The tire pressure losswarning system does notreplacethe needtoregularlycheckthe tire pres‐sure.
System limitations
The system may be impaired or may not functionparticularlyinthefollowing situations:
RIncorrectly set tire pressure
RSudden pressure loss caused,forexample,byaforeign object penetratingthe tire
RSteady pressure loss in several tires
The system has arestricted or delayed functionparticularly inthefollowing situations:
RPoor ground conditions, e.g. snow or gravel
RDriving withsnowchains
RWhen adopting averysporty drivingstylewith high cornering speeds or sudden accel‐eration
RDriving with a high load
