responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level at which the low tire
pressure indicator lamp of the TPMS lights up.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure indicator lamp. When the
system detects a malfunction, the indicator
lamp will flash for approximately 1 minute and
then remain illuminated. This sequence will
continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the
malfunction indicator is lit, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of
incompatible replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction indicator after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
i If the tire pressure monitoring system
malfunctions, it may take up to 10 minutes
before the malfunction is displayed to you
by the tire pressure warning lamp flashing
for 60 seconds and then remaining lit.
When the error has been rectified, the tire
pressure warning lamp goes out after a few
minutes of driving.
Information on tire pressures is displayed in
the multifunction display. After a few minutes
of driving, the current tire pressure of each
tire is shown in the multifunction display.
i The tire pressure values in the on-board
computer may deviate from the inflation
pressure as measured using a tire pressure
checker at the filling station. The tire
pressures shown in the on-board computer
refer to pressures at sea level. At highaltitudes, a tire pressure checker will
display a higher tire pressure than the on-
board computer. In this case do not reduce
the tire pressure.
i If radio transmitting equipment (e.g. radio
headphones, a two-way radio) is operated
in or near the vehicle, this can lead to the
function of the tire pressure monitor being
impaired.

If the vehicle has been parked for longer than
20 minutes and subsequently you have not
driven faster than 15 mph (25 km/h), the
Tire pressure displayed after
driving for a few minutes message is
shown.
After a teach-in process, the tire pressure
monitor automatically detects new wheels or
new sensors. As long as it is not possible to
