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 beltsCheck 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-39, "SEAT BELT,
BUCKLES, RETRAC-
TORS, ANCHORS AND
ADJUSTERS : Checking
Seat Belts, Buckles, Re-
tractors, Anchors and
Adjusters"
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. ACC-6, "Accelerator
Control"
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-15, "
Inspection and
Adjustment", BR-10, "In-
spection"
Parking brake
Check that the lever or 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 ap-
plied. PB-5, "On-Vehicle Ser-
vice"
Automatic transmis-
sion “Park” mecha-
nismCheck 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 se-
lector lever in the P position without applying the brakes.

Engine coolant level Check the coolant level when the engine is cold. CO-10, "
Inspection"
Radiator and hosesCheck 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 fluid level Make sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir. MA-34, "
BRAKE FLUID
LEVEL AND LEAKS : On

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 require fre-
quent checks of the battery fluid level. —
Engine drive belt Make sure that no belt is frayed, worn, cracked or oily. MA-15, "
DRIVE BELTS :

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-26, "EXHAUST SYS-

PERIODIC MAINTENANCE
Introduction of Periodic MaintenanceINFOID:0000000005145934
Two different maintenance schedules are provi
ded, 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 or ti me intervals, whichever comes first.
Maintenance for Off-road Driving (4WD only)INFOID:0000000005145935
Whenever you drive off-road through sand, mud, or wa ter; more frequent maintenance may be required for the
following items:
Brake pads and rotors
Brake lines and hoses
Rear final drive oil, transmission fluid, and transfer fluid
Steering linkage
Drive shafts
Engine air cleaner filter
In-cabin microfilters

Schedule 1Follow Periodic Maintenance Schedule 1 if the driving habits frequently includes
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 re-
maining 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.

PERIODIC MAINTENANCE
(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, go to the 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 NISSAN 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.

(1) If towing a trailer, or using a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil at every
30,000 miles
(48,000 km) or 24 months. Using automatic transmission fluid other than Ge nuine NISSAN Matic S ATF or Matic J ATF will cause
deterioration in drive ability and automatic transmission durability, and may damage the automatic transmission, 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.

RECOMMENDED FLUIDS AND LUBRICANTS
Engine Oil Recommendation
INFOID:0000000005145939
NISSAN recommends the use of an energy conserving oil in order to
improve fuel economy. Select only engine oils that meet the Ameri-
can Petroleum Institute (API) certification and International Lubricant
Standardization and Approval Committee (ILSAC) certification and
SAE viscosity standard (2). These oils have the API certification
mark (1) on the front of the container. Oils which do not have the
specified quality label should not be used as they could cause
engine damage.
ANTI-FREEZE COOLANT MIXTURE RATIO
The engine cooling system is filled at the factory with a high-quality, long life, year-round, anti-freeze coolant
solution. The anti-freeze solution contains rust and co rrosion inhibitors. Therefore, additional cooling system
additives are not necessary.
CAUTION:
• When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Anti-freeze cool-
ant or equivalent with the proper mixture ratio of 50% anti-freeze and 50% demineralized water or
distilled water.
• Other types of coolant solution s may damage your cooling system.

• Pull negative-pressure valve to open it and make sure that it closes
completely when released.
• Make sure that there is no dirt or damage on the valve seat of radi-

• Make sure that there are no unusualness in the opening and clos- ing conditions of negative-pressure valve.
ENGINE COOLANT : Chang ing Engine CoolantINFOID:0000000005403134
WARNING:
• To avoid being scalded, never change the coolant when the engine is hot.
• Wrap a thick cloth around the cap to carefully remo ve the cap. First, turn the cap a quarter of a turn
to release any built-up pressure, then push down and turn the cap all the way to remove it.
DRAINING ENGINE COOLANT
1. Turn ignition switch ON and set temperature control lever all the way to HOT position or the highest tem-
perature position. Wait 10 seconds and turn ignition switch OFF.
2. Remove the engine front undercover using power tool.
3. Open the radiator drain plug at the bottom of the radiator, and remove the radiator filler cap. This is the only step required
when partially draining the cooling system (radiator only).
CAUTION:
Do not to allow the coolant to contact the drive belts.
4. When draining all of the coolant in the system for engine removal or repair, it is necessary to drain the cylinder block.
Remove the RH cylinder block drain plug to drain the right bank
and the oil cooler hose to drain the left bank as shown.
