DRL. The 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.
.The vehicle is not in P (Park).

8-6 Climate Controls
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. The fan speed may
slightly increase to help prevent
fogging. 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 on
page 5-40.
Rear Window Defogger
K(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger turns off
automatically after about
10 minutes. If turned on again, it
runs for about five minutes before
turning off. At higher speeds, the
rear window defogger may stay on
continuously. The upper region of gridlines on the
rear window are antenna lines and
are not intended to heat when the
defogger is activated.
If equipped with heated outside
rearview mirrors, they turn on with
the rear window defogger and help
to clear fog or frost from the surface
of the mirror. See
Heated Mirrors on
page 2-20.
{Caution
Using a razor blade or sharp
object on the inside rear window
can damage the antenna or
defogger. Repairs would not be
covered by the vehicle warranty.
Do not stick anything to the rear
window.
Remote Start Climate Control
Operation (If Equipped):
If equipped with remote start, the
climate control system may run
when the vehicle is started remotely.
The system uses the driver ’s previous settings to heat or cool the
inside of the vehicle. The rear defog
may come on during remote start
based on cold ambient conditions.
The rear defog indicator light may
not come on during a remote start.
The front heated seats may turn on
if it is cold outside. The heated seat
indicator lights may not come on
during a remote start. See
Remote
Vehicle Start on page 2-9 and
Heated and Ventilated Seats on
page 1-11 (if equipped).Sensors

recirculation, and air delivery mode
for best comfort.
If the sensor is covered, the
automatic climate control system
may not work properly.Air Vents

9-38 Driving and Operating
your path moving in the same
direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses a radar
sensor. SeeRadio Frequency
Statement on page 13-15.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the Traction Control
System (TCS) or StabiliTrak
®
System activates, the ACC may
automatically disengage. When road
conditions allow ACC to be safely
used, the ACC can be turned back
on. If TCS or StabiliTrak have been
disabled, the ACC will not engage.
See Traction Control/Electronic
Stability Control on page 9-33.
{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 on page 9-3.
{Warning
Adaptive Cruise Control will not
detect or brake for children,
pedestrians, animals, or other
objects.
(Continued)
Warning (Continued)
Do not use Adaptive Cruise
Control 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.
Adaptive Cruise Control
performance is limited under
these conditions.
.On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
