Lexus park assist system failure warning

The system self check is automatically performed when

the Lexus park assist system is turned on. At this time if

an error is detected, the master warning light comes on

accompanied by 5 beeps, the faulty sensor blinks and

either of the following messages appear in the

multi-information display.

D "Check Park Sonar"

D "Clean Park Sonar"

The sensors operate individually. When one sensor is

malfunctioning, you will notice sounding beeps and blinking

indicators to show that it is malfunctioning. If another sensor

detects an obstacle during this time, the approximate distance

to the obstacle will be shown by that sensor.

STARTING AND DRIVING

If the sensor is malfunctioning or a cable is broken, the

above message appears.

Although it is no problem to continue driving, have your vehicle

checked by your Lexus dealer as soon as possible.

If icicles, snowflakes or mud gets on the sensor or it is

frozen, the sensor may not be able to detect an obstacle.

In either case, the above message appears.

Remove the foreign matter or deice the sensor. If the message

does not appear after cleaning, the system is operating
