How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). 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 a
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 trunk 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 hanging out of your trunk 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 5-98.

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode,
the air conditioning compressor, and the fan speed.AUTO will appear on the display next to the fan, mode
indicators, and recirculation indicator if your vehicle
is equipped with the optional air quality sensor.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting,
generally, between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature setting
will not cause the system to heat or cool any faster.
If you set the system at the warmest temperature
setting, the system will try to continuously heat the
vehicle and will not adjust the system down as the
vehicle warms up.
In cold weather, the system may start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will start out
blowing air at the oor but may change modes,
automatically, as the vehicle warms up to maintain
the chosen temperature setting.
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, if
necessary. Vehicles With Heated and Ventilated Seats Shown,

You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Controls
and Displays on page 3-74.
The air-conditioning system removes moisture from the
air, so you may notice water dripping underneath
your vehicle while idling or after turning off the engine.
This is normal.
Manual Operation
yNz(Mode):Pressing the mode switch and
changing the mode cancels automatic operation and
allows the operator to manually select the air delivery
location. Press AUTO to return to automatic operation.
The outboard air outlets will always receive air ow
regardless of the mode selected. SeeOutlet
Adjustment on page 3-54to change this air ow
from the outboard outlets.
To change the current mode, select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs approximately half
of the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets.
In automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets, and a little air directed to the windshield and
side windows.
The mode switch can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.
yAz(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and allows the operator to manually
select the amount of air ow. Press AUTO to return to
automatic operation.
If the air ow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-55and
Scheduled Maintenance on page 6-4.
h(Recirculation):This button controls the air source
for the climate control system. If you are in AUTO mode,
pressing this button once will choose recirculation. This
mode keeps outside air from coming in the vehicle and
recirculates the air in the vehicle. It can be used to
prevent outside air and odors from entering your vehicle
or to help cool the air inside your vehicle more quickly.
3-49
Recirculation is not available in the defrost mode and
will shut off when defog mode is selected. Both of these
features are designed to limit fogging in your vehicle.
If recirculation is selected during defog mode, it will
automatically turn off after 10 minutes to limit problems
with fogging.
In some conditions, using recirculation for long periods
of time may cause the air inside your vehicle to become
too dry or stuffy. To prevent this from happening, after
the air in your vehicle has cooled, select AUTO to return
to automatic climate control operation or push the
recirculation button again to select outside air.
Pressing this button a second time selects outside air.
:(Outside Air):This mode forces the system to
pull air from outside the vehicle. It can be used to bring
fresh air into the vehicle.
Air Quality Sensor:Your vehicle may be equipped
with an optional air quality sensor to help limit the
climate control system from pulling in some harmful
exhaust fumes from older, poorly running or
diesel-equipped vehicles that are driving near you.This sensor, when active, will monitor the air quality in
front of your vehicle and switch to air recirculation when
poor quality air is detected outside your vehicle. You
can activate the air quality sensor on your vehicle
(if equipped) by pressing the AUTO button on your
climate control. The word AUTO will be shown in the
center of the climate control display under the outline
shape of a vehicle. When the air quality sensor senses
poor quality air, the recirculation graphic will be shown as
long as the sensor senses poor quality air.
Under some conditions, the air quality sensor system will
not operate. In cold weather, the system may not be
active (even if the AUTO indication is displayed) because
of concerns of fogging your windows, which may occur by
activating recirculation mode. Also, the air quality sensor
system will not remain in recirculation mode for extended
periods of time that could cause stuffy or very dry
conditions in the vehicle. Following a poorly running
vehicle for an extended period of time may not keep
recirculation active inde nitely.

Sensors
There is a solar sensor located on the instrument panel,
near the windshield.
There is also an interior temperature sensor located
next to the steering wheel on the instrument panel.
These sensors monitor the solar radiation and the air
inside your vehicle, then use the information to maintain
the selected temperature by initiating needed
adjustments to the temperature, the fan speed and the
air delivery system. The system may also supply
cooler air to the side of the vehicle facing the sun. The
recirculation mode may also be activated, as
necessary. Do not cover the sensors or the automatic
climate control system will not work properly.
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 control system is
used properly. There are two modes to clear fog 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.
yNz(Mode):Press this button until defog appears
on the display.
-(Defog):This mode directs the air between the
windshield and oor outlets with some air supplied to the
outboard panel outlets and side window defogging
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 is cancelled when you enter
defog mode. If you select recirculation while in defog
mode, it will be cancelled after 10 minutes.
If you have fogging on the side windows, remain in
defog or defrost mode until they clear.
3-52
Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
See “MPH (km)” underDIC Controls and Displays
on page 3-74for more information.
The odometer mileage can be checked without the
vehicle running. Your vehicle’s odometer works together
with the driver information center. You can set a Trip A
and a Trip B odometer. See “Trip Information” underDIC
Controls and Displays on page 3-74for more information.
If your vehicle ever needs a new odometer installed, the
new one will be set to the correct mileage total of the
old odometer.
Tachometer
This gage indicates the
engine speed in
revolutions per
minute (rpm).
Safety Belt Reminder Light
When the ignition button is pressed to START, a chime
will be provided for several seconds to remind people
to buckle their safety belts. The driver safety belt
light will also be provided and stay on for several
seconds, then it will ash for several more. You should
buckle your seat belt.
This chime and light will be
repeated if the driver
remains unbuckled and the
vehicle is in motion.
If the driver’s belt is buckled, neither the chime nor the
light will be provided.
