The Toyota Safety Sense 3.0
consists of the driving
assist systems and contrib-
utes to a safe and comfort-
able driving experience:
WARNING
■Toyota Safety Sense 3.0
The Toyota Safety Sense 3.0
operates under the assumption
that the driver will drive safely,
and is designed to help reduce
the impact to the occupants in a
collision and assist the driver
under normal driving conditions.
As there is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not ov erly rely on this
system. The driver is solely
responsible for paying attention to
the vehicle’s surroundings and
driving safely.
■For safe use
●Do not overly rely on this sys-
tem. The driver is solely respon-
sible for paying attention to the
vehicle’s surroundings and driv-
ing safely. This system may not
operate in all situations and pro-
vided assistance is limited.
Over-reliance on this system to
drive the vehicle safely may
lead to an accident resulting in
death or serious injury.
●Do not attempt to test the oper-
ation of the system, as it may
not operate properly, possibly
leading to an accident.
●If attention is necessary while
performing driving operations or
a system malfunction occurs, a
warning message or warning
buzzer will be operated. If a
warning message is displayed
on the display, follow the
instructions displayed.
●Depending on external noise,
the volume of the audio system,
etc. it may be difficult to hear the
warning buzzer. Also, depend-
ing on the road conditions, it
may be difficult to recognize the
operation of the system.
■When it is necessary to dis-
able the system
In the following si tuations, make
sure to disable the system.
Failure to do so may lead to the
system not operating properly,
possibly leading to an accident
resulting in death o r serious injury.
●When the vehicle is tilted due to
being overloaded or having a
flat tire
●When driving at extremely high
speeds
●When towing another vehicle
●When the vehicle is being trans-
ported by a truck, ship, train,
etc.
●When the vehicle is raised on a
lift and the tires are allowed to
rotate freely
●When inspecting the vehicle
using a drum tester such as a
chassis dynamometer or speed-
ometer tester, or when using an
on vehicle wheel balancer
●When the vehicle is driven in a
sporty manner or off-road
