If the Lexus parking assist-sensor
detects an object while you attempt to
park in a parking space on the left, the
black and yellow vertical pole could be
obscured by the Lexus parking assist
display. In this event, turn the Lexus
parking assist-sensor off (P.311), and
operate the vehicle while checking the
safety of the surrounding area both
directly and using the mirrors. After the
operation, turn the switch on.
The steering wheel has been turned too
far, and the system cannot function.
Return the steering wheel to its original
position.
If the message is displayed before the
outline is positioned over the desired
parking space, it is likely that the vehi-
cle is too far away from the shoulder.
Check that there is a gap of approxi-
mately 3 ft. (1 m) between your vehicle
and the parked vehicle.
