Approaching and Following a
Vehicle
The vehicle ahead symbol is in the
instrument cluster and HUD display
(if equipped).
The vehicle ahead symbol only
displays when a vehicle is detected
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
lights will come on. The automatic
braking may feel or sound different
than if the brakes were applied
manually. This is normal.
