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 244.Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until
one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off,
then on again.
The headlamps will timeout after 10 minutes,
if they are manually turned on before the
ignition is off.
189

If this occurs, URPA assumes the object is still
attached, so you will have to wait until the
vehicle is driven forward above 15 mph
(25 km/h) before URPA will return to normal
operation.
The ultrasonic sensors need to be 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 482. If the DIC still displays the
PARK ASSIST OFF message after cleaning the
bumper and driving forward at a speed of at
least 15 mph (25 km/h), see your dealer/retailer.
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.
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.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the vehicle
to your dealer/retailer to repair the system.
Accessory Power Outlet(s)
The accessory power outlets can be used to
connect electrical equipment such as a cellular
phone or CB radio.
Your vehicle may have four accessory power
outlets. They are located on the instrument panel
below the climate controls, inside the front
center console storage bin, at the rear of the
center console, and in the rear cargo area.
To use the outlets, remove the cover. When not in
use, always cover the outlet with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always
turn off electrical equipment when not in
use and do not plug in equipment that exceeds
the maximum amperage rating of 20 amperes.
197

The indicator on the inner outlet face will come on
when 115 volt AC power is available. The AC
power is available when the ignition is turned to
ACCESSORY or ON, and electrical equipment
is plugged into the outlet. The AC power is
not available in the outlet when the ignition is
turned to OFF.
The power outlet is not designed for the following
electrical equipment and may not work properly
if these items are plugged into the power outlet:
Equipment with high initial peak wattage
such as: compressor-driven refrigerators
and electric power tools.
Other equipment requiring an extremely
stable power supply such as:
microcomputer-controlled electric blankets,
touch sensor lamps, etc.
SeeHigh Voltage Devices and Wiring on
page 489.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling, defrost, defog, and ventilation of
the vehicle.
Manual Operation
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.
199

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 the
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 less
than 40°F (4°C). 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 most 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 less than 40°F (4°C).
Do not drive the vehicle until all the windows
are clear.
AUX (Auxiliary):Press this button to turn the
rear heating and air conditioning on. SeeRear Air
Conditioning and Heating System on page 211
orRear Air Conditioning and Heating System and
Electronic Climate Controls on page 212.
202

Rear Window Defogger
The rear window defogger uses a warming grid
to remove fog from the rear window.
<(Rear Window Defogger):Press this button
on the right knob to turn the rear window
defogger on or off. The rear window defogger
stays on about 10 minutes after the button
is pressed, before turning off. The defogger can
also be turned off by pressing the button again
or by turning off the engine. Do not drive the
vehicle until all the windows are clear.
If your vehicle has heated outside rearview
mirrors, the mirrors heat to help clear fog or frost
from the surface of the mirror when the rear
window defog button is pressed.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license,
tape, a decal or anything similar to the
defogger grid.
Dual Automatic Climate
Control System
With this system, you can control the heating,
cooling, and ventilation in your vehicle. Your
vehicle also has a ow-through ventilation system
described later in this section.
You can select different climate control
temperature settings for the driver and passengers.
