Notes on electrical fuses
&WARNINGRisk of accident and injurydueto overloaded lines
Ifyou manipulate or bridge afaulty fuse or ifyoureplace it with a fuse with a higheramperage,the electric line could beoverloa‐ded.
This couldresult in afire.
#Alwaysreplacefaulty fuses with speci‐fied new fuses containingthe correctamperage.
*NOTEDamagecausedbyincorrect fuses
Incorrect fuses may cause damagetoelectri‐cal components or systems.
#Only use Mercedes-Benz approvedfuses withthe correct fuserating.
Blown fuses mustbereplaced with fuses ofthesamerating, whichyou canrecognizebythecolor and fuserating. The fuseratings and fur‐
ther informationtobe observed are listed inthefuse assignment diagram.
*NOTEDamageor malfunctions causedbymoisture
Moisture may cause damagetothe electricalsystem or cause ittomalfunction.
#Whenthe fuse box is open, make surethat no moisture can enterthe fusebox.
#When closingthe fuse box, make surethatthe seal ofthe lid is positioned cor‐rectly onthe fuse box.
Ifthe newly inserted fuse also blows, havethecause traced andrectified at aqualified special‐istworkshop, e.g. an authorized Mercedes-BenzCenter.

The tire pressuretable shows therecommendedtire pressurefor all tires approvedforthisvehi‐cle. Therecommended tire pressures applyforcold tires undervarious operating conditions, i.e.loading and/or speed ofthevehicle.
If one or more tire sizes precede a tire pressure,the tire pressure informationfollowing is onlyvalidforthose tire sizes.
The load conditions "partially laden" and "fullyladen" are defined inthetablefor different num‐bersof passengers and amounts of luggage. Theactual number of seats may differ fromthis.
Some tire pressuretables only showtherimdiameter instead ofthe completetire size, e.g.R18. Therim diameter is part ofthe tire size andcan befound onthe tire sidewall (→page449).
Be suretoalso observethefollowing furtherrelated subjects:
RNotes on tire pressure (→page 435)
RTireand Loading Information placard(→page442)
RMaximum tire pressure (→page448)
Checkingtire pressures manually
#Readthe tire pressureforthe current operat‐ing conditions fromtheTireand LoadingInformation placard orthe tire pressuretable. Observethe notes on tire pressure.
#Removethevalve cap ofthe tiretobechecked.
#Pressthe tire pressuregauge securely ontothevalve.
#Readthe tire pressure.
#Ifthe tire pressure is lowerthantherecom‐mendedvalue, increasethe tire pressuretotherecommendedvalue.
#Ifthe tire pressure is higherthantherecom‐mendedvalue,release air.Todo so, pressdownthe metal pin inthevalve, e.g. usingthe tip of a penforexample. Thencheckthetire pressureagain usingthe tire pressuregauge.
#Screwthevalve cap ontothevalve.

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

Maximum tire load:the maximum tire load isthe maximum permissibleweight in kilograms orlbsfor whicha tire is approved.
Maximum permissible tire pressure:maxi‐mum permissible tire pressurefor one tire.
Maximum load on one tire:maximum load onone tire. This is calculatedbydividingthe maxi‐mum axle load of one axlebytwo.
PSI (pounds per square inch):standard unit ofmeasurementfor tire pressure.
Aspectratio:ratio between tire height and tirewidth in percent.
Tirepressure:pressure insidethe tire applyingan outwardforcetoeverysquare inch ofthe tire.The tire pressure is specified in pounds persquare inch (psi), in kilopascals (kPa) or in bar.The tire pressure should only be corrected whenthe tires are cold.
Cold tire pressure:the tires are cold whenthevehicle has been parkedfor at least3 hours
without direct sunlight onthe tires orthevehiclehas been drivenfor lessthan 1 mile (1.6 km).
Tirecontact surface:the part ofthe tirethatcomes into contact with theroad.
Tirebead:the purpose ofthe tire bead istoensurethatthe tire sits securely onthe wheelrim. There are several wire cores inthe tire beadtopreventthe tire fromchanging length onthewheelrim.
Sidewall:the part ofthe tire betweenthe treadandthe tire bead.
Weight of optional equipment:the combinedweight ofthe optional equipmentweighing morethanthereplacedstandard parts and morethan5 lbs (2.3kg).This optional equipment, such ashigh-performance brakes, level control system, aroof luggagerackor high-performance batteries,is not included inthe curbweight andtheweightofthe accessories.
TIN (Tire IdentificationNumber):a uniqueidentification number which can be usedby atire manufacturertoidentify tires,forexample,in a productrecall, andthus identifythe pur‐chasers. The TIN is made up ofthe manufactur‐
er's identity code, tire size, tire type code andthe manufacturing date.
Load-bearing index:the load-bearing index is acodethat containsthe maximum load-bearingcapacity of a tire.
Traction:traction isthe gripresulting from fric‐tion betweenthe tires andtheroad surface.
Wear indicator:narrowbars (treadwear bars)that are distributedoverthe tire contact surface.Ifthe tire tread is level withthe bars,thewearlimit of 1/16in (1.6 mm) has beenreached.
Distribution ofvehicle occupants:distributionofvehicle occupantsover designated seat posi‐tions in avehicle.
Maximum permissible payloadweight:nomi‐nal load and luggage load plus150 lb (68kg)multipliedbythe number of seats inthevehicle.
