Outside Convex Mirror
Your passenger’s side mirror may have convex
glass. A convex mirror’s surface is curved so you
can see more from the driver’s seat.
{CAUTION:
A convex mirror can make things (like
other vehicles) look farther away than they
really are. If you cut too sharply into the
right lane, you could hit a vehicle on your
right. Check your inside mirror or glance
over your shoulder before changing lanes.
Outside Heated Mirrors
The vehicle may have outside heated mirrors which
help clear them of condensation, snow, and ice.
When the rear window defogger button is pressed,
the heated mirrors are also turned on. See “Rear
Window Defogger” underDual Automatic Climate
Control System on page 231orClimate Control
System on page 227for more information.

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 ash. 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.Rear Window Wiper/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.
The rear wiper control is located on the turn
signal/multifunction lever.
To turn the rear wiper on, slide the lever to a
wiper position.
9(Off):To turn the wiper off, slide the lever to
this setting.
5(Rear Wiper Delay):To turn on the rear wiper
delay, slide the lever to this setting.
Z(Rear Wiper):To turn on the rear wiper, slide
the lever to this setting.

The battery can be discharged at idle if the
electrical loads are very high. This is true for
all vehicles. This is because the generator
(alternator) may not be spinning fast enough at
idle to produce all the power that is needed for very
high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 270.
Battery Run-Down Protection
This feature shuts off the dome, and reading
lamps if they are left on for more than 10 minutes
when the ignition is off. This will keep the
battery from running down.
221

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 557. 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 by pressing the rear park aid
button, the indicator light will ash for
3 seconds and then stay lit to indicate that
URPA is off.
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 270.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
Accessory power outlets can be used to
connect auxiliary electrical equipment, such as a
cellular telephone or CB radio. The outlet can
accept electrical equipment up to a maximum of
20 amperes.
There are four accessory power outlets. There are
two 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.
225

Ashtray(s) and Cigarette Lighter
The front ashtray is located near the center of the
instrument panel or on the front console, if
equipped. Pull on the ashtray door to open it.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle. Never
put ammable items in the ashtray.
To remove the front ashtray pull the ashtray up.
To use the cigarette lighter, push it in all the way,
and let go. When it’s ready, it will pop back out
by itself.
Notice:Holding a cigarette lighter in while it
is heating does not let the lighter back
away from the heating element when it is hot.
Damage from overheating can occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in while it
is heating.
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.
227

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 239
orRear Air Conditioning and Heating System
and Electronic Climate Controls on page 240for
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.
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.
