Adding engine oil
\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.
\nWARNINGRisk offireand injury fromengine oil
If engine oil comes into contact withhotcomponent parts inthe engine compart‐ment, it may ignite.
Make surethat no engine oil is spillednexttothefiller opening.
Allowthe enginetocool off andthor‐oughly cleanthe engine oil from compo‐nent parts beforestartingthevehicle.
NOTEEngine damagecausedbyanincorrect oilfilter, incorrect oil or addi‐tives
Do not use engine oils or oilfilterswhich do not correspondtothe specifi‐cationsexplicitly prescribedfortheservice intervals.
Do not alterthe engine oil or oilfilter inordertoachievelongerchange intervalsthan prescribed.
Do not use additives.
352Maintenance and care

Followthe instructions inthe serviceinterval displayregardingthe oilchange.
NOTEDamagecausedbyaddingtoomuch engine oil
Too much engine oil can damagethe engineorthe catalytic converter.
Haveexcess engine oilremoved at aqualified specialistworkshop.
Turncap1counter-clockwise andremoveit.
Add engine oil.
Replace cap1and turn it clockwise asfaras it will go.
Checkthe oil level again (→page 351).
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.
\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.
Maintenance and care353

Parkthevehicle on a level surface.
Checkthe coolanttemperature display intheinstrument cluster.The coolanttemperature must be below158 °F (70 °C).
Slowly turn cap1counter-clockwisetorelieve overpressure.
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 423)
Addingwasherfluidtothe windshieldwasher system
\nWARNINGRisk 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.
\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.
\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.

362Maintenance and care

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.

You can use TIREFIT tire sealanttoseal perfora‐tion damageof upto0.16in (4 mm), particularlythose inthe tire contact surface.You can useTIREFIT in outsidetemperatures downto-4 °F(-20 °C).
\nWARNINGRisk of accident when usingtire sealant.
Inthefollowing situations,the tire sealant isunabletoprovide sufficient breakdown assis‐tance, as it is unabletosealthe tire properly:
RThere are cuts or punctures inthe tirelargerthanthose previously mentioned.
RThe wheelrim is damaged.
RYou havedriven at averylow tire pres‐sure or on aflat tire.
Do not continue driving.
Consult aqualified specialistworkshop.
366Breakdown assistance

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 andthe tiretemperatureappear inthe multifunction display(→page 390).
Ifthere is a substantial pressure loss or ifthetiretemperature isexcessive,you will bewarnedinthefollowingways:

Rviathewwarning lamp inthe instrumentcluster (→page 484)
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 automaticallyupdatethe newreferencevalues afteryou havechangedthe tire pressure.You can, however,also updatethereferenceval‐uesbyrestartingthe tire pressure monitoringsystem manually (→page 391).
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
