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.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
The DRL system makes either the
low-beam headlamps come on at a
reduced brightness or the DRL
lights, for vehicles with High
Intensity Discharge (HID)
headlamps when the following
conditions are met:
.The ignition is in the ON/RUN
position.
.The exterior lamps control is
in AUTO.
.The engine is running.When the DRL are on, the regular
headlamps, taillamps, sidemarker,
and other lamps will not be on. The
instrument panel and cluster will
also not be lit.
For vehicles with HID headlamps,
if the DRL are on and the left or
right turn signal lamp is turned on,
the left or right DRL will go off.
The headlamps automatically
change from DRL to the regular
headlamps depending on the
darkness of the surroundings. 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.
The regular headlamp system
should be turned on when needed.
Do not cover the light sensor on top
of the instrument panel because it
works with the DRL.
Hazard Warning Flashers
|
Hazard Warning Flasher:
Press this button located on the
instrument panel below the audio
system, to make the front and rear
turn signal lamps flash on and off.
This warns others that you are
having trouble. Press again to turn
the flashers off.
The turn signals do not work while
the hazard warning flashers are on.

6-4 Lighting
Turn and Lane-Change
Signals
An arrow on the instrument panel
cluster flashes in the direction of the
turn or lane change.
Move the lever all the way up or
down to signal a turn.Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The lever returns to its starting
position whenever it is released.
If after signaling a turn or lane
change the arrow flashes rapidly or
does not come on, a signal bulb
might be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.
See
Fuses and Circuit Breakerson
page 10‑31.
Turn Signal On Chime
If either one of the turn signals are
left on and the vehicle has been
driven more than 3/4 mile (1.2 km), a
chime will sound.
Fog Lamps
Use the fog lamps for better vision
in foggy or misty conditions.
The fog lamps button is on the
exterior lamps control 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 when the
fog lamps are in use. The ignition
must be on for the fog lamps
to work.
When the headlamps are changed
to high-beam, the fog lamps turn off.
The fog lamps come back on again
when the high-beam headlamps are
turned off.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.

Courtesy Lamps
The courtesy lamps automatically
come on when a door is opened.
The lamps can also be turned on

Lighting Features
Entry Lighting
For vehicles with courtesy lamps,
they 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 stay
on while it is open and then turn off
automatically about 20 seconds
after the door is closed. If the unlock
symbol is pressed and no door is
opened, the lamps 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 and then
go out. The delay time is canceled if
the ignition key is turned to ON/RUN
or the power door lock switch is
pressed. 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
continues to work until one of the
following occurs:
.The ignition is in ON/RUN.
.The doors are locked.
.An illumination period of about
25 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period is canceled and
the interior lamps remain on.
Delayed Exit Lighting
Delayed exit lighting 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
activates and remains on until one
of the following occurs:
.The ignition is in ON/RUN.
.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
This feature automatically prohibits
the dimming of the instrument panel
displays in daylight while the
headlamps are on so that the
displays are still able to be seen.
Battery Load
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 thevoltage 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, wheneverneeded. 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 one of these messages displays, it
is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) (With DIC Buttons)
on
page 5‑23or Driver Information
Center (DIC) (Without DIC Buttons)
on page 5‑28.

6-8 Lighting
Battery Power Protection
This feature helps 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
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 while the ignition is on
or off.
