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)

\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.

\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.

The tire and informationtable containstherec‐ommended tire pressuresfor cold tires,the max‐imum permissible load andthe maximum per‐missiblevehicle speed.
The tire pressuretable containstherecommen‐ded tire pressuresfor cold tires undervariousoperating conditions, i.e. loading and/or speedofthevehicle.
Increasedvehicleweight duetooptionalequipment:the combinedweight of allstandardand optional equipmentavailableforthevehicle,

Rim:the part ofthe wheel on whichthe tire isinstalled.
GAWR (Gross AxleWeightRating):the GAWRisthe maximum permissible axle load. Theactual load on an axle must neverexceedthegrossaxleweightrating. The gross axleweightrating can befound onthevehicle identificationplate onthe B‑pillar onthe driver's side.
Speedrating:the speedrating is partofthe tireidentification. It specifiesthe speedrangeforwhich a tire is approved.

\nWARNING‑ Risk offireand injury fromantifreeze
If antifreeze comes into contact withhotcomponent parts inthe engine compart‐ment, it may ignite.
Allowthe enginetocool down beforeadding antifreeze.
Makesurethat no antifreeze spills outnexttothefiller opening.
Thoroughly clean off any antifreezefrom component parts beforestartingthevehicle.
