Lighting 6-9
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 are on, such
as: 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 LOW
START VEHICLE. If this message
displays, it is recommended that the
driver reduce the electrical loads as
much as possible and restart the
vehicle. See
Battery Voltage and
Charging Messages on page 5‑35.Battery Power 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.

8-2 Climate Controls
Temperature Control:Move the
thumbwheels up or down to
increase or decrease the
temperature on the driver side or
the passenger side of the vehicle for
the dual zone system.
9(Fan Control): 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.
Air Delivery Mode Control: Turn
clockwise or counterclockwise to
change the airflow direction inside
the vehicle. By positioning the knob
between two modes, a combination
of those modes is selected.
Select from the following modes:
H(Vent): Air is directed to the
instrument panel outlets.
)(Bi-Level): Air is divided
between the instrument panel and
floor outlets. Some air is directed
towards the windshield and side window outlets. Cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
6(Floor):
Air is directed to the
floor outlets, with some of the air
directed to the windshield, side
window, and second row floor
outlets. In this mode, the system
automatically selects outside air.
Recirculation cannot be selected
when in Floor Mode.
-(Defog): The defog mode is
used to clear the windows of fog or
moisture. Air is directed to the
windshield, floor outlets, and side
window vents. In 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.
0(Defrost): The defrost mode is
used to remove fog or frost from the
windshield more quickly. Air is
directed to the windshield and side
window vents, with some directed to the floor vents. In this mode, the
system automatically forces outside
air into the vehicle. The recirculation
mode cannot be selected while in
the defrost mode. The air
conditioning compressor runs
automatically in this setting, unless
the outside temperature is close to
freezing.
Do not drive the vehicle until all the
windows are clear.
#(Air Conditioning):
Press this
button to turn the air conditioning
system on or off. An indicator light
comes on to show that the air
conditioning is on. The air
conditioning can be selected in any
mode as long as the fan switch
is on.
On hot days, open the windows to
let hot inside air escape; then close
them. This helps to reduce the time
it takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.

Climate Controls 8-3
The air conditioning system
removes moisture from the air, so a
small amount of water might drip
under the vehicle while idling or
after turning off the engine. This is
normal.
h(Recirculation):Press this
button to turn the recirculation mode
on or off. An indicator light comes
on to show that recirculation is on.
This mode recirculates and helps to
quickly cool the air inside the
vehicle. It can be used to help
prevent outside air and odors from
entering the vehicle.
The recirculation mode cannot be
used with floor, defrost, or defogging
modes. If recirculation is selected
while in one of those modes, the
indicator flashes three times and
turns 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. The
recirculation mode can also be
turned off by turning off the engine.
REAR:
Press to turn the rear
heating and air conditioning on. See
Rear Climate Control System (Rear
Climate Control Only) on page 8‑10
or Rear Climate Control System
(Rear Climate with Rear Seat Audio)
on page 8‑11 for more information.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
1(Rear Window Defogger):
Press this button to turn the rear
window defogger on or off. The
system automatically turns off
several minutes after it has been
activated. The defogger can also be
turned off by turning off the engine.
Do not drive the vehicle until all the
windows are clear. For vehicles with heated outside
rearview mirrors, the mirrors will
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 the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal, or anything
similar to the defogger grid.

8-6 Climate Controls
Do not cover the solar sensor
located on the top of the instrument
panel near the windshield. This
sensor regulates air temperature
based on sun load and also turns
on the headlamps. For more
information on the solar sensor, see
“Sensors”later in this section.
To avoid blowing cold air in cold
weather, the system will delay
turning on the fan until warm air is
available. The length of delay
depends on the engine coolant
temperature. Pressing the fan
switch will override this delay and
change the fan to a selected speed.

Climate Controls 8-7
The passenger temperature control
cannot be activated while in defrost
mode. If the PASS button is
pressed, the button indicator flashes
three times and will not work. If the
passenger temperature buttons are
adjusted, the driver temperature
indicator changes. The passenger

windows are clear.
#(Air Conditioning):Press to
turn the air conditioning (A/C)
compressor on and off. An indicator
light comes on to show that the air
conditioning is on. If this button is pressed when the air
conditioning compressor is
unavailable, the indicator flashes
three times and then turns off. If the
air conditioning is on and the
outside temperature drops below a
temperature which is too cool for air
conditioning to be effective, the air
conditioning light turns off to show
that the air conditioning mode has
been canceled.
On hot days, open the windows long
enough to let hot inside air escape.
This helps to reduce the time it
takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.
The air conditioning system
removes moisture from the air, so a
small amount of water might drip
under the vehicle while idling or
after turning off the engine. This is
normal.
@(Recirculation):
Press to turn
the recirculation mode on or off. An
indicator light comes on to show
that the recirculation is on.
This mode recirculates and helps to
quickly cool the air inside the
vehicle. It can be used to help
prevent outside air and odors from
entering the vehicle.
The recirculation mode cannot be
used with floor, defog, or defrost
modes. If recirculation is selected
with one of those modes, the
indicator light flashes three times
and then turns off. The air
conditioning compressor also comes
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.
The recirculation mode can also be
turned off by turning off the ignition.

10-94 Vehicle Care
Notice:Cleaning the windshield
with water during the first three to
six months of ownership will
reduce tendency to fog.
Speaker Covers
Vacuum around a speaker cover
gently, so that the speaker will not
be damaged. Clean spots with just
water and mild soap.
Coated Moldings
Coated moldings should be cleaned.
.When lightly soiled, wipe with a
sponge or soft lint-free cloth
dampened with water.
.When heavily soiled, use warm
soapy water.
Fabric/Carpet/Suede
Start by vacuuming the surface
using a soft brush attachment. If a
rotating brush attachment is being
used during vacuuming, only use it
on the floor carpet. Before cleaning,
gently remove as much of the soil
as possible using one of the
following techniques:
.Gently blot liquids with a paper
towel. Continue blotting until no
more soil can be removed.
.For solid soils, remove as much
as possible prior to vacuuming.
To clean:
1. Saturate a clean lint-free colorfast cloth with water or club
soda. Microfiber cloth is
recommended to prevent lint
transfer to the fabric or carpet.
2. Remove excess moisture by gently wringing until water does
not drip from the cleaning cloth. 3. Start on the outside edge of the
soil and gently rub toward the
center. Fold the cleaning cloth to
a clean area frequently to
prevent forcing the soil in to the
fabric.
4. Continue gently rubbing the soiled area until there is no
longer any color transfer from
the soil to the cleaning cloth.
5. If the soil is not completely removed, use a mild soap
solution followed only by club
soda or plain water.
If the soil is not completely
removed, it may be necessary to
use a commercial upholstery
cleaner or spot lifter. Test a small
hidden area for colorfastness before
using a commercial upholstery
cleaner or spot lifter. If ring
formation occurs, clean the entire
fabric or carpet.
Following the cleaning process, a
paper towel can be used to blot
excess moisture.
