Stationary or Very Slow-Moving
Objects
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.
Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
Vehicles with cargo extending from
the back end.
Non-standard shaped vehicles, such
as vehicle transport, vehicles with a
side car fitted, or horse carriages.
Objects that are close to the front of
your vehicle.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when:
The sensors are blocked.
The Traction Control System (TCS)
or StabiliTrak/ESC 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 active symbol 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when ACC is no longer active.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.
DRIVING AND OPERATING
Notification to Resume ACC
ACC will maintain a following 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
0 126.
When the vehicle ahead drives away,
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, ACC automatically applies
the Electric Parking Brake (EPB) to
hold the vehicle. The Electric Parking
Brake light will turn on. See Electric
Parking Brake 0 228.
