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 dim.
Your vehicle is equipped with a headlamp off delay,
which will keep the headlamps on for a short time after
the ignition is turned
off. For more information see
DIC Operation and Displays on page 3-43.
Your vehicle has a light sensor located on the top of the
instrument panel in the defroster grille. Be sure it is
not covered, or the system will be on whenever
the ignition is on.
The system may also turn on your 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 sees a change in lighting lasting
longer than the delay. 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. See
“Instrument Panel Brightness Control’’ under
Interior
Lamps on page
3-15.
To idle your vehicle with the automatic headlamp
system off, turn the control to the
off position.
You may be able to turn off your automatic headlamp
system. See Daytime Running Lamps (DRL) later in this
section for more information.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the Driver
lnforrnation Center. See
Driver lnforrnation Center @IC)
on page
3-43
As with any vehicle, you should turn on the regular
headlamps
if you need them.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your
ignition is off, in LOCK, ACCESSORY, or your door is
open. To disable the chime, turn the light
off, then
back on.
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
3-1 2

Climate Controls
Dual Automatic Climate Control
System
Your vehicle may have the optional dual automatic
climate control system. With this system you can control
the heating, cooling and ventilation for your vehicle.
If your vehicle is equipped with the dual automatic
climate control system, memory seats, and memory
mirrors, you can store and recall the climate control
settings for temperature, air delivery mode, and
fan speed for two different drivers. The personal choice
settings recalled are determined by the transmitter
used to enter the vehicle. After the button with the
unlock symbol on a remote keyless entry transmitter
is pressed, the climate control will adjust to the last
settings of the identified driver. The settings can also be
changed by pressing one of the memory buttons
(1 or 2) located on the driver’s door. When adjustments
are made, the new settings are automatically saved
for that driver.
A 8fj? v (Fan): Press this button to increase or
decrease the fan speed.
0 (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 floor. This direction can be changed
by pressing the mode button. The temperature can also
be adjusted using either temperature knob. Press the up
or down arrows on the fan switch, the defrost button, the
AUTO button, or the air conditioning button to turn the
system on when it is
off.
,% 4d (Mode): Press this button to manually select the air
delivery mode to the floor, panel, or windshield outlets.
This system will stay in the selected mode until the mode
button is pressed again, or the AUTO button, defrost
button, or the off button is pressed. Air delivery mode can
be adjusted while the system is off. A five second status
display will indicate the current mode.
3-1 8

Display: In the full AUTO mode, the automatic dual
climate control system display will show the driver set
temperature and an arrow pointing to the driver’s side. An
arrow pointing to the passenger’s side will display
if both
sides are set to the same temperature.
If the temperature
settings are not the same, the opposite side temperature
setting will be displayed for an additional five seconds.
During the five second status display the current mode
and blower speed will be displayed.
Driver’s Side Temperature Knob: Turn this knob
clockwise or counterclockwise to manually raise or lower
the temperature on the driver’s side of the vehicle.
The display will show the temperature setting decreasing
or increasing and an arrow pointing to the driver. The
temperature can be adjusted even
if the system is
turned
off. If the passenger’s set temperature has not
been adjusted this knob controls both the driver’s
and passenger’s air temperature. The temperature to
the rear seat area is controlled by using this knob.
Passenger’s Side Temperature Knob: Turn this knob
clockwise or counterclockwise to manually raise or
lower the temperature on the passenger’s side of the
vehicle. The display will show the temperature
setting decreasing or increasing and an arrow pointing
to the passenger. The temperature can be adjusted
even
if the system is turned off. Once this knob is used,
the passenger’s temperature will remain independent
of the driver’s until the AUTO button is pressed and held
for approximately four seconds.
Automatic Operation
AUTO (Automatic): When automatic operation is
active the system will control the inside temperature, the
air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current driver’s set temperature,
delivery mode and fan speed. Press the AUTO
button again within five seconds to display
the passenger’s set temperature.
If the driver and passenger’s temperature settings
are not the same, the opposite side temperature
setting will be displayed for an additional five
seconds. To make the passenger’s temperature the
same as the driver’s press and hold the AUTO
button for approximately four seconds.
When auto is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will run
when the outside temperature is over approximately
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down your vehicle. The light on the
button will illuminate in recirculation.

2. Set the driver’s and passenger’s temperature.
To find your comfort setting, start with a
74°F
(23°C) temperature setting and allow about
20 minutes for the system to regulate. Turn the
driver’s or passenger’s side temperature knob
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 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.
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.
Manual Operation
To change the current setting, select one of the
following:
A 8f? v (Fan): This button allows you to manually
adjust the fan speed. Press the up arrow
to increase fan
speed and the down arrow
to decrease fan speed.
4d (Mode): Press this button to manually change the
direction of the airflow in your vehicle; keep pressing the
button until the desired mode appears on the display.
If you press the mode button
to select an air delivery
mode, the display will change
to show you the selected
air mode delivery. The display will then show the
current status of the system. When the system is turned
off, the display will go blank after displaying the
current status
of the system.
f;’ (Vent): This mode directs air to the instrument
panel vents.
+2 (Bi-Level): This mode directs half of the air to the
instrument panel vents, then directs the remaining air
to
the floor vents. A little air is directed toward the
windshield and the side window vents. Cooler air is
directed
to the upper vents and warmer air to the floor
vents.
3-20

(ri (Floor): This mode directs most of the air to the
floor vents. Some air also comes out of the defroster and
side window vents. Use this mode to send air to the
rear of the vehicle. Keep the area under the front seats
free of objects that could obstruct airflow to the rear
of the vehicle. The recirculation button cannot be
selected in the floor mode.
(Recirculation): Press this button to turn the
recirculation mode on or
off. The recirculation mode is
used to limit the amount of outside air entering your
vehicle. This is helpful when you are trying to prevent
outside odors and/or dust from entering your vehicle, or
to help cool the air inside of your vehicle more quickly.
When this mode is on, inside air will recirculate
throughout your vehicle. When this button is pressed,
an indicator light in the button will also come on to
let you know that it is activated.
If you select recirculation while in defrost, defog, or
floor, the light on the button will flash and go out to let
you know this is not allowed. This is to prevent
windshield fogging.
If the weather is cold and damp, the system may cause
the windows to fog while using the recirculation
mode.
If the windows do start to fog, select defog or
front defrost mode
a NC (Air Conditioning): Press this button to
manually turn the air-conditioning system on or
off.
When the system is selected, or in AUTO mode
the system will automatically begin to cool and
dehumidify the air inside
of your vehicle.
If you select air conditioning off while in front defrost, or
defog mode the air conditioning
off symbol will flash
to let you know this is not allowed.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts
off and
turns
on again. This is normal.
%k (Air Conditioning Off): When you turn the air
conditioning
off, this symbol will appear on the display.
When the air conditioning is selected or in AUTO
mode, the system will run the air conditioning
automatically.
