Operation 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 gauge indicates that the engine is overheated, do not open the hood. Move away from the 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 also start at any time automatically, even after the SmartKey has been removed from the starter switch. Stay clear of fan blades. Warning! G Warning! Warning! The exhaust areas on the engine hood and between the doors and front wheels get very hot. Avoid contact with them, otherwise there is the risk of severe burns. G 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 ignition is "on" and the engine is turned manually 250
