Driving instructions Winter driving instructions G Warning! If the vehicle becomes stuck in snow, make sure 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. 243 bring road-salt-impaired braking efficiency back to normal. 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. G Warning! G Warning! Driving instructions Drive sensibly - save fuel To save fuel you should: RKeep 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. The road may still be icy, especially in wooded areas or on bridges. tires at the recommended inflation pressures. unnecessary loads. roof rack when not in use. RRemove RRemove RAllow G Warning! On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of loss of control. engine to warm up under low load use. RAvoid RHave frequent acceleration and deceleration. all maintenance work performed at the intervals specified in the Maintenance Booklet and as required by the Maintenance system. Contact an authorized Mercedes-Benz Center. The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering maneuvers. Do not use the cruise control system under such conditions. When the vehicle is in danger of skidding, shift the automatic transmission to neutral position N. Try to keep the vehicle under control by corrective steering action. Fuel consumption is also increased by driving in cold weather, in stop-and-go traffic, on short trips and in mountainous areas. i For information on driving with snow chains, see "Snow chains" (Y page 242). Road salts and chemicals can adversely affect braking efficiency. Increased pedal force may become necessary to produce the normal brake effect. Depressing the brake pedal periodically when traveling at length on salt-strewn roads can Drinking and driving G Warning! Drinking and driving and/or taking drugs and driving are very dangerous combinations. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgment. Z Operation Make sure not to endanger any other road users when carrying out these braking maneuvers.
