MAINTENANCE PRECAUTIONS When performing any inspection or maintenance work on your vehicle, always take care to prevent serious accidental injury to yourself or damage to the vehicle. The following are general precautions which should be closely observed. Always wear eye protection whenever you work on your vehicle. If you must run the engine in an enclosed space such as a garage, be sure there is proper ventilation for exhaust gases to escape. Never get under the vehicle while it is supported only by a jack. If it is necessary to work under the vehicle, support it with safety stands. Keep smoking materials, flame and sparks away from fuel tank and the battery. Your vehicle is equipped with an automatic engine cooling fan. It may come on at any time without warning, even if the ignition key is in the OFF position and the engine is not running. To avoid injury, always disconnect the negative battery cable before working near the fan. The fuel filter or fuel lines should be serviced by an INFINITI dealer because the fuel lines are under high pressure even when the engine is off. CAUTION Do not work under the hood while the engine is hot. Turn the engine off and wait until it cools down. Never connect or disconnect the battery or any transistorized component while the ignition switch is in the ON position. Never leave the engine or automatic transmission related component harnesses disconnected while the ignition switch is in the ON position. Avoid direct contact with used engine oil and coolant. Improperly disposed engine oil, and coolant, and/or other vehicle fluids can damage the environment. Always conform to local regulations for disposal of vehicle fluid. WARNING Park the vehicle on a level surface, apply the parking brake securely and block the wheels to prevent the vehicle from moving. Move the selector lever to P (Park). Be sure the ignition switch is in the LOCK position when performing any parts replacement or repairs. If you must work with the engine running, keep your hands, clothing, hair and tools away from moving fans, belts and any other moving parts. It is advisable to secure or remove any loose clothing and remove any jewelry, such as rings, watches, etc. before working on your vehicle. Maintenance and do-it-yourself 8-5
