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, the Driver
Information Center (DIC) message might display
Battery Saver Active. If this message is displayed,
it is recommended that the driver reduce the
electrical loads as much as possible. See
DIC Warnings and Messages on page 208.Battery Run-Down Protection
This helps prevent the vehicle’s battery from
draining in case the interior courtesy lamps,
reading lamps, trunk lamp, underhood lamp, glove
box lamps, or sun visor vanity lamps, if equipped,
are accidently left on. If any of these lamps
are left on while the ignition is off, they will
automatically turn off after 10 minutes. The lamps
will not come back on again until one of the
following occurs:
The ignition is turned on.
The interior lamps control is turned off, then to
door or on.
Ultrasonic Rear Parking
Assist (URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help
you park while in REVERSE (R) and operates only
at speeds less than 3 mph (5 km/h). URPA can help
you avoid colliding with objects such as parked
vehicles. The system can detect objects 5 feet
(1.5 m) behind your vehicle and tell you how close
those objects are to your rear bumper.
164

Accessory Power Outlet(s)
The accessory power outlets enable power
electrical equipment such as a cellular telephone
or a CB radio to be used inside the vehicle.
Your vehicle has 12-volt outlets. One outlet is
located on the center console below the climate
controls. There may be another outlet located
inside the center storage console or in the ip and
fold console.
Open the cover to use the outlet. Be sure to close
the cover when the outlet is not in use.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your warranty.
Do not use equipment exceeding maximum
amperage rating of 20 amperes. Check with
your dealer before adding electrical equipment.Certain power accessory plugs may not be
compatible to the power accessory outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
167

Ashtray(s) and Cigarette Lighter
Your vehicle may have a removable ashtray and
cigarette lighter. The cigarette lighter may be
located under the climate control system.
The removable ashtray can be placed into the
front console cupholder.
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 use the cigarette lighter, push it in all the way,
and let go. When the heating element is ready,
it will pop back out by itself.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away
from the heating element when it is hot. Damage
from overheating may occur to the lighter or
heating element, or a fuse could be blown. Do
not hold a cigarette lighter in while it is heating.
Do not use equipment exceeding maximum
amperage rating of 20 amperes.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling and ventilation for your vehicle.
If your vehicle has the remote start feature and
it is activated, the climate control system will
automatically cool the vehicle if the temperature is
greater than 90°F (32°C) and heat the vehicle if the
temperature is below 37°F (3°C). If the temperature
is between 37°F (3°C) and 90°F (32°C), the last
control setting selected when the engine was
running will be used. Normal operation and the last
setting of the climate control system will return after
the key is turned to the RUN position.
168

Operation
OFF:Turn the left knob to this position to turn the
climate control system off.
9(Fan):Turn the knob by this symbol, located
on the left side of the climate control panel,
clockwise or counterclockwise to increase or
decrease the fan speed. The fan speed will be
temporarily reduced between the transition
to a new mode. The fan will resume the original
speed when the transition to the new mode
is complete.
Temperature Control:Turn the center knob
clockwise or counterclockwise to increase
or decrease the temperature inside your vehicle.Use the right knob to select from the
following modes:
H(Vent):This mode directs outside air to the
instrument panel outlets. If driving in city
traffic, and the vehicle is stopped and idling, or the
weather is hot, turning on the recirculation
mode helps to prevent the air inside the vehicle
from becoming stale. After ve minutes recirculate
will allow some outside air into the vehicle.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets, and the remaining
air to the oor outlets. Some air may be directed
toward the windshield. Slightly cooler air is directed
to the instrument panel outlets and warmer air is
directed to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed toward
the side window outlets and a little air directed to
the windshield.
In this mode, the system will automatically use
outside air. The air conditioning compressor will be
engaged unless the outside temperature is 40°F
(4°C) or below.
169

Defogging and Defrosting
Fog on the inside of the vehicle is a result of high
humidity causing moisture to condense on the
cool window glass. This can be minimized if the
climate control system is used properly. There are
two modes to clear frost or fog from the windshield.
Use the defog mode to clear the windows of
condensation and to warm the vehicle’s occupants.
Use the defrost mode to remove frost or
condensation from the windshield quickly.
See “Rear Window Defogger” later in this section
for information on clearing the rear window of
fog or ice.
Turn the right knob to select the defog or
defrost mode.
Do not drive the vehicle until all windows
are clear.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets and half to
the oor outlets. When you select this mode, the
system turns recirculation off and runs the air
conditioning compressor unless the outside
temperature is near or below freezing. Pressing the
recirculation button will have no effect other than
turning on the indicator light while in defog mode.
0(Defrost):This mode directs most of the air to
the windshield and the side window outlets, with
some air directed to the oor outlets. When
you select this mode, the system turns
recirculation off and runs the air conditioning
compressor unless the outside temperature is near
or below freezing. Pressing the recirculation
button will have no effect other than turning on the
indicator light while in defrost mode.
171

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press the button to turn the rear
window defogger on or off. An indicator light below
the button will come on to let you know that the
rear window defogger is activated.
The rear window defogger will only work when the
ignition is in RUN. The rear window defogger
will stay on for about 20 minutes after the button is
pressed. If turned on again, the defogger will
only run for about 20 minutes 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 windows are clear.
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 for the vehicle.
172

Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode, and the fan speed. There might
be a delay of two to three minutes before the fan
comes on when the automatic operation is
used in cold weather. For the automatic system to
function, the temperature must be set between
61°F (15°C) and 89°F (32°C).
1. Adjust the temperature to a comfortable
setting.
2. Press the PASS button or the up or down
arrows on the passenger side to turn the
passenger temperature set on and off. When
turned on, the passenger temperature will
be the same as the driver setting. Press the
up or down arrow on passenger side to adjust
the passenger temperature setting.
When the passenger’s temperature set is off,
the passenger display will be off and the
driver’s set temperature will be for the driver
and passenger.In cold weather, the system will start at
reduced fan speeds to avoid blowing cold air
into the 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 the 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.
Do not cover the solar sensor located in the
center of the instrument panel, near the
windshield. For more information on the solar
sensor, see “Sensors” later in this section.
4. Press OFF to turn the climate control system
off. Only the rear defog and heated seats will
function. Press AUTO or any other button
except the heated seats or rear defog to turn
the climate control system back on.
