Adaptive Cruise Control
If the lead vehicle is no longer tracked
within a distance of approximately 100 ft
(30 m) and a speed of approximately 20
MPH (30 km/h) or less is detected, a buzzer
sounds single long beep and Adaptive
Cruise Control function is canceled.
At this time, the lead vehicle indicator
flashes.
If the vehicle in front is no longer detected
under conditions other than the previous
ones, the vehicle gradually accelerates back
to the set target vehicle speed and will drive at
that constant speed.
If a vehicle in front is detected while accelerat-
ing to the set target vehicle speed, vehicle
tracking will be started again.
The target vehicle speed can be set between 25 MPH (40 km/h) and 90
MPH (145 km/h).
If the vehicle speed is approximately 25 MPH (40 km/h) or less when the
vehicle speed is set, the set vehicle speed is set to 25 MPH (40 km/h).
When the brakes are applied by Adaptive Cruise Control, the vehicle’'s
brake lights will illuminate.
To temporarily accelerate quickly, use the accelerator pedal. After acceler-
ating, the vehicle will gradually return to the set target vehicle speed shown
in the gauge cluster.
Even if there is no lead vehicle present, on a downhill grade, the Adaptive
Cruise Control’'s automatic brake may operate in order to maintain the set
target vehicle speed.
