TOYOTA SAFETY SENSE
ADJUSTING DISTANCE
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 328 ft (100 m) ahead, determines the current vehicle-to-vehicle
following distance and operates to maintain a preset following distance from the
vehicle ahead. These distances vary based on vehicle speed.
Note: Vehicle-to-vehicle distance will close in when traveling on long downhill slopes.
(1)
(1) Constant speed cruising when there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle distance
control.
(2) Deceleration cruising and follow-up cruising when a preceding vehicle
driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the brake lights will come on at this
time). The system will respond to changes in the speed of the vehicle ahead
in order to maintain the vehicle-to-vehicle distance set by the driver. A warning
tone warns you when the system cannot decelerate sufficiently to prevent your
vehicle from closing in on the vehicle ahead.
(3) Acceleration when there are no longer any preceding vehicles driving
slower than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Note: When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, the display will flash and the buzzer
will sound to alert the driver. An example of this would be if another driver cuts in
front of you while you are following a vehicle. Depress the brake pedal to ensure an
appropriate vehicle-to-vehicle distance.
