Checking coolant level
\nWARNINGRisk of burns from hot com‐ponent parts inthe engine compartment
Certain components inthe engine compart‐ment can beveryhot, e.g.the engine,theradiator and parts oftheexhaust system.
Allowthe enginetocool down and onlytouch component parts described inthefollowing.
\nWARNINGDanger 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.
Intheevent of afireinthe engine com‐partment,keepthe hood closed andcallthefireservice.
\nWARNINGRisk of scalding from hotcoolant
The engine cooling system is pressurized,particularly whenthe engine iswarm. Ifyouopenthe cap,you could be scaldedbyhotcoolant spraying out.
Letthe engine cool down before open‐ingthe cap.
When openingthe cap,wear protectivegloves and safetyglasses.
Openthe cap slowlytorelease pres‐sure.
Parkthevehicle on a level surface.
Checkthe coolanttemperature display intheinstrument cluster.The coolanttemperature must be below158 °F (70 °C).
Slowly turn cap1counter-clockwisetorelieve overpressure.
Maintenance and care357

Continue turning cap1counter-clockwiseandremoveit.
The coolant level is correct:
RIfthe engine is cold, uptomarker bar2
RIfthe engine iswarm, upto0.6 in (1.5 cm)over marker bar2
If necessary,add coolantthat has beenapprovedbyMercedes-Benz.RFurther information on coolant(page 429).

Before openingthe hood, allowtheenginetocool down.
Intheevent of afireinthe engine com‐partment,keepthe hood closed andcallthefireservice.
\nWARNING‑ Risk offireand injury fromwindshieldwasher concentrate
Windshieldwasher concentrate is highlyflammable. It could ignite if it comes intocontact withhot engine component parts ortheexhaust system.
Make surethat no windshieldwasherconcentrate spills out nexttothefilleropening.
Removecap1bythetab.
Addwasherfluid.
Keepingthe air-water duct free
Keepthe area betweenthe hood andthewindshield free of deposits, e.g. ice, snowand leaves.

Maximumweight ofthe ladenvehicle:themaximumweight isthe sum ofthe curbweightofthevehicle,theweight ofthe accessories,themaximum load andtheweight of optional equip‐ment installed atthefactory.
Kilopascal (kPa):metric unitfor tire pressure.6.9 kPa correspondsto1 psi. Another unitfortire pressureis bar.100 kilopascal (kPa) equals1 bar.
Load index:in additiontothe load-bearingindex,the load index may also be imprinted onthe sidewall ofthe tire. This specifiesthe load-bearing capacity ofthe tire more precisely.
Curbweight:theweight of avehicle withstand‐ard equipment includingthe maximum capacityof fuel, oil and coolant. It also includesthe airconditioning system and optional equipment ifthese are installed onthevehicle, but does notinclude passengers or luggage.
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 hourswithout 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 wheel
rim. 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.
