114 Automatic transmission Automatic transmission Introduction For information on driving with an automatic transmission, see "Driving and parking" (Y page 108). Gear selector lever Controls in detail G Warning! Make sure absolutely no objects are obstructing the pedals' range of movement. Keep the driver's footwell clear of all obstacles. If there are any floormats or carpets in the footwell, make sure the pedals still have sufficient clearance. During sudden driving or braking maneuvers the objects could get caught between the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury. Gearshift pattern for automatic transmission : Button for selecting park position P j Park position k Reverse gear i Neutral position h Drive position ! Allow the engine to warm up under low load use. Do not place full load on the engine until the operating temperature has been reached. Avoid spinning of a drive wheel for an extended period when driving off on slippery road surfaces. This may cause serious damage to the engine and the drivetrain which is not covered by the Mercedes-Benz Limited Warranty. i During the brief warm-up, transmission upshifting is delayed. This allows the catalytic converter (gasoline engine) or oxidation catalyst (diesel engine) to heat up more quickly to operating temperature. It is dangerous to shift the automatic transmission out of park position P or neutral position N if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal. G Warning! ! The vehicle must be stopped when you shift the automatic transmission Rdirectly between drive position D and reverse gear R Rdirectly between reverse gear R and drive position D into park position P Rdirectly Otherwise the automatic transmission could be damaged. When trying to free a vehicle stuck in mud or snow, see "Rocking the vehicle" (Y page 118).
