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.
Changing Tires With a Tire
Pressure Monitoring System
You should always have tires serviced by
an authorized dealer.
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.
Note: The spare wheel does not have a
pressure sensor.
Understanding the Tire Pressure
Monitoring System
The system measures the pressure in the
four road tires and sends the tire pressure
readings to your vehicle.
The system detects this lower pressure as
being significantly below the correct
inflation pressure and the warning lamp
illuminates. You must inflate the tires to
the correct pressure.
