PRECAUTIONS

PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT A

BELT PRE-TENSIONER"

NFS00001

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B

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.

C

Information necessary to service the system safely is included in the SRS and SB section of this Service Man-

ual.

WARNING:

D

q 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.

E

q 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.

BR

q 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.

G

Precautions for Battery Service

NFS00002

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the H 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 Cover

I
NFS000HT

When performing the procedure after removing cowl top cover, cover

the lower end of windshield with urethane, etc.

J

L

PIIB3706J

Precautions for Brake System

M
NFS00003

q Recommended fluid is brake fluid "DOT 3". Refer to MA-11, "Fluids and Lubricants" .
q Do not reuse drained brake fluid.
q 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.

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

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

Revision: 2006 November

BR-3

2007 350Z

PRECAUTIONS
q Use flare nut crowfoot and torque wrench when removing and installing brake tube.
q When installing brake piping, be sure to check torque. q Before working, turn the ignition switch OFF and disconnect the
connectors of ABS actuator and control unit or the battery negative terminal. q 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.

OPERATING CHECK With the engine stopped, change the vacuum to the atmospheric pressure by depressing the brake pedal several times. Then with brake pedal fully depressed, start the engine and when the vacuum pressure reaches the standard, check that the clearance between the brake pedal and floor panel decreases. CAUTION: Depressing pedal interval is approximately 5 seconds.
AIRTIGHT CHECK q Run the engine at idle for approximately 1 minute, and stop it
after applying vacuum to the booster. Depress the brake pedal normally to change the vacuum to the atmospheric pressure. Check that distance between the brake pedal and floor panel gradually increases. q 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. CAUTION: Depressing pedal interval is approximately 5 seconds.

1. Insert a piece of wood as shown in the figure, blow air in through the flare nut mounting hole, and remove the piston and piston boot. If the four pistons do not all come out at the same time, press the piston(s) that have come out a ways into the cylinder body and blow air in again.

CAUTION: Do not get fingers caught in the piston.

2. Remove the piston boot from the piston.

3. Using a flat-bladed screwdriver, remove the piston seal.
CAUTION: q Be careful not to damage cylinder inner wall.
q Never remove the four bolts from the inner and outer sides of the caliper. Do not tighten them further, either.

Brake Burnishing Procedure

NFS000AX

Burnish the brake pad and disc rotor mutually contacting surfaces of disc rotor according to following procedure after refinishing or replacing disc rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION: q Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.
q Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road. 2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
