Operation Engine compartment Closing Warning! Warning! G Warning! G To help prevent personal injury, stay clear of moving parts when the hood is open and the engine is running. The radiator fan may continue to run for approximately 30 seconds or even restart after the engine has been turned off. Stay clear of fan blades. 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 cranked manually G When closing the hood, use extreme caution not to catch hands or fingers. Be careful that you do not close the hood on anyone. Make sure that the hood is securely engaged before driving off. Do not continue driving if the hood can no longer engage after an accident, for example. The hood could otherwise come loose while the vehicle is in motion and endanger you and/or others. 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 down. If necessary, call the fire department. 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. 542
