Tire RotationNLS00088
After rotation the tires, adjust the tire pressure.
Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:
Do not include the T-type spare tire when rotating the tires.
When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
Checking Brake Fluid Level and LeaksNLS00089
If fluid level is extremely low, check brake system for leaks.
Checking Brake Lines and CablesNLS0008A
Check brake fluid lines and parking brake cables for improper
attachment, leaks, chafing, abrasions, deterioration, etc.
Changing Brake FluidNLS0008B
1. Drain brake fluid from each bleed valve.
2. Refill until new brake fluid comes out from each bleed valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid.
Refer to BR-11, "
Bleeding Brake System" .
Refill with recommended Genuine Nissan Super Heavy Duty
Brake Fluid or equivalent DOT 3 (US FMVSS No. 116).
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Never reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas.Tightening torque of wheel nut

drive gear and drive pinion as a set.
Bearing
If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing
is observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear
If any cracks or damage on the surface of the tooth is found, replace.
If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer
If it is chipped (by friction), damaged, or unusually worn, replace.
Oil seal
Whenever disassembled, replace.

them.
Differential case
If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange
If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the

PRE-CRASH SEAT BELTPFP:98845
Component Parts and Harness Connector LocationNHS0007X
System DescriptionNHS0007Y
Pre-crash seat belt system is adapted to front seat belts RH/LH.
When the pre-crash seat belt control unit judges the emergency braking operation, it gives the sense of
security by the motor built into the pre-crash seat belt retracting the shoulder belt and suppressing the
crew's posture change. Also, it eases the damage of the collision.

CAN Communication System DescriptionNHS0007Z
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNHS00080
Refer to LAN-34, "CAN Communication Unit" .
