Operation Engine compartment Closing Warning! Engine oil Warning! G If you see flames or smoke coming from the engine compartment, or if the coolant temperature gauge indicates that the engine is overheated, do not open the hood. Move away from vehicle and do not open the hood until the engine has cooled. If necessary, call the fire department. G Be careful that you do not close the hood on anyone. The amount of oil your engine needs will depend on a number of factors, including driving style. Higher oil consumption can occur when the vehicle is new the vehicle is driven frequently at higher engine speeds Engine oil consumption checks should only be made after the vehicle break-in period. Let the hood drop from a height of approximately 1 ft (30 cm). The hood will lock audibly. Check to make sure the hood is fully closed. If you can raise the hood at a point above the headlamps, then it is not properly closed. Open it again and let it drop with somewhat greater force. Warning! G The engine is equipped with a transistorized ignition system. Because of the high voltage it is dangerous to touch any components (ignition coils, spark plug sockets, diagnostic socket) of the ignition system with the engine running while starting the engine if ignition is "on" and the engine is turned manually i Do not use any special lubricant additives, as these may damage the drive assemblies. Using special additives not approved by Mercedes-Benz will restrict your warranty entitlement. More information on this subject is available at any Mercedes-Benz Center. 279
