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 willflash 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:

amber/amber lights 40 in. 1.0 m
amber/amber/red lights &
continuous chime20 in. 0.5 m
amber/amber/red lights
flashing & continuous
chime1 ft 0.3 m
A chime will sound thefirst 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 mayflash 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

)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, then directs the remaining
air to thefloor outlets. Cooler air is directed to the upper
outlets and warmer air to thefloor outlets.
6(Floor):This mode directs most of the air to the
floor outlets. Use this mode to send air to the rear of the
vehicle. Keep the area under the front seats free of
objects that could obstruct airflow to the rear of
the vehicle.
The right knob can also be used to select defog or
defrost mode. For more information, see“Defogging and
Defrosting”later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the knob to 0 to turn off the fan. The fan must
be turned on for the air conditioning compressor
to operate.
@(Recirculation):This mode keeps outside air
from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or help
heat or cool the air inside your vehicle more quickly.
Press this button to turn the recirculation mode on or off.
When the button is pressed, an indicator light will
come on. The air-conditioning compressor also comes
on. The recirculation mode can be used with vent
and bi-level modes, but it cannot be used withfloor,
defog, defrost or outside air modes.Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the air
temperature inside your vehicle.
#A/C (Air Conditioning):Press this button to turn
the air-conditioning system on or off. When A/C is
pressed, an indicator light in the button will come on to
let you know that air conditioning is activated.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
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.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the coolest temperature.
3. Select the highest fan speed.
4. Select A/C.
5. Select the recirculation mode.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air
inside of your vehicle has cooled, turn the recirculation
mode off.

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
(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 thefloor 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 thefloor outlets. In this mode,
the system will automatically turn off recirculation
and run the air-conditioning compressor, unless theoutside temperature is at or below freezing.
Recirculation cannot be selected while in the
defrost mode.

will come on to let you know that the rear window
defogger is activated.
The rear window defogger will turn off approximately
10 minutes after the button is pressed. If turned on
again, the defogger will only run for approximatelyfive
minutes before turning off. The defogger can also
be turned off by pressing the button again or by turning
off the engine.
Notice:Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’tbe
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar
to the defogger grid.

2. Adjust the temperature to a comfortable setting.
Choosing the coldest or warmest temperature will
not cause the system to heat or cool any faster.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. Then, as the air warms,
it will be delivered through the instrument panel
outlets. The length of time needed for warm up will
depend on the outside temperature and the
length of time that has elapsed since your vehicle
was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature as
necessary.
