Delayed Headlamps
The delayed headlamps feature provides a period
of exterior lighting as you leave the area around
your vehicle. The feature is activated when
the headlamps are on due to the automatic
headlamps control feature described previously in
this section, and when the ignition is turned off.
Your headlamps will then remain on until the
exterior lamps control is moved to the parking
lamps position or until the pre-selected delayed
headlamp lighting period has ended.
If you turn off the ignition with the headlamps
switch in the parking lamps or headlamps position,
the delayed headlamps cycle will not occur.
To disable the delayed headlamps feature or
change the time of delay, seeDIC Vehicle
Customization on page 208.
Daytime Running Lamps (DRL)/
Automatic Headlamp System
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles rst sold in Canada.
A light sensor on top of the instrument panel
makes the DRL work, so be sure it is not covered.
The DRL system’s automatic headlamp control
will make the low-beam headlamps come on at a
reduced brightness when the following conditions
are met:
The ignition is in the ON position.
The exterior lamps control is in AUTO.
The engine is running.
When the DRL are on, only the low-beam
headlamps, at a reduced level of brightness, will
be on. The headlamps, taillamps, sidemarker, and
other lamps will not be on. The instrument
panel and cluster will also not be lit.
162

When it is dark enough outside, the low-beam
headlamps will turn off and the headlamps
and parking lamps will turn on. The other lamps
that come on with the headlamps will also
come on.
When it is bright enough outside, the headlamps
will go off and the DRL will come on.
As with any vehicle, you should turn on the
regular headlamp system when it is needed.
Fog Lamps
-(Fog Lamps):If your vehicle has fog lamps,
the control is located on the exterior lamps
control. The exterior lamps control is located on
the instrument panel to the left of the steering
column.
The ignition must be in the ON position for the fog
lamps to come on.
To turn the fog lamps on, press the exterior lamps
button. A light will come on in the instrument
panel cluster. Press the exterior lamps button
again to turn the fog lamps off.When the headlamps are changed to high-beam,
the fog lamps also go off.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Instrument Panel Brightness
D(Instrument Panel Brightness):The knob
with this symbol on it is located next to the exterior
lamps control. Push the knob in all the way until
it pops out and then turn the knob clockwise
to brighten or counterclockwise to dim the lights.
Push the knob back in when nished.
Courtesy Lamps
When a door is opened, the courtesy lamps
automatically come on. They make it easy for you
to enter and leave your vehicle. You can also
manually turn these lamps on by fully turning the
instrument panel brightness control clockwise.
The reading lamps, located on the rearview
mirror, can be turned on or off independent of the
automatic courtesy lamps, when the doors
are closed.
163

Dome Lamp
The dome lamp will come on when you open a
door. You can also turn this lamp on by turning the
instrument panel brightness control clockwise.
Entry Lighting
Your vehicle may have courtesy lamps that will
come on and stay on for a set time whenever the
unlock symbol is pressed on the Remote
Keyless Entry (RKE) Transmitter, if the vehicle
has one.
If a door is opened, the lamps will stay on while it
is open and then turn off automatically about
25 seconds after the door is closed. If the unlock
symbol is pressed and you do not open a
door, the lamps will turn off after about
20 seconds.
Entry lighting includes a feature called theater
dimming. With theater dimming, the lamps do not
turn off at the end of the delay time. Instead,
they slowly dim after the delay time until they go
out. The delay time is canceled if you turn the
ignition key to ON or press the power door
lock switch. The lamps will dim right away.When the ignition is on, illuminated entry is
inactive, which means the courtesy lamps will not
come on unless a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. Immediately after all the doors have been
closed, the delayed entry lighting feature will
continue to work until one of the following occurs:
The ignition is in ON.
The doors are locked.
An illumination period of 25 seconds has
elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on because a
door is open.
164

Delayed Exit Lighting
This feature illuminates the interior for a period of
time after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to
work. When the key is removed, interior illumination
will activate and remain on until one of the following
occurs:
The ignition is in ON.
The power door locks are activated.
An illumination period of 20 seconds has
elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on because a
door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. It automatically prohibits the
dimming of the instrument panel displays during
the daylight while the headlamps are on so
that you will still be able to see the displays.
Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on
and 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 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.
165

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,
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 or
Service Battery Charging System.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 199.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until
one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will timeout after 10 minutes, if they
are manually turned on before the ignition is off.

Accessory Power Outlet(s)
Your vehicle has three 12-volt outlets which can be
used to plug in electrical equipment such as a
cellular telephone, a compact disc player, etc.
On vehicles with a center console, one outlet is
located at the rear of the console in the bottom of
the bin and two outlets are located at the front
of the console bin under the instrument panel.
Lift the cover to access the outlet. Close the cover
when not using the outlet.
On vehicles without a center console, two are
located under the climate controls and another
outlet for the rear seat passengers is at the rear
of the center front seat. Remove the rubber
cover to access the outlets. When not using
the outlet, make sure the cover is on it.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.Certain accessory plugs may not be compatible to
the accessory power outlet and could result in
blown vehicle and adapter fuses. If you experience
a problem, see your dealer for additional
information on the power accessory plugs.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should.
The repairs would not be covered by your
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. Check with your dealer
before adding electrical equipment, and never use
anything that exceeds the maximum amperage
rating of 20 amps.
Notice:Improper use of the power outlet can
cause damage not covered by your 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.
