2164-5. Using the driving support systems
■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.

*: 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
■Situations in which the sys-
tem may not operate properly
●Situations in wh ich the sensors
may not operate properly:

2184-5. Using the driving support systems
●When a sign is immediately after a
freeway junction or in an adjacent
lane just before merging
●When stickers are attached to the
rear of a preceding vehicle
●When a sign similar to a system
compatible sign is detected as a
system compatible sign
●When a speed limit sign for a
frontage road is within detection
range of the front camera
●When driving around a round-
about
●When a sign intended for trucks,
etc. is detected
●When the navigation system map
data is out of date
●When the navigation system can-
not be used
In this case, the speed limit signs
displayed on the multi-information
display and navigat ion system dis-
play may differ.
In the following situations, the
RSA system will output a warn-
ing to notify the driver.
 If the vehicle speed exceeds
the speed warning threshold
of the speed limit sign dis-
played on the display, the sign
display will be emphasized
and a buzzer will sound.
 When the RSA system
detects a do not enter sign
and determines that the vehi-
cle has entered a no-entry
area, the do not enter sign
displayed on the display will
flash and a buzzer will sound.
■Operating conditions of the
notification functions
●Excess speed notification function
This function will operate when the
following condition is met:
• A speed limit road sign is recog- nized by the system.
●No entry notification function
This function will operate when all of
the following conditions are met:
• More than one no entry road signs are recognized by the system
simultaneously.
• The vehicle is passing between no entry road signs recognized by the
system.

Dynamic radar cruise
control
This dynamic radar cruise
control detects the pres-
ence of vehicles ahead,
determines the current vehi-
cle-to-vehicle distance, and
operates to maintain a suit-
able distance from the vehi-
cle ahead. The desired
vehicle-to-vehicle distance
can be set by operating the
vehicle-to-vehicle distance
switch.
Use the dynamic radar
cruise control only on high-
ways and expressways.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Do
not overly rely on this system,
and pay careful attention to the
surrounding conditions in order
to ensure safe driving.
●The dynamic radar cruise con-
trol provides driving assistance
to reduce the driver’s burden.
However, there are limitations to
the assistance provided.
Read the following items carefully.
Do not overly rely on this system
and always drive carefully.
Conditions under which the sys-
tem may not opera te correctly:

2204-5. Using the driving support systems
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.

■Preceding vehicles that the sen-
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

2264-5. Using the driving support systems
In situations where the vehicle
approaches a preceding vehicle
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.

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.
