Ultrasonic Rear Parking Assist
(URPA)
The Ultrasonic Rear Parking Assist (URPA) system 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.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
parking. And, the system does not detect
objects that are more than 5 feet (1.5 meters)
behind the vehicle.
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using rear park assist,
always check carefully behind your vehicle
before you back up and then watch closely
as you do.

URPA can be turned off by
pressing the rear park aid
disable switch located
in the instrument panel
switchbank. When
the system is disabled,
an indicator light will glow
on the switch. You will
not see any lights on the
rear display if the switch
is in the off position.
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/amber lights 40 in 1.0 m
amber/amber/
red lights &

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.
3-25

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.
For cleaning instructions, seeWashing Your Vehicle
on page 5-94.
Accessory Power Outlet(s)
With accessory power outlets you can plug in electrical
equipment such as a cellular telephone or CB radio.
There is one front power outlet/cigarette lighter located
on the oor console in the cell phone storage
compartment.
There are also two rear power outlets. One is located
in the rear of the oor console below the vents. The
other is located in the rear of the vehicle on the driver’s
side behind the access door.
Pull the cover down to use an accessory power outlet.
When not in use, always cover the accessory power
outlets 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.
3-26

Certain electrical accessories may not be compatible
with the accessory power outlet 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. 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.Ashtray(s) and Cigarette Lighter
The ashtray is located on the oor console closest to
the instrument panel. Lift the lid to expose the ashtray.
To remove the ashtray, lift it up.
The cigarette lighter is located on the oor console in
the cell phone storage compartment closest to the
driver’s seat. Lift the lid to expose the cigarette lighter.
To use the lighter, push it in all the way and let go.
When it is ready, it will pop back out by itself.
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.
Notice:If you put papers, pins, or other ammable
items in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage your vehicle. Never put ammable items

still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity,
or moisture, condensing on the cool window glass.
This can be minimized if the climate controls system is
used properly. There are two modes to clear fog or
frost from your windshield. Use the defog mode to
clear the windows of fog or moisture and warm
the passengers. Use the defrost mode to remove fog
or frost from the windshield more quickly.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs air to the windshield
and the oor outlets. 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 defog mode.
0(Defrost):Pressing this button directs most of the
air to the windshield and the side window outlets, with
some air directed to the oor outlets. In this mode, the
system will automatically turn off recirculation and run
