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 (For details,
See “SETTING THE LEXUS PARK-
ING ASSIST-SENSOR MODE” on

while checking the safety of the sur-
rounding area both directly and using
the mirrors. After the operation, turn
the switch on.

far, and the system cannot function.

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.
