acteristics)

cles with MOExtended tyres.

Only operate the tyre inflation compressor
using a 12 V socket, even if the ignition is
turned off (
Y
page 364).
An emergency cut-off ensures that the on-
board voltage does not drop too low. If the on-
board voltage is too low, the power to the
sockets is automatically cut. This ensures
that there is sufficient power to start the
engine.
MOExtended tyres (tyres with run-flat
characteristics)
General notes
With MOExtended tyres (tyres with run-flat char-
acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one
or more tyres. The affected tyre must not show
any clearly visible damage.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the tyre
wall. You will find this marking next to the tyre
size designation, the load-bearing capacity and
the speed index.
MOExtended tyres may only be used in conjunc-
tion with an activated tyre pressure loss warning
system or tyre pressure monitor.
If a pressure loss warning message appears
in the multifunction display:
R
observe the instructions in the display mes-
sages (
Y
page 330)
R
check the tyre for damage
R
if driving on, observe the following notes
The driving distance possible in run-flat mode is
approximately 80 km when the vehicle is parti-
ally laden and approximately 30 km when the
vehicle is fully laden.
