■Hands off steering wheel warn-
ing operation
In the following situations, a mes-
sage urging the dr iver to grip the
steering wheel and the icon shown
in the illustration will be displayed on
the display to warn the driver. If the
system detects that the steering
wheel is held, the warning will be
canceled. When using the system,
make sure to grip the steering wheel
firmly, regardless of whether the
warning is operating or not.
●When the system determines the
driver is not holding the steering
wheel while the lane centering
function is operating
If no operations are detected for a
certain amount of time, a buzzer will
sound, the warnin g will operate.
This warning may also operate if the
driver only operates steering wheel
a small amount continuously.
■Warning operation after preced-
ing vehicle deceleration assis-
tance has ended
After preceding vehicle decelera-
tion assistance has ended, if the
driver does not operate the brake
pedal or accelerator pedal and the vehicle approaches the preceding
vehicle, the displa
y will flash and a
buzzer will sound to urge the driver
to decelerate. If the system deter-
mines that the driver is operating the
brake pedal or accelerator pedal,
the warning will be canceled.

and the system cannot provide
sufficient deceleration, such as
if a vehicle cuts in front of the
vehicle, a warning display will
flash and a buzzer will sound to
alert the driver. Depress the
brake pedal to ensure appropri-
ate vehicle-to-vehicle distance.
■Warnings may not occur
when
In the following situations, the
warning may not operate even
though the vehicle-to-vehicle
distance is short.
 When the preceding vehicle is
traveling at the same speed
or faster than your vehicle
 When the preceding vehicle is
traveling at an extremely low
speed
 Immediately after the vehicle
speed has been set
 When the accelerator pedal is
depressed
When a curve is detected, the
vehicle speed will begin being
reduced. When the curve ends,
the vehicle speed reduction will
end.
Depending on the situation, the
vehicle speed will then return to the
set vehicle speed.
In situations where vehicle-to-vehi-
cle distance control needs to oper- ate, such as when a preceding
vehicle cuts in front of your vehicle,
the curve speed reduction function
will be canceled.
■Situations in which the curve
speed reduction function may
not operate
In situations such as the following,
the curve speed reduction function
may not operate:
●When the vehicle is being driven
around a gentle curve
●When the accele rator pedal is
being depressed
●When the vehicle is being driven
around an extremely short curve
If your vehicle is being driven at
approximately 50 mph (80 km/h)
or more and a lane change to
the passing lane is performed,
when the turn signal lever is
operated and the lane is
changed, the vehicle will accel-
erate up to the set speed to
assist in overtaking.
The system’s recognition of which
lane is the passing lane may be
based solely on the location of the
steering wheel in the vehicle
(left-hand drive/right-hand drive). If

the vehicle is driven in a location
where the passing lane is on the
opposite side of that where the
vehicle was originally sold, the
vehicle may accelerate when the
turn signal lever is operated away
from the passing lane. (e.g. The
vehicle was manufactured for a
right-hand traffic location, but is
being driven in a left-hand traffic
location. The vehicle may acceler-
ate when the turn signal lever is
operated to the right.)
If your vehicle is being driven at
approximately 50 mph (80 km/h) or
more and the lane is changed to
that with a vehicle traveling slower
than your vehicle, when the turn
signal lever is operated the vehicle
will gradually decelerate to assist in
changing lanes.
 The settings of Dynamic radar
cruise control can be changed
through customize settings.

on highways and express-
ways.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver.
Therefore, do not overly rely on
this system. The driver is solely
responsible for paying attention
to the vehicle’s surroundings
and driving safely.
●Set the speed appropriately
according to the speed limit,
traffic flow, road conditions,
weather conditions, etc. The
driver is responsible for confirm-
ing the set speed.
■Situations in which cruise
control should not be used
Do not use the cruise control in
the following situ ations. As the
system will not be able to provide
appropriate control, using it may
lead to an acciden t resulting in
death or serious injury.
●On roads with sharp bends
●On winding roads
●On slippery roads, such as
those covered with rain, ice or
snow
●On steep downhills, or where
there are sudden changes
between sharp up and down
gradients

2044-5. Using the driving support systems
Operation of this system is sep-
arated into 4 control states.
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 medi-
cal emergency, etc.
During LTA (Lane Tracing
Assist) control, if the sys-
tem does not detect driving
operations, such as if the
driver is not holding the
steering wheel, and deter-
mines 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 colli-
sion.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attention to the sur-
rounding conditions in order to
ensure safe driving. The emer-
gency driving stop system is
designed to provide support in
an emergency where it is diffi-
cult for the driver to continue
driving, such as if they have had
a medical emergency. It is not
designed to support driving
while drowsy or in poor physical
health, or inattentive driving.
●Although the emergency driv-
ing stop system is designed to
decelerate 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 con-
tinue driving, its effectiveness
may change according to vari-
ous conditions. Therefore, it
may not always be able to
achieve the same level of per-
formance. Also, if the operating
conditions are not met, this
function will not operate.
●After the emergency driving
stop system operates, if driving
becomes possible again, imme-
diately begin driving again or, if
necessary, park the vehicle on
the shoulder of the road and set
a warning reflecto r and flare to
warn other drivers of your
stopped vehicle.
●After this system operates, pas-
sengers 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 shoulder
of the road or behind a guard-
rail.
●This system detects the condi-
tion of the driver through the
operation of the steering wheel.
This system may operate if the
driver is aware but intentionally
and continuously does not oper-
ate 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.
