WARNING
■Toyota Safety Sense P
The Toyota Safety Sense P is designed to operate under the assumption
that the driver will drive safely, and is designed to help reduce the impact to
the occupants and the vehicle in the case of a collision or assist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle’s surround-
ings and driving safely.
