Wiper Activated Headlamps
This feature turns on the low-beam headlamps,
instrument panel cluster backlighting and taillamps
when the windshield wipers have been in use for about
six seconds.
If the wiper activated headlamps are on and the ignition
switch is turned to C (RUN), the wiper activated
headlamps will continue. When you turn the key to
A (OFF), the wiper activated headlamps will immediately
turn off. The wiper activated headlamps will also turn
off if you turn off the windshield wipers.
Headlamps on Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver’s door, you will hear a continuous
warning chime. The chime will turn off when the lamps
are turned off.
Daytime Running Lamps (DRL)
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 monitors
the exterior light level for the operation of DRL, so
be sure it is not covered.
The DRL system will make your low-beam headlamps
turn on at reduced brightness in daylight when the
following conditions are met:
The ignition is on.
The exterior lamp button for the headlamps is off.
The automatic transaxle is not in PARK (P).
When the DRL are on, only your low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps will not be on.
When it is dark enough outside, your low-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is
bright enough outside, the regular lamps will go off, and
your low-beam headlamps change to the reduced
brightness of DRL.
To turn off all exterior lighting at night when you are
parked, turn the exterior lamp control to the off position.
The exterior lamps will turn back on automatically
when you move the transaxle out of PARK (P).
SeeExterior Lamps on page 3-14for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Fog Lamps
-(Fog Lamps):If your vehicle is equipped with fog
lamps, it is located on the exterior lamps control.
The exterior lamps control is located on the instrument
panel to the left of the steering column.
Your ignition must be in C (RUN) for the fog lamps to
illuminate.
To turn the fog lamps on, press the exterior lamps button.
A light will come on in the instrument panel cluster to let
you know that the fog lamps are on. Press the exterior
lamps button again to turn the fog lamps off.
The ignition must be in C (RUN) and the parking lamps
must be on for your fog lamps to work.
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
If your vehicle has this feature, the cornering lamps
come on when: the headlamps or parking lamps are on,
the vehicle is not in PARK (P), 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 A (OFF) and a door has been opened.
This protects against draining the battery in case you
have accidentally left the headlamps or parking
lamps on. If you need to leave the lamps on for more
than 10 minutes, use the manual control to turn the
lamps back on after the ignition is turned to A (OFF) and
any door is opened. To delay the lamps from turning
off, seeDIC Vehicle Customization on page 3-65.

Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps go on. They make it easy for you to enter
and leave the vehicle. Turn these lamps on manually
by turning the instrument panel brightness control
completely clockwise.
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 C (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.

Front Reading Lamps
The front reading lamps, located on the headliner, are
turned on or off by pressing one of the buttons
located near each lamp.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher RPM setting than normal to make sure the
battery charges. High electrical loads may occur when
several of the following are on: headlamps, high beams,
rear window defogger, fan at high speed, heated
seats (if equipped), and engine cooling fans.
If your vehicle’s battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats, and heated mirrors will be
disabled and the DIC will display SERVICE BATTERY
CHARGING SYSTEM. This can happen either under
long periods of idling or low speed driving with high
electrical loading, or in the event of a charging system
fault. SeeDIC Warnings and Messages on page 3-56
for more information.
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.
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle is equipped, the Ultrasonic Rear Parking
Assist (URPA) system is designed to help you park
while in REVERSE (R). It operates only at speeds less
than 5 mph (8 km/h). URPA helps make parking
easier and helps you avoid colliding with objects such
as parked vehicles. The URPA system detects
objects that are close to the rear of the vehicle which
are at least 10 inches (25.4 cm) off the ground and
below hood or trunk level. The system detects objects
up to 8 feet (2.5 m) behind your vehicle. URPA
determines how close these objects are from your
bumper within this area. Ultrasonic sensors on the rear
bumper are used to detect the distance to the object.

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog from
your windshield, defog and defrost.
W(Floor/Defog):Use this mode to clear the windows
of fog or moisture and to warm the passengers.
Turning the control to this mode directs approximately
half of the air to the oor outlets and the remaining air
is directed to the side window outlets and to the
windshield. When you select this mode, the system
turns off recirculation and runs the air-conditioning
compressor unless the outside temperature is at or
below freezing. The recirculation mode cannot be
selected while in the oor/defog mode.
0(Defrost):Use this mode to remove fog or frost
from the windshield more quickly. Turning the control to
this mode directs most of the air to the windshield
and the side window outlets. In this mode, the system
will automatically turn off recirculation and run the
air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode. Do not drive
the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press this button to turn the rear
window defogger on or off. An indicator light below
the button will come on to let you know that the rear
window defogger is activated. Be sure to clear as much
snow from the rear window as possible.
The rear window defogger will only work when the
ignition is in C (RUN). The rear window defogger will
stay on for approximately 20 minutes after the button is
pressed if you are traveling at slower vehicle speeds.
At higher vehicle speeds the rear window defogger may
stay on continuously. If turned on again, the defogger
will only run for approximately 10 minutes before turning
off. The defogger can be turned off by pressing the
button again, by turning the ignition to B (ACCESSORY)
or C (RUN), or by turning off the engine.
The heated outside rearview mirrors will heat to help clear
fog or frost from the surface of the mirror when the rear
