Driving G Warning SmartKey positions SmartKey 131 G Warning Manual transmission: Wait until the vehicle is stationary before removing the SmartKey from the starter switch. The vehicle cannot be steered when the SmartKey is removed from the starter switch. G Warning It is dangerous to shift the automatic transmission out of parking 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 To remove the SmartKey Vehicles with automatic transmission: shift the transmission to position P. 1 Power supply for some consumers, such as the windshield wipers 2 Ignition (power supply for all consumers) and drive position 3 To start the engine Once the ignition is switched on, all the indicator lamps in the instrument cluster light up. The indicator lamps of the low-beam headlamps, high-beam headlamps, turn signal lamps or front fog lamps only light up if the low-beam headlamps, high-beam headlamps, turn signal lamps or front fog lamps are switched on. If an indicator lamp does not light up when the ignition is switched on, check it and replace it if necessary. If an indicator lamp does not go out after starting the engine or lights up while the vehicle is in motion, see (Y page 203). If the SmartKey is in position 0 in the ignition lock for an extended period of time, it can no longer be turned in the ignition lock. The steering is then locked. To unlock, remove the SmartKey and reinsert it in the ignition lock. The steering is locked when you remove the SmartKey from the ignition lock. X Remove the SmartKey when the engine is switched off. The battery may otherwise discharge. Z ! Warm up the engine quickly. Do not use the engine's full performance until it has reached operating temperature. Only shift the automatic transmission to the desired drive position when the vehicle is stationary. Where possible, avoid spinning the drive wheels when pulling away on slippery roads. You could otherwise damage the drive train. ! AMG vehicles: at low engine oil temperatures (below 68 ‡ (+20 †), the maximum engine speed is restricted in order to protect the engine. To protect the engine and maintain smooth engine operation, avoid driving at full throttle when the engine is cold. Driving and parking 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.
