Lighting Features
Entry Lighting
The headlamps, taillamps, back-up
lamps, license plate lamps, dome
lamps, and most of the interior lights
turn on briefly at night when
Kis
pressed on the Remote Keyless
Entry (RKE) transmitter. See Ignition
Positions on page 9-16. After about
30 seconds the exterior lamps turn
off, then the dome and remaining
interior lamps dim to off. Entry
lighting can be disabled manually by
changing the ignition out of the OFF
position, or by pressing
Qon the
RKE transmitter.
This feature can be turned on or off.
See “Vehicle Locator Lights” under
Vehicle Personalization on
page 5-47.
Exit Lighting
The headlamps, taillamps, back-up
lamps, parking lamps, and license
plate lamps come on at night, or in
areas with limited lighting, when the
key is removed from the ignition.
The dome lamps also come on
when the key is removed from the
ignition. The exterior lamps and
dome lamps remain on after the
door is closed for a set amount of
time, then automatically turn off.
If equipped with Keyless Access,
the exterior lamps and dome lamps
automatically turn on when the
driver door is opened after the
ignition is turned off. See Ignition
Positions on page 9-16.
The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalization on
page 5-47.
Battery Load
Management
The vehicle has Electric Power
Management (EPM), which
estimates the battery's temperature
and state of charge. It then adjusts
the voltage for best performance
and extended life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a 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 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 messageis displayed, it is recommended that
the driver reduce the electrical loads
as much as possible. See
Driver
Information Center (DIC) on
page 5-29.
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
position.

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

Climate Controls 8-5
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

Vehicle Personalization on
page 5-47. 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 region of 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
Do not try to clear frost or other
material from the inside of the

8-6 Climate Controls
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.
Press the AUTO button on the
climate control to activate the air
quality sensor. The recirculation
indicator light comes on 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. 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 on
page 9-22. The air quality sensor
operation can be adjusted, See “Climate and Air Quality”
under
Vehicle Personalization on
page 5-47.
Rear Climate Control
System
If equipped, the rear climate control
system is on the rear of the center
console. The settings can be
adjusted with the rear climate
control buttons and the touch
screen.
