Notes on MOExtended tyres (run-flat tyres)
& WARNING Risk of accident when driving
in emergency mode
When driving in emergency mode, the han‐
dling characteristics are impaired. e.g. when
cornering, when accelerating strongly and
when braking.
Do not exceed the permissible maxi‐
#
mum speed.
Avoid any abrupt steering and driving
#
maneuvers as well as driving over
obstacles (curbs, pot holes, off-road).
This applies, in particular, to a loaded
vehicle.
Stop driving in the emergency mode if
#
you notice:
banging noise
R
vehicle vibration
R
smoke which smells like rubber
R
®
R continuous ESP intervention
cracks in tire side walls
R
After driving in emergency mode have
#
the rims checked by a qualified special‐
ist workshop with regard to their further
use.
The defective tire must be replaced in
#
every case.
With MOExtended tyres (run-flat tyres), you can
continue to drive your vehicle even if there is a
total loss of pressure in one or more tyres. How‐
ever, the tyre affected must not show any clearly
visible damage.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the side
wall of the tyre.
Vehicles with tyre pressure loss warning sys‐
tem: MOExtended tyres may only be used in
conjunction with an activated tyre pressure loss
warning system.
Vehicles with tyre pressure monitoring sys‐
tem: MOExtended tyres may only be used in
conjunction with an activated tyre pressure mon‐
itoring system.
