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. See When
the Temporary Spare Tire is Installed
in this section.
How Temperature Affects the Tire
Pressures
Under normal driving conditions tire
pressures may increase by up to 0.3 bar
from a cold start situation.
If the vehicle is stationary overnight and
the temperature significantly lower than
the daytime temperature, tire pressures
may decrease by up to 0.2 bar when there
is a drop in the ambient temperature of
31°F (17°C) or more. The system detects
this pressure decrease as being
significantly below the correct inflation
pressure and the warning lamp illuminates.
When Inflating Tires
When inflating the tires the system may
not respond immediately to the air added
to the tires.
Only inflate tires when they are cold.
If the warning lamp is on:
•
Check each tire to verify that none are
flat.
•
If one or more tires are flat, repair as
necessary.

When Changing Tires
E142549
You should always have tires serviced by
an authorized dealer.
Note: Each road wheel and tire is fitted 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 the tire is removed. Take care
when changing the tire to avoid damaging
the sensor.
When Changing Wheels
When changing the wheels of your vehicle,
the tire pressure monitoring system needs
to re-learn the tire pressure sensors. To
achieve this perform the following:
1.
2. Park your vehicle for at least 20
148
Check the tire pressures and inflate all
tires to the correct pressure. See
Technical Specifications (page 157).
Carry out the tire pressure monitoring
system reset procedure.
Make sure all tires are inflated to the
proper pressure. If not, inflate the tires
to the correct pressure. See Technical
Specifications (page 157).
