The tire inflation pressure monitor does not
indicate a warning for wrongly selected inflation
pressures. Always adjust tire inflation pressure
according to the label affixed on the fuel filler flap.
See page 351 for tire inflation pressure.The tire inflation pressure monitor is not able to
issue a warning due to a sudden loss of pressure
(e.g. tire puncture caused by a foreign object). In
this case bring vehicle to a halt by carefully
applying the service brakes and avoiding abrupt
steering maneuvers.
