We experienced a LKA system turn off on a recent trip. How does one turn it on again?
If it went off due to taking your hands off, it should go right back on again when you take control. There is a button on the lower left of the dash to turn it off and on. Check your setup:
The driver can change LKAS to Lane Departure Warning System (LDWS) or
the LKAS mode between Standard LKA and Active LKA from the User
Settings Mode on the LCD display.
Lane Departure Warning
LDWS alerts the driver with a visual
and acoustic warning when the system
detects the vehicle leaving the
lane. In this mode, the steering
wheel
will not be controlled. When the vehicle’s
front
wheel contacts the inside
edge of lane line, LKAS issues the
lane departure warning.
Standard LKA
The Standard LKA mode guides the
driver to help keep the vehicle within
the lanes. It rarely controls the steering
wheel, when the vehicle drives
well inside the lanes. However, it
starts to control the steering
wheel,
when the vehicle is about to deviate
out of the lanes.
Active LKA
The Active LKA mode provides more
frequent steering
wheel control in
comparison with the Standard LKA
mode. Active LKA can reduce the driver’s
fatigue to assist the steering for
maintaining the vehicle in the middle
of the lane.
