Risk of accident
Replac edamaged or corroded wheel bolts.
Never oil or grease wheel bolts. This could
cause the bolts to loosen in the wheel hub. G
Risk of accident
If aw heel hub thread is damaged, you must
not drive the vehicle any further. Consult a

Risk of accident
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes -Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz vehicles and the
respective wheel. Other wheel bolts could
work loose or damage the brak esystem.

i When you are driving with the emergency
spare wheel fitted, the tyre pressure loss warning system cannot function reliably.
Only restart the tyre pressure loss warning
system when the defective wheel has been
replaced with
anew wheel. MOExtended run-
flat system
Th eM OEx tended run-flat system allo wsyou
to continue driving the vehicle even when one
or more tyres los eall air pressure.
The MOExtended run-flat system may only be
used in conjunction with the activated tyre
pressure loss warnin gsystem or with the acti-
vated tyre pressure monitor.
The maximum permissible distance which
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure los swarning
appears in the multifunction displ ay.
Yo um ust not exceed amaximum spee dof
80 km/h. G
Ris
kofa ccident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to alarge
exten tonthe loads placed on the vehicle. It
can be shorter due to high speeds, aheavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc.,
or further if you driv ecarefully and conserva-
tively. 284
