When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC),
you may see the voltage move up or down.
This is normal. If there is a problem, an alert will
be displayed.
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 267.
Battery Run-Down Protection
This feature shuts off the dome lamps if they
are left on for more than 10 minutes when
the ignition is in LOCK. This will help prevent
the battery from running down.
221

The air conditioning compressor will be on unless
the outside temperature is close to freezing.
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.
:(Outside Air):Press this button to turn
on the outside air mode. When this mode
is selected, air from outside the vehicle will
circulate throughout your vehicle. An indicator
light on the button will come on to let you know
that it is activated. The outside air mode can
be used with all modes, but it cannot be used
with the recirculation mode. Pressing this button
again will cancel the recirculation mode.
?(Recirculation):Press this button to turn
on the recirculation mode. 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
light 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.
Temperature Control:Rotate the thumbwheels
up or down to increase or decrease the
temperature on the driver’s side or the passenger
side to the vehicle for the dual zone system.
228

#(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.
-(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.
229

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 on the rear window
defogger. The system will automatically turn off
several minutes after it has been activated.
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 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
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 settings
for the driver and passengers.
230

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.
O(On/Off):Press this button to turn off the
climate control system. Outside air will still enter
the vehicle, and will be directed to the oor.
This direction can be changed by pressing the
mode button. Recirculation can be selected once
you have selected vent or bi-level mode. The
temperature can also be adjusted using either
temperature button. If you adjust the air delivery
mode or temperature settings with the system
off, the display will illuminate briey to show
you the settings and then return off. Press the
on/off button or the up down arrows on the
fan switch, the defrost button, AUTO button,
or the air conditioning button to turn the system
on when it is off.
Manual Operation
You may manually adjust the air delivery mode
or fan speed.
y9z(Fan):The buttons with the fan symbols
allow you to manually adjust the fan speed.
Press the up arrow to increase fan speed and
the down arrow to decrease fan speed.
Pressing one of these buttons when the system
is off will turn the system on. Pressing one of these
buttons when in automatic control will place the
fan under manual control. The fan setting will
remain displayed and the AUTO light will turn off.
The air delivery mode will remain under
automatic control.
yNz(Mode):Press the mode up and down
buttons to manually change the direction of
the airow in your vehicle. Repeatedly press the
button until the desired mode appears on the
display. Pressing one of these buttons when the
system is off will change air delivery mode without
turning the system on. Pressing one of these
buttons when in automatic control will place the
mode under manual control.
233

The air delivery mode setting will be displayed
and the AUTO light will turn off. The fan will
remain under automatic control.
H(Vent):This setting will deliver 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.
-(Defog):See “Defogging and Defrosting” later
in this section.
@(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.
234

;(Outside Air):Press this button to turn
on the outside air mode. When this mode is
selected, air from outside the vehicle will circulate
throughout your vehicle. An indicator light on
the button will come on to let you know that it
is activated. The outside air mode can be
used with all modes, but it cannot be used with
the recirculation mode. Pressing this button
again will cancel the recirculation mode.
Air Conditioning
#
(Air Conditioning):Press this button to
turn the air conditioning (A/C) compressor on
and off. When air conditioning is selected,
an indicator light will come on to let you know
that the air conditioning has been activated.
Pressing this button when the outside
temperature is too cool for air conditioning
will make the air conditioning indicator ash
three times and then turn off to let you know
the air conditioning mode is not available.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 will turn off to let
you know 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 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.
