When the headlamps are turned on while the vehicle is
on, the headlamps will turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the vehicle is off, the headlamps will stay
on for 10 minutes before automatically turning off to
prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp on
position to make the headlamps stay on for an additional
10 minutes.
Headlamps on Reminder
If a door is open, a reminder chime will sound when the
headlamps or parking lamps are manually turned on and
the key is out of the ignition. To turn off the chime, turn
the headlamp switch to off or AUTO and then back on,
or close and re-open the door. In the AUTO mode, the
headlamps turn off once the ignition is in LOCK/OFF or
may remain on until the headlamp delay ends (if enabled
in the DIC). See “Exit Lighting” underDIC Vehicle
Customization on page 3-64.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in P (Park).
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, instrument panel lights,
and other lamps will not be on.
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
P (Park) position, before the DRL lamps can be
turned off.
3-16

Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, the automatic headlamp system will
turn on the headlamps at the normal brightness along
with other lamps such as the taillamps, sidemarker,
parking lamps, roof marker 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.
For vehicles rst sold in Canada, the transmission must
be in the P (Park) position, before the automatic
headlamp system can be turned off.
The vehicle has a light sensor located on the top of
the instrument panel. Do not cover this sensor or
the system 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 sees 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 light 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. SeeInstrument Panel Brightness
on page 3-17.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel lights
and is located next to the exterior lamp control.
Push the knob to extend out and then it can be turned.
Turn the knob clockwise or counterclockwise to
brighten or dim the instrument panel lights. Turning
the knob to the farthest clockwise position turns on
the dome lamps.
3-17

Dome Lamps
The dome lamps come on when any door is opened
and turns off when all doors are closed.
The dome lamps can also be turned on by turning the
instrument panel brightness knob, located next to
the exterior lamps control, clockwise to the farthest
position. In this position, the dome lamps will remain
on whether a door is opened or closed.
Dome Lamp Override
The dome lamp override button is located next to the
exterior lamps control.
k(Dome Off):Press the button in and the dome
lamps remain off when a door is opened. Press
the button again to return it to the extended position so
that the dome lamps come on when a door is opened.
Entry/Exit Lighting
The vehicle has an illuminated entry/exit feature.
The dome lamps come on if the dome override button is
in the out position, when a door is opened or the key
is removed from the ignition.
Reading Lamps
There are reading lamps located in the overhead
console and on the DVD Rear Seat Entertainment (RSE)
system console, if equipped. Press the button located
next to each lamp to turn it on or off.
These lamps will also come on with the dome lamps.
3-18

Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly bring the charge back up. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up or down.
This is normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 3-56.
Battery Run-Down Protection
This feature shuts off the dome lamps if they are left
on for more than 10 minutes when the ignition is
in LOCK/OFF. This helps to prevent the battery
from running down.
3-19

Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone.
The vehicle may have one outlet located inside the
storage bin below the climate control system, one outlet
inside the center oor console and two outlets on the
rear of the center oor console.
The outlet located inside the storage bin below the
climate control system can only use equipment that
does not exceed 15 amperes.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always
turn off electrical equipment when not in use and
do not plug in equipment that exceeds the maximum
15 ampere rating.
There may also be an accessory power outlet located
in the rear of the vehicle near the liftgate. To use
an accessory power outlet, remove the protective cap.
When not in use, always cover the accessory power
outlet with the protective cap.If the vehicle is the SUT model, there is an accessory
power outlet in the rear cargo area on the passenger
side of the vehicle.
Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would
not be covered by the vehicle warranty. Do not use
equipment exceeding maximum amperage rating
of 20 amperes. Check with your dealer/retailer before
adding electrical equipment.
Certain power accessory plugs may not be compatible
to the accessory power outlets and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer/retailer for additional information on the
accessory power plugs.
The accessory power outlets are powered, even when
the ignition is in LOCK/OFF. Continuing to use power
outlets while the ignition is in LOCK/OFF may cause the
vehicle’s battery to run down.
Notice:Improper use of the power outlet can cause
damage not covered by the warranty. Do not hang
any type of accessory or accessory bracket from the
plug because the power outlets are designed for
accessory power plugs only.

Ashtray(s) and Cigarette Lighter
For vehicles with an ashtray, it is removable and ts
into the front cupholder. Pull up on the ashtray door to
open it.
Notice:If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage the vehicle. Never put ammable items
in the ashtray.
To remove the ashtray, pull it out from the console.
To reinstall the ashtray, slide it back to the original
position.
To use the cigarette lighter, if equipped, push it in all
the way, and let go. When it is ready, it will pop back
out by itself.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from
the heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold
a cigarette lighter in while it is heating.
Analog Clock

Driver and Passenger Side Temperature
Control
The driver and passenger side temperature buttons
are used to adjust the temperature of the air coming
through the system on the driver or passengers side
of the vehicle. The temperature can be adjusted even
if the system is turned off. This is possible since outside
air always ows 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 or passenger
side temperature display shows the temperature setting
decreasing or increasing.
The passenger temperature setting can be set to match
the driver temperature setting by pressing the PASS
button and turning off the PASS indicator. When the
passenger temperature setting is set different than
the driver’s setting, the indicator on the PASS button
illuminates and both the driver side and passenger
side temperature displays are 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 comes on in recirculation.
3-23

2. Set the driver and passenger 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 or passenger
temperature buttons to adjust the temperature setting
as necessary. If a temperature setting of 60°F (15°C)
is chosen, the system remains at the maximum
cooling setting. If a temperature setting of 90°F
(32°C) is chosen, the system remains at the
maximum heat setting. Choosing either maximum
setting will not cause the vehicle to heat or cool
any faster.
Do not 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.Manual Operation
DC(Fan Control):Press these buttons to increase or
decrease the fan speed.
Pressing either fan button while in automatic control
places the fan under manual control. The fan setting
remains displayed and the AUTO light turns off. The air
delivery mode remains under automatic control.
