Headlamps on Reminder
If a door is open, a reminder chime sounds 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 Driver Information Center (DIC). See “Exit Lighting”
underDIC Vehicle Customization on page 3-57.
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 first sold in Canada.The DRL system comes on in daylight when the
following conditions are met:
•The ignition is on.
•The exterior lamps control is in the AUTO position.
•The shift lever is not in P (Park).
•The light sensor determines it is daytime.
When the DRL are on, the taillamps, sidemarker,
instrument panel and other lamps will not be on.
The automatic headlamp system automatically switches
from DRL to the headlamps depending on the darkness
of the surroundings.
To turn off the DRL, turn the exterior lamp control to the
off position and then release it. For vehicles first sold
in Canada, the transmission must be in the P (Park)
position, before the DRL can be turned off.
3-14

Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, the automatic headlamp system turns
on the headlamps, along with 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 first 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 the 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 or tunnel.
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 is only 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 comes on immediately. Once the
vehicle leaves the garage, it takes approximately
30 seconds 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 3-15.
Instrument Panel Brightness
The knob for this feature is located next to the exterior
lamps control.
D(Instrument Panel Lights):Push knob to extend
and then turn clockwise or counterclockwise to brighten
or dim the instrument panel lights and the radio display.
This only works if the headlamps or parking lamps are on.
To turn on the dome lamps, with the vehicle doors
closed, turn the knob all the way clockwise.
3-15

Dome Lamps
The dome lamps come on when any door is opened.
They turn off after all the doors are closed.
The dome lamps can also be turned on by turning
the instrument panel brightness knob, located on the
instrument panel to the left of the steering column,
clockwise to the farthest position. In this position, the
dome lamps 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.
The dome lamp override sets the dome lamps to remain
off or come on automatically when a door is opened.
E(Dome Lamp Override):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

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
For vehicles with reading lamps, press the button
located next to each lamp to turn it on or off.
The vehicle may also have reading lamps in other
locations. The lamps cannot be adjusted.
3-16

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 put the charge back in. When the
state of charge is high, the voltage is lowered slightly to
prevent overcharging. If the vehicle has a voltmeter gage
or 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 loads are on: headlamps, high beams, rear
window defogger, climate control fan at high speed,
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.
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.
3-17

Accessory Power Outlet(s)
The accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular phone.
The vehicle may have two accessory power outlets
located on the instrument panel.
To use the accessory power outlet lift the cover. The
spring cap cover closes by itself when the outlet is empty.
Certain power accessory plugs may not be compatible
to the accessory power outlet 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.
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.
When adding electrical equipment, be sure to follow
the proper installation instructions included with the
equipment.
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.

in the ashtray.
To remove the ashtray, pull it out from the console
or from the slide out door. To reinstall the ashtray,
slide it back to the original position.
To use the cigarette lighter, if the vehicle has one, push
it in all the way, and let go. When it is ready for use,
it will pop back out by itself.
Do not use the lighter to plug in accessory devices.
Use the power outlets provided.
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
