Operation Engine compartment During all seasons, add MB Windshield Washer Concentrate "MB SummerFit" to water. Premix the windshield washer fluid in a suitable container. Warning! Use the tab to pull cap 1 upwards. Refill the reservoir with MB Windshield Washer Concentrate "MB SummerFit" and water (or commercially available premixed windshield washer solvent/antifreeze, depending on ambient temperatures). Battery Your vehicle's battery is located in the engine compartment. The battery should always be sufficiently charged in order to achieve its rated service life. Refer to the Maintenance Booklet for battery maintenance intervals. If you use your vehicle mostly for short-distance trips, you will need to have the battery charge checked more frequently. When replacing the battery, always use batteries approved by Mercedes-Benz. If you do not intend to operate your vehicle for an extended period of time, consult an authorized Mercedes-Benz Center about steps you need to observe. G Washer solvent/antifreeze is highly flammable. Do not spill washer solvent/antifreeze on hot engine parts, because it may ignite and burn. You could be seriously burned. ! Always use washer solvent/antifreeze where temperatures may fall below freezing point. Failure to do so could result in damage to the washer system/reservoir. ! Only use washer fluid which is suitable for plastic lenses. Improper washer fluid can damage the plastic lenses of the headlamps. For more information, see "Windshield washer system and headlamp cleaning system*" ( page 458). 302
