Emergency Driving Stop
System
The emergency driving stop
system is a system which
automatically decelerates and
stops the vehicle within its
lane if the driver becomes
unable to continue driving the
vehicle, such as if they have
suffered a medical emergency,
etc.
During LTA (Lane Tracing
Assist) control, if the system
does not detect driving opera-
tions, such as if the driver is
not holding the steering wheel,
and determines the driver is
not responsive, the vehicle will
be decelerated and stopped
within its current lane to help
avoid a collision or reduce the
impact of a collision.
WARNING
■For safe use
●Driving safely is solely the responsi-
bility of the driver. Pay careful atten- tion to the surrounding conditions in order to ensure safe driving. The
emergency driving stop system is designed to provide support in an emergency where it is difficult for
the driver to continue driving, such as if they have had a medical emer-gency. It is not designed to support
driving while drowsy or in poor physical health, or inattentive driv-ing.

5-4. Using the driving support systems
Operation of this system is sepa-
rated 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 determines the
driver is not responsive, it will oper-
ate in control state “deceleration
stop phase” and “stop hold phase”
and decelerate and stop the vehi-
cle. It will then operate continuously
in “stop hold phase”.
■Operating conditions
This system operates when all of the fol- lowing conditions are met:
●When the LTA is on
●When the vehicle speed is approxi-
mately 50 km/h (30 mph) or more
■Operation cancelation conditions
In the following situations, system oper- ation will be canceled:
●When LTA control has been canceled
(the LTA switch has been pressed, etc.)
●When the dynamic radar cruise con-trol 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 operated)
●When the driving assist switch is pressed while in the stop and hold phase
●When the power switch has been turned from ON to OFF
●Situations in which some or all of the
WARNING
●Although the emergency driving stop system is designed to deceler-
ate the vehicle within its lane to help avoid or help reduce the impact of a collision if the system
determines that it is difficult for the driver to continue driving, its effec-tiveness may change according to
various conditions. Therefore, it may not always be able to achieve the same level of performance.
Also, if the operating conditions are not met, this function will not oper-ate.
●After the emergency driving stop system operates, if driving
becomes possible again, immedi- ately begin driving again or, if nec-essary, park the vehicle on the
shoulder of the road and set a warning reflector and flare to warn other drivers of your stopped vehi-
cle.
●After this system operates, passen-
gers should attend to the driver as necessary and take appropriate hazard prevention measures, such
as moving to a place where safety can be ensured, such as the shoul-der of the road or behind a guard-
rail.
●T h i s s y s t e m d e t e c t s t h e c o n d i t i o n o f
the driver through the operation of the steering wheel. This system may operate if the driver is aware
but intentionally 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.

■LTA control when operation is can- celed
When emergency driving stop system
operation is canceled, LTA control may also be canceled.
If driving operations are not
detected after the hands off steer-
ing 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 responsive or
not. If driving operations, such as
holding the steering wheel, are not
performed within a certain amount
of time, the system will enter warn-
ing phase 2.
Vehicles with a driver monitor cam-
era: Depending on the type of
detection of the driver’s unrespon-
siveness, the system may skip
warning phase 1 and start the con-
trol of 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 decelerate. If driving opera-
tions, such as holding the steering
wheel, are not performed within a
certain amount of time, the system
will determine that the driver is not
responsive and enter the decelera-
tion stop phase.
The audio system will be muted until
the driver becomes responsive.
When the vehicle is decelerating, the
brake lights may illuminate, depending
on the road conditions, etc.
After the vehicle has decelerated a cer-
tain amount, the emergency flashers
(hazard lights) will flash.
After the driver is judged as being
not responsive, a buzzer will sound
continuously and a message will be
displayed to warn the driver, and
the vehicle will slowly decelerate
and stop. While the vehicle is
decelerating, the emergency flash-
ers (hazard lights) will flash to warn
other drivers of the emergency.
After the vehicle is stopped, the
parking brake will be applied auto-
matically. After entering the stop
and hold phase, the buzzer will
continue sounding continuously, the
emergency flashers (hazard lights)
will flash to warn other drivers of
the emergency, and the doors will
unlock.

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 sur- roundings.
●The Blind Spot Monitor is a supple-mentary 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 Moni-tor. As the function cannot judge if it
is safe to change lanes, over reli- ance could lead to an accident resulting in death or serious injury.
As the system may not function cor- rectly under certain conditions, the
driver’s own visual confirmation of safety is necessary.

*: If equipped
SEA (Safe Exit Assist)*
The Safe Exit Assist is a sys-
tem that uses radar sensors
installed on the inner side of
the rear bumper to help occu-
pants judge if an approaching
vehicle or bicycle may collide
with a door to reduce the pos-
sibility of a collision.
WARNING
■Cautions regarding the use of
the system
●The driver is solely responsible for safe driving. Always drive safely,
taking care to observe your sur- roundings.
●Safe Exit Assist is a supplementary system that, when the vehicle is stopped, informs occupants of the
existence of approaching vehicles and bicycles. As this system alone cannot be used to judge safety,
over-reliance on this system may lead to an accident resulting in death or serious injury.
As the system may not function cor- rectly under certain conditions, visual confirmation of safety with
the passengers’ own eyes and mir- rors is necessary.
