BALANCING WHEELS (BONDING WEIGHT TYPE)
Preparation Before Adjustment
Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
 Be careful not to scratch th e road wheel during removal.
 After removing double-faced adhesive tape, wi pe clean traces of releasing agent from the road
wheel.
Wheel Balance Adjustment
If a tire balance machine has adhesion balance weight m ode settings and drive-in weight mode setting, select
and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer unbalance value by 5/3 to determine balance weight t hat should be used. Select the outer balance weight
with a value closest to the calculated value above and in stall to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:
 Never install the inner balance weight be fore installing the outer balance weight.
 Before installing the balance weight, always to clean the mating surface of the road wheel.

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 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-

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, "

"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.

CAUTION:
 After any collision, inspect all seat belt assembli es, including retractors and other attached hard-
wares (I.e. anchor bolt, guide ra il set). Nissan recommends to replace all seat belt assemblies in use
during a collision, unless not damaged and pr operly operating after minor collision.
Also inspect seat belt assemblies not in use during a collision, and replace if damaged or improperly
operating.
Seat belt pre-tensioner should be replaced even if th e seat belts are not in use during a frontal colli-
sion where the driver and passenger air bags are deployed.
 If any component of seat belt assembl y is questionable, do not repair.
Replace as seat belt assembly.
 If webbing is cut, frayed, or damaged, replace belt assembly.
 Never oil tongue and buckle.
 Use a genuine NISSAN seat belt assembly.
For details, refer to SB-4, "
SEAT BELT RETRACTOR : Inspection", SB-10, "SEAT BELT RETRACTOR :
Inspection", SB-17, "SEAT BELT RETRACTOR : Inspection" in SB section.
 Check anchors for loose mounting
