Road TestNCAT0028DESCRIPTIONNCAT0028S01IThe purpose of the test is to determine overall performance of
CVT and analyze causes of problems.
IThe road test consists of the following three parts:
1. Check before engine is started
2. Cruise test
IBefore road test, familiarize yourself with all test procedures
and items to check.
IConduct tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. The SRS system composition which is available to NISSAN MODEL P11 is as follows (The
composition varies according to the destination and optional equipment.):
lFor a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the
steering wheel), front passenger air bag module (located on the instrument panel on passenger side),
front seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
lFor a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a
frontal collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
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 should 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. For removal of Spiral Cable and
Air Bag Module, see the RS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions for Brake System
lRecommended fluid is brake fluid ªDOT 4º.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas.
lTo clean or wash all parts of master cylinder, disc brake
caliper and wheel cylinder, 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
tube.
lAlways torque brake lines when installing.
lBurnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to ªBrake Burnishing Procedureº, ªCheck and
Adjustmentº, BR-7.
WARNING:
lClean brake pads with a waste cloth, then wipe with a
dust collector.

PRECAUTIONS
BR-3

Precautions When Working On ABS
lUse recommended tyres in combination with ABS.
lInstall tyres or studded tyres, etc. with the same size.
lIf different sizes of tyres, or tyres other than the ones
recommended for use with the ABS, are fitted, stopping
distance will increase and control and stability could
deteriorate.
lWhen changing brake pads, use Nissan genuine parts.
lWhen fitting radios etc, do not position the radio unit,
antenna, or antenna cables within an area of about 100
mm (3.94 in) of the control unit.
lWhen doing any work that requires electro-welding, first
remove the control unit.
lMake sure when taking a power supply for the audio,
lamps etc., not to take this from any ABS-related har-
ness. (Refer to the electrical wiring diagrams for ABS-
related harnesses)
