Nissan Maxima Owners Manual: 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. The fluid should be at the bottom of the filler opening.
Vehicles operated in high temperatures or under severe conditions require frequent checks of the battery fluid level.
Care should be taken to avoid situations that can lead to potential battery discharge and potential no-start conditions such as: 1. Installation or extended use of electronic accessories that consume battery power when the engine is not running (Phone chargers, GPS, DVD players, etc.).
2. Vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to be charged to maintain battery health.
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 the drive belts are not 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. It is recommended that you visit a NISSAN dealer for this service. For additional information, refer to "Exhaust gas (carbon monoxide)" in the "Starting and driving" section of this manual.
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 fuel 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 may 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, refer to the "Appearance and care" section of this manual.
Windshield-washer fluid*: Check that there is adequate fluid in the reservoir.
