from its lane or course* in a short period of time. Turn the engine switch
to the “LOCK” position (vehicles without smart entry & start system) or off
(vehicles with smart entry & start system), and then turn it to the “ON”
position (vehicles without smart entry & start system) or IGNITION ON
mode (vehicles with smart entry & start system) again.
*: Boundary between asphalt and the side of the road, such as grass, soil, or
a curb

RSA (Road Sign Assist)
The RSA system recognizes spe-
cific road signs using the front
camera and/or navigation system
(when speed limit information 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., according to the recognized
road signs, it notifies the driver through a visual notification and notifi-
cation buzzer.
: If equipped
Summary of function
WARNING
Q 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.

2994-5. Using the driving support systems

Driving
HILUX_OM_OM0K513E_(EE)
In the following situations, the RSA system will notify the driver.
O When the vehicle speed exceeds the speed notification threshold of
the speed limit sign displayed, the sign display will be emphasized
and a buzzer will sound.
O 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)
O 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 notification function
may not operate properly.
Q Setting procedure
Setting for “RSA” in of the multi-information display is set to “On”
( P. 139)
Q Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situations.
O No sign has been recognized for a certain distance.
O The road changes due to a left or right turn, etc.
Q 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.
O The front camera is misaligned due to a strong impact being applied to the
sensor, etc.
O Dirt, snow, stickers, etc. are on the windshield near the front camera.
O In inclement weather such as heavy rain, fog, snow or sand storms.
O Light from an oncoming vehicle, the sun, etc. enters the front camera.
O The sign is dirty, faded, tilted or bent.
O The contrast of electronic sign is low.
O All or part of the sign is hidden by the leaves of a tree, a pole, etc.
O The sign is only visible to the front camera for a short amount of time.
O The driving scene (turning, lane change, etc.) is judged incorrectly.
Notification function

3004-5. Using the driving support systems
HILUX_OM_OM0K513E_(EE)
O 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.
O Stickers are attached to the rear of the preceding vehicle.
O A sign resembling a system compatible sign is recognized.
O 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.
O Roundabout exit road speed signs may be detected and displayed (if posi-
tioned in sight of the front camera) while traveling on a roundabout.
O The front of the vehicle is raised or lowered due to the carried load.
O The surrounding brightness is not sufficient or changes suddenly.
O When a sign intended for trucks, etc. is recognized.
O The vehicle is driven in a country with a different direction of traffic.

may be different due to the navigation system using map data.
Q 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).
Q 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.
Q Customization
Some functions can be customized. (Customizable features: P. 647)

WARNING
QBefore using dynamic radar cruise control
O 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.
O 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. 315
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 316
O 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.
O 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.
O Switch the dynamic radar cruise control setting to off, using the “ON-OFF”
button when not in use.
