Ford OURNEO CUSTOM Owner's Manual page 176

You must check the tire pressures
(including the spare tire where applicable)
every two weeks when the tires are cold.
You must inflate the tires to the correct
pressure. See Wheels and Tires (page
164). The tire pressures are also on the tire
inflation pressure label (located on the
edge of driver door or the B-Pillar).
As a driver assistance feature, your vehicle
has a tire pressure monitoring system. A
warning lamp will illuminate when one or
more of the tires are significantly
under-inflated. If the low tire pressure
warning lamp illuminates, you should stop
your vehicle as soon as it is safe to do so,
check the tires and inflate them to the
correct pressure.
Driving on under-inflated tires can:
• Cause them to overheat.
• Lead to tire failure.
• Reduce fuel efficiency.
• Reduce tire life.
• Affect vehicle handling or stopping
ability.
The system is not a substitute for correct
tire maintenance. You must maintain the
correct tire pressures, even if low tire
pressure has not illuminated the warning
lamp.
Your vehicle has a system malfunction
indicator to indicate when the system is
not operating correctly. The malfunction
indicator and low tire pressure warning
lamp have a combined function. When the
system detects a malfunction, the warning
lamp will flash for approximately one
minute and then remain illuminated. This
sequence will occur every time you switch
the ignition on while the malfunction
remains. Have your vehicle checked by an
authorized dealer as soon as possible.
Tourneo Custom/Transit Custom (TTF)
Wheels and Tires
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressures. A
malfunction may occur for a variety of
reasons, including the installation of a
replacement tire or wheel that prevents
the system from functioning correctly.
Always check the tire pressure monitoring
system malfunction warning after
replacing one or more tires or wheels on
your vehicle. Make sure the replacement
tires or wheels allow the system to
continue to function correctly.
Changing Tires With a Tire
Pressure Monitoring System
Note: Each road wheel and tire is equipped
with a tire pressure sensor located inside
the wheel and tire assembly cavity. The
pressure sensor attaches to the valve stem.
The tire covers the pressure sensor and it is
not visible unless you remove the tire. Take
care when changing the tire to avoid
damaging the sensor. Failure to correctly
maintain tire pressures could increase the
risk of tire failure, loss of control, vehicle
rollover and personal injury.
You should always have tires serviced by
an authorized dealer.
