Restarting the tire pressure monitor When you restart the tire pressure monitor,
the currently set tire pressure are taken as
reference values for monitoring.
In most cases, the tire pressure monitor
detects the new reference values
automatically, e.g. after you have:
R changed the tire pressure
R changed wheels or tires
R installed new wheels or tires
However, you can also define reference
values manually as described here.
Before restarting the tire pressure
monitor:
