Driving and Operating
ACC may automatically disengage. See
Traction Control/Electronic Stability Control
. When road conditions allow ACC to
be safely used, ACC can be turned back on.
Disabling the TCS or StabiliTrak/ESC system
will disengage and prevent engagement
of ACC
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
.
{
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
