and release the
headlamp control at the off position again.
SeeHeadlamps on page 162.Fog Lamps
Use the fog lamps for better vision in foggy or
misty conditions. The ignition must be in RUN for
the fog lamps to work.
The fog lamp button
is located on the
instrument panel to
the right of the exterior
lamps knob.
Press the button to turn the fog lamps on.
Press the button again to turn them off. A light
glows near the button while the fog lamps are on.
Fog lamps turn off whenever the high-beam
headlamps are on.
Some localities have laws that require the
headlamps to be on along with the fog lamps.

@(Recirculation):Press this button to turn
recirculation mode on or off. When this button is
pressed, an indicator light in the button will
also come on to let you know that it is activated.
Recirculation mode is used to recirculate the
air inside of your vehicle. 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. Recirculation mode can
be used with vent and bi-level modes, but it
cannot be used with oor, defog or defrost modes.
You may also notice that the air conditioning
compressor will run while in recirculation mode.
This is normal and will help to prevent fogging.
If the weather is cold and damp, the system may
cause the windows to fog while using recirculation
mode. If the windows do start to fog, select
defog or defrost mode and increase fan speed.
Recirculation mode, if selected, will be cleared
when the engine is turned off.#A/C (Air Conditioning):Press this button to
manually turn the air conditioning system on or off.
When the system is on, the system will
automatically begin to cool and dehumidify the air
inside of your vehicle. The air conditioning
symbol will appear on the display when the air
conditioning is on and will turn off when the
air conditioning is off.
If you select turn the air conditioning off while in
front defrost or defog mode, the air conditioning
symbol will turn off, however, the A/C compressor
will remain on to help de-humidify the air inside
the vehicle. If one of the other modes is selected
the compressor will then turn the A/C off until it
is selected again or the AUTO button is pressed.
To avoid fogging the inside glass on rainy and
humid days at temperature above freezing,
press the air-conditioning button to run the air
conditioning compressor. Also, it is best to avoid
the use of recirculation mode except when
maximum air conditioning performance is needed
or for short times to avoid exterior odors.
You may notice a slight change in engine
performance when the air-conditioning compressor
shuts off and turns on again. This is normal.
173
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. You can use
either defog or front defrost to clear fog or frost
from your windshield.
-(Defog):Use this setting to clear the windows
of fog or moisture. This setting will deliver air
to the oor and windshield outlets.
0(Front Defrost):Press the front defrost button
to clear the windshield and side windows of
frost or fog quickly. The system will automatically
control the fan speed if you select defrost from
AUTO mode. If the outside temperature is
40°F (4°C) or warmer, your air conditioning
compressor will automatically run to help
dehumidify the air and dry the windshield. 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 from the rear window.
<(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
activated.
The rear window defogger will turn off
approximately 10 minutes after the button is
pressed. If you need additional warming time,
press the button again.
If equipped, your heated mirrors will also come on
when you press this button.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
