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 170
for more information.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
172

Fog Lamps
-(Fog Lamps):If your vehicle has 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.
Your ignition must be in 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. SeeInstrument Panel Cluster on page 194.
Press the exterior lamps button again to turn the
fog lamps off.
The ignition must be in 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 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
OFF and any door is opened.
173

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 231
for information on programming.
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.
175

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.
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 221.
176

The display is located
near the rear window
and can be seen
by looking over your
right shoulder.
The display has three color-coded lights. The
URPA lights are used to provide distance and
system information, along with beeps played out
the speakers.
How the System Works
When the shift lever is moved into REVERSE (R),
the rear display will briey illuminate to let you know
the display is operating correctly. URPA comes on
automatically when the shift lever is moved into
REVERSE (R). The system also does not work at a
reverse speed greater than 5 mph (8 km/h). To
remind you of this, the red light on the rear display
will ash.The system can be disabled using the Driver
Information Center (DIC). SeeDIC Controls and
Displays on page 212.
How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The rst time an
object is detected a single beep will sound. If an
object is detected at a REVERSE (R) speed
between 0 mph (0km/h) and 5 mph (8 km/h), the
following describes what will occur based on your
distance to a detected object located behind the
vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will be lit.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be lit.
At distances between 12 inches (0.3 m)
and 23 inches (0.6 m), all three lights
(amber/amber/red) will be lit.
At distances less than 12 inches (0.3 m), a
beeping sound will repeat for a short time and
all three lights (amber/amber/red) will be lit and
ashing.
179

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARK ASSIST
OFF will be displayed on the DIC and a red light will
be shown on the rear URPA display when the shift
lever is moved into REVERSE (R). This occurs
under the following conditions:
The driver disables the system. SeeDIC
Controls and Displays on page 212.
The parking brake pedal is pressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your
trunk during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next
drive, the system will return to normal operation
unless an object is detected when the vehicle is
shifted into REVERSE (R). If this occurs, URPA
assumes the object is still attached, so you will
have to wait until the vehicle is driven forward
above 15 mph (25 km/h) before URPA will
return to normal operation.
The ultrasonic sensors are not kept clean. So,
be sure to keep your vehicle’s rear bumper free
of mud, dirt, snow, ice, and slush. For cleaning
instructions, seeWashing Your Vehicle on
page 422. If the DIC still displays the PARK
ASSIST OFF message after cleaning the
bumper and driving forward at a speed of at
least 15 mph (25 km/h), see your dealer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
When URPA is disabled without driver action
and the driver attempts to turn URPA back on
using the Driver Information Center (DIC), the
PARK ASSIST ON option will not be selectable
if the necessary conditions stated above for
normal system operation are not met.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being sure to
check for other vehicles, obstructions and blind
spots.
180

For Driver Information Center messages related to
URPA, seeDIC Warnings and Messages on
page 221.
If the bumper is damaged, your URPA system
may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug in
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle may have up to three power outlets
depending on the type of front seat you have.
If your vehicle has front bucket seats with a center
console, you will nd two outlets inside the rear
storage compartment. An extra power outlet
can be found in the ashtray.
Your vehicle may have a small cap that must be
pulled down to access the accessory power outlet.
If it does, when not using the outlet be sure to
cover it with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always
turn off electrical equipment when not in use
and do not plug in equipment that exceeds the
maximum amperage rating.Certain electrical accessories may not be
compatible to the accessory power outlets and
could result in blown vehicle or adapter fuses. If
you experience a problem see your dealer for
additional information on the accessory power
outlets.
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 before adding electrical equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
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.

ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
To use the lighter, push the center all the way in
and let it go. When it is ready, the center will
pop back out by itself. Pull out the entire unit to
use it.
Notice:Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in
while it is heating.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling, and ventilation for your vehicle.
If your vehicle has the remote start feature and it is
activated, the climate control system will heat and
cool the inside of the vehicle, using the previous
system settings before the vehicle was turned off.
The rear window defogger will be turned on by the
climate control system when it is cold outside. If the
vehicle has heated seats, they will also turn on.
Cooled seats are not activated during a remote
