Explanation of maintenance items

Additional information on the following items with “” is found later in this section.

Outside the vehicle

The maintenance items listed here should be performed from time to time, unless otherwise specified. Doors and engine hood: Check that all doors and the engine hood, operate properly. Also ensure that all latches lock securely. Lubricate hinges, latches, latch pins, rollers and links if necessary. Make sure that the secondary latch keeps the hood from opening when the primary latch is released. When driving in areas using road salt or other corrosive materials, check lubrication frequently. Lights: Clean the headlights on a regular basis. Make sure that the headlights, stop lights, tail lights, turn signal lights, and other lights are all operating properly and installed securely. Also check headlight aim. Road wheel nuts (lug nuts): When checking the tires, make sure no wheel nuts are missing, and check for any loose wheel nuts. Tighten if necessary. Tire rotation: Tires should be rotated every 7,500 miles (12,000 km). Tires: Check the pressure with a gauge often and always prior to long distance trips. If necessary, adjust the pressure in all tires, including the spare, to the pressure specified. Check carefully for damage, cuts or excessive wear. Tire Pressure Monitoring System (TPMS) transmitter components: Replace the TPMS transmitter grommet seal, valve core and cap when the tires are replaced due to wear or age. Tire, wheel alignment and balance: If the vehicle should pull to either side while driving on a straight and level road, or if you detect uneven or abnormal tire wear, there may be a need for wheel alignment. If the steering wheel or seat vibrates at normal highway speeds, wheel balancing may be needed. For additional information regarding tires, refer to “Important Tire Safety Information” (US) or “Tire Safety Information” (Canada) in the INFINITI Warranty Information Booklet. Windshield: Clean the windshield on a regular basis. Check the windshield at least every six months for cracks or other damage. Have a damaged windshield repaired by a qualified repair facility. Windshield wiper blades: Check for cracks or wear if they do not wipe properly.

Inside the vehicle

The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the vehicle, etc. Accelerator pedal: Check the pedal for smooth operation and make sure the pedal does not catch or require uneven effort.

Keep the floor mat away from the pedal. Automatic transmission P (Park) mechanism: On a fairly steep hill, check that your vehicle is held securely with the selector lever in the P (Park) position without applying any brakes. Brake pedal: Check the pedal for smooth operation. If the brake pedal suddenly goes down further than normal, the pedal feels spongy or the vehicle seems to take longer to stop, see an INFINITI retailer immediately. Keep the floor mat away from the pedal. Brakes: Check that the brakes do not pull the vehicle to one side when applied. Parking brake: Check the parking brake operation regularly. The vehicle should be securely held on a fairly steep hill with only the parking brake applied. If the parking brake needs adjusted, see an INFINITI retailer. Seat belts: Check that all parts of the seat belt system (for example, buckles, anchors, adjuster and retractors) operate properly and smoothly, and are installed securely. Check the belt webbing for cuts, fraying, wear or damage. Seats: Check seat position controls such as seat adjusters, seatback recliner, etc. to ensure they operate smoothly and that all latches lock securely in every position. Check that the head restraints/headrests move up and down smoothly and that the locks (if so equipped) hold securely in all latched positions. Steering wheel: Check for changes in the steering conditions, such as excessive free play, hard steering or strange noises. Warning lights and chimes: Make sure that all warning lights and chimes are operating properly. Windshield defroster: Check that the air comes out of the defroster outlets properly and in sufficient quantity when operating the heater or air conditioner. Windshield wiper and washer: Check that the wipers and washer operate properly and that the wipers do not streak. Under the hood and vehicle The maintenance items listed here should be checked periodically (for example, each time you check the engine oil or refuel). Battery: Check the fluid level in each cell. It should be between the MAX and MIN lines. Vehicles operated in high temperatures or under severe condition require frequent checks of the battery fluid level. Brake fluid level: Make sure that the brake fluid level is between the MAX and MIN lines on the reservoir. Engine coolant level: Check the coolant level when the engine is cold. Engine drive belts: Make sure that no belt is frayed, worn, cracked or oily. Engine oil level: Check the level after parking the vehicle on a level spot and turning off the engine. Wait more than 15 minutes for the oil to drain back into the oil pan. Exhaust system: Make sure there are no loose supports, cracks or holes. If the sound of the exhaust seems unusual or there is a smell of exhaust fumes, immediately have the exhaust system inspected by an INFINITI retailer. (See “Precautions when starting and driving” in the “5. Starting and driving” section for exhaust gas (carbon monoxide).). Fluid leaks: Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle has been parked for a while. Water dripping from the air conditioner after use is normal. If you should notice any leaks or if gasoline fumes are evident, check for the cause and have it corrected immediately. Power steering fluid level and lines: Check the level when the fluid is cold, with the engine off. Check the lines for proper attachment, leaks, cracks, etc. Radiator and hoses: Check the front of the radiator and clean off any dirt, insects, leaves, etc., that may have accumulated. Make sure the hoses have no cracks, deformation, rot or loose connections. Underbody: The underbody is frequently exposed to corrosive substances such as those used on icy roads or to control dust. It is very important to remove these substances, otherwise rust will form on the floor pan, frame, fuel lines and around the exhaust system. At the end of winter, the underbody should be thoroughly flushed with plain water, being careful to clean those areas where mud and dirt may accumulate. For additional information, see “Cleaning exterior” in the “7. Appearance and care” section. Windshield washer fluid: Check that there is adequate fluid in the reservoir.
