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 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 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.

Cleaning the Outside
of Your Vehicle on page 5-95.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
Turn the right knob clockwise or counterclockwise to
direct the air¯ow inside of your vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, then directs the remaining
air to the ¯oor outlets. Cooler air is directed to the upper
outlets and warmer air to the ¯oor outlets.
6(Floor):This mode directs most of the air to the
¯oor 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 air¯ow to the rear of
the vehicle.
The right knob can also be used to select defog or
defrost mode. For more information, see ªDefogging and
Defrostingº later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the knob to OFF to turn off the fan. The fan
must be turned on for the air conditioning compressor to
operate.
:(Outside Air):Press this button to turn the
outside air mode on or off. When this mode is on,
outside air will circulate throughout your vehicle. When
this mode is on, an indicator light in the button will
come on to let you know that it is activated. The outside
air mode can be used with all modes, but it cannot
be used with the recirculation mode.
3-28

?(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 with ¯oor,
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 recirculation mode.
3. Select A/C.
4. Select the coolest temperature.
5. Select the highest fan speed.
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,
or 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 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.
