352Maintenance and care

After driving in emergency mode havetherimscheckedbyaqualified special‐istworkshop withregardtotheir furtheruse.
The defective tire must bereplaced ineverycase.
WithMOExtended tires (run-flat tire),you cancontinuetodriveyourvehicleeven ifthere is atotal loss of pressure in one or more tires. How‐ever,the tire affected must not show any clearlyvisible damage.
You canrecognize MOExtended tiresbytheMOExtended marking which appears onthe sidewall ofthe tire.
Vehicles with tire pressure losswarning sys‐tem:MOExtended tires may only be used in con‐junction withan activated tire pressure losswarning system.
Vehicles with tire pressure monitoring sys‐tem:MOExtended tires may only be used in con‐junction withan activated tire pressure monitor‐ing system.
If a pressure losswarning message appears inthe multifunction display,proceed asfollows:
RCheckthe tirefor damage.
RIf driving on, observethefollowing notes.
Driving distance possible in emergencymode after the pressure losswarning:
Load condition Driving distance pos‐sible in emergencymode
Partially laden50 miles (80 km)
Fully laden19miles (30 km)
The driving distance possible in emergencymode mayvarydepending onthe drivingstyle.Observethe maximum permissible speed of50mph (80 km/h).
If a tire has goneflat and cannot bereplacedwith an MOExtended tire,you can use astand‐ard tire as atemporary measure.
