242 Driving and Operating
Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
Vehicles in front of your vehicle that have
a rear aspect that is low, small,
or irregular
An empty truck or trailer that has no
cargo in the cargo bed
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
Vehicles that are low to the road surface
Objects that are close to the front of your
vehicle
Vehicles on which extremely heavy cargo
is loaded in the cargo area or rear seat
ACC Automatically Disengages
ACC may automatically disengage and the
driver will need to manually apply the
brakes to slow the vehicle if:
The front camera is blocked or visibility is
reduced.
The Traction Control System (TCS) or
StabiliTrak/ESC system has activated or
been disabled.
There is a fault in the system.
A DIC message displays to indicate that
ACC is temporarily unavailable.
The ACC indicator will turn white when ACC
is no longer active.
In some cases, when ACC is temporarily
unavailable, 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 (if equipped) will pulse
three times, or three beeps will sound. To
view available settings from the
infotainment screen, touch Settings >
Vehicle > Collision/Detection Systems > Alert
Type > Adaptive Cruise Go Notifier.
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 0 228. 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 Vehicle Messages 0 134.
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.
