A chime will sound the first time an object is detected.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the rear
sensors to recognize an object, it must be within
operating range.
If the URPA system is not functioning properly, the
display will flash red, indicating that there is a problem.
The light will also flash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on
the back of, or hanging out of your trunk. The light
will continue to flash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h). It may also flash red if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush or the system may not
work properly. If after cleaning the rear bumper and
driving forward at least 15 mph (25 km/h), the display
continues to flash red, see your dealer. It may also flash
red if your vehicle is moving in REVERSE (R) at a
speed greater than 3 mph (5 km/h). 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.
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.
For cleaning instructions, see ªCleaning Your Vehicleº
in the Index.

Comfort Controls
This section tells you how to make your air system work
for you.
Climate Control Panel
Your vehicle is equipped with a dual-zone electronic
climate control system. This system can automatically
adjust and control temperature, fan speed, air delivery
mode, air conditioning operation and air intake. You can
use the AUTO (automatic) setting or override the
automatic operation by manually altering the controls.
If your vehicle is equipped with the Climate Control
Personalization feature, you will be able to programyour preferred climate control settings by using your
remote keyless entry transmitter. See ªclimate control
personalizationº in the Index.
AUTO: The AUTO button will turn on the system
and automatically adjust the fan blower speed, air
delivery mode and temperature to your previously
programmed settings.
TEMP: This knob adjusts the air temperature coming
through the system. Turn the TEMP knob clockwise to
increase the temperature and counterclockwise to
decrease the temperature. You may also press the TEMP
knob to turn the system on and off. (You can turn the
comfort control system on by pressing any button on the
panel. The passenger's TEMP knob only turns off the
system of the passenger's side.) Once the system is
turned off, fresh air will continue to flow through the
vehicle, and the system will try to maintain the
previously set temperature.
Driver's Side Temperature Knob
You can control the temperature of the driver's side
independently from the passenger's side. Turn the
driver's side TEMP knob clockwise to increase the
temperature and counterclockwise to decrease
the temperature.

3-3
Passenger's Side Temperature Knob
The right front passenger can control the temperature of
air for both the front passenger and rear seat area. (The
passenger's and driver's knob adjust from 60
F (16
C)
to 90
F (32
C) independent of each other. It is
suggested, however, that the passenger's setting stay no
more than four degrees warmer or cooler in temperature
from the driver's setting.) To turn the system on, press
the passenger's side TEMP knob. Turn the passenger's
side TEMP knob clockwise to increase the temperature
and counterclockwise to decrease the temperature. Press
the passenger's side TEMP knob again to turn off the
passenger's side system. If the passenger's side is turned
off, the driver's side will control the temperature of the
entire vehicle.
Automatic Operation
When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor, the instrument panel or windshield outlets.
The fan speed will vary as the system maintains the
selected temperature setting.
Be careful not to put anything over the electronic solar
sensors located near the ends of the instrument panel
near the windshield. These sensors are used by the
automatic system to regulate temperature.To find your comfort zone, start with the 75
F (24
C)
setting and allow about 30 minutes for the system to
regulate. Turn the TEMP knob to adjust the temperature
if necessary. If you choose 60
F (16
C), the system
will remain at that maximum cooling setting and will
not regulate fan speed. If you choose 90
F (32
C),
the system will remain at that maximum heating setting
and will not regulate fan speed. Choosing either
maximum setting will not cause the system to heat or
cool any faster.
With the automatic setting, the air conditioning
compressor cycles when needed to cool the air. In cold
weather, when the system senses the need for heat, the
airflow will be directed out the floor outlets. As the
interior temperature approaches a desired setting, the
blower speed will decrease. To maintain interior
comfort, the airflow may move to the instrument panel
air outlets and floor outlets (bi
-level mode). On bright
sunny days in cold weather, the airflow may come out of
the air conditioning outlets (A/C mode) to maintain
comfort and prevent stuffiness.
If your vehicle is sitting out on a hot day and you have it
set on AUTO, the air will first flow out the floor outlets
for a few seconds. This is normal. This is to remove hot
air from the air outlets. As the air is cooled, the airflow
will move through the air conditioning outlets.

3-4
To avoid blowing cold air in cold weather, the system
will start at reduced fan speeds until warm air is
available. The length of reduction depends on the
outside air temperature, engine coolant temperature or
the time since the engine was last started. As the coolant
warms up, the blower fan speed will gradually increase
and air will flow from the heater outlets, with some
airflow to the windshield to prevent fogging under most
normal conditions. If you select defrost mode or a
manual fan speed, this function will be skipped.
If you leave your vehicle, the system will remember the
control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation. Defrost will change to automatic
operation when the ignition is shut off and then turned
back on.Manual Operation
You may manually adjust the air delivery mode, fan
speed, air input and compressor operation using the
following controls.
DEFROST (FRONT): Press this button to quickly
remove fog or frost from the windshield. This setting
sends most of the airflow to the windshield with only a
small amount to the floor outlets.
RECIRCULATION: Press this button to limit
the amount of fresh air entering your vehicle. This is
helpful when you are trying to cool the air quickly or
limit odors entering your vehicle. In the AUTO mode,
the system will use recirculation as necessary to cool the
air. Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non
-stop. Press this button again to turn off the
recirculation feature. If you notice the windows fogging,
press the recirculation button to exit the recirculation
mode. Recirculation is not available in the defrost mode.

3-5
A/C: Press this button to turn the air conditioning
compressor on and off. When you press the button, an
A/C OFF message appears on the climate control panel's
display. Press the button again and the air conditioner
will return to automatic control. The system will cool
and dehumidify the air inside the vehicle. In the
automatic mode, the air conditioning compressor only
operates when the system determines it is needed. The
A/C OFF function is not available in the defrost mode.
MODE: Press this button (the right or left arrow) to
deliver air through the floor, instrument panel or
windshield outlets. The climate control system will stay
in the selected mode until the MODE button, the
DEFROST button or the AUTO button is pressed again.
Press the left or right arrow to cycle through the
following available modes.
UPPER: This setting directs airflow through the
middle instrument panel outlets. Your vehicle is
equipped with a driver's side lap cooler which will also
come on when the upper vents are being used.
BI-LEVEL: This setting directs air into your
vehicle in two ways. Cool air is directed to the upper
portion of your body through the four instrument panel
outlets while warmed air is directed to the floor.
DEFOG: This setting directs air to the floor
outlets and toward the windshield.
HEATER: This setting directs warmed air
through the floor outlets. Some warm air is diverted to
the windshield to minimize fogging.
FAN: The button with the fan symbol adjusts the
fan speed. Press the up arrow to increase fan speed and
the down arrow to decrease fan speed. Press the AUTO
button to set the fan speed for automatic operation. If it
is cold outside, the blower may not run in the maximum
high fan speed right away. The system checks the
temperature of the engine coolant to assure it is warm
enough to provide heat. When the engine coolant is
warm, the controller allows the fan to gradually increase
to a higher speed. This prevents cold air from blowing
into the passenger's compartment. Selecting a manual
fan speed will override this feature.
