CAUTION:
IBe careful not to drop or damage catalytic converter.
INever wet catalytic converter with water, oil, etc.
IAlways replace exhaust gaskets with new ones when reas-
sembling.
If gasket is left on flange surface, scrape off complete as
shown at left.
IWith engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.
IAfter installation, but before fully tightening exhaust joints,
check to ensure that mounting brackets and mounting
insulators are free from undue stress. If any of the above
parts are not installed properly, excessive noise or vibra-
tion may be transmitted to the vehicle body.

Engine compartment
There are several reasons a vehicle or engine vibration could
cause an electrical complaint. Some of the things to check for are:
IConnectors not fully seated.
IWiring harness not long enough and is being stressed due to
engine vibrations or rocking.
IWires laying across brackets or moving components.
ILoose, dirty or corroded ground wires.
IWires routed too close to hot components.
To inspect components under the hood, start by verifying the integ-
rity of ground connections. (Refer to GROUND INSPECTION
described later.) First check that the system is properly grounded.
Then check for loose connection bygently shakingthe wiring or
components as previously explained. Using the wiring diagrams
inspect the wiring for continuity.
Behind the instrument panel
An improperly routed or improperly clamped harness can become
pinched during accessory installation. Vehicle vibration can aggra-
vate a harness which is routed along a bracket or near a screw.
Under seating areas
An unclamped or loose harness can cause wiring to be pinched by
seat components (such as slide guides) during vehicle vibration. If
the wiring runs under seating areas, inspect wire routing for pos-
sible damage or pinching.
HEAT SENSITIVE
The owner's problem may occur during hot weather or after car has
sat for a short time. In such cases you will want to check for a heat
sensitive condition.
To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
Do not heat components above 60ÉC (140ÉF).If incident occurs
while heating the unit, either replace or properly insulate the com-
ponent.

WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
Wrap a thick cloth around the cap. Slowly turn it a quarter turn
to allow built-up pressure to escape. Carefully remove the cap
by turning it all the way.

CHECKING COOLING SYSTEM FOR LEAKS
To check for leakage, apply pressure to the cooling system with a
tester.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher pressure than specified may cause radiator damage.
CHECKING RADIATOR CAP
To check radiator cap, apply pressure to cap with a tester.
Radiator cap relief pressure:

General maintenance includes those items which should be checked during normal day-to-day operation of
the vehicle. They are essential if the vehicle is to continue functioning correctly. Owners can perform the
checks and inspections themselves, or they can be carried out by a NISSAN dealer.
Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be checked periodically, unless otherwise specified.
TiresCheck the pressure with a gauge weekly when at a service station, including the spare,
and adjust to the specified pressure if necessary. Check carefully for damage, cuts or excessive
wear.Ð
Windshield wiper bladesCheck for cracks or wear if not functioning correctly. Ð
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
function correctly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure
that the secondary latch prevents the hood from opening when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lubrication more
often.MA-45
Tire rotationTires should be rotated every 5,000 km (3,000 miles). MA-43
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the vehicle etc.
LightsMake sure that the headlights, stop lights, tail lights, turn signal lights, and other lights
are all operating correctly and installed securely. Also check headlight aim.Ð
Warning lights and buzzers/chimesMake sure that all warning lights and buzzers/chimes are
functioning correctly.Ð
Steering wheelCheck that it has the specified play. Check for changes in the steering
operation, such as excessive free play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)Ð
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the belt webbing for
cuts, fraying, wear of damage.MA-46
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the
engine oil or refuel.
Windshield washer fluidCheck that there is adequate fluid in the tank.
Engine coolant levelCheck the coolant level when the engine is cold. MA-22
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off the
engine.MA-21
Brake and clutch fluid levelMake sure that the brake fluid level is between the ªMAXº and
ªMINº lines on the reservoir.MA-36/MA-40
BatteryCheck the fluid level in each cell. It should be between the ªMAXº and ªMINº lines. Ð

Precautions
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 composition which is available to NISSAN MODEL R20 is as follows (The composition
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).
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.
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.
PRECAUTIONS FOR SRS ªAIR BAGº AND ªSEAT BELT PRE-TENSIONERº SERVICE
IDo not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
IBefore servicing the SRS, turn ignition switch ªOFFº, disconnect both battery cables and wait at least 3
minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
IDiagnosis sensor unit must always be installed with their arrow marks ª+º pointing towards the front of
the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
IThe spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
IHandle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and place front side air bag module (built-in type) standing with stud bolt side setting
bottom.
IConduct self-diagnosis to check entire SRS for proper function after replacing any components.
IAfter air bag inflates, the front instrument panel assembly should be replaced if damaged.
