Possible cause
The tire pressure monitoring system* is
using the current pressure values as the
basis for monitoring.
The tire inflation pressure is being
checked.
The tire pressure monitoring system* is
unable to monitor the tire inflation pres-
sure due to
the presence of several wheel sensors
in the vehicle.
excessive wheel sensor tempera-
tures.
a nearby radio interference source.
unrecognized wheel sensors mount-
ed.
The pressure is too low in one or more
tires.
Possible solution
Remove any extra wheel sensors from
the vehicle.
As soon as the causes of the malfunction
have been removed, the tire pressure
monitoring system* automatically be-
comes active again.
Check and correct tire inflation pres-
sure as required ( page 318).
