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

operate the vehicle while checking the
safety of the surrounding area both
directly and using the mirrors. After the
operation, turn the switch on.

mately 3 ft. (1 m) between your vehicle
and the parked vehicle.
