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
290. 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 electronic
stability control system is
disabled.
ACC can reduce the need for
you to frequently brake and
accelerate, especially when
used on expressways,
freeways, and interstate
highways. When used on other
roads, you may need to take
over the control of braking or
acceleration more often.
{
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
{
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. 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.

When towing a trailer.
