LDA (Lane Departure Alert)
When driving on roads with white (yellow) lines, this function alerts the
driver when the vehicle might depart from its lane.
The LDA system recognizes visi-
ble white (yellow) lines with the
camera sensor on the upper por-
tion of the front windshield.
◆Lane departure alert function
When the system determines
that the vehicle might depart
from its lane, a warning is dis-
played on the multi-information
display and the warning buzzer
sounds to alert the driver.
When the warning buzzer
sounds, check the surrounding
road situation and carefully
operate the steering wheel to
move the vehicle back to the
center of the lane.

RSA (Road Sign Assist)
RSA recognizes specific road
signs using the camera sensor
and provides information to the
driver via the multi-information
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*.
*: This setting needs to be customized.
: If equipped

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.
Inappropriate or negligent driving could lead to an unexpected accident.
Page 344 of 708
3444-5. Using the driving support systems
HILUX_OM_OM0K375E_(EE)
After the camera sensor recognizes a sign, it is displayed on the multi-
information display when the vehicle passes the sign.
● When the driving assist system
information is selected, a maxi-
mum of 3 signs can be dis-
played. ( P. 141)
● When other than the driving
assist system information is
selected, a speed limit sign, a
highway sign or an all canceled
sign can be displayed.
( P. 141)
A no overtaking sign and a
speed limit sign with supple-
mental mark are not displayed.
However, if signs other than
speed limit signs are recog-
nized, they are mentioned in a
stack under the current speed
limit sign.
Indication on the multi-information display
Page 346 of 708

3464-5. Using the driving support systems
HILUX_OM_OM0K375E_(EE)
*1: A speed limit sign with a value greater than 130 may not be recognized
and a wrong speed limit may be displayed.
*2: If the turn signal indicator is not operated when changing lanes, the mark
does not display.
In the following situations, the RSA system alerts the driver using a
warning display.
● When the vehicle speed exceeds the speed warning threshold
applied to the speed limit of the sign displayed on the multi-informa-
tion display, the sign color becomes inverted.
● If it is detected that your vehicle is overtaking when a no overtaking
sign is displayed on the multi-information display, the sign flashes.
Depending on the situation, traffic environment (traffic direction,
speed, unit) may be detected incorrectly and a warning display may
not operate properly.
■ 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.
All canceled
(All restrictions canceled. Returns to
default road regulation.)

Driving
HILUX_OM_OM0K375E_(EE)
● 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 multimedia 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. 684)
■ Turning the system on/off
Use the meter control switches to select while the vehicle is stopped and
press , and select and press . ( P. 141)
■ 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).
■ Customization
Setting (e.g. speeding warning threshold) can be changed.
(Customizable feature: P. 683)
