Operational conditions
The pre-crash safety system is enabled and determines that the possibility of
a frontal collision with a vehicle (except motorcycles and bicycles) is high.
●
Pre-crash warning:
• Vehicle speed is approximately 15 to 140 km/h (10 to 86 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 15 km/h (10 mph).
●
Pre-crash brake assist:
• Vehicle speed is approximately 30 to 80 km/h (19 to 49 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 30 km/h (19 mph).
● Pre-crash braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 49 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 10 km/h (7 mph).
The system may not operate in the following situations:
●
If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time
●
If VSC is disabled (only the pre-crash warning function will be operational)
● If the PCS warning light is flashing or illuminated
■
Cancelation of the pre-crash braking
●
If either of the following situations occur while the pre-crash braking function
is operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
●
If the vehicle is stopped by the operation of the pre-crash braking function,
the operation of the pre-crash braking function will be canceled after the
vehicle has been stopped for approximately 2 seconds.
