■Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situations.
● A new sign is not 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 rec-
ognize signs, display the incorrect sign, etc. However, this does not indicate a
malfunction.
● The camera sensor is misaligned due to a strong impact being applied to
the sensor, etc.
● Dirt, snow, stickers, etc., are on the windshield near the camera sensor.
● In inclement weather such as heavy rain, fog, snow or sand storms
● Light from an oncoming vehicle, the sun, etc., enters the camera sensor.
● The sign is dirty, faded, tilted or bent, and if an electronic sign, the contrast
is poor.
● All or part of the sign is hidden by the leaves of a tree, a pole, etc.
● The sign is only visible to the camera sensor for a short amount of time.
● The driving scene (turning, lane change, etc.) is judged incorrectly.
● Even if it is a sign not appropriate for the currently traveled lane, such a sign
exists directly after a freeway branches, or in an adjacent lane just before
merging.
● Stickers are attached to the rear of the preceding vehicle.
● A sign resembling a system compatible sign is recognized.
● The vehicle is driven in a country with a different direction of traffic.
● Side road speed signs may be detected and displayed (if positioned in sight
of the camera sensor) while the vehicle is traveling on the main road.
● Roundabout exit road speed signs may be detected and displayed (if posi-
tioned in sight of the camera sensor) while traveling on a roundabout.
● The speed information displayed on the meter and that displayed on the
navigation system (if equipped) may be different due to the navigation sys-
tem using map data.

■ When driving vehicle in country with different speed unit
Since RSA recognizes signs based on the set unit of the meter, it is neces-
sary to change the set unit of the meter. Adjust the set unit of the meter to the
speed unit of signs in the current location. ( P. 679)
■ Turning the system on/off
■ Speed limit sign display
If the power switch was last turned off while a speed limit sign was displayed
on the multi-information display, the same sign displays again when the
power switch is turned ON mode.
■ Customization
Setting (e.g. speeding warning threshold) can be changed.

Dynamic radar cruise controlwith full-speed
range
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates, decelerates and stops to match the speed changes of the
preceding vehicle even if the accelerator 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 free-
ways and highways.

WARNING
■Before using dynamic radar cruise control with full-speed range
Driving safely is the sole responsibility of the driver. Do not rely solely on the
system, and drive safely by always paying careful attention to your sur-
roundings.
The dynamic radar cruise control wi th full-speed range provides driving
assistance to reduce the driver’s burden. However, there are limitations to
the assistance provided.
Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, t he driver must always remain alert,
assess the danger of each situation and drive safely. Relying on this system
or assuming the system ensures safety while driving can lead to an acci-
dent, resulting in death or serious injury.
■ Cautions regarding the driving assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident resulting in death or serious injury.
● Assisting the driver to measure following distance
The dynamic radar cruise control with full-speed range is only intended to
help the driver in determining the fo llowing distance between the driver’s
own vehicle and a designated vehicle traveling ahead. It is not a mecha-
nism that allows careless or inattentive driving, and it is not a system that
can assist the driver in low-visibility conditions. It is still necessary for
driver to pay close attention to the vehicle’s surroundings.
● Assisting the driver to judge proper following distance
The dynamic radar cruise control with full-speed range determines
whether the following distance 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 judgement. Therefore, it is absolutely neces-
sary for the driver to remain vigila nt 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 has limited capabil-
ity to prevent or avoid a collision wi th a vehicle traveling ahead. Therefore,
if there is ever any danger, the driver must take immediate and direct con-
trol of the vehicle and act appropriately in order to ensure the safety of all
involved.

WARNING
■To avoid inadvertent dynamic radar cruise control with full-speed
range activation
Switch the dynamic radar cruise control with full-speed range off using the
“ON-OFF” button when not in use.
■ Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent 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 highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When there is rain, snow, etc., on the front surface of the radar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● When your vehicle is towing a trailer or during emergency towing
● When an approach warning buzzer is heard often

This mode employs a radar sensor to detect the presence of vehicles
up to approximately 100 m (328 ft.) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehi-
cle-to-vehicle distance can also be set by operating the vehicle-to-vehicle
distance switch.

Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system 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 vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal will resume fol-
low-up cruising.
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.

Press the “ON-OFF” button to
activate the cruise control.
Radar cruise control indicator will
come on and a message will be
displayed on the multi-information
display.
Press the button again to deacti-
vate the cruise control.
If the “ON-OFF” button is pressed
and held for 1.5 seconds or more,
the system turns on in constant
speed control mode. ( P. 317)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed
(above approximately 50 km/h
[30 mph]) and push the lever
down to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the lever is released becomes the
set speed.
If the lever is operated while the
vehicle speed is below approxi-
mately 50 km/h (30 mph) and a
preceding vehicle is present, the
set speed will be adjusted to
approximately 50 km/h (30 mph).
