&WARNINGRisk of burns from hot com‐ponent parts inthe engine compartment
Certain component parts inthe engine com‐partment can beveryhot, e.g.the engine,the cooler and parts oftheexhaust system.
#Letthe engine cool down and onlytouchthe component parts describedasfollows.
&WARNINGDanger of burns when open‐ingthe hood
Ifyou openthe hood whenthe engine hasoverheated or during afireinthe enginecompartment,you could come into contactwith hotgases orother escaping operatingfluids.
#Before openingthe hood, allowtheenginetocool down.

#Observethe information andwarningnotes on MOExtended tires (run-flattires).
Intheevent of aflat tire,thefollowing optionsareavailable depending onyourvehicle's equip‐ment:
RVehicles with MOExtended tires:it is pos‐sibletocontinuethe journeyfor a shortperiod of time. Make sureyou observethenotes on MOExtended tires (run-flat tire)(→page414).
RVehicles with a TIREFIT kit:you canrepairthe tires sothat it is possibletocontinuethejourneyfor a short period of time.Todothis,usethe TIREFIT kit (→page415).

Notes on MOExtended tires (run-flat tire)
&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.

The systemchecksthe tire pressure andthe tiretemperature ofthe tires installed onthevehiclebymeans of a tire pressuresensor.
New tire pressure sensors, e.g. in winter tires,are automaticallytaught-in duringthefirst jour‐neytheyare used.
The tire pressure appears inthe multifunctiondisplay (→page 255).
Ifthere is a substantial pressure loss or ifthetiretemperature isexcessive,you will bewarnedinthefollowingways:
Rvia display messages (→page511)
Rviathewwarning lamp inthe instrumentcluster (→page 533)
The tire pressuremonitoring system is only anaid. It isthe driver'sresponsibilitytosetthe tirepressuretotherecommended cold tire pressuresuitableforthe operating situation. Setthe tirepressurefor cold tires using a tire pressuregauge. Notethatthe correct tire pressureforthecurrent operating situation mustfirst betaught-intothe tire pressure monitoring system.
In most cases,the tire pressure monitoring sys‐tem will automatically updatethe newreferencevalues afteryou havechangedthe tire pressure.You can, however,also updatethereferenceval‐uesbyrestartingthe tire pressure monitoringsystem manually (→page441).
System limitations
The system may be impaired or may not functioninthefollowing situations:
RIfthe tire pressure is set incorrectly
RIfthere is a sudden pressure loss caused,forexample,byaforeign object penetratingthetire
RIfthere is a malfunction causedbyanotherradio signal source
