GENERAL MAINTENANCE

Explanation of General Maintenance INFOID:0000000002957330

General maintenance includes those items which should be checked during the normal day-to-day operation of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform checks and inspections themselves or they can have their INFINITI dealers do them.

OUTSIDE THE VEHICLE

The maintenance items listed here should be performed from time to time, unless otherwise specified.

Item Reference page Tires Check the pressure with a gauge often and always prior to long distance trips.

Adjust the pressure in all tires, including the spare, to the pressure specified. Check carefully for damage, cuts or excessive wear.

Wheel nuts When checking the tires, make sure no nuts are missing, and check for any

loose nuts. Tighten if necessary.

Tire rotation Tires should be rotated every 12,000 km (7,500 miles). MA-33 Tire Pressure Moni-

Replace the TPMS transmitter g rommet seal, valve co re and cap when the tire s are replaced due to wear or age.

If the vehicle pulls 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.

Clean the windshield on a regular basis. Chec k the windshield at least every six months for cracks or other damage. Repair as necessary.

Check for cracks or wear if they do not wipe properly. — Check that all doors and the en gine hood operat e properl y as well as the t runk

lid. Also make sure that all latches lock securely. Lubricate 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.

other lamps are all operating properly and installed securely. Also check headlamp aim. Clean the headlamps on a regular basis.

PERIODIC MAINTENANCE

Introduction of Periodic Maintenance INFOID:0000000002957331

Two different maintenance schedules are provided, and should be used, depending upon the conditions in which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic

maintenance at the same mileage/time intervals.

Follow Periodic Maintenance Schedule 1 if the driving habits frequently include one or more of the following driving conditions:

• Repeated short trips of less than 5 miles (8 km).

• Repeated short trips of less than 10 miles (16 km) with outside temperatures remaining below freezing.

Schedule 1

Schedule 2

• Operating in hot weather in stop-and-go “rush hour” traffic.

• Extensive idling and/or low sp eed driving for long dist ances, such as police, ta xi or door-to-door delivery use.

• Driving in dusty conditions.

• Driving on rough, muddy, or salt spread roads.

• Towing a trailer, using a camper or a car-top carrier.

Follow Periodic Maintenance Schedule 2 if none of driving conditions shown in Schedule 1 apply to the driving ha bits.

Anti-Freeze Coolant Mixture Ratio INFOID:0000000002957336

The engine cooling system is filled at the factory with a high-quality, year-round, anti-freeze coolant solution. The anti-freeze solution contains rust and corrosion inhibitors. Therefore, additional cooling system additives are not necessary.

CAUTION:

When adding or replacing coolant, be sure to use only genuine NISSAN Long Life Antifreeze/ Coolant or equivalent with the proper mixture ratio of 50% anti-freeze and 50% demineralized water/distilled water. Other types of coolant solutions may damage your cooling system.

ENGINE MAINTENANCE (VQ35DE ENGINE)

Checking Drive Belts INFOID:0000000002957337

WARNING:

Be sure to perform when engine is stopped.

1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.

2. Inspect drive belt deflection or tension at a point on belt midway between pulleys.

1 : Power steering oil pump 2 : Alternator 3 : Idler pulley 4 : Crankshaft pulley 5: A/C compressor

• Inspection should be done only when engine is cold, or over

30 minutes after engine is stopped.

• Measure the belt tension with belt tension gauge (Commercial

service tool: BT3373-F or equivalent) (A) at points marked shown in the figure.

• When measuring the deflection, apply 98 N (10 kg, 22 lb) at

the marked point.

• Adjust if the belt deflection exceeds the limit or if the belt ten-

sion is not within specifications.

CAUTION:

• When checking the belt deflection or the tension immedi-

ately after installation, first adjust it to the specified value. Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflection between pulleys.

• Tighten idler pulley lock nut by hand and measure the deflection or the tension without loose-

ness.

< SERVICE INFORMATION >

• When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insufficient adaptability with pulley grooves.

• When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjustment”.

• When checking belt deflection or tension immediately after installation, first adjust it to the specified value. Then, after turning crankshaf t two turns or more, re-adjust to the specified value to avoid variation in deflection between pulleys.

• When installing belt, check that it is correctly engaged with pulley grooves.

• Keep engine oil, working fluid and engine coolant away from belt and pulley grooves.

• Never twist or bend belt excessively.

ALTERNATOR AND POWER STEERING OIL PUMP BELT

1. Remove front engine undercover with power tool.

2. Loosen idler pulley lock nut (A) and adjust tension by turning

adjusting bolt (B).

• For the specified belt tension, refer to MA-11, "
