pressure warning lamp to inform you of the
malfunction by flashing for approximately one
minute and then remaining lit. When the fault
has been rectified, the tyre pressure warning
lamp goes out after you have driven for a few
minutes.
The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at a filling station using a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pressure
values indicated by a pressure gauge are
higher than those shown by the on-board
computer. In this case, do not reduce the tyre
pressures.
The operation of the tyre pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.

After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the
Tyre
pressure monitor active
display mes-
sage is shown instead of the tyre pressure
display. The tyre pressures are already being
monitored.

If an emergency spare wheel is fitted, the
system may continue to show the tyre pres-
sure of the wheel that has been removed
for a few minutes. If this occurs, note that
the value displayed for the position where
the spare wheel is fitted is not the same as
the current tyre pressure of the emergency
spare wheel.
Warning messages of the tyre pressure
monitor
If the tyre pressure monitor detects a pres-
sure loss in one or more tyres, a warning mes-
sage is shown in the multifunction display and
the yellow tyre pressure monitor warning light
comes on.

If the
Please correct tyre pressure
message appears in the multifunction dis-
play, the tyre pressure in at least one tyre
is too low and must be corrected at the next
opportunity.
R
If the
Tyre pressure Check tyre(s)
message appears in the multifunction dis-
play, the tyre pressure in one or more tyres
has dropped significantly and the tyres
must be checked.
R
If the
Tyre pressure Caution, tyre
defect
message appears in the multifunc-
tion display, the tyre pressure in one or
more tyres has dropped suddenly and the
tyres must be checked.

If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. This is rectified after a few
minutes of driving and the tyre pressures
are displayed for the correct positions.
