LIGHTING 165
This indicator light turns on in the
instrument cluster when the
high-beam headlamps are on.
Flash-to-Pass
To flash the high beams, pull the turn
signal lever toward you, and release.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day.
If equipped with Light-Emitting Diode
(LED) headlamps, the dedicated DRL
will come on when all of the following
conditions are met:
.The ignition is on.
. The exterior lamp control is
in AUTO. .
The light sensor determines it is
daytime.
When the DRL are on, the taillamps
and other lamps will not be on.
The DRL turn off when the headlamps
are turned to
Oor the ignition is off.
Automatic Headlamp
System
When the exterior lamp control is set
to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it is
light outside when the vehicle leaves
the garage, there is a slight delay
before the automatic headlamp
system changes to the DRL. 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 0167.
When it is bright enough outside, the
headlamps will turn off or may change
to Daytime Running Lamps (DRL).
The automatic headlamp system turns
off when the exterior lamp control is
turned to
Oor the ignition is off.

Press AUTO to return to automatic
operation and the air conditioner runs
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 0152.
@: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 0152.
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 touch screen. To turn the ionizer on or off,
see
“Climate and Air Quality” under
Vehicle Personalization 0152.
Rear Window Defogger
K:Press to turn the rear window
defogger on or off.
The rear window defogger can be set
to automatic operation. See “Climate

Personalization 0152. When Auto Rear
Defog is selected, the rear window
defogger turns on automatically when
the interior temperature is cold and
the outside temperature is about 4 °C
(40 °F) and below.
The upper grid lines 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.

DRIVING AND OPERATING 213
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of the
hills. When going up steep hills, you
might have to step on the accelerator
pedal to maintain your speed. When
going downhill, the cruise control
system may automatically brake to
slow the vehicle down. Also, you may
have to brake or shift to a lower gear
to keep your speed down. If the brake
pedal is applied, cruise control
disengages.
Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal.
. Press
*.
. Shift the transmission to
N (Neutral).
. Press
J.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if
the ignition is turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows for selecting
the cruise control set speed and
following gap. Read this entire section
before using this system. ACC uses a
camera and radar sensors to detect
other vehicles. The following gap is
the following time (or distance)
between your vehicle and a vehicle
detected directly ahead in your path,
moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
limited, moderate braking to maintain
the selected following gap. To
disengage ACC, apply the brake. If the
Traction Control System (TCS) or
StabiliTrak
®electronic stability
control system activates while ACC is
engaged, ACC may automatically
disengage. See Traction Control/
Electronic Stability Control 0208. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC will not engage if the TCS or
StabiliTrak electronic stability control
system is disabled.
{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver”
in this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0185.

214 DRIVING AND OPERATING
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:. On winding and hilly roads or
when the sensors are blocked
by snow, ice, or dirt. The
system may not detect a
vehicle ahead. Keep the entire
front of the vehicle clean.
. Visibility is low, such as in
fog, rain, or snow conditions.
ACC performance is limited
under these conditions.
. On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
J:Press to turn the system on or
off. The indicator turns white on the
instrument cluster when ACC is
turned on.
RES+ : Press briefly to resume the
previous set speed or to increase
vehicle speed if ACC is already
engaged. To increase speed by 1 km/h
(1 mph), press RES+ to the first detent.
To increase speed to the next 5 km/h
(5 mph) mark on the speedometer,
press RES+ to the second detent.
SET– :Press briefly to set the speed
and activate ACC or to decrease
vehicle speed if ACC is already
engaged. To decrease speed by 1 km/h (1 mph), press SET−
to the first detent.
To decrease speed to the next 5 km/h
(5 mph) mark on the speedometer,
press SET− to the second detent.
*:Press to disengage ACC without
erasing the selected set speed.
[: Press to select a following gap
time (or distance) setting for ACC of
Far, Medium, or Near.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster (Base
Level) 0115 orInstrument Cluster
(Uplevel) 0118. The increment value
used depends on the units displayed.
