Tread Depth; Changing Tyre And Wheel Size; Wheel Covers - Fiat DOBLO Owner's Handbook Manual

3. Initialise the deflation detection
system: If the vehicle has a graphic
info display, press F for three
seconds. If the vehicle has a colour
info display, the initialisation is done
in the vehicle personalisation 3 89.
4. Reset is confirmed by pop-up
indication.
After initialisation system automatically
calibrates to new tyre pressures during
driving. After longer drive the system will
adopt and monitor new pressures.
Always check tyre pressure with cold
tyres.
System has to be reinitialised when:
● Tyre pressure has been changed
● Load condition has been changed
● Wheels have been swapped or
exchanged
The system will not warn instantaneously
on a tyre blow out or a rapid deflation.
This is due to required calculation time.

Tread depth

Check tread depth at regular intervals.
For safety reasons, it is recommended
that the tread depth of the tyres on one
axle should not vary by more than
2 mm.
The legally permissible minimum tread
depth (1.6 mm) has been reached when
the tread has worn down as far as one of
the tread wear indicators (TWI). Their
position is indicated by markings on the
sidewall.
If there is more wear at the front than the
rear, swap round front wheels and rear
wheels periodically. Ensure that the
direction of rotation of the wheels
remains the same.
Tyres age, even if they are not used. We
recommend tyre replacement every
six years.

Changing tyre and wheel size

If tyres of a different size than those fitted
at the factory are used, it may be
necessary to reprogramme systems and
make other vehicle modifications.
Have the label with tyre pressures
replaced.

WARNING
The use of unsuitable tyres or wheels may
lead to accidents and will invalidate the
vehicle operating permit.

Wheel covers

Wheel covers and tyres that are factory
approved for the respective vehicle and
comply with all of the relevant wheel and
tyre combination requirements must be
used.
If the wheel covers and tyres used are not
factory approved, the tyres must not
have a rim protection ridge.
Wheel covers must not impair brake
cooling.

WARNING
Use of unsuitable tyres or wheel covers
could lead to sudden pressure loss and
thereby accidents.
Vehicles with steel wheels: When using
locking wheel nuts, do not attach wheel
covers.
