Operational conditions
■
The pre-crash safety system is enabled and the system determines that the
possibility of a frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:
Pre-crash warning:
●
• Vehicle speed is between approximately 10 and 180 km/h (7 and
110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 10 and 80 km/h [7 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 10 km/h (7 mph) or more.
Pre-crash brake assist:
●
• Vehicle speed is between approximately 30 and 180 km/h (20 and
110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 30 and 80 km/h [20 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 30 km/h (20 mph) or more.
Pre-crash braking:
●
• Vehicle speed is between approximately 10 and 180 km/h (7 and
110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 10 and 80 km/h [7 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 10 km/h (7 mph) or more.
The system may not operate in the following situations:
If a 12-volt battery terminal has been disconnected and reconnected and
●
then the vehicle has not been driven for a certain amount of time
If the shift position is in R
●
If VSC is disabled (only the pre-crash warning function will be operational)
●
Pedestrian detection function
■
The pre-crash safety system detects
pedestrians based on the size, profile,
and motion of a detected object. However,
a pedestrian may not be detected
depending on the surrounding brightness
and the motion, posture, and angle of the
detected object, preventing the system
from operating properly. (P. 221)
Cancelation of the pre-crash braking
■
If either of the following occur while the pre-crash braking function is operat-
ing, it will be canceled:
The accelerator pedal is depressed strongly.
●
The steering wheel is turned sharply or abruptly.
