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 that should be closely observed.

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 shift lever to P (Park).
• Be sure the ignition switch is in the OFF or LOCK position when performing any parts replacement or repairs.
• 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.
• 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.
• 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.
  Because the fuel lines are under high pressure even when the engine is off, it is recommended you visit an INFINITI retailer for service of the fuel filter or fuel lines.

CAUTION
Do not work under the hood while the engine is hot. Turn the engine off and wait until it cools down.
Avoid direct contact with used engine oil and coolant. Improperly disposed of engine oil, coolant, and/or other vehicle fluids can damage the environment. Always conform to local regulations for the disposal of vehicle fluid.

This “8. Do-it-yourself” section gives instructions regarding only those items that are relatively easy for an owner to perform. A genuine INFINITI Service Manual is also available. (See “Owner’s Manual/Service Manual order information” (P.10-24).)

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, it is recommended you have it done by an INFINITI retailer.

ENGINE COOLING SYSTEM
The engine cooling system is filled at the factory with a pre-diluted mixture of 50%Genuine NISSAN Long Life Antifreeze/Coolant (blue) and 50% water to provide year-round anti-freeze and coolant protection. The anti-freeze solution contains rust and corrosion inhibitors. Additional engine cooling system additives are not necessary.

WARNING

• Never remove the radiator cap when the engine is hot. Wait until the engine and radiator cool down. Serious burns could be caused by high-pressure fluid escaping from the radiator. See precautions in “If your vehicle overheats” (P.6-7) of this manual.
• The radiator is equipped with a pressure-type radiator cap. To prevent engine damage, use only a genuine NISSAN radiator cap.

CAUTION

• Never use any cooling system additives such as radiator sealer. Advise may clog the cooling system and cause damage to the engine, transmission and/or cooling system.
• When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent. Genuine NISSAN Long Life Antifreeze/Coolant (blue) is pre-diluted to provide antifreeze protect-ion to −34°F (−37°C). If additional freeze protection is needed due to weather where you operate your vehicle, add Genuine NISSAN Long Life Antifreeze/Coolant (blue) concentrate following the directions on the container. If an equivalent coolant other than Genuine NISSAN Long Life Antifreeze/Coolant (blue) is used, follow the coolant manufacturer’s instructions to maintain mini-mum antifreeze protection to −34°F (−37°C). The use of other types of coolant solutions other than Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent may damage the engine cooling system.
• The life expectancy of the factory-fill coolant is 105,000 miles (168,000 km) or 7 years. Mixing any other type of coolant other than Genuine NISSAN Long Life Antifreeze/Coolant (blue) (or equivalent coolant), including Genuine NISSAN Long Life Antifreeze/ Coolant (green), or the use of non-distilled water will reduce the life expectancy of the factory-fill coolant. Refer to the “9. Maintenance and schedules” section of this manual for more details.

CHECKING ENGINE COOLANT LEVEL
Check the coolant level in the reservoir tank when the engine is running and after it reaches normal operating temperature. If the coolant level is below MIN level, add coolant up to the MAX level . If the reservoir tank is empty, check the coolant level in the radiator when the engine is cold. If there is insufficient coolant in the radiator, fill the radiator with coolant up to the filler cap above the radiator upper hose opening and also add it to the reservoir tank up to the MAX level. Put on the filler cap above the radiator upper hose and with the reservoir cap open, start the engine. Run the engine until it reaches normal operating temperature. Add coolant up to the MAX level. Tighten the cap securely after adding engine coolant.
If the cooling system requires coolant frequently, have it checked. It is recommended you visit an INFINITI retailer for this service.

CHANGING ENGINE COOLANT
It is recommended that major cooling system repairs be performed by an INFINITI retailer. The service procedures can be found in the appropriate INFINITI Service Manual.
Improper servicing can result in reduced heater performance and engine overheating.

WARNING

• To avoid the danger of being scalded, never change the coolant when the engine is hot.
• Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from the radiator.
• Avoid direct skin contact with used coolant. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
• Keep coolant out of reach of children and pets.
• Engine coolant must be disposed of properly Check your local regulations.

INTERCOOLER COOLING SYSTEM

The intercooler cooling system is filled at the factory with a pre-diluted mixture of 50%Genuine NISSAN Long Life Antifreeze/Coolant (blue) and 50% water to provide year-round anti-freeze and coolant protection. The antifreeze solution contains rust and corrosion inhibitors. Additional inter-cooler cooling system additives are not necessary.

WARNING

• Never remove the coolant reservoir cap when the engine is hot. Wait until the engine cools down. Serious burns could be caused by high-pressure fluid escaping from the coolant reservoir.
• The intercooler reservoir is equipped with a pressure-type cap. To prevent engine and intercooler damage, use only a genuine NISSAN intercooler reservoir cap.

CAUTION

• Never use any additives in the coolant such as radiator sealer in the cooling system. This may cause damage to the intercooler.
• When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent. Genuine NISSAN Long Life Antifreeze/Coolant (blue) is pre-diluted to provide antifreeze protection to −34°F(−37°C). If additional freeze protection is needed due to weather where you operate your vehicle, add Genuine NISSAN Long Life Antifreeze/Coolant (blue) concentrate following the directions on the container. If an equivalent coolant other than Genuine NISSAN Long Life Antifreeze/Coolant (blue) is used, follow the coolant manufacturer’s instructions to maintain mini-mum antifreeze protection to −34°F (−37°C). The use of other types of coolant solutions other than Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent may damage the Intercooler cooling system.

CHECKING INTERCOOLER COOLANT LEVEL

Check the coolant level in the reservoir when the engine is cold. If the coolant level is below the MIN level , add coolant to the MAX level .

If the intercooler cooling system frequently requires coolant, have it checked. It is recommended you visit an INFINITI retailer for this service.

CHANGING INTERCOOLER COOLANT

Intercooler coolant is maintenance-free.
If replacement is required, it is recommended you visit an INFINITI retailer for this service.
Improper servicing can result in intercooler overheating.

WARNING
