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*.
! 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 begins in emergency mode 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).
Warning!
In emergency mode, your vehicle's driving characteristics are diminished in such situations as:
- driving around curves
- while braking
- while accelerating rapidly
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
- the vehicle starts to shake
- smoke develops and you smell rubber
- ESP® is intervening continuously
- 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.
i When replacing individual or all tires on the vehicle, make sure only matching tires marked with "MOExtended" are mounted in the size specified for your vehicle (▷ page 432).
