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.

CHASSIS MAINTENANCE
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.

 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.
3. Check that there is no foreign material in t he reservoir tank, and refill with new brake fluid.
CAUTION:
 Never reuse drained brake fluid.
 Never allow oils other than brake fl uid to enter the reservoir tank.
4. Turn the ignition switch ON. NOTE:
The motor is activated and automatically stops.
5. Turn the ignition switch OFF.
6. 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.
7. Repeat steps 4 to 6 for 5 times.
8. Turn the ignition switch ON to check that the time between motor activation and automatic stop is less
than 18 seconds. If the time is 18 seconds or more, repeat from Step 4 to 8.
FRONT 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.
 Never operate the brake pedal excessively during the work procedure.

→ 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

3. Check that there is no foreign material in t he reservoir tank, and refill with new brake fluid.
CAUTION:
 Never reuse drained brake fluid.
 Never allow oils other than brake fl uid 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. 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.

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 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.
