Driving
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 determines the
driver is not responsive, it will
operate in control state “Decel-
eration stop phase” and “Stop
hold phase” and decelerate and
stop the vehicle. It will then
operate continuously in “Stop
hold phase”.
■Operating conditions
This system opera tes when all of
the following cond itions are met:
●When the LTA is on
●When the vehicle speed is
approximately 30 mph (50 km/h)
or more
■Operation cancelation condi-
tions
In the following si tuations, system
operation will be canceled:
●When LTA control has been can-
celed (the LTA switch has been
pressed, etc.)
●When the dynamic radar cruise
control has been canceled
●When driver operations are
detected (the steering wheel is
held, the brake pedal, accelerator
pedal, parking brake, hazard light
switch, or turn sig nal lever is oper-
ated)
●When the driving assist switch is
pressed while in the stop and hold
phase
●When the power s witch has been
turned from ON to off
●Situations in whic h some or all of
the functions of the system cannot operate:
P. 2 1 2
■LTA control when operation is
canceled
When emergency driving stop sys-
tem operation is canceled, LTA con-
trol may also be canceled.
If driving operations are not
detected after the hands off
steering wheel warning oper-
ates, a buzzer will sound inter-
mittently and a message will be
displayed to warn the driver, and
the system will judge if the driver
is responsive or not. If driving
operations, such as holding the
steering wheel, are not per-
formed within a certain amount
of time, the system will enter
warning phase 2.
After entering warning phase 2,
a buzzer will sound in short
intervals and a message will be
displayed to warn the driver, and
the vehicle will slowly deceler-
ate. If driving operations, such
as holding the steering wheel,
are not performed within a cer-
tain amount of time, the system
will determine that the driver is
not responsive and enter the
deceleration stop phase.
The audio system will be muted
until the driver becomes respon-
sive.
When the vehicle is decelerating,

etc.
After entering the deceleration
stop phase, a buzzer will sound
continuously and a message will
be displayed to warn the driver,
and the vehicle will slowly decel-
erate and stop. After the vehicle
stops, the system will enter the
stop and hold phase.
After the vehicle is stopped, the
parking brake will be applied
automatically. After entering the
stop and hold phase, the buzzer
will continue sounding continu-
ously and the emergency flash-
ers (hazard lights) will flash to
warn other drivers of the emer-
gency.
■Restricted functions after the
operation is canceled
After shifting to the deceleration
stop phase, the following functions
will not be available until the hybrid
system is re-started even though the
emergency driving stop system is
canceled:

BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on
the inner side of the rear
bumper on the left and right
side to assist the driver in
confirming safety when
changing lanes.
WARNING
■Cautions regarding the use of
the system
●The driver is solely responsible
for safe driving. Always drive
safely, taking care to observe
your surroundings.
●The Blind Spot Monitor is a sup-
plementary function which alerts
the driver that a vehicle is in a
blind spot of the outside rear
view mirrors or is approaching
rapidly from behind into a blind
spot. Do not overly rely on the
Blind Spot Monitor. As the func-
tion cannot judge if it is safe to
change lanes, over reliance
could lead to an accident result-
ing in death or serious injury. As
the system may not function
correctly under certain condi-
tions, the driver’s own visual
confirmation of safety is neces-
sary.
