Other functions
■ "Obstacle Detected" warning
The "Obstacle detected" warning is activated while Adaptive Cruise Control is following a
lead vehicle. This function warns the driver when it determines that the current level of
deceleration by automatic braking control is insufficient.
When the system determines that the vehi-
cle speed needs to be reduced manually by
the driver, the "Obstacle Detected" warning
will be displayed in the combination meter
display and a warning buzzer will sound
several short beeps.
When this function activates, depress the
brake pedal to decelerate and maintain a
correct following distance.
If the buzzer sounds frequently, do not use Adaptive Cruise Control.
The "Obstacle Detected" warning will not activate in the following situa-
tions.
- The accelerator pedal is depressed.
- The brake pedal is depressed.
Even when the following distance is short, the "Obstacle Detected" warn-
ing may not activate in the following situations.
- The difference in speed with the vehicle in front is small. (The two vehi-
cles are travelling at almost the same speed.)
- The vehicle in front is traveling faster than your vehicle. (The following
distance is gradually increasing.)
- Another vehicle cuts into your lane very close to your vehicle.
- The vehicle in front decelerates suddenly.
- When there are repeated uphill and downhill grades
The "Obstacle Detected" warning may not activate in time in the case of a
vehicle that is stopped at the end of a line at a toll gate, at a stop light or inter-
section or in traffic congestion, or a vehicle that is moving much slower than
your vehicle. EyeSight requires a speed differential in order to recognize a
potential obstacle and react to it.
