The system could also turn on the lamps 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 are 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 after the transmission
is shifted out of P (Park). Once the vehicle leaves the
garage, it takes about one minute for the automatic
headlamp system to change to DRL if it is light outside.
During that delay, the instrument panel cluster might
not be as bright as usual. Make sure the instrument
panel brightness control is in the full bright position.
If the vehicle is running and the automatic headlamp
system is already on, it can be turned off by turning
and releasing the headlamp control at the off position.
The automatic headlamp system stays off until you
turn and release the headlamp control at the off position
again. SeeHeadlamps on page 3-13.Fog Lamps
The fog lamp control is located on the turn
signal/multifunction lever.
Use the fog lamps for better vision in foggy or misty
conditions.
#:The band with this symbol is used to turn the fog
lamps on and off.
When the fog lamps are turned on, the parking lamps
also turn on. A message will also display on the DIC
when the fog lamps are turned on or off. SeeDriver
Information Center (DIC) on page 3-42.
To turn the fog lamps on or off, turn the fog lamp
band on the lever up to the dot and release it.
The band will return to its original position.
If the high-beam headlamps are turned on, the fog
lamps will turn off. They will turn back on again
when you switch back to low-beam headlamps.
When the Fog Lamps are turned on or off, a message
will appear on the Driver Information Center. SeeDIC
Warnings and Messages on page 3-45.
Some localities have laws that require the headlamps to
be on along with the fog lamps.

Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition. If the dome
override is off, these lights will stay on for a short period
of time and then will go out.
Reading Lamps
Press the indented part of the lenses on the reading
lamps located in the overhead console 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 3-45.

You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal.
@(Recirculation):Press to turn the recirculation
mode on or off. An indicator light comes on to show that
recirculation is on. This mode recirculates and helps
to quickly cool the air inside the vehicle. It can be used
to help prevent outside air and odors from entering
the vehicle. Recirculation mode can be used with vent
and bi-level modes, but it cannot be used with oor,
defog or defrost modes.
If recirculation mode is selected with oor, defog, or
defrost modes, the indicator ashes three times
and turns off to indicate the selection is not available.
The air conditioning compressor may also run while
in recirculation mode. This is normal and helps to
prevent window fogging.
If the weather is cold and damp, the system may cause
the windows to fog while using recirculation mode.
If the windows do start to fog, select defog or defrost
mode and increase fan speed.
Recirculation mode, if selected, will be cleared when the
engine is turned off.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press to turn the rear window defogger
on or off.
An indicator light comes on to show that the rear
window defogger is on.
The rear window defogger will turn off approximately
10 minutes after the button is pressed. If additional
warming time is needed, press the button again.
The heated mirrors will also come on when the rear
window defogger is turned on. SeeOutside Heated
Mirrors on page 2-34.
Notice:Do not use a razor blade or sharp object
to clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.

This message displays and a chime sounds if the
cooling system temperature gets hot. SeeEngine
Overheating on page 5-34for the proper course of
action. This message clears when the coolant
temperature drops to a safe operating temperature.
FRONT FOG LAMPS OFF
This message displays if the fog lamps are turned off.
The message clears after 10 seconds. If you turn on the
high-beam headlamps, the fog lamps also turn off
and this message appears on the DIC. The fog lamps
turn back on again when you switch back to low-beam
headlamps. SeeFog Lamps on page 3-15andTurn
Signal/Multifunction Lever on page 3-6for more
information.
FRONT FOG LAMPS ON
This message displays if the fog lamps are turned on.
The message clears after 10 seconds. SeeFog Lamps
on page 3-15andTurn Signal/Multifunction Lever on
page 3-6for more information.
FUEL LEVEL LOW
This message displays and a chime sounds if the fuel
level is low. Refuel as soon as possible. SeeLow
Fuel Warning Light on page 3-41,Filling the Tank on
page 5-8, andFuel on page 5-5for more information.
ICE POSSIBLE
This message may display if the outside temperature
reaches a level where ice could form on the roadway.
Adjust your driving accordingly. If the temperature
rises to a safe level, the message clears. This message
clears itself after 10 seconds, or you can manually
clear it from the DIC display.
KEY FOB # BATTERY LOW
This message displays if a Remote Keyless Entry (RKE)
transmitter battery is low. Replace the battery in the
transmitter. See “Battery Replacement” underRemote
Keyless Entry (RKE) System Operation on page 2-5.
LEFT REAR DOOR AJAR
This message displays and a chime sounds if the driver
side rear door is not fully closed. Stop and turn off
the vehicle, check the door for obstructions, and close
the door again. Check to see if the message still
appears on the DIC.
