Lighting 6-5
headlamp system turns off the
headlamps. During that delay, the
instrument cluster may not be as
bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control on page 6-6.
When it is bright enough outside,
the headlamps will turn off Daytime
Running Lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned to
Oor the ignition
is off.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are not operating, these lamps turn off.
Move the exterior lamp control to
O
or;to disable this feature.
Adaptive Forward
Lighting (AFL)
On vehicles with the AFL system,
the headlamps pivot horizontally to
provide greater road illumination
while turning. To enable AFL, set
the exterior lamp control on the turn
signal lever to the AUTO position.
Moving the control out of the AUTO
position will deactivate the system.
AFL will operate when the vehicle
speed is greater than 3 km/h
(2 mph). AFL will not operate when
the transmission is in R (Reverse).
AFL is not immediately operable
after starting the vehicle; driving a
short distance is required to
calibrate the AFL. See

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.

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.
