WARNING
■Before using the LDA system
●Do not overly rely on the LDA
system. The LDA system is not
a system which provides auto-
mated assistance in driving and
it is not a system which reduces
the amount of attention neces-
sary for safe driv ing. The driver
is solely responsible for paying
attention to their surroundings
and operating the steering
wheel as necessary to ensure
safety. Also, the driver is
responsible for taking adequate
breaks when fatigued, such as
when driving for a long time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident.
