WARNING
Pre-collision braking
■
When the pre-collision braking function is operating, a large amount of braking force
●
will be applied.
If the vehicle is stopped by the operation of the pre-collision braking function, the
●
pre-collision braking function operation will be canceled after approximately 2 sec-
onds. Depress the brake pedal as necessary.
The pre-collision braking function may not operate if certain operations are per-
●
formed by the driver. If the accelerator pedal is being depressed strongly or the steer-
ing wheel is being turned, the system may determine that the driver is taking evasive
action and possibly prevent the pre-collision braking function from operating.
In some situations, while the pre-collision braking function is operating, operation of
●
the function may be canceled if the accelerator pedal is depressed strongly or the
steering wheel is turned and the system determines that the driver is taking evasive
action.
If the brake pedal is being depressed, the system may determine that the driver is tak-
●
ing evasive action and possibly delay the operation timing of the pre-collision braking
function.
