When you read wiring diagrams:
lRead GI section, ``HOW TO READ WIRING DIAGRAMS''.
lSee EL section, ``POWER SUPPLY ROUTING'' for power distribution circuit.
When you perform trouble diagnoses, read GI section, ``HOW TO FOLLOW FLOW
CHART IN TROUBLE DIAGNOSES'' and ``HOW TO PERFORM EFFICIENT DIAGNOSIS
FOR AN ELECTRICAL INCIDENT''.

Supplemental Restraint System (SRS) ``AIR
BAG'' (4WD models)
The Supplemental Restraint System ``AIR BAG'', used along with a seat belt, helps to reduce the risk or
severity of injury to the driver in a frontal collision. The Supplemental Restraint System consists of air bag
module (located in the center of the steering wheel), a diagnosis sensor unit, warning lamp, wiring harness
and spiral cable. Information necessary to service the system safely is included in theRS sectionof this
Service Manual.
WARNING:
lTo 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.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses are covered with yellow insulation either just before the
harness connectors or for the complete harness, for easy identification.
Supplemental Restraint System (SRS) ``AIR
BAG'' (2WD models)
The Supplemental Restraint System ``AIR BAG'', used along with a seat belt, helps to reduce the risk or
severity of injury to the driver in a frontal collision. The Supplemental Restraint System consists of an air
bag module (located in the center of the steering wheel), a diagnosis sensor unit, warning lamp and spiral
cable. Information necessary to service the system safely is included in theRS sectionof this Service
Manual.
WARNING:
lTo 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.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS.
Precautions for Brake System
lUse brake fluid DOT 3 or DOT 4*1.
lNever reuse drained brake fluid.
lBe 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.
lTo clean master cylinder parts, disc brake caliper parts
or wheel cylinder parts, use clean brake fluid.
lNever use mineral oils such as gasoline or kerosene.
They will ruin rubber parts of the hydraulic system.
lUse flare nut wrench when removing and installing brake
tubes.
lAlways torque brake lines when installing.
WARNING:
lClean brakes with a vacuum dust collector to minimize
the hazard of airborne materials.
*1: Refer to MA section (``Fluids and Lubricants'', ``RECOM-
MENDED FLUIDS AND LUBRICANTS'').

PRECAUTIONS AND PREPARATION

Checking Brake Fluid Level
lCheck fluid level in reservoir tank. It should be between Max
and Min lines on reservoir tank.
lIf fluid level is extremely low, check brake system for leaks.
lIf the brake warning lamp comes on, check brake fluid level
switch and parking brake switch.
Checking Brake Line
CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration
or other damage. Replace any damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Changing Brake Fluid
CAUTION:
lRefill with new brake fluid DOT 3 or DOT 4*1.
lAlways keep fluid level higher than minimum line on
reservoir tank.
lNever reuse drained brake fluid.
lBe 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.
1. Clean inside of reservoir tank, and refill with new brake fluid.
2. Connect a vinyl tube to each air bleeder valve.
3. Drain brake fluid from each air bleeder valve by depressing
brake pedal.
4. Refill until brake fluid comes out of each air bleeder valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid. Refer to ``Bleeding Brake System'', BR-4.
*1: Refer to MA section (``Fluids and Lubricants'', ``RECOM-
MENDED FLUIDS AND LUBRICANTS'').

Bleeding Brake System
CAUTION:
lCarefully monitor brake fluid level at master cylinder
during bleeding operation.
lIf master cylinder is suspected to have air inside, bleed
air from master cylinder first. Refer to ``Installation'',
``MASTER CYLINDER'', BR-14.
lFill reservoir with new brake fluid DOT 3 or DOT 4*1.
Make sure it is full at all times while bleeding air out of
system.
lPlace a container under master cylinder to avoid spillage
of brake fluid.
lFor models with ABS, turn ignition switch OFF and dis-
connect ABS actuator connector or battery cable.
lBleed air in the following order.
a. LSV air bleeder
b. Left rear brake
c. Right rear brake
d. Left front brake
e. Right front brake
*1: Refer to MA section (``Fluids and Lubricants'', ``RECOM-
MENDED FLUIDS AND LUBRICANTS'').
1. Connect a transparent vinyl tube to air bleeder valve.
2. Fully depress brake pedal several times.
3. With brake pedal depressed, open air bleeder valve to
release air.
4. Close air bleeder valve.
5. Release brake pedal slowly.
6. Repeat steps 2 through 5 until clear brake fluid comes out of
air bleeder valve.
7. Tighten air bleeder to the specified torque.

REMOVAL
CAUTION:
lBe 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.
lAll hoses must be free from excessive bending, twisting
and pulling.

2. Drain brake fluid from each air bleeder valve by depressing
brake pedal.
3. Remove flare nut connecting brake tube and hose, then with-
draw lock spring.
4. Cover openings to prevent entrance of dirt whenever discon-
necting brake line.
INSPECTION
Check brake lines (tubes and hoses) for cracks, deterioration or
other damage. Replace any damaged parts.
