RSA (Road Sign Assist)
RSA recognizes specific road signs using the front sensor and pro-
vides 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.

Summary of function

2964-5. Toyota Safety Sense
YARIS_HV_OM_Europe_OM52J66E
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.
Depending on the situation, the driving behavior (turning, lane change, etc.)
may be detected incorrectly and the automatic turn-off may not operate
properly.

■ 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. 608)
■ 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 to the “ON” position (vehicles without a smart entry &
start system) or ON mode (vehicles with a smart entry & start system).
■ When “Check RSA system.” is displayed on the multi-information dis-
play
The system may be malfunctioning. Have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer
immediately.
■ Customization
The settings for warning display, warning buzzer*, speeding warning thresh-
old, etc., can be changed. (Customizable feature: P. 608)
*: If a speed limit with supplemental mark is exceeded, the warning buzzer
does not operate.
Select on the settings display
( P. 125)
Press the enter/set switch on the meter
control switches.
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.

WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten t he vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.

WARNING
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
● Use snow tires on all, not just some wheels.
● Do not use tires of noticeably different wear level.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
● Do not use LDA (Lane Departure Alert) (if equipped).
