Each tire that is affected by a significant loss
of pressure is highlighted in the pressure dis-
play.
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 automati-
cally, 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 val-
ues manually as described here.
Before restarting the tire pressure moni-
tor:
X Set the tire pressure to the value recom-
mended on the Tire and Loading Informa-
tion placard or the tire pressure table on
the B-pillar on the driver's side
(Y page 288).
Observe the notes on tire pressure when
doing so (Y page 288).
X Make sure that the tire pressure is correct
on all four wheels.
