Toyota Safety Sense C∗
∗: If equipped
The Toyota Safety Sense C consists of the following drive assist
systems and contributes to a safe and comfortable driving expe-
rience:
WARNING
■Toyota Safety Sense C
The Toyota Safety Sense C 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.
