Basic functions
Constant speed cruising
A
When there are no vehicles ahead
The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle
speed display will blink and a buzzer will sound.
Deceleration and follow-up cruising
B
When a preceding vehicle driving slower than the set vehicle
speed is detected
When a vehicle is detected driving ahead of your vehicle, the vehicle auto-
matically decelerates and if a greater reduction in vehicle speed is neces-
sary, the brakes are applied (the stop lights will come on at this time). The
vehicle is controlled to maintain the vehicle-to-vehicle distance set by the
driver, in accordance with changes in the speed of the preceding vehicle. If
vehicle deceleration is not sufficient and the vehicle approaches the vehicle
ahead, the approach warning will sound.
Acceleration

When there are no longer any preceding vehicles driving slower
than the set vehicle speed
The vehicle accelerates until the set vehicle speed is reached and then
resumes constant speed cruising.
