Parking sensor warning
A car with sensor waves, or a Park Assist Unavailable message.
GENERALLY OK TO PROCEED WITH CAUTION
Book it in when you can · Amber means get it checked
What it means
Parking sensors beep as you approach an obstacle. A warning means one or more sensors are unavailable — very often just dirt, snow or ice over a bumper sensor.
Can I drive?
Yes. Park using your mirrors, the backup camera, and a look around, as you would without sensors, until it clears.
Common causes
A dirty or covered bumper sensor, a knock that misaligned one, or a wiring fault. Cleaning the bumper often fixes it.
Warning-light symbols and meanings vary by vehicle — always check your owner’s manual. This is general guidance based on what the light indicates, not a physical inspection, and a light on its own never names a failed part.
