Possible cause/consequence
The TPMS (USA only) or Advanced TPMS
(Canada only) is unable to monitor the tire
pressure due to a nearby radio interfer-
ence source or insufficient power supply.
Vehicles with Advanced TPMS (Canada
only):
The tire pressure is too low in one or more
tires.
or
The tire pressures of the individual tires
differ from each other significantly.
The tire pressure values are shown in the
multifunction display.
Vehicles with Advanced TPMS (Canada
only):
One or more tires are deflating.
The respective tire is indicated in the mul-
tifunction display.
Possible solution
As soon as the causes of the malfunction have
been removed, the TPMS or Advanced TPMS
automatically becomes active again after a few
minutes driving.
