The display is located
near the passenger side
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 that will
be heard through the speakers.
URPA can be turned off
by pressing the rear
park aid disable button
located next to the
radio. The indicator will
illuminate to indicate
that URPA is off.The red light in the URPA display will also be lit if
the vehicle is in REVERSE (R). If the vehicle
has a DIC, PARKING ASSIST OFF will display.
URPA automatically turns back on each time
the vehicle is started.
How the System Works
When the shift lever is moved into REVERSE (R),
the rear display will briey come on 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 Operation and
Displays (With DIC Buttons) on page 244or
DIC Operation and Displays (Without DIC Buttons)
on page 251.
206

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 (0 km/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 come on.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be on.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/
amber/red) will be on.
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 on and
ashing.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARKING
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
Operation and Displays (With DIC Buttons)
on page 244orDIC Operation and Displays
(Without DIC Buttons) on page 251.
The parking brake pedal is depressed.
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.

If you experience a problem, see your dealer for
additional information on the accessory
power plugs.
The accessory power outlets are powered, even
with the ignition off. Continuing to use power
outlets while the ignition is off may cause
the vehicle’s battery to run down.
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. Do not use equipment
exceeding the maximum amperage rating of
20 amperes.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or

9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan
speed. Turn the knob all the way counterclockwise
to turn the front system off.
?(Recirculation):Press this button to turn
the recirculation mode on. When the button
is pressed, an indicator light will come on.
This mode keeps outside air from entering the
vehicle. It can be used to reduce outside air and
prevent odors from entering your vehicle.
Recirculation may also help cool the air inside
your vehicle more quickly once the temperature
inside the vehicle is less than the outside
temperature.
The recirculation mode cannot be used with oor,
defrost, or defogging modes. If you try to select
recirculation in one of those modes, the indicator
will ash three times and turn off. The air
conditioning compressor will also come on when
this mode is activated. While in recirculation mode
the windows may fog when the weather is cold
and damp. To clear the fog, select either the defog
or defrost mode and increase the fan speed.
Recirculation mode can be turned off by pressing
the button again, or turning off the engine.AUX (Auxiliary):Pressing this button will turn the
rear heating and air conditioning on. SeeRear
Air Conditioning and Heating System on page 220
orRear Air Conditioning and Heating System
and Electronic Climate Controls on page 222for
more information.
Temperature Control:Rotate the thumbwheels
up or down to increase or decrease the
temperature on the driver’s side or the passenger
side of the vehicle for the dual zone system.
#(Air Conditioning):Press this button on the
left knob to turn the air conditioning system on
or off. When A/C is pressed, an indicator light will
come on to let you know that the air conditioning

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.

Automatic Operation
AUTO (Automatic):When automatic operation
is active the system will control the inside
temperature, the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will
change to show the current temperature(s)
and AUTO will be lit on the display. The current
delivery mode and fan speed will also be
displayed for approximately 5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over
about 40°F (4°C). The air inlet will normally be
set to outside air. If it’s hot outside, the air
inlet may automatically switch to recirculate
inside air to help quickly cool down your
vehicle. The light on the button will illuminate
in recirculation.2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a
74°F (23°C) temperature setting and allow
about 20 minutes for the system to regulate.
Use the driver’s or passenger’s temperature
buttons to adjust the temperature setting as
necessary. If you choose the temperature
setting of 60°F (15°C), the system will remain at
the maximum cooling setting. If you choose the
temperature setting of 90°F (32°C), the system
will remain at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield.
This sensor regulates air temperature based
on sun load and also turns on your headlamps.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air
is available. The length of delay depends on
the engine coolant temperature. Pressing the fan
switch will override this delay and change the
fan to a selected speed.
