Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a vehicle
it has never detected moving. This
can occur in stop-and-go traffic or
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
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 electronic stability control
system has activated or been
disabled.
.
No traffic or other objects are
being detected.
.
There is a fault in the system.
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when ACC is no longer active.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
0 170 .
When the vehicle ahead drives away,
ACC resumes automatically if the stop
was brief. If necessary, press RES+ or
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 0 235 .
To release the EPB, press the
accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See
