RSA (Road Sign Assist)
The RSA system recognizes spe-
cific road signs using the front
camera and/or navigation system
(when data is available) to provide
information to the driver via the
display.
If the system judges that the vehicle is being driven over the speed
limit, performing prohibited actions, etc., in relation to the recognized
road signs, it alerts the driver using a warning display and warning
buzzer.
: If equipped
Summary of function
WARNING
■ Before using the RSA
Do not rely solely upon the RSA system. RSA is a system which supports
the driver by providing information, but it is not a replacement for a driver’s
own vision and awareness. Drive safely by always paying careful attention
to the traffic rules.

3624-5. Using the driving support systems
HILUX_OM_OM0K321E_(EE)
When the front camera recognizes a sign, and/or information of a sign
is available from the navigation system, the sign will be displayed on
the multi-information display.
● When the driving support sys-
tem information is selected, a
maximum of 3 signs can be dis-
played. ( P. 151)
● When a tab other than the driv-
ing support system information
is selected, only a recognized
speed limit sign, a no-entry
sign* (when notification is nec-
essary), expressway sign, high-
way sign or Residential area
sign will be displayed.
( P. 151)
A no overtaking sign and a speed limit sign with supplemental mark are
not displayed. However, if signs other than speed limit signs are recog-
nized, they will be displayed in an overlapping stack under the current
speed limit sign.

In the following situations, the RSA system will alert the driver.
● When the vehicle speed exceeds the speed warning threshold of
the speed limit sign displayed, the sign display will be emphasized
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 informa-
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 displayed sign
will flash and a buzzer will sound.
Depending on the situation, traffic environment (traffic direction,
speed unit) may be detected incorrectly and a warning indication may
not operate properly.
■ Setting procedure
Setting for “RSA” in of the multi-information display is set to “On”
( P. 151)
■ 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 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, 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 front camera for a short amount of time.
● The driving scene (turning, lane change, etc.) is judged incorrectly.
Warning indication

3664-5. Using the driving support systems
HILUX_OM_OM0K321E_(EE)
● 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.
● 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 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 old.
● The navigation system is not operating.
● The speed information displayed on the meter and that displayed on the
navigation system may be different due to the navigation system using map
data.
■ Speed limit sign display
If the engine switch was last turned to the “LOCK” position (vehicles without
smart entry & start system) or off (vehicles with smart entry & start system)
while a speed limit sign was displayed on the multi-information display, the
same sign displays again when the engine switch is turned to the “ON” posi-
tion (vehicles without smart entry & start system) or IGNITION ON mode
(vehicles with smart entry & start system).
■ 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 reliable repairer.
■ Customization
Some functions can be customized.

Dynamic radar cruise control
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates and decelerates to match the speed changes of the pre-
ceding vehicle even if the accelerator pedal is not depressed. In con-
stant speed control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control on freeways and highways.
● Vehicle-to-vehicle distance control mode (P. 371)

WARNING
■Before using dynamic radar cruise control
● 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 provides driving assistance to reduce the
driver’s burden. However, there are limitations 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 ahead:
 P. 381
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 382
● 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 condition
observed by the driver. Therefore, t he driver 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, resulting in death or serious injury.
● Switch the dynamic radar cruise control 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 serious injury.
● Assisting the driver to measure following distance
The dynamic radar cruise control is only intended to help the driver in
determining the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead. It is not a mechanism that allows care-
less 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 sur-
roundings.
● Assisting the driver to judge proper following distance
The dynamic radar cruise control det ermines whether the following dis-
tance 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 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 does not include functions which will pre-
vent 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 appropriately in order to ensure the
safety of all involved.

WARNING
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control 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 or front
camera
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● When your vehicle is towing a trailer (with towing hitch) or during emer-
gency towing
● When an approach warning buzzer is heard often
