or
X Depending on the size of the wheel, you
may also be able to secure the faulty wheel
in the emergency spare wheel well. In this
case, you will have to remove the stowage
tray from the emergency spare wheel well
and stow it securely in the luggage com-
partment.
i Do not activate the tyre pressure moni-
tor* until the deflated tyre has been
removed from the vehicle. MOExtended run-flat system*
The MOExtended run-flat system must only
be used in conjunction with the tyre pressure
loss warning system*.
! The maximum permissible distance which
can be driven in run-flat mode depends on
the load in the vehicle. It is 50 km if the
vehicle is partially laden and 30 km if fully
laden.
The maximum range that can be driven in
emergency operation is measured from the
point at which the pressure loss warning
message appears in the multi-function dis-
play. Practical advice
