Lighting 151When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. The voltmeter
gauge or the voltage display on the
Driver Information Center (DIC),
if equipped, may show the voltage
moving 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 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 DIC message might
be displayed and it is recommended
that the driver reduce the electrical
loads as much as possible.
Battery Power Protection The battery saver feature is
designed to protect the vehicle's
battery.
If some interior lamps are left on
and the ignition is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time. Exterior Lighting Battery
Saver The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
on. This protects against draining
the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the
O position and then back to
the
; or
2 position.
To keep the lamps on for more than
10 minutes, the ignition must be on
or in ACC/ACCESSORY.

Automatic Operation
The system automatically controls
the fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to
the desired temperature.
When AUTO is lit, all four functions
operate automatically. Each function
can also be manually set and the
selected setting is displayed.
Functions not manually set will
continue to be automatically
controlled, even if the AUTO
indicator is not lit.
For automatic operation:
1. Press AUTO. 2. Set the temperature. Allow the
system time to stabilize. Adjust
the temperature as needed for
best comfort.
To improve fuel efficiency and to
cool the vehicle faster, recirculation
may be automatically selected in
warm weather. The recirculation
light will not come on. Press
@ to
select recirculation; press it again to
select outside air.
Q /
R : The temperature can be
adjusted separately for the driver
and the passenger. Press to
increase or decrease the
temperature.
SYNC : Press to link the passenger
and rear climate temperature
settings to the driver setting. The
SYNC indicator light will turn on.
When the passenger or rear climate
settings are adjusted, the SYNC
indicator light turns off.
Manual Operation
O : Press to turn the fan off or on.
When off is selected, the system will
prevent outside air from entering the vehicle. If any climate control
buttons are pressed, the system will
turn on and operate at the current
setting.
Q ^ or
^ R : Press to increase or
decrease the fan speed. The fan
speed setting appears on the main
display. Pressing either button
cancels automatic fan control and
the fan is controlled manually. Press
AUTO to return to automatic
operation.

Climate Controls 155To change the current mode, select
one or more of the following:
X : Clears the windows of fog or
moisture. Air is directed to the
windshield.
Y : Air is directed to the instrument
panel outlets.
[ : Air is directed to the floor
outlets.
0 MAX : Air is directed to the
windshield and the fan runs at a
higher speed. Fog or frost is cleared
from the windshield more quickly.
When the button is pressed again,
the system returns to the previous
mode setting.
For best results, clear all snow and
ice from the windshield before
defrosting.
A/C : Press to turn the air
conditioning system on or off. If the
climate control system is turned off
or the outside temperature falls
below freezing, the air conditioner
will not run. Pressing this button cancels
automatic air conditioning and turns
off the air conditioner. Press AUTO
to return to automatic operation and
the air conditioner runs
automatically as needed. When the
indicator light is on, the air
conditioner runs automatically to
cool the air inside the vehicle or to
dry the air needed to defog the
windshield faster.
@ : Press to turn on recirculation.
An indicator light comes on. Air is
recirculated to quickly cool the
inside of the vehicle or to reduce the
entry of outside air and odors.
Auto Defog : The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate
control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation. To turn Auto Defog off or on, see
“ Climate and Air Quality ” under
Vehicle Personalization 0 133 .
Ionizer : If equipped with an ionizer,
this feature helps to clean the air
inside the vehicle and remove
contaminants such as pollen, odors,
and dust. If the climate control
system is on and the ionizer is
enabled, the ionizer status indicator
will be lit on the climate control
display. To turn the ionizer on or off,
see “ Climate and Air Quality ” under
Vehicle Personalization 0 133 .
Rear Window Defogger
K : Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The defogger can be turned off by
turning the ignition to off or ACC/
ACCESSORY.
The rear window defogger can be
set to automatic operation. See
“ Climate and Air Quality ” under
Vehicle Personalization 0 133 .
When auto rear defog is selected,
the rear window defogger turns on

156 Climate Controls automatically when the interior
temperature is cold and the outside
temperature is about 7 °C (44 °F)
and below. The auto rear defogger
turns off automatically.
If equipped, the heated outside
mirrors turn on when the rear
window defogger button is on and
help to clear fog or frost from the
surface of the mirror. See Heated
Mirrors 0 28 .
CautionDo not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything
else that is sharp. This may
damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.
J or
z : Press
J or
z ,
if equipped, to heat the driver or
passenger seat. Press
C or

Sensor The solar sensor, on top of the
instrument panel near the
windshield, monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise
the automatic climate control system
may not work properly.
