Depending on the vehicle condition and road conditions, the warning may not
operate. Also, if the system determines
that the vehicle is driving around a curve, warnings will occur earlier than
during straight-lane driving.
●When the system determines that the
driver is driving without holding the
steering wheel while the steering wheel assist of the steering assist
function is operating.
If the driver continues to keep their
hands off of the steering wheel and the
steering wheel assist is operating, the buzzer sounds and the driver is warned.
Each time the buzzer sounds, the con-
tinuing time of the buzzer becomes

to a malfunction in a sensor other than
the front camera. Turn the LTA system off, wait for a little while, and then turn
the LTA system back on.
