LIGHTING 161
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) 0138.
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
2position. To keep the lamps on for more than
10 minutes, the ignition must be on or
in ACC/ACCESSORY.

application.
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 climate control settings
result in fewer Auto Stops:
.
Defrost mode
. High fan speed settings
. Extreme temperature settings
For maximum air conditioning
comfort, use the Stop/Start disable
switch. See “Auto Stop/Start ”under
Starting the Engine 0195.

automatic recirculation. Touch or
press AUTO on the display or center
stack 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”

The rear window defogger turns off
automatically after about 15 minutes.
At higher vehicle speeds, the rear
window defogger may stay on
continuously.
The rear window defogger can be set
to automatic operation. See “Climate
and Air Quality” underVehicle
Personalization 0145. When Auto Rear
Defog is selected, the rear window
defogger turns on automatically when
the interior temperature is about 4 °C
(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 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
Do 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

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.
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.
Touch or press AUTO on the display
or center stack to activate the air
quality sensor. Recirculation is
automatically selected when poor
quality air is detected. The air quality
sensor will not maintain recirculation
for an 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. Touch or press
@to
activate recirculation.
The air quality sensor system does not
protect against carbon monoxide (CO),
which you cannot see or smell. See
Engine Exhaust 0200. The air quality
sensor operation can be adjusted. See
“Climate and Air Quality” under
Vehicle Personalization 0145.
Rear Climate Control
