Approaching and Following a Vehicle
The vehicle ahead indicator light is displayed
in the instrument cluster and the HUD,
if equipped. It only displays when a vehicle
is detected in your vehicle’s path and is
moving in the same direction. If the vehicle
ahead indicator light does not appear in the
instrument cluster, then ACC will not
respond to, or brake for, vehicles ahead.
While ACC is active, ACC will automatically
adjust your vehicle’s speed to follow a
detected vehicle ahead according to the
selected following gap setting. ACC may
decrease your vehicle’s cruise speed when
following a detected vehicle ahead that is
traveling slower than your ACC set speed.
ACC may apply limited braking, if necessary.
When ACC automatic braking is active, the
brake lamps will turn on. The automatic
braking may feel or sound different than if
the brakes were applied manually. This is
normal.
Passing a Vehicle While Using ACC
If the set speed is high enough, and the left
turn signal is used to pass a vehicle ahead
in the selected following gap, ACC may
assist by gradually accelerating the vehicle
prior to the lane change.
