Operation Driving instructions If the vehicle is parked after being driven on salt-treated roads, the braking efficiency should be tested as soon as possible after driving is resumed. Warning! Standing water Warning! G G Make sure not to endanger any other road users when carrying out these braking maneuvers. The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. ! Do not drive through flooded areas or water of unknown depth. Before driving through water, determine its depth. Never accelerate before driving into water. The bow wave could force water into the engine and auxiliary equipment, thus damaging them. If you must drive through standing water, drive slowly to prevent water from entering the passenger compartment or the engine compartment. Water in these areas could cause damage to electrical components wiring of the engine or transmission or could result in water being ingested by the engine through the air intake, causing severe internal engine damage. Any such damage is not covered by the Mercedes-Benz Limited Warranty. For more information, see "Winter driving" ( page 420). Warning! G If the vehicle becomes stuck in snow, make sure that snow is kept clear of the exhaust pipe and from around the vehicle with the 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. i Select the raised level ( page 281) before driving through standing water. For more information, see "Driving through water" ( page 362). 356
