## NHTSA's summary

DESCRIPTION Van Hool has been informed about a harmless phenomenon regarding the front entrance door when the air suspension raising system is activated. Investigation has shown that when the raising system is activated, air is pulled out of the front passenger compressedair circuit causing the quick release valve in that circuit to a momentary switch. This can be noticed by a short soft sound of escaping air. This service bulletin gives step\-by\-step instructions how to install an additional singlecheck valve to prevent this phenomenon from happening.
