Moextended System - Mercedes-Benz 2009 M-Class Operator's Manual

MOExtended system

The MOExtended system allows you to
continue driving your vehicle even if there is
a total loss of pressure in one or more tires.
You may only use the MOExtended system in
conjunction with the Run Flat Indicator
( Y page 254) or the TPMS ( Y page 255).
The maximum distance in emergency mode
depends on the vehicle's load. It is 30 miles
(50 km) if the vehicle is partially loaded and
18 miles (30 km) if the vehicle is fully loaded.
The point at which the maximum driving
distance in emergency mode begins is when
the warning message appears in the
multifunction display indicating that there is
a loss of tire inflation pressure.

Do not exceed the maximum speed of
50 mph (80 km/h).
G Warning!
In emergency mode, your vehicle's driving
characteristics are diminished in such
situations as:
driving around curves
R
while braking
R
while accelerating rapidly
R
Therefore, your driving style must be
adapted accordingly. Avoid abrupt steering
and driving maneuvers, as well as driving
over obstacles (road curbs, potholes, or off-
road areas). This is especially important if
the vehicle is heavily loaded.
The emergency driving distance that can be
achieved greatly depends on the demands
placed on the vehicle. Depending on speed,
load, driving maneuvers, road conditions,
outside temperature, etc., the distance can
be significantly shorter or, if the vehicle is
driven cautiously, somewhat longer.
Do not continue driving in emergency mode
if
you notice knocking sounds
R
the vehicle starts to shake
R
smoke develops and you smell rubber
R

ESP is intervening continuously
R
you notice tears on the tire sidewalls

After driving in emergency mode, you must
have the rims inspected by an authorized
Mercedes-Benz Center to check if they are
suitable for further use. The failed tire must
be replaced in any case.
When replacing individual or all tires on the
vehicle, make sure only tires marked with
Practical hints
"MOExtended" are mounted in the size
