WARNING

Limitations of the pre-crash safety system
Do not overly rely on the pre-crash safety system. Always drive safely, taking
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 pro-
vide, 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 avail-
able to the pre-crash safety system is that from obstacles it has detected
directly in front of the vehicle. Therefore, it is absolutely necessary 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.
