Vehicles with steering wheel buttons: if the
wheel positions on the vehicle are rotated, the
tire pressures may be displayed for the wrong
positions for a short time. This is rectified after
a few minutes of driving; the tire pressures are
then displayed for the correct positions.
Restarting the tire pressure monitor General notes
When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamp goes out. The monitor uses the
currently set tire pressures as the reference
values for monitoring. In most cases, the tire
pressure monitor will automatically detect the
new reference values after you have changed
the tire pressure. However, you can also set
reference values manually as described here.
The tire pressure monitor then monitors the
new tire pressure values.
