WARNING
■
Pre-collision braking
*
3
●
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.
●
A large amount of braking force is applied while the pre-collision braking function is
operating. As the pre-collision braking function will be canceled after the vehicle has
been stopped for approximately 2 seconds, the driver should depress the brake
pedal as necessary.
●
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.

: Depending on the region in which the vehicle was sold, the pre-collision braking
function may not be available.
