Cleaning the sensors


Park assist sensors
The sensors must be cleaned regularly to ensure that they work properly. Clean them with water and a suitable car washing detergent.
Ice and snow covering the sensors may cause incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false warning
signals from the park assist system.
