Adaptive Cruise Control - GMC ACADIA 2017 Owner's Manual

246 Driving and Operating
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previous set cruise speed.
While pressing the accelerator pedal
or shortly following the release to
override cruise, briefly applying SET
will result in cruise set to the
current vehicle speed.
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. While on a hill, the
transmission may downshift in order
to use engine braking to slow the
vehicle and maintain the set speed.
Also, you may have to brake or shift
to a lower gear to keep your speed
down. If the brake pedal is applied,
cruise control disengages.
Ending Cruise Control
There are four ways to end cruise
control:
Step lightly on the brake pedal.
Press .
Shift the transmission to
N (Neutral).
Press .
Erasing Speed Memory
The cruise control set speed is
erased from memory if
pressed or if the ignition is
turned off.

Adaptive Cruise Control

If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the following
time between your vehicle and a
vehicle detected directly ahead in
your path, moving in the same
direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses camera
and radar sensors. See Radio
Frequency Statement 0 394.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the Traction Control
System (TCS) or StabiliTrak
electronic stability control system
activates, the ACC may
automatically disengage. See
is
Traction Control/Electronic Stability
Control 0 240. When road
conditions allow ACC to be safely
used, the ACC can be turned
back on.
Turning off the TCS or StabiliTrak
system will disengage the cruise
control.
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
