CAUTION
Limitations of the pre-crash safety system
Do not overly rely on the pre-crash safety system. Always drive safely, tak-
ing care to observe your surroundings and checking for any obstacles or
other road hazards.
Failure to do so may cause an accident resulting in death or serious injury.
Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-crash safety system is
intended to assist the driver in avoiding collisions through the process of
LOOK-JUDGE-ACT. There are limits to the degree of assistance the system
can provide, so please keep in mind the following important points.
Assisting the driver in watching the road
The pre-crash safety system is only able to detect obstacles directly in
front of the vehicle, and only within a limited range. It is not a mechanism
that allows careless or inattentive driving, and it is not a system that can
assist the driver in low-visibility conditions. It is still necessary for the
driver to pay close attention to the vehicle’s surroundings.
Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data
available to the pre-crash safety system is that from obstacles it has
detected directly in front of the vehicle. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there
is a possibility of collision in any given situation.
Assisting the driver in taking action
The pre-crash safety system’s braking assist feature is designed to help
reduce the severity of a collision, and so only acts when the system has
judged that a collision is unavoidable. This system by itself is not capable
of automatically avoiding a collision or bringing the vehicle to a stop
safely. For this reason, when encountering a dangerous situation the driver
must take direct and immediate action in order to ensure the safety of all
involved.
