1. Messen:
Reifenluftdruck
Nicht nach Vorgabe → Korrigieren.
HINWEIS:
 Den Reifenluftdruck bei kaltem Reifen kon-
trollieren.
 Bei zu niedrigem Reifenluftdruck besteht die
Gefahr, dass der Reifen auf der Felge
rutscht.
 Ein schr äg stehender Ventilschaft deutet
darauf hin, dass der Reifen sich verschoben
hat.
 Falls der Ventilschaft schr äg steht, sitzt der
Reifen falsch auf. In diesem Fall die Reifen-
lage korrigieren.
