Controls in detail Automatic transmission Effect ! SmartKey: If you turn off the engine using the SmartKey and remove the SmartKey from the starter switch, the transmission will shift to park position P automatically. Keep in mind that turning off the engine with the SmartKey alone will not automatically shift the transmission to park position P. Effect ì Park position Shift into park position P only when vehicle is stopped. The park position is not intended to serve as a brake when the vehicle is parked. Rather, the driver should always set the parking brake in addition to shifting into park position P to secure the vehicle. If the vehicle's electrical system is malfunctioning, the automatic transmission could remain locked in park position P. Have the vehicle checked as soon as possible by an authorized Mercedes-Benz Light Truck Center. í Reverse gear Shift into reverse gear R only when the vehicle is stopped. ë Neutral No power is transmitted from the engine to the drive axle. When the brakes are released, the vehicle can be moved freely (pushed or towed). To avoid damage to the transmission, never shift into neutral position N while driving. If the ESP® is deactivated or malfunctioning: Shift into neutral position N only if the vehicle is in danger of skidding, e.g. on icy roads. ! KEYLESS-GO*: If you turn off the engine using the KEYLESS-GO* start/stop button and open a front door, the transmission will shift to park position P automatically. Keep in mind that turning off the engine using the KEYLESS-GO* start/stop button alone will not automatically shift the transmission to park position P. i Even though this is possible, make it a practice to always shift into park position P before turning off the engine and remove the SmartKey from the starter switch, or when using KEYLESS-GO*, before turning off the engine with the start/stop button and opening a front door. ê Drive The transmission shifts automatically. All forward gears are available. 196
