The system checks the tire pressure and the tire
te mp erature of the tires ins talled on theve hicle
by means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in thefirs t time they are
driven.
The tire pressure and the tire temp erature
appear in the multifunction display
(
→page 218).
If th ere is a subs tantial pressure loss or if the
tire temp erature is excessive, a warning will be
given:

It is the driver&#39;s responsibility toset the tire
pressure tothere commended cold tire pressure
suitable forth e operating situation. Set the tire
pressure for cold tires using a tire pressure
ga uge. Notethat the cor rect tire pressure forth e
cur rent operating situation must firs t be taught-
in to the tire pressure monitoring sy stem. In most cases,
the tire pressure monitoring sys‐

Wheels and tires

Observethefo llowing when selecting, ins talling
and replacing tires:
ROnly use tires and wheels of the same type
(summer tires, winter tires, MOEx tended
tires) and the same make.
ROnly mount wheels of the same size on one
axle (left and right).
It is only permissible tomount a dif fere nt
wheel size in theeve nt of a flat tire in order
to drive tothe specialist workshop.
ROnly mount tires of the cor rect size onto the
wheels.
RVe hicles with a tire pressure monitoring
sy stem: All mounte d wheels must be equip‐
ped with functioning sensors forth e tire
pressure monitoring sy stem.
RAt temp eratures below 45 °F (7 °C), use win‐
te r tires or all-season tires mar ked M+S for
all wheels.
Wi nter tires bearing thei snowflake sym‐
bol in addition tothe M+S marking pr ovide
th e best possible grip in wintry road condi‐
tions.
RFo r M+S tires, only use tires with the same
tread.
RObser vethe maximum permissible speed for
th e M+S tires mounted.
If th is is below theve hicle&#39;s maximum speed,
th is must be indicated in an appropriate label
in the driver&#39;s field of vision.
RBreak in new tires at moderate speeds for
th efirs t 60 miles (100 km).
RRe place the tires af ter six years at the latest,
re ga rdless of wear.
RWhen replacing with tires that do n otfea‐
ture run-flat characteristics: Vehicles with
MOExtended tires are not equipped with a
