•Taillamps
•License Plate Lamps
If the headlamps are turned on while the vehicle is on,
the headlamps turn off automatically 10 minutes
after the ignition is turned off. If the headlamps are
turned on while the vehicle is off, the headlamps will
continue to stay on. To prevent the battery from
being drained, turn the control to the
Oposition.A warning chime sounds if the driver door is opened
while the ignition switch is off and the headlamps are on.
To change the headlamps from low beam to high
beam, push the turn signal/multifunction lever toward
the instrument panel.
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 3-59.

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.
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.
3-15

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 3-16.
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.
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 door
is opened.
3-16

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
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.
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.

Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briefly when the engine is started
to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.
