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

Restarting the tire pressure monitor

When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamps go 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

reference values manually as described here.
The tire pressure monitor then monitors the
new tire pressure values.
