PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS00001
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 for Battery ServiceNFS00002
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Precautions for Procedures without Cowl Top CoverNFS000HT
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS00003

Recommended fluid is brake fluid “DOT 3”. Refer to MA-11, "Fluids and Lubricants" .

Do not reuse drained brake fluid.

Do not let brake fluid come in contact with painted surfaces on the body. This might damage the paint, so
if it does come in contact, immediately wipe area and wash off with water.

To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.

Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

PRECAUTIONS
Revision: 2006 November2007 350Z

Use flare nut crowfoot and torque wrench when removing and
installing brake tube.

When installing brake piping, be sure to check torque.

Before working, turn the ignition switch OFF and disconnect the
connectors of ABS actuator and control unit or the battery nega-
tive terminal.

Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to BR-38, "
Brake Burnishing Procedure" .
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.SBR686C

BRAKE FLUID

BRAKE FLUIDPFP:KN100
On-Vehicle InspectionNFS00008
LEVEL CHECK

Check that the fluid level in the reservoir tank is within the stan-
dard (between MAX and MIN lines).

Visually check around the reservoir tank for fluid leaks.

If fluid level is excessively low, check brake system for leaks.

If warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Drain and RefillNFS00009
CAUTION:

Refill with new brake fluid “DOT3”.

Do not reuse drained brake fluid.

Do not let brake fluid come in contact with painted surfaces on the body. This might damage the
paint, so if it does come in contact, immediately wipe area and wash off with water.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually
remove the brake fluid.
3. Before working, turn the ignition switch OFF and disconnect the
connectors of ABS actuator and control unit or battery negative
terminal.
4. Make sure there is no foreign material in the reservoir tank, and
refill with new brake fluid.
5. Rest foot on brake pedal. Loosen bleed valve. Slowly depress
pedal until it stops. Tighten bleed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.
Bleed Air. Refer to BR-11, "
Bleeding Brake System" .

Bleeding Brake SystemNFS0000A
CAUTION:
While bleeding, pay attention to master cylinder fluid level.
1. Before working, turn the ignition switch OFF and disconnect the connectors of ABS actuator and control
unit or battery negative terminal.
2. Connect a vinyl tube to the rear right bleed valve.
3. Fully depress brake pedal 4 to 5 times.
4. With the brake pedal depressed, loosen the bleed valve to let the air out, and then tighten it immediately.
5. Repeat steps 3, 4 until no more air comes out.
6. Tighten the bleed valve to the specified torque. Refer to BR-27, "
Components" (Front) and BR-40, "Com-
ponents" (Rear).
7. In steps 2 to 6 below, with the master cylinder reservoir tank filled at least half way, bleed air from the front
left, rear left, and front right tires, in that order.
