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 0 355.
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 electronic stability
control system activates, the ACC
may automatically disengage. See
Traction Control/Electronic Stability
Control 0 203. When road
conditions allow ACC to be safely
used, the ACC can be turned
back on.
ACC will not engage if the TCS or
StabiliTrak electronic stability control
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
stop ahead, or enter your lane.
Also see Alerting the Driver in
this section. Complete attention is
always required while driving and
you should be ready to take
action and apply the brakes. See
Defensive Driving 0 180.
Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
On winding and hilly roads
or when the sensors are
blocked by snow, ice, or dirt.

Driving and Operating
Warning (Continued)
The system may not detect
a vehicle ahead. Keep the
entire front of the vehicle
clean.
Visibility is low, such as in
fog, rain, or snow
conditions. ACC
performance is limited under
these conditions.
On slippery roads where
fast changes in tire traction
can cause excessive
wheel slip.
