Fiat Abarth 500 2015 Owner's Manual page 288

286 STARTING AND OPERATING
• Installing some form of aftermarket window tinting
that affects radio wave signals.
• Snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
NOTE: Your vehicle may be equipped with a compact
spare wheel and tire assembly.
• The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not moni-
tor the tire pressure in the compact spare tire.
• If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition key cycle, a chime will
sound, the Tire Pressure Monitoring Telltale Light and
the Low inflation pressure left or right front / rear tire
message will still turn ON due to the low tire.
• However, after driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid and the "Service Tire Pressure
Monitoring System" message will be displayed.
• This occurs for each subsequent ignition key cycle, a
chime will sound and the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid and the "Service Tire Pressure
Monitoring System" message will be displayed.
