Driving
*: 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:
 P. 1 8 8
Display Function

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.
 The following types of road
signs can be displayed.
However, non-standard or recently
introduced traffic signs may not be
displayed.

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:

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

Driving
Constant speed cruising:
When there are no vehicles ahead
The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle
speed display will blin k and a buzzer will sound.
Deceleration and follow-up cruising
When a preceding vehicle driving slower than the set vehicle
speed is detected
When a vehicle is detected driving ahead of your vehicle, the v ehicle auto-
matically decelerates and if a greater reduction in vehicle spe ed is neces-
sary, the brakes are applied (the stop lights will come on at t his time). The
vehicle is controlled to maintai n the vehicle-to-vehicle distance set by the
driver, in accordance with changes in the speed of the precedin g vehicle. If
vehicle deceleration is not sufficient and the vehicle approaches the vehicle
ahead, the approach wa rning will sound.
Acceleration
When there are no longer any preceding vehicles driving slower
than the set vehicle speed
The vehicle accelerates until th e set vehicle speed is reached and then
resumes constant speed cruising.
Starting off:
If a preceding vehicle stops, the vehicle will also stop (contr olled
stop). After the preceding vehicle starts off, pressing the “RES”
switch or depressing the accelerator pedal will resume follow-u p
cruising (start off operation). If a start off operation is not per-
