Alert (FCA) feature. See Forward
Collision Alert (FCA) System on
page 9‑53.
Alerting the Driver
If ACC is engaged, driver action
may be required when:
.
ACC cannot apply sufficient
braking because of approaching
a vehicle too rapidly.
.
A temporary condition prohibits
ACC from operating. See
Vehicle Messages on page 5‑30.
.
A malfunction is detected in the
system. See Vehicle Messages
on page 5‑30.
When any of these conditions occur,
the collision alert symbol on the
HUD will flash on the windshield.
Either eight beeps will sound from
the front, or both sides of the Safety
Alert Seat will pulse five times. See
“Collision/Detection Systems” under
Vehicle Personalization on
page 5‑41.
See Defensive Driving on page 9‑3.
Approaching and Following a
Vehicle

instrument cluster and HUD display
(if equipped).
The vehicle ahead symbol only

in your vehicle’s path.
If this symbol is not displaying, ACC
will not respond to or brake to
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle
speed increases or decreases to
follow the vehicle in front of you, but
will not exceed the set speed. It may
apply limited braking, if necessary.
When braking is active, the brake
lamps will come on. The automatic
braking may feel or sound different
than if the brakes were applied
manually. This is normal.

traffic or when a vehicle suddenly
