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.

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

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
J is
pressed or if the ignition is
turned off. Adaptive Cruise Control If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the following
time 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. ACC uses camera
and radar sensors. See Radio
Frequency Statement 0 371 .
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 ®
electronic stability control system
activates, the ACC may automatically disengage. See
Traction Control/Electronic Stability
Control 0 217 . 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.
{ WarningACC 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 0 193 .
