Fog Lamps
For vehicles with fog lamps, the button is located on
the exterior lamps control. The exterior lamps control is
located on the instrument panel to the left of the steering
column.
#(Fog Lamps):Press the exterior lamps button
to turn the fog lamps on or off. A light comes on in the
instrument panel cluster to show that the fog lamps
are on. SeeInstrument Panel Cluster on page 3-33.
The ignition must be in the ON/RUN position and
the parking lamps must be on for the fog lamps to
illuminate.
The fog lamps will go off while you change to high-beam
headlamps.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Cornering Lamps
For vehicles with this feature, the cornering lamps come
on when: the headlamps or parking lamps are on, the
vehicle is not in P (Park), and you signal a turn with
the turn signal/multifunction lever. They provide
more light for cornering.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off about 10 minutes after the ignition is
turned to LOCK/OFF and a door has been opened. This
protects against draining the battery if the headlamps or
parking lamps are accidentally left on. If you need to
leave the lamps on for more than 10 minutes, use the
exterior lamp control to turn the lamps back on after the
ignition is turned to LOCK/OFF and any door is opened.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel lights.
The knob for this control is located next to the exterior
lamps control.
Push the knob in and release when it pops out.
Turn the knob clockwise to increase the brightness
of the instrument panel lights and counter clockwise to
decrease the brightness. Turning the knob completely
clockwise to the detent will turn on the courtesy lamps.

Courtesy Lamps
When any door is opened, several lamps turn on
making it easier for you to enter and exit the vehicle.
Turn the instrument panel brightness control completely
clockwise to manually turn on these lamps.
Entry Lighting
If it is dark enough outside when you press the unlock
button on the remote keyless entry transmitter, the
interior courtesy lamps will turn on and stay on for about
40 seconds. The lamps can be turned off immediately by
pressing the lock button on the remote keyless entry
transmitter, turning the ignition key to ON/RUN or
activating the power door locks.
Delayed Entry Lighting
The interior lamps will turn on if you open the door when
it is dark enough outside. When you close the door with
the ignition off, the interior lamps will stay on for up to
25 seconds or until the ignition is turned to an on position.
When the lamps turn off as a result of the 25 second timer
or the ignition switch being turned on, the lighting will
deactivate by way of the theater dimming effect. Locking
the doors will override the delayed entry lighting feature
and the lamps will turn off right away.
Theater Dimming
This feature allows for a three to ve second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and stay
on for about 25 seconds. This will give you time to nd
the door pull handle or lock switches. Once the key is
inserted into the ignition, the exit lighting will be cancelled
and the lighting will fade out.
Perimeter Lighting
If it is dark enough outside when the unlock button on
the remote keyless entry transmitter is pressed, the
DRL, parking lamps and back-up lamps will come on.
This feature can be programmed on for various amounts
of time in seconds for each transmitter.
SeeDIC Vehicle Customization on page 3-66for
information on programming.
Front Reading Lamps
The front reading lamps are located on the headliner.
Press the button near each lamp to turn them on or off.

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.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, or garage door
opener. When the ignition is turned off, the power to
these features will automatically turn off after 10 minutes.
Power will be restored for an additional 10 minutes if any
door is opened, the trunk is opened or the courtesy lamp
switch is turned on.
