344 Wheels and tires
The system checks the tire pressure of the tires
installed on the vehicle by means of a tire pres‐
sure sensor.
New tire pressure sensor, e.g. in winter tires, are
automatically taught-in the first time they are
driven.
The tire pressure appears in the multifunction
display ( page 202).

If there is a substantial pressure loss or if the
tire temperature is excessive, a warning will be
given:

It is the driver's responsibility to set the tire
pressure to the recommended cold tire pressure
suitable for the operating situation. Set the tire
pressure for cold tires using a tire pressure
gauge. Note that the correct tire pressure for the
current operating situation must first be taught-
in to the tire pressure monitor.
In most cases, the tire pressure monitoring sys‐
tem will automatically update the new reference
values after you have changed the tire pressure.
You can, however, also update the reference val‐
ues by restarting the tire pressure monitoring
