164 LIGHTING
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, 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. If a
battery message is displayed, it isrecommended that the driver reduce
the electrical loads as much as
possible. See
Driver Information Center
(DIC) 0132.
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 off
position and then back to the parking
lamp or headlamp position. To keep the lamps on for more than
10 minutes, the ignition must be in
the ACC/ACCESSORY or ON/RUN/
START position.

Climate Control Status Screen
The climate control status screen
appears briefly when the climate
control buttons on the faceplate are adjusted. The air delivery mode can be
adjusted on the climate control status
screen.
Climate Control Function with Stop/
Start (If Equipped)
The climate control system depends
on other vehicle systems for heat and
power input. The climate control
system will balance stop/start
efficiency with air conditioning
comfort and defog operation. Certain
climate control settings can result in
fewer Auto Stops.
The following are climate control
settings that result in fewer Auto
Stops:
.
The defrost mode.
. High fan speed settings.
. Extreme temperature settings.
For maximum air conditioning
comfort, use the stop/start disable
switch. See “Auto Engine Stop/Start ”
under Starting the Engine 0198.

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 the indicator light is on or
AUTO is displayed on the touch
screen, the system is in full automatic
operation. If the air delivery mode or

as needed.
Automatic Air Recirculation :
When
the AUTO indicator light is on, the air
is automatically recirculated as
needed to help quickly cool the inside
of the vehicle.
The climate control system may have
a sensor to detect air pollution. When
using automatic air recirculation, the
air quality control system may
operate. To adjust the sensitivity of
the air quality sensor, see “Climate
and Air Quality” underVehicle
Personalization 0149.@:Press to alternate between
recirculating air inside the vehicle or
pulling in outside air. The indicator
light on the button is lit when
recirculation mode is active. This
helps to quickly cool the air inside the
vehicle or reduce the outside air and
odors that might enter. Pressing this button cancels automatic
recirculation. Press AUTO to return to
automatic operation; recirculation
runs automatically as needed.
Manual recirculation mode is not
available when in Defrost or Defog
modes.
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. 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 0149.Rear Window Defogger
=:Press to turn the rear window
defogger on or off. An indicator light

(40 °F) and below.
The upper gridlines on the rear
window are antenna lines and are not
intended to heat when the defogger is
activated.
The heated outside rearview mirrors
turn on when the rear window
defogger button is on and help to
clear fog or frost from the surface of
the mirrors.
Caution

The climate control system uses the
sensor information to adjust the
temperature, fan speed, recirculation,
and air delivery mode for best
comfort.
If the sensor is covered, the automatic
climate control system may not work
properly.
Air Quality Sensor
If equipped with an air quality sensor,
the climate control system adjusts to
limit some exhaust fumes from being
pulled inside the vehicle.
Press the AUTO button on the climate
control to activate the air quality
sensor. Recirculation is automatically

extended period to prevent the air
inside the vehicle from becoming too
dry or stuffy.
Under certain conditions, the air
quality sensor will not activate, such
as during cold weather or with
extreme odors. Press
@to activate
recirculation. The air quality sensor system does not
protect against carbon monoxide (CO),
