Functions included in LTA system
Lane departure alert function
■
When the system determines that the
vehicle might depart from its lane or
*
course , a warning is displayed on the
multi-information display, and either a
warning buzzer will sound or the steer-
ing wheel will vibrate to alert the driver.
When the warning buzzer sounds or
the steering wheel vibrates, check the
area around your vehicle and carefully
operate the steering wheel to move the
vehicle back to the center of the lane.
When the system determines that the
vehicle might depart from its lane and
that the possibility of a collision with an
overtaking vehicle in the adjacent lane
is high, the lane departure alert will
operate even if the turn signals are
operating.
