CURRENTLY
UNAVAILABLE
The tire inflation pressure monitor* is un-
able to monitor the tire pressure due to:
the presence of several wheen sen-
sors in the vehicle

Remove any extra wheel sensors from the
vehicle
As soon as the causes of the malfunction
have been removed, the tire pressure moni-
tor automatically becomes active again.
