Lane centering function

■
This function is linked with radar cruise
control and provides the required
assistance by operating the steering
wheel to keep the vehicle in its current
lane.
When radar cruise control is not oper-
ating, the lane centering function does
not operate.
In situations where the white (yellow)
lane lines are difficult to see or are not
visible, such as when in a traffic jam,
this function will operate to help follow
a preceding vehicle by monitoring the
position of the preceding vehicle.
If the system detects that the steering
wheel has not been operated for a
fixed amount of time or the steering
wheel is not being firmly gripped, a
warning is displayed on the multi-infor-
mation display and the warning buzzer
sounds. Make sure to grip the steering
LS500h_OM_OM50F42U_(U)
wheel firmly.
