properly, the surrounding conditions
as recognized by the driver and
detected by the system may differ.

ensure safety. Over-reliance on this
system to drive the vehicle safely may
lead to an accident resulting in death
or serious injury.
● While the Traffic Jam Assist function is
operating, as driver operation may
become necessary, the driver must
ensure they have clear visibility of their
surroundings.
● In certain situations, a message urging
the driver to hold the steering wheel
may be displayed by the Traffic Jam
Assist function. In this case, hold the
steering wheel and drive the vehicle
manually to ensure safety.

detect the following objects. Operate
the steering wheel, accelerator pedal,
