Risk of accident
The wheel bolts may work loose if they are
not tightened to a tightening torque of
110 Nm. For this reason, you should have
the tightening torque checked as soon as
possible after a wheel change.
Turn the jack back to its initial position
and return it and the rest of the vehicle
tool kit to the boot.
MOE emergency run-flat system*
You can only use the MOE emergency run-
flat system in conjunction with the tyre
pressure loss warning.
!
The maximum distance you may cover in
run-flat mode depends on the vehicle load. It is
50 km if the vehicle is partially laden and 30 km
if it is fully laden.
The maximum distance that may be driven in run-
flat mode begins from the time the tyre pressure
loss warning appears in the multi-function dis-
play.
You must not exceed a maximum speed of
80 km/h.
