Windshield Washer
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.
L(Washer Fluid):There is a paddle marked
with the windshield washer symbol at the top of the
multifunction lever. To spray washer uid on the
windshield, push the paddle. The wipers will clear
the window and then either stop or return to your
preset speed.
Heated Windshield Washer
If your vehicle has the heated windshield washer
uid system it may be used to help clear ice,
snow, tree sap, or bugs from your windshield.The button is located in
the switchbank under
the climate controls.
Push the heated washer uid button to activate
the heated windshield washer uid system.
The indicator light will be on. This activation will
initiate four heated wash/wipe cycles. The rst
heated wash/wipe cycle may take up to 40 seconds
to occur, depending on outside temperature.
After the rst wash/wipe cycle, it may take up to
20 seconds for each of the remaining cycles to
begin. Press the button again to turn off the
heated windshield washer uid system or it will
automatically turn off after four wipe cycles have
been completed.
When the heated windshield washer uid system
is activated under certain outside temperature
conditions, steam may ow out of the washer
nozzles for a short period of time before washer
uid is sprayed. This is a normal condition.

The ultrasonic sensors are not kept clean.
So, be sure to keep your vehicle’s rear bumper
free of mud, dirt, snow, ice, and slush. For
cleaning instructions, seeWashing Your
Vehicle on page 532. If the DIC still displays the
PARKING ASSIST OFF message after
cleaning the bumper and driving forward at a
speed of at least 15 mph (25 km/h), see your
dealer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
When URPA is disabled without driver action
and the driver attempts to turn URPA back on
using the Driver Information Center (DIC), the
PARKING ASSIST ON option will not be
selectable if the necessary conditions stated
above for normal system operation are not met.
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 Driver Information Center messages related to
URPA, seeDIC Warnings and Messages on
page 254.
If the bumper is damaged, your URPA system
may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
With accessory power outlets you can plug in
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
Your vehicle will have two accessory power
outlets under the climate controls, one on the back
of the oor console and a additional accessory
power outlet in the rear cargo area on the
passenger side.
To use the power outlet, lift the spring cap and
insert electrical 12V device plug. To close
the power outlet, remove 12V electrical device
plug and the spring cap will close.
Certain power accessory plugs may not be
compatible to the accessory power outlet and
could result in blown adapter or vehicle fuses.

Climate Controls
Climate Control System
With this system you can control the heating,
cooling, defrost, defog and ventilation of your
vehicle.
Manual Operation
Turn the right knob clockwise or counterclockwise
to direct the airow 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 and to the oor outlets.
The ow can be divided between vent and oor
outlets depending upon where the knob is placed
between the settings. A little air is directed towards
the windshield and side window 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, with some of the air directed
to the windshield, side window outlets, and
second row oor outlets. In this mode, the system
will automatically select outside air. Recirculation
cannot be selected when in Floor Mode.
The right knob can also be used to select defog or
defrost mode. For more information, see
“Defogging and Defrosting” later in this section.
By positioning the right knob between two modes,
a combination of those two modes is selected.
The air conditioning compressor will be on unless
the outside temperature is close to freezing.
210

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
has been activated.
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.
211

Defogging and Defrosting
Fog on the inside of the 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 or frost from your
windshield. Turn the right knob clockwise to select
the defog or defrost mode.
-(Defog):The defog mode is used to clear
the windows of fog or moisture and warm
the passengers. This mode directs air to the
windshield, oor outlets, and side window vents.
When you select this mode, the system turns
off recirculation and runs the air conditioning
compressor unless the outside temperature is
close to freezing. The recirculation mode cannot
be selected while in the defog mode. Do not drive
the vehicle until all the windows are clear.
0(Defrost):The defrost mode is used to
remove fog or frost from the windshield more
quickly. This mode directs a portion of the air to
the windshield and side window vents and some to
the oor vents. In this mode, the system will
automatically force outside air into your vehicle.
The recirculation mode cannot be selected while in
the defrost mode. The air conditioning compressor
will run automatically in this setting, unless the
outside temperature is close to freezing.
Do not drive the vehicle until all the windows
are clear.
