4-5. Using the driving support systems
In the following situations, the RSA sys-
tem 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-information
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-infor-
mation display, the sign flashes.

When the RSA system recognizes a
no-entry sign and detects that the
vehicle has entered a no-entry area
based on the map information of the
navigation system, the no-entry sign
flashes.
Depending on the situation, traffic
environment (traffic direction, speed,
unit) may be detected incorrectly and a
warning display may not operate prop-
erly.
■
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 recognize
signs, display the incorrect sign, etc. How-
ever, this does not indicate a malfunction.
●
The camera sensor is misaligned due to a
strong impact being applied to the sen-
sor, etc.
●
Dirt, snow, stickers, etc. are on the wind-
shield 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.
●
The sign is only visible to the camera sen-
sor 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 positioned
in sight of the camera sensor) while
traveling on a roundabout.
■
When driving vehicle in country with dif-
ferent speed unit
Since RSA recognizes signs based on the
set unit of the meter, it is necessary 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. (
