Vehicle careOn vehicles with tyre pressure
monitoring
system, screw the adapter
to the valve.
Tyre pressure 3 220 and on the label
on the inside of the fuel filler flap.
The tyre pressure data refer to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare wheel to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible. It must not be
used with run-flat tyres. Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.

Warning If the pressure is too low, this can
result in considerable tyre warm-
up
and internal damage, leading to
tread separation and even to tyre
blow-out at high speeds. Tyre pressure monitoring
system
The tyre pressure monitoring system
continually checks the pressure of all
four wheels when vehicle speed
exceeds a certain limit.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
Otherwise, the tyre pressure will be
monitored by the deflation detection
system 3 177.
The current tyre pressures can be
shown in the Info-Display
3 107. Vehicle messages, tyre pressure
3 101.
Control indicator
w 3 90.
If a complete set of wheels without
sensors is mounted (e.g. four winter
tyres), no error message will be
displayed. The tyre pressure
monitoring system is not operational.
Retrofitting of sensors is possible.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory
approved systems can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
