4-5. Using the driving support systems
RSA (Road Sign Assist)
*
: If equipped
The RSA system detects specific
road signs using the front camera
and/or navigation system (when
speed limit information is available)
and warns the driver via displays
and buzzers.
WARNING
For safe use
■
Driving safely is solely the responsibil-
●
ity of the driver. Pay careful attention to
the surrounding conditions in order to
ensure safe driving.
●
Do not rely solely upon the RSA. The
RSA assists the driver by providing
road sign information, but it is not a
replacement for the driver's own vision
and awareness. Driving safely is solely
the responsibility of the driver. Pay
careful attention to the surrounding
conditions in order to ensure safe driv-
ing.
■
Situations in which the RSA should
not be used
●
When it is necessary to disable the sys-
tem: P.229
Situations in which the system may
■
not operate properly
Situations in which the sensors may not
●
operate properly: P.234
Display Function
When the front camera detects a
sign or information of a sign is avail-
able from the navigation system, the
sign will be displayed on the display.
Multiple signs can be displayed.
Depending on the specifications of the
*
vehicle, the number of displayed signs may
be limited.
Operating conditions of sign display
■
Signs will be displayed when the following
conditions are met:
●
The system has detected a sign
In the following situations, a displayed sign
may stop being displayed:
●
When a new sign has not been detected
for a certain distance
When the system determines that the
●
road being driven on has changed, such
as after a left or right turn
■
Situations in which the display function
may not operate properly
In the following situations, the RSA system
may not operate properly and may not
detect signs or may display the incorrect
sign. However, this does not indicate a mal-
function.
When a sign is dirty, faded, tilted or bent
●
●
When the contrast of an electronic sign is
low
When all or part of a sign is hidden by a
●
tree, utility pole, etc.
●
When a sign is detected by the front cam-
era for a short amount of time
●
When the driving state (turning, chang-
ing lanes, etc.) is judged incorrectly
When a sign is immediately after a free-
●
way junction or in an adjacent lane just
before merging
●
When stickers are attached to the rear of
a preceding vehicle
When a sign similar to a system compati-
●
ble sign is detected as a system compati-
ble sign
●
When a speed limit sign for a frontage
road is within detection range of the front
camera
●
When driving around a roundabout
When a sign intended for trucks, etc. is
●
detected
