Operation Driving instructions Warning! G Warning! G Warning! G 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 control loss. Make sure not to endanger any other road users when carrying out these braking maneuvers. Warning! Road salts and chemicals can adversely affect braking efficiency. Increased pedal force may become necessary to produce the normal braking effect. Depressing the brake pedal periodically when traveling at length on salt-strewn roads can 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 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. 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 possible death. To assure sufficient fresh air ventilation, open a window slightly on the side of the vehicle not facing the wind. For more information, see "Winter driving" ( page 336). 286
