Nissan vehicles are manufactured using the latest technology and under the strictest quality control standards. They are also designed to minimize maintenance requirements with longer service intervals to save you both time and money.

However, scheduled maintenance is necessary to ensure your Nissan vehicle operates properly and efficiently for the reasons listed below:

• Lubricants
  Your Nissan vehicle uses various kinds of oils and fluids, including engine oil, transmission fluid, differential fluid, battery fluid, and engine coolant. These oils and fluids play very important roles, such as lubricating and cooling the vehicle and preventing corrosion. Periodically they need to be properly refilled or replaced.
  
  
• Rubber parts
  Hoses, belts and boots use rubber in their construction which can deteriorate with age. They need to be replaced with new ones if they show signs of wear.
  
  
• Normal deterioration
  Vehicles are equipped with many parts for which it is impossible to avoid normal wear and tear such as tyres brake pads, clutch discs, etc. They are indispensable for basic vehicle functions and must be replaced periodically.

Failure to perform scheduled maintenance may result in reduced vehicle performance or possible breakdowns, as well as exclusion from warranty coverage.

The maintenance schedule is defined based on our careful experimentation on the life span of parts or lubricants that require regular replacement. Therefore, please make sure that your Nissan vehicle receives proper maintenance care by following the instructions in your Warranty Information & Maintenance Booklet. At the same time, it is necessary for day-to-day vehicle operation checks to be performed by you or on your behalf as mentioned under the "General Maintenance" heading in the "Maintenance and do-it-yourself" section in the Owner's Manual.

We appreciate your understanding of the importance of this information and trust you will enjoy a long and satisfying service experience at your Nissan Dealer.

Scheduled maintenance
There are two types of maintenance schedules. A Sales Person or Service Adviser at your Nissan dealer will explain to you which type of maintenance schedule you should follow depending on your driving habits, climatic conditions in your area, etc. The two schedules and their conditions are described below:

Maintenance Schedule for Severe Driving Conditions (for vehicles first registered after June 2001)
If you primarily drive your vehicle under one or more of the conditions listed below, please follow the "Maintenance Under Severe Driving Conditions" column of the maintenance section of your Customer Information Booklet.

A: Driving in dusty conditions
B: Repeatedly driving short distances
C: Towing a trailer or caravan
D: Extensive idling
E: Driving in extremely adverse weather conditions or in areas where ambient temperatures are either extremely low or extremely high
F: Driving in high humidity or mountainous areas
G: Driving in areas which are high in salt or other corrosive materials
H: Driving on rough and/or muddy roads or in the desert
I: Driving with frequent use of brakes
J: Frequent driving in water

Maintenance Schedule for Normal Driving Conditions
If you primarily operate your vehicle under conditions other than those listed above, please follow the "Maintenance Under Normal Driving Conditions" column of the maintenance section of your Customer Information Booklet.

Unscheduled maintenance
Besides the scheduled maintenance items for which there are fixed maintenance intervals, there are other items that should operate satisfactorily without periodic maintenance. However, if a malfunction of these items does occur, it could adversely affect the engine or vehicle's performance. These items should be inspected or adjusted if necessary, if a symptom of a malfunction is observed or suspected.

During normal day-to-day operation of the vehicle, general maintenance should be performed regularly by the vehicle owner as prescribed in the Maintenance and Do-it-yourself section of the Owner's Manual.

If the vehicle owner detects any unusual sounds, vibrations or smells, the cause should be checked or have a Nissan dealer do it promptly. In addition, the vehicle owner should notify a Nissan dealer if you think that repairs may be required.

MAINTENANCE PRECAUTIONS
When performing any inspection or maintenance work on a vehicle, always take care to prevent serious accidental injury to yourself or damage to the vehicle. It is strongly recommended that the precautions outlined in the Maintenance and Do-it-yourself section of the Owner's manual should be closely observed.

An example of the typical unscheduled inspection items would include but not necessarily be limited to the following:

• Adjust intake and exhaust valve clearances
• Check and adjust drive belts
• Check cooling system and ratio of Long Life engine coolant
• Check fuel lines

Under normal driving conditions, the air cleaner filter should be replaced at the designated interval. However, driving the vehicle in dusty areas will cause rapid clogging of the element. Consequently, the element may have to be replaced more frequently.

• Check pre-air cleaner (where fitted)
• Check engine oil and oil filter

Under normal driving conditions, the engine oil and oil filter should be replaced in accordance with the maintenance schedule. However, under severe driving conditions, they may have to be replaced more frequently.

• Replace fuel filter (where fitted)

Under normal driving conditions, the filter should be changed at the designated interval. However, under severe driving conditions, it may have to be replaced more frequently.

• Replace spark plugs
• Check ignition wires
• Check EVAP vapour lines
• Check heated oxygen sensor (Exhaust gas sensor)
• Replace timing belt (where fitted)
• Check positive crankcase ventilation (PCV) system
• Check PCV valve for proper operation.
