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).
Seats Check seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every po-
sition. Check that the head restrains move up and down smoothly and that the
locks (if equipped) hold securely in all latched positions. Check that the latches
lock securely for folding-down rear seatbacks. —
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-34
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-15
Parking brake
Check that the lever or pedal has the proper travel and make sure that the ve-
hicle is held securely on a fairly steep hill when only the parking brake is ap-
plied. PB-3
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
selector lever in the P (Park) position without applying any brakes.

Item
Reference page
Item Reference page
Windshield washer
fluid Check that there is adequate fluid in the tank. —
Engine coolant level Check the coolant level when the engine is cold. MA-12
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. MA-16
Brake fluid levels
Make sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir(s). MA-28
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-159
Engine drive belts
Make sure that no belt is frayed, worn, cracked or oily. MA-12
Engine oil levelCheck the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine. LU-7
Power steering fluid
level and linesCheck the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.
MA-32
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-21
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. —

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 i
f 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) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000
km) or 60 months. Use only Genu ine NISSAN Long Life Antifreeze/Coo lant (blue) or equivalent with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water will reduce the life
expectancy of the factory-fill coolant.
(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 perfo rm
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.

a. Indicated unbalance value
× 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) ⇒ 37.5 g (1.32 oz) bal-
ance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
36.2 ⇒ 35 g (1.23 oz)
36.3 ⇒ 37.5 g (1.32 oz)
b. Installed balance weight in the position.  When installing balance weight (1) to road wheels, set it into
the grooved area (A) on the inner wall of the road wheel as
shown in the figure so that the balance weight center (B) is
aligned with the tire balance machine indication position
(angle) (C).
CAUTION:
 Always use genuine NISSAN ad hesion balance weights.
 Balance weights are non-re usable; always replace with
new ones.
 Never install more than four sheets of balance weight.
c. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other as shown in
the figure.
CAUTION:
Never install one balance weight sheet on top of another.
3. Start the tire balance machine again.
4. Install drive-in balance weight on inner side of road wheel in the tire balance machine indication position (angle).
CAUTION:
Never install more than two balance weight.
5. Start the tire balance machine. Check that the inner and outer residual unbalance value is within the allowable unbalance
value.
CAUTION:
If either residual unbalan ce value exceeds limit, repeat installation procedures.

BRAKE FLUID LEVEL AND LEAKS : Inspection
INFOID:0000000006220939
 Check that the fluid level in the sub tank is within the specified range (MAX – MIN lines).
CAUTION:
Turn OFF the ignition switch an d depress the brake pedal 20 times or more to check brake fluid level.
NOTE:
Since brake fluid is in the accumulator in pressurized condition, the reservoir tank brake fluid level should be
lower than the MAX line.
 Visually check for any brake fluid leakage around the reservoir tank.
 Check the brake system for any leakage if the fl uid level is extremely low (lower than MIN).
 Check the brake system for fluid leakage if the warn ing lamp remains illuminated even after the parking
brake is released.
 Check the sub tank for the mixing of foreign ma tter (e.g. dust) and oils other than brake fluid.
BRAKE LINES AND CABLES
BRAKE LINES AND CABLES : InspectionINFOID:0000000006220940
1. Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged
parts.
2. Depress the brake pedal with a force of 490 N (50 kg, 110lb) and hold down the pedal for approx. 5 seconds with the engine run-
ning. Check for any fluid leakage.
CAUTION:
Retighten the applicable conn ection to the specified torque
and repair any abnormal (damag ed, worn or deformed) part
if any brake fluid leakage is present).
BRAKE FLUID
BRAKE FLUID : Bleeding Brake SystemINFOID:0000000006220941
CAUTION:
 Bleed air in the following order: motor/accumulator assembly → front right brake → front left brake
→ rear left brake → and rear right brake.
 The VDC warning lamp, ABS warning lamp and br ake warning lamp turn ON and DTC “C118E” may
be detected in self-diagnosis r esult for “ABS” with CONSULT-II I when the brake pedal is excessively
operated, such as air bleeding. Thi s is not a system malfunction becau se this occurs due to the tem-
porary decrease in accumulator fl uid pressure. The system returns to normal condition when the
accumulator fluid pressure reaches the specified pressu re with the ignition switch ON and the VDC
warning lamp, ABS warning lamp, and brake warnin g lamp turn OFF. After these steps, erase self-
diagnosis results for “ABS” with CONSULT-III.
- DTC other than “C118E” is detected: Refer to BRC-51, "
DTC Index".
NOTE:
When the ignition switch is ON, the brake warning la mp may turns ON even when the parking brake pedal is
released with the brake fluid within the specified level. This indicates the decrease in accumulator fluid pres-
sure.
MOTOR/ACCUMULATOR ASSEMBLY
CAUTION:
 If the brake fluid adheres to the brake caliper assembly and disc rotor, quickly wipe it off.
 Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with wate r if it gets on a painted surface.
 Never operate the brake pedal with the reservoir cap removed. Failure to do this may cause the scat-
tering of brake fluid.
 Never operate the brake pedal excessively during the work procedure.
 Monitor the fluid level in the reservoir tank while performing the air bleeding.

4. Turn the ignition switch ON.
5. Connect a vinyl tube to the bleed valve.
6. Depress the brake pedal and loosen the bleeder valve.
7. Repeat steps 1 to 6 until all of the air is out of the brake line and tighten the air bleeder to the specified
torque with the brake pedal depressed. Refer to BR-36, "
BRAKE CALIPER ASSEMBLY : Exploded View".
8. Check that no drag feel is present for the front disc brake. Refer to BR-39, "
BRAKE CALIPER ASSEMBLY
: Inspection".
9. Check each item of brake pedal. Adjust it if t he measurement value is not the standard. Refer to BR-7,
"Inspection and Adjustment".
REAR BRAKE
CAUTION:
 If the brake fluid adheres to the brake caliper assembly and disc rotor, quickly wipe it off.
 Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with wate r if it gets on a painted surface.
 Never operate the brake pedal with the reservoir cap removed. Failure to do this may cause the scat-
tering of brake fluid.

CHASSIS MAINTENANCE
 Never operate the brake pedal excessively during the work procedure.
 Monitor the fluid level in the reservoir tank while performing the air bleeding.
 Bleed air in the following order: motor/accumulator assembly → front right brake → front left brake
→ rear left brake → and rear right brake.
1. Turn the ignition switch OFF.
2. Depress the brake pedal 20 times or more. NOTE:
The pressure loss in the accumulator results in a large brake pedal stroke. In addition to this, the brake
pedal depression becomes lighter in initial stage.
3. Check that there is no foreign material in the reservoir tank, and refill with new brake fluid. CAUTION:
 Never reuse drained brake fluid.
 Never allow oils other than brake fluid to enter the reservoir tank.
4. Turn the ignition switch ON.
5. Connect a vinyl tube to the bleed valve.
6. Depress the brake pedal and loosen the bleeder valve.
7. Depress and hold the brake pedal depression to dischar ge 100 cc of brake fluid before tightening the air
bleeder to the specified torque. Refer to BR-42, "
BRAKE CALIPER ASSEMBLY : Exploded View".
NOTE:
Since brake fluid is conveyed by the motor, the brake pedal is not necessarily depressed.
8. Release the brake pedal.
9. Repeat steps 1 to 8 until all of the air is out of the brake line and tighten the air bleeder to the specified
torque with the brake pedal depressed. Refer to BR-42, "
BRAKE CALIPER ASSEMBLY : Exploded View".
10. Check that no drag feel is present for the rear disc brake. Refer to BR-45, "
BRAKE CALIPER ASSEMBLY
: Inspection".
11. Check each item of brake pedal. Adjust it if t he measurement value is not the standard. Refer to BR-7,
"Inspection and Adjustment".
BRAKE FLUID LEVEL ADJUSTMENT AFTER AIR BLEEDING
1. Turn the ignition switch OFF.
2. Depress the brake pedal 20 times or more.
NOTE:
The pressure loss in the accumulator results in a large brake pedal stroke. In addition to this, the brake
pedal depression becomes lighter in initial stage.
3. Adjust brake fluid level to the reservoir tank MAX line. CAUTION:
Never adjust with the ignition switch ON.
4. Turn the ignition switch ON.
5. Check that the reservoir tank brake fluid level is 4 − 12 mm (0.16
− 0.47 in) lower than the MAX line.
NOTE:
Since brake fluid is in the accumulator in pressurized condition,
the reservoir tank brake fluid level should be lower than the MAX
line.
