system will notify the driver.
 When the vehicle speed exceeds
the speed notific ation threshold
of the speed limit sign displayed,
the sign display will be empha -
sized and a buzzer will sound.
 When the RSA system recog-
nizes a no-entry sign and detects
that the vehicle has entered a
no-entry area based on the map
information of the navigation sys -
tem, the no-entry sign flashes
and a buzzer will sound. (For
vehicles with navigation system)
 If it is detected that your vehicle
is overtaking when a no overtak -
ing sign is displayed on the multi-
information display, the dis -
played sign will flash and a steer -
ing wheel will vibrate.
Depending on the situation, traffic
environment (traffic direction,
speed unit) may be detected incor -
rectly and a notification function
may not operate properly.
■Setting procedure

■Automatic turn-off of RSA sign dis-
play
One or more signs automatically turn off
in the following situations.
●No sign has been recognized for a
certain distance.
●The road changes due to a left or right
turn, etc.
■Conditions in which the function
may not operate or detect correctly
In the following situations, RSA does not
operate normally and may not recognize
signs, display the i ncorrect sign, etc.
However, this does not indicate a mal - function.
●The front camera is misaligned due to a strong impact being applied to the
sensor, etc.
●Dirt, snow, stickers, etc. are on the
windshield near the front camera.

In vehicle-to-vehicle distance
control mode, the vehicle auto -
matically accelerates, deceler -
ates and stops to match the
speed changes of the preced -
ing vehicle even if the acceler -
ator pedal is not depressed. In
constant speed control mode,
the vehicle runs at a fixed
speed.
Use the dynamic radar cruise
control with full-speed range
on freeways and highways.

WARNING
■Before using dynamic radar
cruise control with full-speed
range
●Driving safely is the sole responsi -
bility of the driver. Do not rely solely
on the system, and drive safely by always paying careful attention to
your surroundings.
●The dynamic radar cruise control
with full-speed range provides driv -
ing assistance to reduce the driver’s burden. However, there are
limitations to the assistance pro -
vided.
Read the following conditions care -
fully. Do not overly rely on this system
and always drive carefully.

• Conditions under which the vehicle- to-vehicle distance control mode
may not function correctly: →P.387
●Set the speed appropriately
depending on the speed limit, traffic
flow, road conditions, weather con - ditions, etc. The driver is responsi -
ble for checking the set speed.
●Even when the system is function -
ing normally, the condition of the
preceding vehicle as detected by the system may differ from the con -
dition observed by the driver.
Therefore, the dri ver must always remain alert, assess the danger of
each situation and drive safely.
Relying solely on this system or assuming the system ensures
safety while driving can lead to an
accident, resulti ng in death or seri- ous injury.
●Switch the dynamic radar cruise control with full-speed range setting
to off, using the cruise control main
switch when not in use.

WARNING
■Cautions regarding the driving
assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the syst em. Failure to do
so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure fol -
lowing distance
The dynamic radar cruise control with
full-speed range is only intended to
help the driver in determining the fol -
lowing distance bet ween the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows carele ss or inattentive
driving, and it is not a system that can
assist the driver in low-visibility condi-
tions.
It is still necessary for driver to pay
close attention to the vehicle’s sur -
roundings.
●Assisting the driver to judge proper
following distance
The dynamic radar cruise control with
full-speed range determines whether
the following dist ance between the
driver’s own vehicle and a designated
vehicle traveling ahead is within a set
range. It is not capable of making any
other type of judgemen t. Therefore, it
is absolutely necessary for the driver
to remain vigilant and to determine
whether or not there is a possibility of
danger in any given situation.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with
full-speed range does not include
functions which will prevent or avoid
collisions with vehi cles ahead of your
vehicle. 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 the safety of all
involved.
■Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise con-
trol with full-speed range in any of the
following situations. Doing so may result in inappropriate speed control
and could cause an accident resulting
in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●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
Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and high - ways
●When weather conditions are bad
enough that they may prevent the sensors from detecting correctly
(fog, snow, sandstorm, heavy rain,
etc.)

Driving
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, det ermines the current vehicle-to-vehicle fol-
lowing distance, and operates to m aintain a suitable following distance from
the vehicle ahead. The desired v ehicle-to-vehicle distance can also be set
by operating the vehicle-to -vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.

3805-5. Using the driving support systems
When a vehicle is de tected running ahead of you, the system automatically deceler-
ates your vehicle. When a great er reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this time). The system will
respond to changes in the speed of the vehicle ahead in order to maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also sto p (vehicle is stopped
by system control). After the veh icle ahead starts off, pressing the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume follow-up cruising.
If the start-off operation is not performed, system control continues to keep your
vehicle stopped.
When the turn signal lever is operated and your vehicle moves t o an overtaking lane
while driving at 50 mph (80 km/h) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identificat ion of what is an overtaking lane may be determined solely
based on the location of the ste ering wheel in the vehicle (left side driver position
versus right side driv er position.) If the vehicle is driven to a region where the over-
taking lane is on a different sid e from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e opposite direction to
the overtaking lane (e.g., if th e driver normally operates the vehicle in a region
where the overtaking lane is to t he right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration
When there are no longer any preceding vehicles driving slower than the
set speed
The system accelerates until the set speed is reached. The system then returns to
constant speed cruising.

switch to activate the cruise con -
trol.
Dynamic radar cruise control indicator
