ACC Automatically Disengages
ACC may automatically disengage and
you will need to manually apply the
brakes to slow the vehicle when:
The sensors are blocked.
The Traction Control System (TCS)
or StabiliTrak/ESC system has
activated or been disabled.
There is a fault in the system.
The radar falsely reports blockage
when driving in a desert or remote
area with no other vehicles or
roadside objects.
A DIC message may display to
indicate that ACC is temporarily
unavailable.
The ACC indicator will turn white
when ACC is no longer active.
In some cases, when ACC will not
activate, regular Cruise Control may
be used. See Switching Between ACC
and Regular Cruise Control previously
in this section. Always consider
driving conditions before using either
cruise control system.
Notification to Resume ACC
ACC will maintain a follow gap behind
a detected vehicle and slow your
vehicle to a stop behind that vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead indicator
will flash as a reminder to check
traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three
times, or three beeps will sound. See
Alert Type and Adaptive Cruise Go
Notifier in Collision/Detection
Systems under Vehicle Personalization
0 118.
When the vehicle ahead drives away,
ACC resumes automatically if the stop
was brief. If necessary, press RES+ or
DRIVING AND OPERATING
the accelerator pedal to resume ACC.
If stopped for more than two minutes
or if the driver door is opened and the
driver seat belt is unbuckled, the ACC
automatically applies the Electric
Parking Brake (EPB) to hold the
vehicle. The EPB status light will turn
on. See Electric Parking Brake 0 234.
To release the EPB, press the
accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle.
Warning
If ACC has stopped the vehicle, and
if ACC is disengaged, turned off,
or canceled, the vehicle will no
longer be held at a stop. The vehicle
can move. When ACC is holding the
vehicle at a stop, always be
prepared to manually apply the
brakes.
