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 294
N (30 kg, 66 lb).
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.)
d. Make sure that there is no drag on rear brake with parking brake pedal completely released. Pedal stroke : 3 - 4 notches

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.
WAR NING :
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:
Before removing and installing any control units, first turn the push-button ignition switch to the LOCK
position, then disconnect both battery cables.
After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, 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. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-II.

PRECAUTIONS
Revision: 2006 January2006 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.
