CAUTION:
A steel plate using ultra high strength steel plate is below welding with strength falling by adding heat,
and not doing a limit patch.
Front pillar butt joint can be determined anywhere within shaded
area as shown in the figure. The best location for the butt joint is
at position A due to the construction of the vehicle. Refer to the
front pillar section.
Determine cutting position and record distance from the locating
indent. Use this distance when cutting the service part. Cut outer
front pillar over 60 mm above inner front pillar cut position.
Prepare a cutting jig to make outer pillar easier to cut. Also, this
will permit service part to be accurately cut at joint position.
An example of cutting operation using a cutting jig is as follows.
1. Mark cutting lines.
A: Cut position of outer pillar
B: Cut position of inner pillar
2. Align cutting line with notch on jig. Clamp jig to pillar.
3. Cut outer pillar along groove of jig. (At position A)
4. Remove jig and cut remaining portions.
5. Cut inner pillar at position B in same manner.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS000ON
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 for Procedures without Cowl Top CoverNFS000OO
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS000OP
Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
Recommended fluid is brake fluid “DOT 3”.
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.
Use clean brake fluid, to clean or wash all parts of master cylinder and disc brake caliper, etc.
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
Use flare nut torque wrench when installing brake tube.
When installing brake tube and hose, be sure to check torque.
Before working, turn ignition switch OFF and disconnect con-
nectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.
Burnish the brake contact surfaces after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low
mileage. Refer to BR-28, "
BRAKE BURNISHING PROCE-
DURE" (front disc brake), BR-34, "BRAKE BURNISHING PRO-
CEDURE" (rear disc brake).
WAR NING :
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.

BRAKE BOOSTER
Revision: 2006 January2006 M35/M45
BRAKE BOOSTERPFP:47200
On-Board Inspection and ServiceNFS000P6
OPERATION CHECK
With engine stopped, change vacuum to atmospheric pressure by
depressing brake pedal several times. Then with brake pedal fully
depressed, start engine and when vacuum pressure reaches the
standard, make sure that clearance between brake pedal and floor
panel decreases.
AIR TIGHT CHECK
Run engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change vacuum to atmospheric pressure. Make sure that dis-
tance at intervals of 5 seconds between brake pedal and floor
panel gradually increases.
Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change after
holding pedal down for 30 seconds.

FRONT DISC BRAKE
Revision: 2006 January2006 M35/M45
It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, hang cylinder body with a wire so as not to stretch
brake hose.
Do not damage piston boot.
If any shim is subject to serious corrosion, replace it with a new one.
Always replace shim and shim cover as a set when replacing brake pads.
Keep rotor free from brake fluid.
Burnish the brake pads and disc rotor mutually contacting surfaces, after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low mileage. Refer to BR-28, "
BRAKE
BURNISHING PROCEDURE" .
Removal and Installation of Brake PadNFS000PD
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers,
shims, and shim cover from torque member.
CAUTION:
When removing the pad retainer from the torque member,
lift it in the direction indicated by the arrow in the figure so
that it does not deform.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or equivalent to between shim cover and shim. Install shim, shim
cover, to pad.
2. Apply PBC (Poly Butyl Cuprysil) grease or equivalent to
between pad retainer and pad. Install pad retainers and pads to
torque member.
CAUTION:
Securely assemble pad retainers so that they are not
being lifted up from torque member.
Both inner and outer pads have a pad return system on
the pad retainer. Install pad return lever securely to pad
wear sensor.
3. Install cylinder body to torque member.
CAUTION:
In the case of replacing a pad with new one, check a brake fluid level in the reservoir tank because
brake fluid returns to master cylinder reservoir tank when pressing piston in.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press piston.
4. Install lower sliding pin bolt, and tighten it to the specified torque. Refer to BR-23, "
Components" .
5. Check front disc brake for drag.
6. Install tires to vehicle.

REAR DISC BRAKE
Revision: 2006 January2006 M35/M45
WAR NING :
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air borne
particles or other materials.
CAUTION:
While removing cylinder body, do not depress brake pedal because piston will pop out.
It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, hang cylinder body with a wire so as not to stretch
brake hose.
Do not damage piston boot.
If any shim is subject to serious corrosion, replace it with a new one.
Always replace shim and shim covers as a set when replacing brake pads.
Keep rotor free from brake fluid.
Burnish the brake pads and disc rotor mutually contacting surfaces after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low mileage. Refer to BR-34, "
BRAKE
BURNISHING PROCEDURE" .
Removal and Installation of Brake PadNFS000PI
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers, shims, and shim cover from torque mem-
ber.
CAUTION:
Deform pad retainer when removing pad retainer from torque member.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or equivalent to between shim cover and shim. Install inner shim,
inner shim cover to inner pad, and outer shim, outer shim cover to outer pad.
2. Install pad retainers and pads to torque member.
3. Press in piston until pads can be installed, and then install cylin-
der body to torque member.
CAUTION:
In the case of replacing a pad with new one, check a brake
fluid level in the reservoir tank because brake fluid returns
to master cylinder reservoir tank when pressing piston in.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily
press piston.
4. Install upper sliding pin bolt and tighten to the specified torque.
Refer to BR-29, "
Components" .
