RSA (Road Sign
*
Assist)

: If equipped
The RSA system detects
specific road signs using
the front camera and/or nav-
igation system (when speed
limit information is avail-
able) and warns the driver
via displays and buzzers.
WARNING
■ For safe use
Driving safely is solely the
●
responsibility of the driver. Pay
careful attention to the sur-
rounding 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 atten-
tion to the surrounding condi-
tions in order to ensure safe
driving.
