Warning! If the vehicle becomes stuck in snow, make sure that snow is kept clear of the exhaust pipe and from around the vehicle with engine running. Otherwise, deadly carbon monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death. To assure sufficient fresh air ventilation, open a window slightly on the side of the vehicle not facing the wind. Winter driving Have your vehicle winterized at your authorized Mercedes-Benz Center before the onset of winter. • Change the engine oil if the engine contains an oil which is not approved for winter operation. For viscosity (SAE/CCMC class) and filling quantity, see page 252. • Check engine coolant anticorrosion/ antifreeze concentration. • Additive for the windshield washer and headlamp cleaning system: Add MB Concentrate "S" to a premixed windshield washer solvent/antifreeze which is formulated for below freezing temperatures, see page 195. • Test battery: Battery capacity drops with decreasing ambient temperature. A well charged battery helps to ensure that the engine can be started, even at low ambient temperatures. • Tires: We recommend M+S rated radial-ply tires on all four wheels for the winter season. Observe permissible maximum speed for M+S rated radialply tires and the legal speed limit. Note: In winter operation, the maximum effectiveness of the antilock brake system (ABS) or electronic stability program (ESP) can only be achieved with M+S rated radial-ply tires and/ or snow chains recommended by Mercedes-Benz. Snow chains maximize performance. Driving instructions Instruments and controls Operation Driving 161 Instrument cluster display Practical hints Car care Technical data Index
