Updating the latest fuel consumption data
Resetting the history data
The average fuel consumption history is divided by color into past
averages and the average fuel consumption since the last updated.
Use the displayed average fuel consumption as a reference.
The image is an example only, and may vary slightly from actual
conditions.
■Updating the history data
Update the latest fuel consumption by selecting “Update” to measure the cur-
rent fuel consumption again.
■Resetting the data
The fuel consumption data can be deleted by selecting “Clear”.
■Cruising range
Displays the estimated maximum distance that can be driven with the quan-
tity of fuel remaining.
This distance is computed based on your average fuel consumption. As a
result, the actual distance that can be driven may differ from that displayed.
■Home screen
The average fuel consumption and distance to empty can be displayed on the
home screen of the navigation or multimedia system screen.
For details of the home screen, refer to the “Navigation and multimedia sys-

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
■ 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.

3244-5. Using the driving support systems
PRIUS_OM_OM47F32E_(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 main display or multi-information display.
●When the driving assist system
information is selected in multi-
information display, a maximum
of 2 signs can be displayed on
the multi-information display.
(P. 127)
●When a tab other than the driv-
ing assist system information is
selected, the following types of
road signs will be displayed on
the main display. (P. 117)

tion sign (Motorway,
Expressway, Urban area,
Residential area)

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 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 notification function
may not operate properly.
■Setting procedure
P. 153
■Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situations.
●No sign has been 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
