When driving
RX350/270_EE
CAUTION
■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 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-visibil-
ity conditions. It is still necessary for the driver to pay close attention to the vehi-
cle’s surroundings.
●Assisting the driver in making correct judgment
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 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 col-
lision 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 encoun-
tering a dangerous situation the driver must take direct and immediate action in
order to ensure the safety of all involved.
