WARNING
Limitations of the pre-crash safety system
■
The driver is solely responsible for safe driving. Always drive safely, taking care to
●
observe your surroundings.
Do not use the pre-crash safety system instead of normal braking operations under
any circumstances. This system will not prevent collisions or lessen collision damage
or injury in every situation. Do not overly rely on this system. Failure to do so may lead
to an accident, resulting in death or serious injury.
Although this system is designed to help avoid a collision or help reduce the impact of
●
the collision, its effectiveness may change according to various conditions, therefore
the system may not always be able to achieve the same level of performance.
Read the following conditions carefully. Do not overly rely on this system and always
drive carefully.
• Conditions under which the system may operate even if there is no possibility of a
collision: P. 279
• Conditions under which the system may not operate properly: P. 282
Do not attempt to test the operation of the pre-crash safety system yourself.
●
Depending on the objects used for testing (dummies, cardboard objects imitating
detectable objects, etc.), the system may not operate properly, possibly leading to an
accident.
Pre-crash braking
■
When the pre-crash braking function is operating, a large amount of braking force
●
will be applied.
If the vehicle is stopped by the operation of the pre-crash braking function, the pre-
●
crash braking function operation will be canceled after approximately 2 seconds.
Depress the brake pedal as necessary.
The pre-crash braking function may not operate if certain operations are performed
●
by the driver. If the accelerator pedal is being depressed strongly or the steering
wheel is being turned, the system may determine that the driver is taking evasive
action and possibly prevent the pre-crash braking function from operating.
In some situations, while the pre-crash braking function is operating, operation of the
●
function may be canceled if the accelerator pedal is depressed strongly or the steer-
ing 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-crash braking
function.
