Engine Compartment
Safety Guidelines
- Keep smoking materials, flame, and sparks away from fuel and battery.
- Never connect or disconnect either the battery or any transistorised component connector while the ignition switch is ON.
- Never leave the engine or transmission-related component harness connector disconnected while the ignition is ON.
- On petrol engine models with the multiport fuel injection (MFI) system, the fuel filter or fuel lines should be serviced by a NISSAN dealer or qualified workshop because the fuel lines are under high pressure even when the engine is off.
- Always wear eye protection when you work on your vehicle.
- Failure to follow these or other common sense guidelines may lead to serious injury or vehicle damage.
Improperly disposed engine oil and/or other vehicle fluids can pollute the environment. Always conform to local regulations for disposal of vehicle fluids.
This section gives instructions regarding only those items which are relatively easy for an owner to perform. You should be aware that incomplete or improper servicing may result in operating difficulties or excessive emissions, and could affect your warranty coverage. If in doubt about any servicing, have it done by your NISSAN dealer or qualified workshop.

Engine Coolant System
WARNING:
- Never remove the engine coolant reservoir cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from the engine coolant reservoir. Wait until the engine and radiator have cooled down.
- Engine coolant is poisonous and should be stored carefully in marked containers out of the reach of children.
The engine cooling system is filled at the factory with a high-quality, year-round, and extended-life engine coolant. The high-quality engine coolant contains specific solutions effective for anti-corrosion and anti-freeze functions. Therefore, additional cooling system additives are not necessary.
CAUTION:
- Never use any cooling system additives such as radiator sealer. Additives may clog the cooling system and cause damage to the engine, transmission, and/or cooling system.
- When adding or replacing engine coolant, be sure to use Genuine NISSAN engine coolant or equivalent in quality with the proper mixture ratio. The use of other types of coolant solutions may damage the engine cooling system.

Checking Engine Coolant Level
Check the coolant level in the reservoir when the engine is cold. If the coolant level is below MIN, add coolant up to the MAX level.
CAUTION: If the cooling system frequently requires coolant, have it checked by a NISSAN dealer or qualified workshop.
Changing Engine Coolant
Major cooling system repairs should be performed by a NISSAN dealer or qualified workshop. The service procedures can be found in the appropriate NISSAN Service Manual.
When checking or replacement is required, NISSAN recommends contacting a NISSAN dealer or qualified workshop for servicing. Improper servicing or engine coolant change can result in reduced heater performance and engine overheating.
WARNING:
- Never remove the engine coolant reservoir cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from the reservoir. Wait until the engine and radiator have cooled down.
- To avoid the danger of being scalded, never change the coolant when the engine is hot.
- Avoid direct skin contact with used coolant. If skin contact is made, wash thoroughly with soap or hand cleaner and plenty of water as soon as possible.
- Keep coolant out of reach of children and pets. Engine coolant must be disposed of properly. Check your local regulations.
Checking Engine Oil Level
CAUTION: The oil level should be checked regularly. Operating with an insufficient amount of oil can damage the engine, and such damage is not covered by warranty.
NOTE: Some models use the Oil Condition Supervisor (OCS) function. Other models have a service reminder manually set by the user. For more details, see “[Maintenance]” (P.91).
