Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14590481) - 2021 - CRC - 6/2/20
DRIVING AND OPERATING 253
Warning (Continued)
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when ACC is no longer active.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.
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
0 124.
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 0 240.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0 124.

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.
