WARNING
This system detects the condition of
●
the driver through the operation of the
steering wheel. This system may oper-
ate if the driver is aware but intention-
ally and continuously does not operate
the vehicle. Also, the system may not
operate if it cannot determine that the
driver is not responsive, such as if they
are leaning on the steering wheel.

tions in which the driver monitor may
not operate properly :
Summary of the system
Operation of this system is separated
into 4 control states. Through control
state "warning phase 1" and "warning
phase 2", the system determines if the
driver is aware and responsive while
outputting a warning and controlling
the vehicle speed. If the system deter-
mines the driver is not responsive, it will
operate in control state "deceleration
stop phase" and "stop hold phase" and
decelerate and stop the vehicle. It will
then operate continuously in "stop hold
phase".

This system operates when all of the follow-
ing conditions are met:
●
When the LTA is on
Or during the Traffic Jam Assist (if
equipped) controls
●
When the vehicle speed is approximately
30 mph (50 km/h) or more
●
During the Traffic Jam Assist (if
equipped) controls, the system may
operate at below 30 mph (50 km/h).

In the following situations, system operation
6-2. Using the safe driving support functions
will be canceled:
●

LTA control when operation is canceled
■
When emergency driving stop system
operation is canceled, LTA control may also
be canceled.
Warning phase 1
If driving operations are not detected
after the hands off steering wheel
warning operates, a buzzer will sound
intermittently and a message will be
displayed to warn the driver, and the
system will judge if the driver is respon-
sive or not. If driving operations, such
as holding the steering wheel, are not
performed within a certain amount of
time, the system will enter warning
phase 2.
Vehicles with a driver monitor camera:
Depending on the type of detection of
the driver's unresponsiveness, the sys-
tem may skip warning phase 1 and start
the control of warning phase 2.
