If there is no vehicle ahead, the vehicle will maintain the set
speed. If a slower moving vehicle is detected in the same
lane, the instrument cluster display will show the “Sensed
Vehicle Indicator” icon, and the system will adjust the
vehicle speed automatically to maintain the distance set-
ting, regardless of the set speed.
The vehicle will then maintain the set distance until:
The vehicle ahead accelerates to a speed above the set
speed.
The vehicle ahead moves out of your lane or view of the
sensor.
The distance setting is changed.
The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE: The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to maintain
the set distance. If this occurs, a visual alert “BRAKE” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.
NOTE: The “Brake!” Screen in the instrument cluster
display is a warning for the driver to take action and does
not necessarily mean that the Forward Collision Warning
system is applying the brakes autonomously.
