Operation Engine compartment Engine compartment Hood Opening Warning! Warning! G G Warning! G Do not pull the release lever while the vehicle is in motion. Otherwise the hood could be forced open by passing air flow. This could cause the hood to come loose and injure you and/or others. If you see flames or smoke coming from the engine compartment, or if the coolant temperature indicator 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. 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. Warning! G Warning! G You could be injured when the hood is open - even when the engine is turned off. Parts of the engine can become very hot. To prevent burns, let the engine cool off completely before touching any components on the vehicle. Comply with all relevant safety precautions. 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 the ignition is "on" and the engine is turned manually. 323
