Driving
PDA (Proactive driv-
ing assist)
When a detectable object
(P.212) is detected, the
proactive driving assist
operates the brakes and
steering wheel to help pre-
vent the vehicle from
approaching too close to
the object.
WARNING
■For safe use
Driving safely is solely the respon-
sibility of the driver.
●The proactive driving assist is
designed to provide some
assistance for regular braking
and steering operations, as well
as helping to prevent the vehicle
from approaching too close to a
detectable object. However, the
scope of this assistance is lim-
ited.
The driver should perform brake
and steering operations as neces-
sary. Read the following items
carefully. Do not overly rely on the
proactive driving assist and
always drive carefully.( P.213)
●The proactive driving assist is
not a system which reduces the
amount of attention necessary
for safe driving. Even if the sys-
tem is operating correctly, the
surrounding conditions as rec-
ognized by the driver and
detected by the system may dif-
fer. It is necessary for the driver
to pay attention, assess risks,
and ensure safety. Over-reli-
ance on this system to drive the
vehicle safely may lead to an
accident resulting in death or
serious injury.
●Proactive driving assist is not a
system which allows for inatten-
tive driving and is not a system
which assists in poor visibility
conditions. The driver is solely
responsible for paying attention
to their surroundings and driving
safely.

*: If equipped
When the front camera detects a sign or information
of a sign is available from the
navigation system, the sign
will be displayed on the dis-
p l a y.
 Multiple signs can be dis-
played.
Depending on the specifications of
the vehicle, the number of dis-
played signs may be limited.
■Operating conditions of sign
display
Signs will be displayed when the fol-
lowing conditions are met:
●The system has detected a sign
In the following si tuations, a dis-
played sign may stop being dis-
played:
●When a new sign has not been
detected for a certain distance
●When the system determines that
the road being driven on has
changed, such as after a left or
right turn
■Situations in which the display
function may not operate prop-
erly
In the following situ ations, the RSA
system may not operate properly
and may not detect signs or may
display the incorrect sign. However,
this does not indicate a malfunction.
●When a sign is dirty, faded, tilted
or bent
●When the contrast of an electronic
sign is low
●When all or part of a sign is hidden
by a tree, utility pole, etc.
●When a sign is d etected by the
front camera for a short amount of
time
●When the driving state (turning,
changing lanes, etc.) is judged
incorrectly
RSA (Road Sign
Assist)*
The RSA system detects
specific road signs using
the front camera and/or nav-
igation system (when speed
limit information is avail-
able) and warns the driver
via displays and buzzers.
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.
●Do not rely solely upon the
RSA. The RSA assists the
driver by providing road sign
information, but it is not a
replacement for the driver’s own
vision and awareness. Driving
safely is solely the responsibility
of the driver. Pay careful atten-
tion to the surrounding condi-
tions in order to ensure safe
driving.
■Situations in which the RSA
should not be used
●When it is necessary to disable
the system: P. 1 8 4

WARNING
●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.
●Even if the system is operating
correctly, the condition of a pre-
ceding vehicle as recognized by
the driver and detected by the
system may differ. Therefore, it
is necessary for the driver to
pay attention, assess risks, and
ensure safety. Over-reliance on
this system to drive the vehicle
safely may lead to an accident
resulting in death or serious
injury.
■Precautions for the driving
assist systems
Observe the following precau-
tions, as there are limitations to
the assistance provided by the
system. Over-reliance on this sys-
tem may lead to an accident
resulting in death or serious injury.
●Details of support provided for
the driver’s vision
The dynamic radar cruise control
is only intended to help the driver
in determining the distance
between the driver’s own vehicle
and a designated preceding vehi-
cle. It is not a system which allows
for careless or inattentive driving,
and is not a system which assists
in poor visibilit y conditions.
The driver must pay attention to
their surroundings, even when the
vehicle stops.
●Details of support provided for
the driver’s judgement
The dynamic radar cruise control
determines whether the distance
between the driver’s own vehicle
and a designated preceding vehi-
cle is within a set range. It is not
capable of making any other type
of judgement. Th erefore, it is
absolutely necessary for the
driver to remain vigilant and to
determine whether or not there is
a possibility of danger.
●Details of suppor t provided for
the driver’s operation
The dynamic radar cruise control
does not include functions which
will prevent or avoid collisions
with vehicles ahead of your vehi-
cle. Therefore, if there is ever any
possibility of danger, the driver
must take immediate and direct
control of the vehicle and act
appropriately in order to ensure
safety.
■Situations in which the
dynamic radar cruise control
should not be used
Do not use the d ynamic radar
cruise control in the following situ-
ations. As the system will not be
able to provide appropriate con-
trol, using it may lead to an acci-
dent resulting in death or serious
injury.
●Roads where there are pedes-
trians, cyclists, etc.
●When driving on a highway or
expressway entrance or exit
●When the approach warning
sounds frequently
●Situations in which the sensors
may not operate properly:
P.188
●Situations in which the lane may
not be detected:
P.189

■Accelerating after setting the
vehicle speed
As with normal dri ving, acceleration
can be performed by depressing the
accelerator pedal. After accelerat-
ing, the vehicle will return to the set
vehicle speed. However, while in
vehicle-to-vehicle distance control
mode, the vehicle speed may
decrease to below the set vehicle
speed in order to maintain the dis-
tance from the preceding vehicle.
■When the vehicle is stopped by
system control during follow-up
cruising
●When the “+RES” switch is
pressed while the vehicle is
stopped by system control, if the
preceding vehicle starts off within
approximately 3 seconds, fol-
low-up cruising will resume.
●If the preceding vehicle starts off
within approximately 3 seconds of
the vehicle being stopped by sys-
tem control, follo w-up cruising will
resume.
■Automatic cancellation of vehi-
cle-to-vehicle d istance control
mode
In the following situations, vehi-
cle-to-vehicle dista nce control mode
will be canceled automatically:
●When the brake control or output
restriction control of a driving sup-
port system operates
(For example: Pre-Collision Sys-
tem, drive-start control)
●When the parking brake has been
operated
●When the vehicle is stopped by
system control on a steep incline
●When any of the following are
detected while the vehicle is
stopped by system control:
• The driver’s seat belt is unfas- tened
• The driver’s door is opened
• Approximately 3 minutes have elapsed since the vehicle was
stopped The parking brake
may be actived
automatically.

sor may not detect correctly
In the following situations, depend-
ing on the conditions, if the system
cannot provide sufficient decelera-
tion or acceleration is necessary,
operate the brake pedal or accelera-
tor pedal.
As the sensor may not be able to
correctly detect th ese types of vehi-
cles, the approach warning
(  P.226) may not operate.
●When a vehicle cuts in front of
your vehicle or changes lanes
away from your vehicle extremely
slowly or quickly
●When changing lanes
●When a preceding vehicle is driv-
ing at a low speed
●When a vehicle is stopped in the
same lane as the vehicle
●When a motorcycle is traveling in
the same lane as the vehicle
■Conditions under which the
system may not operate cor-
rectly
In the following situations, operate
the brake pedal (or accelerator
pedal, depending on the situation)
as necessary.
As the sensor may not be able to
correctly detect a vehicle, the sys-
tem may not operate properly.
●When a preceding vehicle brakes
suddenly
●When changing lanes at low
speeds, such as in a traffic jam

2324-5. Using the driving support systems
the brake lights may illuminate,
depending on the road conditions,
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, the emergency flashers
(hazard lights) will flash to warn
other drivers of the emergency.

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.
