Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows for selecting
the cruise control set speed and
following gap. Read this entire
section before using this system.
ACC uses a radar sensor to detect
other vehicles. See Radio
Frequency Statement 0345. The
following gap is the following time
(or distance) 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.
If a vehicle is detected in your path,
ACC can speed up the vehicle or
apply limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If the Traction Control System (TCS)
or StabiliTrak/Electronic Stability
Control (ESC) system activates
while ACC is engaged, ACC may
automatically disengage. See
Traction Control/Electronic Stability
Control
0196. When road
conditions allow ACC to be safely
used, ACC can be turned back on.
ACC will not engage if the TCS or
StabiliTrak/ESC system is disabled.
{Warning
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
