Supplement Restraint System (SRS) ªAIR BAGº
and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System ªAir Bagº and ªSeat Belt Pre-tensionerº, used along with a seat belt, help
to reduce the risk or severity or injury to the driver and front passenger in a collision. The Supplemental
Restraint System consists of an air bag module (located in the center of the steering wheel and on the instru-
ment panel on the passenger side, where fitted), seat belt pre-tensioners, a diagnosis sensor unit, warning
lamp, wiring harness and spiral cable. Information necessary to service the system safely is included in the
BT sectionof this Service Manual.
WARNING:
ITo 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 dealer.
IImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
IDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses (except ªSEAT BELT-TENSIONERº connector) can be iden-
tified with yellow harness connector and with yellow harness protector or yellow insulation tape
before the harness connectors.
Precautions
IUse only ªDOT 4º fluid from a sealed container.
INever reuse drained brake fluid.
IBe 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.
ITo clean master cylinder parts, disc brake caliper parts or
wheel cylinder parts, use clean brake fluid.
INever use mineral oils such as Petrol or kerosene. They
will ruin rubber parts of hydraulic system.
IUse flare nut wrench when removing and installing brake
tubes.
IAlways torque brake lines when installing.
IBurnish 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 speed. Refer to ªBrake
Burnishing Procedureº, ªCheck and Adjustmentº, BR-5.
WARNING:
IClean brakes with a vacuum dust collector to minimize risk
of health hazard from airborne materials.
IAvoid prolonged and repeated skin contact with brake
fluid.
IWear protective clothing, including impervious gloves.
IWhere there is a risk of eye contact, eye protection should
be worn Ð for example chemical goggles or face shield.

PRECAUTIONS AND PREPARATION
BR-3

5. Bleed the air from the rear brake piping.
6. To adjust the LSV correctly, proceed as follows:
a. With unladen vehicle (12 liters of fuel, radiator coolant and
engine oil are full). Spare tire, hand tools and mats in desig-
nated positions. Check the length of LSV spring ªLº.
b. If the spring length is different from that specified, move the
regulation lever (2) until the specified value is obtained. Move
the LSV lever (1) until it contacts the stopper bolt and recheck
the spring length.
Sensor spring length ªLº
Hardtop: 201 mm (7.913 in)
Wagon: 197.5 mm (7.776 in)
NOTE: Do not disturb stopper bolt.
c. Start the engine and run it at idling speed.
d. Slowly depress the brake pedal until an input pressure of 4,805
kPa (48.1 bar, 49 kg/cm
2, 697 psi) is obtained (at the front axle
pressure gauge) and an output pressure of 1,736 - 2,501 kPa
(18 - 26 bar, 17.7 - 25.5 kg/cm
2, 252 - 363 psi) is obtained (at
the rear axle pressure gauge).
If the output pressure at the rear axle pressure gauge is not within
the specified values, adjust LSV spring length as described under
b) until the output pressure measured is within the specified range.
Unit: kPa (bar, kg/cm2, psi)
Front axle* 4,805 (48.1, 49.0, 697)
Rear axle* 1,736 - 2,501 (18 - 26, 17.7 - 25.5, 252 - 363)
* Load conditions as indicated under 6.a, driver seat occupied.
