Service Notice
IWhen removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.
IHandle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to oil
or damage them.
IApply sealing compound where necessary when installing parts.
IWhen applying sealing compound, be careful that the sealing compound does not protrude from parts.
IWhen replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust pre-
vention measures.
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 R20 is as follows (The compo-
sition varies according to the destination and optional equipment.):
IFor a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing 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.
IFor 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 theRSsection of 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 should 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. For removal of Spiral Cable and Air
Bag Module, see the RS section.
IDo 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.

Removal and Installation
IWhen removing or installing hood, place a cloth or other padding on hood. This prevents vehicle body from
being scratched.
IBumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
IHood adjustment: Adjust at hinge portion.
IHood lock adjustment: After adjusting, check hood lock control operation. Apply a coat of grease to hood
locks engaging mechanism.
IHood opener: Do not attempt to bend cable forcibly. Doing so increases effort required to unlock hood.

Removal and Installation
IWhen removing or installing back door, place a cloth or other padding on back door. This prevents vehicle
body from being scratched.
IBumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
IBack door adjustment: Adjust at hinge-back door portion for proper back door fit.
IBack door lock system adjustment: Adjust striker so that it is in the center of the lock. After adjustment,
check back door lock operation.
IAfter installation, make sure that back door and fuel filler lid open smoothly.

Measurement of Compression Pressure
1. Warm up engine and switch off the ignition switch.
2. Remove glow plate and glow plugs.
3. Fit compression gauge adapter to cylinder head.
Compression gauge adapter:
:15-20N×m
(1.5 - 2.0 kg-m, 11 - 14 ft-lb)
4. Ensure the ignition switch is in the ªLOCKº position and discon-
nect harness connector (gray colored) from injection pump.
5. Crank engine, then read gauge indication.
IAlways use a fully-charged battery to obtain specified
engine revolution.
IEngine compression measurement should be made as
quickly as possible.
Compression pressure:
Unit: kPa (bar, kg/cm2, psi)/200 rpm
Standard 2,942 (29.4, 30, 427)
Minimum 2,452 (24.5, 25, 356)
Differential limit between cylinders 294 (2.9, 3, 43)
6. If cylinder compression in one or more cylinders is low, pour a
small amount of engine oil into cylinders through the glow holes
and retest compression.
IIf adding oil helps the compression pressure, piston rings
may be worn or damaged.
IIf pressure stays low, valve may be sticking or seating
incorrectly.
IIf cylinder compression in any two adjacent cylinders is
low, and if adding oil does not help the compression, there
is leakage past the gasket surface.
Leakage past the cylinder gasket can result in oil and water
becoming mixed in the engine block cooling and lubrica-
tion chambers.
