Precautions for Multiport Fuel Injection System
or Engine Control System
1. Before connecting or disconnecting any harness connector forthe multiport fuel injection system or ECM (Engine Control
Module):
Turn ignition switch to ªOFFº position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
2. Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure to eliminate danger.
3. Be careful not to jar components such as control unit and air flow meter.
Precautions for Catalyst
If a large amount of unburned fuel enters the converter, the con-
verter temperature will rise to excessively high values. To prevent
this, follow the procedure below:
1. Use unleaded gasoline only. Leaded gasoline will seriouslydamage the catalytic converter.
2. When checking for ignition spark or measuring engine compression, perform tests quickly and only when necessary.
3. Do not run engine when the fuel tank level is low, as a result the engine may misfire causing damage to the converter.
4. Do not place the vehicle on inflammable material. Keep inflam- mable material off the exhaust pipe.
Precautions for Turbocharger
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean
supply of oil flowing through the turbocharger and to follow all
required maintenance instructions and operating procedures.
For proper operation of the system, follow the procedure below:
1. Always use the recommended oil. Follow the instructions forproper time to change the oil and proper oil level.
2. Avoid accelerating engine to a high rpm immediately after start- ing.
3. If engine had been operating at high rpm for an extended period of time, let it idle for a few minutes prior to shutting it off.

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.
ItemReference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be checked periodically, unless otherwise specified.
Tires Check 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 blades Check for cracks or wear if not functioning correctly. Ð
Doors and engine hood Check 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 rotation Tires 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.

are all operating correctly and installed securely. Also check headlight aim. Ð
Warning lights and buzzers/chimes Make sure that all warning lights and buzzers/chimes are
functioning correctly. Ð
Steering wheel Check 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 belts Check 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

12. Fill reservoir tank up to ªMAXº level, and re-install radiator cap.
13. Run the engine at approximately 2,000 rpm for about oneminute.
14. Stop engine and cool it down, then refill the radiator and the reservoir tank up to the specified level.
Checking Cooling System
CHECKING HOSES
Check hoses for proper attachment, leaks, cracks, damage, loose
connections, chafing and deterioration.
CHECKING RADIATOR CAP
Apply pressure to radiator cap by means of a cap tester to see if it
is satisfactory. Radiator cap relief pressure:78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system by means of a tester to check
for leakage. Testing pressure:157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher than the specified pressure may cause radiator dam-
age.
Checking and Replacing fuel filter and Draining
Water
Be careful not to spill fuel in engine compartment. Place a rag
to absorb fuel.
REPLACING FUEL FILTER
1. Remove fuel filter sensor and drain fuel.

Pinch the rubber cap located under the cyclone air cleaner assem-
bly to remove dust.
Checking Injection Nozzle
WARNING:
When using nozzle tester, do not allow fuel sprayed from
nozzle to contact your hand or body, and make sure that your
eyes are properly protected with goggles.
1. Check initial injection pressure by pumping tester handle onetime per second.Initial injection pressure: Used Nozzle12,259 - 12,749 kPa
(122.6 - 127.5 bar, 125 - 130 kg/cm
2,
1,778 - 1,849 psi)
New Nozzle 12,749 - 13,730 kPa
(127.5 - 137.3 bar, 130 - 140 kg/cm
2,
1,849 - 1,991 psi)
I Always check initial injection pressure before installing
new nozzle.
Do not disassemble injection nozzle assembly. Entrust disas-
sembly or adjustment to BOSCH service shop.
2. Check spray pattern by pumping tester handle 4 to 6 times or more per second.
a. If main spray angle is within 30 degrees as shown, injec- tion nozzle is good.
b. It is still normal even if a thin stream of spray deviates from the main spray (pattern B).
3. If spray is not correct, clean injection nozzle tip or replace it.

CHECKING RADIATOR CAP
Apply pressure to radiator cap (side with pressure valve) with cap
tester to see if it is satisfactory.Radiator cap relief pressure:108 - 128 kPa
(1.08 - 1.28 bar, 1.1 - 1.3 kg/cm
2, 16 - 18 psi)
Pull the negative-pressure valve to open it. Check that it closes
completely when released.
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system with cap tester to check for
leakage. Testing pressure:157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Use of higher pressure than the specified value may cause
damage to radiator.
Checking and Replacing Fuel Filter and
Draining Water
Be careful not to spill fuel in engine compartment. Place a rag
to absorb fuel.
CHECKING FUEL FILTER
Check fuel filter for fuel leakage, damage and other abnormal
signs.
REPLACING FUEL FILTER
1. Disconnect harness connector and drain fuel.
2. Remove fuel filter using band-type filter wrench.
3. Remove fuel filter and fuel filter sensor.
CAUTION:
Remove fuel filter without spilling fuel. If spilt, wipe off imme-
diately. Be specially careful not to spill fuel on engine mount
insulator.
