4-5. Using the driving support systems
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 opera-
tions 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 vari-
ous 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 pos-
sibility of a collision: →P. 314
• Conditions under which the system may not operate properly: →P. 316
●
Do not attempt to test the operation of the pre-crash safety system your-
self, as the system may not operate properly, possibly leading to an acci-
dent.
■
Pre-crash braking
●
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, oper-
ation 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-crash braking
function is operating. As the pre-crash 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 taking evasive action and possibly delay the operation timing of
the pre-crash braking function.
