Precaution for Supplemental  Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER" INFOID:0000000004803451
The  Supplemental  Restraint  System  such  as  “A IR  BAG”  and  “SEAT  BELT  PRE-TENSIONER”,  used  along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether 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 inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS can lead to personal
injury  caused  by  unintentional  act ivation  of  the  system.  For  removal  of  Spiral  Cable  and  Air  Bag
Module, see the SRS section.
• Do  not  use  electrical  test  equipm ent  on  any  circuit  related  to  the  SRS  unless  instructed  to  in  this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer.  Heavy  vibration  could  activate  the  sensor( s)  and  deploy  the  air  bag(s),  possibly  causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precaution Necessary for Steering Wh eel Rotation After Battery Disconnect
INFOID:0000000004305289
NOTE:
• This  Procedure  is  applied  only  to  models  with  Intell igent  Key  system  and  NVIS/IVIS  (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
• Remove  and  install  all  control  units  after  disconnecti ng  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  pow er  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 al l control units using CONSULT-III.

a. Install seal rings to bearing retainer, and set forward clutch drum.
b. Apply compressed air into oil hole of bearing retainer at the loca- tion as shown.
c. Check to see that retaining plate moves to snap ring.
d. If retaining plate does not contact snap ring: • D-ring might be damaged.
• Seal lip might be damaged.
• Fluid might be leaking past piston check ball.
3. Remove  snap  ring  for  forward  clutch  from  forward  clutch  drum using a flat-bladed screwdriver.
4. Remove  retaining  plate,  drive  plates,  driven  plates  and  dish plate for forward clutch.
5. Remove  snap  ring  for  overrun  clutch  from  forward  clutch  drum using a flat-bladed screwdriver.
6. Remove  retaining  plate,  drive  plates,  driven  plates  and  dish plate for overrun clutch. SAT202D

FRONT DISC BRAKE
2. Remove  sliding  pin  bolts  and  remove  cylinder  body  from  the torque  member.  Remove  pads,  shims,  pad  return  spring
(AD22VK) and pad retainers from torque member as necessary.
CAUTION:
When  removing  pad  retainer  fr om  torque  member,  lift  the
pad  retainer  in  the  direction   shown  by  arrow,  so  as  not  to
deform it.
3. Remove sliding pins and sliding pin boots from torque member.
4. Place  a  wooden  block  as  shown,  and  blow  air  from  union  bolt mounting hole to remove piston and piston boot.
CAUTION:
Do not get fingers caught in the piston.
5. Remove piston seal with a flat-bladed screwdriver. CAUTION:
Be careful not to damage the inner wall of cylinder.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of cylinder for corrosion, w ear, and damage. Replace cylinder body as necessary.
CAUTION:
Clean cylinder body using new brake fluid. Never  use mineral oils such as gasoline or kerosene.
Torque Member
Check for wear, cracks, and damage. R eplace torque member as necessary.
Piston
Check piston surface for corrosion, wear, and damage. Replace piston as necessary.
CAUTION:
The piston sliding surface is plated . Do not polish with sandpaper.
Sliding Pin, Sliding Pin Bolt, and Sliding Pin Boot
Check  sliding  pins,  sliding  pin  bolts  and  sliding  pin  boots  for  wear,  damage,  and  cracks.  Replace  applicable
part as necessary.
DISC ROTOR INSPECTION 
Visual Inspection
Check surfaces of disc rotor for uneven wear, cr acks, and serious damage. Replace as necessary.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit  or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer.  Heavy  vibration  could  activate  the  sensor( s)  and  deploy  the  air  bag(s),  possibly  causing
serious injury.
• When using air or electric power tools or hammers ,  always  switch  the  Ignition  OFF,  disconnect  the
battery, and wait at least 3 minu tes before performing any service.
Precaution for Brake System INFOID:0000000004307251
CAUTION:
• Refer to  MA-14  for recommended brake fluid.
• Never reuse drained brake fluid.
• Be  careful  not  to  splash  brake  fluid  on  painted   areas;  it  may  cause  paint  damage.  If  brake  fluid  is
splashed on painted areas, wash  it away with water immediately. 
• To clean or wash all parts of master cylin der and disc brake caliper, use clean brake fluid.
• Never use mineral oils such as gasoline or kerosene.  They will ruin rubber parts of the hydraulic sys-
tem. 
• Use  flare  nut  wrench  when  re moving  and  installing  brake
tube. 
• If  a  brake  fluid  leak  is  found,  the  part  must  be  disassembled
without  fail.  Then  it  has  to  be  replaced  with  a  new  one  if  a
defect exists. 
• Turn the ignition switch OFF an d remove the connector of the
ABS actuator and electric unit (c ontrol unit) or the battery ter-
minal before performing the work. 
• Always torque brake lines when installing.
• Burnish the brake contact surf aces after refinishing or replac-
ing  rotors,  after  replacing  pads,  or  if  a  soft  pedal  occurs  at
very  low  mileage.  Refer  to   BR-32,  " Brake  Burnishing  Proce-
