Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS composition which is available to NISSAN MODEL Y61 is as follows (The composition varies
according to the destination.):
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), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
WARNING:
+To 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 in¯ation, all maintenance must be performed
by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
+Do 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 either just before
the harness connectors or for the complete harness are related to the SRS.

PRECAUTIONS AND PREPARATION
MA-1

4. Check oil level.
5. Start engine. Check area around drain plug and oil ®lter for any
sign of oil leakage.
6. Run engine for a few minutes, then turn it off. After several
minutes check oil level.
Changing Engine Oil Filter
1. Remove oil ®lter with Tool.
WARNING:
Be careful not to burn yourself, as the engine and engine oil
are hot.
2. Clean oil ®lter mounting surface on cylinder block. Coat rubber
seal of new oil ®lter with engine oil.
3. Screw in the oil ®lter until a slight resistance is felt, then tighten
an additional 2/3 of a turn.
4. Add engine oil.
Refer to Changing Engine Oil.
+Clean excess oil from engine.
Changing Engine Coolant
WARNING:
To avoid the danger of being scalded, never change the cool-
ant when the engine is hot.
ÐDRAINING ENGINE COOLANTÐ
1. Move heater TEMP control knob all the way to HOT.
2. Open radiator drain plug at the bottom of radiator.
3. Remove radiator ®ller cap.
Remove reservoir tank, drain coolant, then clean reservoir tank.
Install it temporarily.
+Be careful not to allow coolant to contact drive belts.

4. Remove cylinder block drain plug located at left rear of cylin-
der block.
5. Drain coolant and install reservoir tank, cylinder block drain
plug and radiator drain plug.
6. Fill radiator with water and warm up engine.
7. Stop engine and wait until it cools down.
8. Repeat step 2 through step 7 two or three times.
9. Drain water.
ÐREFILLING ENGINE COOLANTÐ
10. Install reservoir tank, radiator drain plug, and cylinder block
drain plugs.
+Apply sealant to the thread of cylinder block drain plug.
Cylinder block drain plug:
:34-44Nzm (3.5 - 4.5 kg-m, 25 - 33 ft-lb)
11. Fill radiator and reservoir tank with coolant up to the MAX level
and install radiator cap.
For coolant mixture ratio, refer to MA-11.
Coolant capacity (With reservoir tank):!(Imp qt)
RHD models
Without rear heater 11.8 (10-3/8)
With rear heater 12.9 (11-3/8)
LHD models
Without rear heater 11.6 (10-1/4)
With rear heater 12.7 (11-1/8)
Reservoir tank capacity (for MAX level):
1.2!(1-1/8 Imp qt)
Pour coolant through coolant ®ller neck slowly to allow air in
system to escape.
12. Warm up engine to normal operating temperature.
13. Run engine at 2,000 rpm for 10 seconds and return to idle
speed.
+Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
14. Stop engine and cool it down.
+Cool down using a fan to reduce the time.
15. Remove the radiator ®ller cap and check coolant level.
+If necessary, re®ll radiator up to ®ller neck with coolant.
16. Re®ll reservoir tank to Max line with coolant.
17. Repeat step 12 through step 16 two or more times.
18. Warm up engine, and check for sound of coolant ¯ow while
running engine from idle up to 2,000 rpm with heater tempera-
ture control set at several positions between COOL and HOT.
+Sound may be noticeable at heater water cock.
19. If sound is heard, bleed air from cooling system by repeating
steps 12 through 16 until coolant level no longer drops.
+Clean excess coolant from engine.

Checking Cooling System
CHECKING HOSES AND CLAMPS
Check hoses and clamps for proper attachment, leaks, cracks,
damage, loose connections, cha®ng and deterioration.
CHECKING RADIATOR CAP
Apply pressure to radiator cap with cap tester to see if it is satis-
factory.
Radiator cap relief pressure:
78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 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:
98 kPa (0.98 bar, 1.0 kg/cm
2, 14 psi)
CAUTION:
Use of higher pressure than the speci®ed 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 ®lter for fuel leakage, damage and other abnormal
signs.
REPLACING FUEL FILTER
1. Disconnect harness connector and drain fuel.
