In the following situations, the RSA system will notify the driver.
● When the vehicle speed exceeds the speed notification threshold of
the speed limit sign displayed, the sign display will be emphas ized
and a buzzer will sound.
● When the RSA system recognizes a no-entry sign and detects that
the vehicle has entered a no-entry area based on the map inform a-
tion of the navigation system, 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 overtaking
sign is displayed on the multi-information display, the display ed sign
will flash and a buzzer will sound.
Depending on the situation, traffic environment (traffic direct ion,
speed unit) may be detected incorrectly and a notification func tion
may not operate properly.
■ Setting procedure
Press “ ” or “” of meter control switches and select . (P. 170)
Press “ ” or “” of meter control switches and select , and press .
■ Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situa tions.

■ 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 do es not indicate a
malfunction.
● 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 inclement weather such as heavy rain, fog, snow or sand storms.
● Light from an oncoming vehicle, the sun, etc., enters the front camera.
● The sign is dirty, faded, tilted or bent.
● The contrast of electronic sign is low.
● All or part of the sign is hidden by the leaves of a tree, a pole, etc.
● The sign is only visible to the front camera for a short amount of time.
● The driving scene (turning, lane change, etc.) is judged incorrectly.
● If a sign not appropriate for the currently traveled lane, but the 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.
● Side road speed signs may be detected and displayed (if positioned in sight
of the front camera) 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 front camera) while traveling on a round about.
● The front of the vehicle is raised or lowered due to the carried load
● The surrounding brightness is not sufficient or changes suddenly.
● When a sign intended for trucks, etc. is recognized.
● The vehicle is driven in a country with a different direction of traffic.
● The navigation system map data is outdated. (vehicles with navigation sys-
tem)
● The navigation system is not operating. (vehicles with navigation system)
● The speed information displayed on the meter and on the navigation system
(if equipped) may be different due to the navigation system usi ng map data.

■ Speed limit sign display
If the power switch was last turned off while a speed limit sig n was displayed
on the multi-information display, the same sign displays again when the
power switch is turned to ON mode.
■ If “RSA Malfunction Visit Your Dealer” is shown
The system may be malfunctioning. Have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer.
■ Customization
Some functions can be customized. (Customizable features: P. 789)

Dynamic radar cruise controlwith full-speed
range
In vehicle-to-vehicle distance control mode, the vehicle automa tically
accelerates, decelerates and stops to match the speed changes o f the
preceding vehicle even if the accelerator pedal is not depresse d. In
constant speed control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control with full-speed range on f ree-
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 with full-speed range provides driving
assistance to reduce the driver’s burden. However, there are li mitations to
the assistance provided.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahe ad:
P. 425
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 426
● Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
● Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condi tion
observed by the driver. Therefore, the driver must always remai n alert,
assess the danger of each situation and drive safely. Relying s olely on this
system or assuming the system ensures safety while driving can lead to
an accident, resulting in death or serious injury.
● Switch the dynamic radar cruise control with full-speed range setting to off,
using the “ON-OFF” button 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 system.
Failure to do so may cause an accident resulting in death or se rious 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 following distance between t he 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 contro l 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 absolut ely neces-
sary 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 vehicles 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 approp riately in
order to ensure the safety of all involved.

WARNING
■Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control with full-speed range i n any of the
following situations.
Doing so may result in inappropriate speed control and could ca use 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 stee p 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 or front
camera
● 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 to detect the presence of vehicles up to
approximately 100 m (328 ft.) ahead, determines the current veh icle-
to-vehicle following distance, and operates to maintain a suita ble fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehicle
distance can also be set by operating the vehicle-to-vehicle di stance
switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
