Driving and Operating
.
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is no longer active.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 is temporarily
unavailable, regular cruise control may be
used. See
“
Switching Between ACC and
Regular Cruise Control
”
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. Touch the
Settings icon on the infotainment home
page. Select
“
Vehicle
”
to display the list of
available options and select
”
Alert Type
”
and
“
Adaptive Cruise Go Notifier
”
in
“
Collision/
Detection Systems
”
.
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
unfastened, the ACC automatically applies
the Electric Parking Brake (EPB) to hold the
vehicle. The EPB status light will turn on.
See
. To release
the EPB, depress the accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before exiting
the vehicle. See
{
Warning
If ACC has stopped the vehicle, and if ACC
is disengaged, turned off, or cancelled,
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.
{
Warning
Leaving the vehicle without placing it in
P (Park) can be dangerous. Do not leave
the vehicle while it is being held at a
stop by ACC. Always place the vehicle in
P (Park) and turn off the ignition before
leaving the vehicle.
ACC Override
If using the accelerator pedal while ACC is
active, the ACC indicator turns blue on the
instrument cluster and in the HUD (if
equipped) to indicate that automatic braking
will not occur. ACC will resume operation
when the accelerator pedal is not being
pressed.
{
Warning
The ACC will not automatically apply the
brakes if your foot is resting on the
accelerator pedal. You could crash into a
vehicle ahead of you.
