■ Operational conditions
The pre-collision system is enabled and determines that the possibility of a
frontal collision with a vehicle is high.
Each function is operational at the following speeds:
● Pre-collision warning:
• Vehicle speed is approximately 15 to 140 km/h (10 to 86 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 15 km/h (10 mph) or more.
● Pre-collision brake assist:
• Vehicle speed is approximately 30 to 80 km/h (19 to 49 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 30 km/h (19 mph) or more.
● Pre-collision braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 49 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 10 km/h (7 mph) or more.
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 the shift lever is in R
● If VSC is disabled (only the pre-collision warning function will be opera-
tional)
■ Cancelation of the pre-collision braking
● If either of the following occur while the pre-collision braking function is
operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is tu rned sharply or abruptly.
● If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the operation of the pre-collision braking function will be canceled
after the vehicle has been stopped for approximately 2 seconds.

surface is uneven or undulating
• When passing a vehicle in an
oncoming lane that is stopped to
make a right/left turn
• When passing an oncoming vehi-
cle while making a left or right turn
• When driving on a road where rel-
