RotationNLS00088

Follow the maintenance schedule for tire rotation service inter-
vals. Refer to MA-4, "
GENERAL MAINTENANCE" .

Do not include the spare tire when rotating the tires.
CAUTION:

When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.

Be careful not to tighten wheel nut at torque exceeding the
criteria for preventing strain of disc rotor.

Use NISSAN genuine wheel nuts for aluminum wheels.
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-10, "
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

PEDAL STROKE

Operate parking brake pedal with a force of 196 N (20 kg, 44 lb), make sure pedal stroke is within the
specified number of notches. (Check it by listening and counting ratchet clicks.)
INSPECT COMPONENTS

Make sure that the mounting conditions (looseness, backlash, etc.) of each component are normal.

Check the following:
–Device assembly for bend, damage and cracks. Replace if there are.
–Cables and equalizer for wear and damage. Replace if there are.
–Parking brake switch. Replace if it does not work correctly.
ADJUSTMENT

To perform adjustment operations, remove rear tires from vehicle with power tool.
1. Insert a deep socket wrench onto adjusting nut. Rotate adjusting
nut to fully loosen cable, and then release parking brake pedal.
2. Secure disc rotor to hub using wheel nut so as not to tilt disc
rotor.
3. Remove adjuster hole plug installed on the disc rotor. Turn the
adjuster in direction “A” using a flat-bladed screwdriver as
shown, until disc rotor is locked. Turn the adjuster in the oppo-
site direction by 5 or 6 notches after locking.
4. Rotate disc rotor to make sure that there is no drag. Install the
adjuster hole plug.
5. Adjust parking brake cable with the following procedure.
a. Operate parking brake pedal 10 or more times with the force of
full stroke.
b. Rotate adjusting nut to adjust parking brake pedal stroke using a
deep socket wrench.
CAUTION:
Do not reuse adjusting nut after removing it.
c. Operate parking brake pedal with a force of 196 N (20 kg, 44 lb), make sure the pedal stroke is within the
specified number of notches. (Check it by listening and counting ratchet clicks.)

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NGS000CZ
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectNGS000D0
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.

Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.

PRECAUTIONS
Revision: 2007 April2007 M35/M45
Precautions for Steering SystemNGS000D1

In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehi-
cle condition, and then check wheel alignment.

Observe the following precautions when disassembling.
–Before disassembly, thoroughly clean the outside of the unit.
–Disassembly should be done in a clean work area. It is important to prevent the internal parts from becom-
ing contaminated by dirt or other foreign matter.
–For easier and proper assembly, place disassembled parts in order on a parts rack.
–Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere
with their operation.
–Do not reuse non-reusable parts.
–Before assembling, apply the specified grease to the directed parts.
