&WARNINGRisk of accident when drivingin emergency mode
When driving in emergency mode,the han‐dlingcharacteristics are impaired. e.g. whencornering, when acceleratingstronglyandwhen braking.
#Do notexceedthe permissible maxi‐mum speedfor MOExtended tires.
#Avoid any abruptsteering and drivingmaneuvers aswell as drivingoverobstacles (curbs, pot holes, off-road).This applies, in particular,toa loadedvehicle.
#Stop driving inthe emergency mode ifyou notice:
Rbanging noise
Rvehicle vibration
Rsmoke which smells likerubber
Rcontinuous ESP®intervention
Rcracksin tire sidewalls
#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 appearsonthe sidewall ofthe tire.
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.
