WARNING
Before starting any servicing operation,
stop the engine and remove the key
from the ignition switch to operate the
steering lock, particularly when the wheels do
not touch the ground. If this is not possible
(for example if the key needs to be turned to
MAR-ON or the engine must be running),
remove the main fuse that protects the
electric power steering.
TYRE PRESSURE MONITORING
SYSTEM TPMS(Tyre Pressure Monitoring System)
(for versions/markets, where provided)
The car may be fitted with a tyre pressure
monitoring system (TPMS), which informs the
driver of the tyre inflation status via the "Check
tyre pressure" and "Low tyre pressure" messages
on the display. For a detailed description of the two
messages, see "Warning lights and messages"
chapter. This system comprises a radio frequency
transmitter fitted to each wheel (on the wheel rim
inside the tyre), which is able to send information
on the tyre inflation pressure of each wheel to
the control unit.
WARNING
The presence of TPMS does not
exonerate the driver from regularly
checking the pressure of the tyres and the
spare wheel (see "Wheels" in the
"Maintenance and care" chapter).
WARNING
Sensor malfunctioning fault indications are not
stored and will therefore not be displayed after the
engine has been switched off and then on again. If
the fault conditions persist, the control unit will

Check tyre pressure on pressure gauge F fig. 154
with compressor off to obtain a more precise
reading;❒if after 5 minutes it is still impossible to reach at
least 1.5 bar, disengage the compressor from the
valve and power socket, then move the car
forwards by approx. 10 metres in order to
distribute the sealing fluid inside the tyre evenly,
then repeat the inflation operation;
❒if after this operation it is still impossible after 5
minutes to reach at least 1.8 bar, do not start
driving since the tyre is excessively damaged and
the quick tyre repair kit cannot guarantee proper
hold, contact a Fiat Dealership;
❒if reaching the tyre pressure specified in
paragraph “Inflation pressure” in chapter
“Technical Data”, start driving immediately;
❒after having driven for about 10 minutes, stop
and recheck the tyre pressure; remember to
apply the handbrake;
❒if, on the other hand, the pressure is at least 1.8
bar, restore the correct pressure (with the
engine running and the handbrake applied) and
resume driving;
❒drive with the utmost care to the nearest Fiat
