Wiper Activated Headlamps
This feature, if equipped, will automatically
activate the headlamps and parking lamps after
the windshield wipers have been in use for
about 30 seconds and when all of the following
conditions are met.
The exterior lamp control is in AUTO.
The headlamps have not already been
activated by automatic lighting.
The automatic lighting feature has not been
disabled using the exterior lamp control.
SeeExterior Lamps on page 181for additional
information.
If the wipers are activated for over 30 seconds
and the exterior lamp control is in the parking
lamps position, or the automatic lighting feature
has been disabled using the exterior lamp control,
a HEADLAMPS SUGGESTED message will
appear on the Driver Information Center,
if equipped.
Headlamps on Reminder
If you turn the ignition to LOCK while leaving the
lamps on, you will hear a warning chime once
the driver’s door is opened.
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 will make front parking and
turn signal lamps come on in daylight when the
following conditions are met:
The ignition is on.
The exterior lamps control is off.
182

When the DRL are on, only your front turn signal
lamps will be on. Your instrument panel will
not be lit up.
When it is dark enough outside, the exterior lamps
will come on automatically. When it is bright
enough outside, the exterior lamps will turn off
and the DRL will turn on. Of course, you may still
turn on the headlamps any time you need to.
If you start your vehicle in a dark garage,
the automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately 30 seconds for the automatic
headlamp system to change to DRL if it is
light outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make
sure your instrument panel brightness control is
in the full bright position. SeeInstrument
Panel Brightness on page 183.
To idle your vehicle with the DRL and automatic
headlamps off, toggle the exterior lamp control
to off after starting the vehicle.
As with any vehicle, you should turn on the
regular headlamp system when you need it.Instrument Panel Brightness
The knob to adjust
the instrument panel
brightness is located
in the center of the
interior lamp controls.
Turn the knob clockwise to brighten the lights and
counterclockwise to dim them.

column.
R(Interior Lamp Override):Turn the outer
knob to this position to have your interior lamps
remain off while any door is open.
1(Door):Turn the outer knob to this position to
turn the interior lamps on while any door is open
and when the ignition key is removed from the
ignition.
+(Interior Lamps):Turn the outer knob to this
position to turn the interior lamps on.
Turn the inner knob to adjust the instrument panel
brightness, described earlier in this section.
Dome Lamp
The dome lamp is located in the headliner and has
two buttons to manually turn it on or off. The dome
lamp will come on each time you open a door,
unless you turn on the interior lamps override
feature. SeeInterior Lamps Control on page 184.
Entry Lighting
With entry lighting, the interior of your vehicle is
illuminated so that you can see inside before you
enter your vehicle. The lamps will come on for
20 seconds if you unlock your door using your key
or the remote keyless entry transmitter and the

Delayed Lighting
The delayed lighting feature will continue to
illuminate the interior for 20 seconds after all doors
have been closed, so that you can nd your
ignition and buckle your safety belt at night.
Delayed lighting will not occur while the ignition is
in RUN or ACCESSORY. After 20 seconds
have passed, the interior lamps will slowly fade
out. The lamps will fade out before the 20 seconds
have passed if you do one of the following:
Turn the ignition to RUN or ACCESSORY.
Lock all doors using the remote keyless entry
transmitter.
Lock all doors using the power door lock
switch or the key.
To turn the delayed lighting feature off or on,

Cargo Lamp
The cargo lamp is located in the rear of your
vehicle, above the liftgate opening, and does not
have a switch. The cargo lamp will come on
each time you open a door, unless you turn on the
interior lamps override. SeeInterior Lamps
Control on page 184.
Electric Power Management
This vehicle has Electric Power Management
(EPM), an advanced control system. It estimates
the battery’s temperature and state of charge
and 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, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
186

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 Battery
Voltage Low. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible.Battery Run-Down Protection
Your vehicle has a feature to help prevent you
from draining the battery, in case you accidentally
leave the interior lamps on. If you leave any
interior lamps on while the ignition is in lock or off,
they will automatically turn off after 10 minutes.
The lamps will not come back on again until
you do one of the following:
Turn the ignition to RUN or ACCESSORY
Open a closed door, or close and reopen
a door.
Turn the interior lamps on if they are in the
door or override position.
Turn the interior lamps to the door or override
position and then to on again if the interior
lamp control is in the on position.
If your vehicle has less than 15 miles (25 km)
on the odometer, the battery saver will turn off
the lamps after only three minutes.
187

Overhead Console Switchbank
The overhead console switchbank is located in the
overhead console. This switchbank may include
the following:
Power Sliding Door(s)/Override Switch(es).
SeePower Sliding Door (PSD) on page 112.
Power Rear Quarter Windows. SeePower
Rear Quarter Windows on page 123.
Ultrasonic Rear Parking Assist (URPA)
Disable Switch. SeeUltrasonic Rear Parking
Assist (URPA) on page 188.
If your vehicle does not have some of these
options, there will be a blank.
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle is equipped with the Ultrasonic
Rear Parking Assist (URPA) system, it is
designed to help you park, while the vehicle is
in REVERSE (R). It operates only at very
low speeds, less than 3 mph (5 km/h). URPA can
help make parking easier and to help you avoid
colliding with objects such as parked vehicles.
The URPA system can detect objects up to 5 feet
(1.5 m) behind the vehicle, and tell you how
close these objects are from your rear bumper.
Your vehicle’s URPA operates when the shift lever
is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). Four ultrasonic
sensors located at the rear bumper are used to
detect the distance to the object. The URPA
display is located inside the vehicle, near the rear
window. It has three color-coded lights used to
provide distance and system information to
the driver.
188

{CAUTION:
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
Operate above speeds of
3 mph (5 km/h).
Detect objects more than 5 feet
(1.5 meters) behind the vehicle.
This distance may be less during
warmer or humid weather.
Detect objects that are below the
bumper, underneath the vehicle, or
that are very close to the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the URPA system,
always check carefully before backing up
by checking behind your vehicle.URPA can be turned off
by pressing the rear
park aid disable switch
located in the
overhead console
switchbank.
While the system is disabled, an indicator light
will be lit on the switch. You will not see any
lights on the rear display if the switch is in the
off position.
189

How the System Works
Unless disabled, the URPA will turn on
automatically when the shift lever is moved into
REVERSE (R). When the system turns on, the
three lights on the display will illuminate for one and
a half seconds to let you know that the system is
working. If your vehicle is moving in REVERSE (R)
at a speed greater than 3 mph (5 km/h), the red
light will ash to remind you that the system does
not work at speed greater than 3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed
of less than 3 mph (5 km/h), one of the following
will occur:
Description English Metric
amber light 5 ft 1.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights &
continuous chime20 in 0.5 m
amber/amber/
red lights ashing &
continuous chime1 ft 0.3 m
A chime will sound the rst time an object
is detected between 20 inches (0.5 m) and
5 feet (1.5 m) away.URPA cannot detect objects that are above liftgate
level. In order for the rear sensors to recognize
an object, it must be within detection range behind
the vehicle.
When the System Does Not Seem to
Work Properly
The light may ash red when the vehicle is in
REVERSE (R) if the ultrasonic sensors are
not kept clean. So be sure to keep your rear
bumper free of mud, dirt, snow, ice and slush.
Other conditions that may affect system
performance include things like the vibrations from
a jackhammer or the compression of air brakes
on a very large truck. If after cleaning the
rear bumper and then driving forward at least
15 mph (25 km/h), the display continues to ash
red, see your dealer.
If a trailer was attached to your vehicle, or a
bicycle or an object was on the back of, or hanging
out of your liftgate during your last drive cycle,
the light may also ash red. The light will continue
to ash whenever in REVERSE (R) until your
vehicle is driven forward at least 15 mph (25 km/h)
without any obstructions behind the vehicle.
