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
■
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.
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. (
