When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release. For
vehicles rst sold in Canada, the transmission must be
in the PARK (P) position, before the DRL lamps can
be turned off.
Automatic Headlamp System
When it is dark enough outside, the automatic headlamp
system will turn on the headlamps at the normal
brightness, along with the taillamps, sidemarker, parking
lamps, and the instrument panel lights. The radio
lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then release
it. For vehicles rst sold in Canada, the transmission
must be in the PARK (P) position, before the automatic
headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel in the defroster grille that regulates
when the automatic headlamps turn on. Be sure it is not
covered, or the headlamps will come on whenever
the ignition is on.
The system may also turn on the 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 detects a change in lighting lasting
longer than the delay.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once
the vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is bright enough outside. During that
delay, the instrument panel cluster may not be as
bright as usual. Make sure the instrument panel
brightness control is in the full bright position. See
Instrument Panel Brightness on page 3-19.
To idle the vehicle with the automatic headlamp system
off, turn the control to the off position.
The headlamps will also stay on after you exit the
vehicle. This feature can be programmed using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 3-64.
The regular headlamp system can be turned on when
needed.

Climate Controls
Dual Automatic Climate Control
System
The heating, cooling, and ventilation in your vehicle can
be controlled with this system. Your vehicle also has
a ow-through ventilation system described later in this
section.
Different climate control settings can be selected for the
driver and passengers.
Driver’s Side Temperature Control
The driver’s side temperature buttons are used to adjust
the temperature of the air coming through the system on
the driver’s side. The temperature can be adjusted even if
the system is turned off. This is possible since outside air
will always ow through the system as the vehicle is
moving forward unless it is set to recirculation mode. See
“Recirculation” later in this section.
Press the + or−buttons to increase or decrease the
cabin temperature. The driver side temperature display
will show the temperature setting decreasing or
increasing.
Passenger’s Side Temperature Control
The passenger’s temperature buttons can be used to
change the temperature of the air coming through
the system on the passenger’s side of the vehicle. The
temperature can be adjusted even if the system is
turned off. This is possible since outside air will always
ow through the system as the vehicle is moving
forward unless it is set to recirculation mode. See
“Recirculation” later in this section.
Press the + or−buttons to increase or decrease the
cabin temperature. The passenger side display will show
the temperature setting decreasing or increasing.
3-23

The passenger’s temperature setting can be set to match
the driver’s temperature setting by pressing the PASS
button and turning off the PASS indicator. When the
passenger’s temperature setting is set different than the
driver’s setting, the indicator on the PASS button will
illuminate and both the driver’s side and passenger’s side
temperature displays will be shown.
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 temperature(s) and AUTO will
be lit on the display. The current delivery mode and
fan speed will also be displayed for approximately
5 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 about
40°F (4°C). The air inlet will normally be set to
outside air.If it is hot outside, the air inlet may automatically
switch to recirculate inside air to help quickly
cool down the vehicle. The light on the button will
illuminate in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F (23°C)
temperature setting and allow about 20 minutes
for the system to regulate. Use the driver’s or
passenger’s temperature buttons 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 solar 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 the headlamps. For more information on
the solar sensor, see “Sensors” later in this section.
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.
