GENERAL MAINTENANCE

MA-5

< ON-VEHICLE MAINTENANCE >

UNDER THE HOOD AND VEHICLE

The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).

Seat belts

Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage.

MA-33

Accelerator pedal

Check the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal.

—

Brakes

Check that the brake does not pull the vehicle to one side when applied.

—

Brake pedal and
booster

Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to
keep the floor mats away from the pedal.

BR-7

BR-14

Clutch pedal

Make sure the pedal operates smoothly and check that it has the proper free
play.

CL-5

Parking brake

Check that the pedal has the proper travel and make sure that the vehicle is
held securely on a fairly steep hill when only the parking brake is applied.

PB-3

(PEDAL TYPE)

PB-4

(LEVER TYPE)

Automatic transmis-
sion "Park" mecha-
nism

Check that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the
selector lever in the P (Park) position without applying any brakes.

Windshield washer
fluid

Check that there is adequate fluid in the tank.

—

Engine coolant level

Check the coolant level when the engine is cold.

CO-8

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, de-
terioration or loose connections.

—

Brake and clutch fluid
level

Make sure that the brake and clutch fluid levels are between the “MAX” and
“MIN” lines on the reservoir.

MA-29
MA-23

Battery

Check the fluid level in each cell. It should be between the “MAX” and “MIN”
lines. Vehicles operated in high temperatures or under severe conditions re-
quire frequent checks of the battery fluid level.

PG-3

Engine drive belts

Make sure that no belt is frayed, worn, cracked or oily.

MA-12

Engine oil level

Check the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine.

LU-6

Power steering fluid
level and lines

Check the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.

MA-31

Exhaust system

Make sure there are no loose supports, cracks or holes. If the sound of the ex-
haust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it.

MA-20

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 sub-
stances, otherwise rust will 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
can easily accumulate.

—

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 gasoline fumes are evident, check for
the cause and correct it immediately.

Introduction of Periodic Maintenance

INFOID:0000000001679214

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.

Schedule 1

INFOID:0000000001679215

EMISSION CONTROL SYSTEM

Abbreviations: R = Replace.

I = Inspect. Correct or replace if necessary.

[ ]: At the mileage interval only

Schedule 1

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.

• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi

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.

NOTE:

(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found

damaged or if the auto belt tensioner reading reaches the maximum limit.

(2) If operating mainly in dusty conditions, more frequent maintenance may be required.

(3) Maintenance-free item. For service procedures, refer to FL section.

(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.

(5) Periodic maintenance is not required. However, if valve noise increases, inspect valve clearance.

* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.

PERIODIC MAINTENANCE

NOTE:

(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fluid (A/T, trans-
fer)/oil at every 30,000 miles (48,000 km) or 24 months. Using automatic transmission fluid other than Genuine NISSAN Matic J
ATF will cause deterioration in driveability and automatic transmission durability, and may damage the automatic transmis-
sion, which is not covered by the INFINITI new vehicle limited warranty.

(2) Refer to “Tire rotation” under the “General maintenance” heading earlier in this section.

(3) Inspect the clearance between the brake pedal and the switches.
