MOExtended tires (tires with run-flat properties)
G WARNING
When driving in emergency mode, the driving characteristics deteriorate, e.g. when cornering, accelerating quickly and when braking. There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers, and driving over obstacles (curbs, potholes, off-road). This applies in particular to a laden vehicle.
Stop driving in emergency mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ® is intervening constantly.
R there are tears in the sidewalls of the tire.
After driving in emergency mode, have the wheel rims checked at a qualified specialist workshop with regard to their further use. The defective tire must be replaced in every case.
With MOExtended tires (tires with run flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tires.
MOExtended tires may only be used in conjunction with an active tire pressure loss warning system or with an active tire pressure monitor.
Z
314
Battery (vehicle)
The maximum driving distance is approximately 50 miles (80 km) when the vehicle is partially laden, and approximately
18 miles (30 km) when the vehicle is fully laden.
In addition to the vehicle load, the driving distance possible depends upon:
R Speed
R
Road condition
R Outside temperature
The driving distance possible in run-flat mode may be reduced by extreme driving conditions/maneuvers, or it can be increased through a moderate style of driving.
The maximum permissible distance which can be driven in run-flat mode is counted from the moment the tire pressure loss warning appears in the multifunction display.
Do not exceed a vehicle speed of 50 mph
(80 km/h).
i When changing or replacing one or all of the tires, note the label "MOExtended".
Take note also of the size specified for the vehicle.
