draining. Do not remove drain cock by loosening it exces-
sively.
If water does not drain properly, move the priming pump up and
down.
Type B
Loosen air bleeder screw from the sedimentor cover and then
loosen drain cock and drain water.
Loosening drain cock four to five turns causes water to start
draining. Do not remove drain cock by loosening it exces-
sively.
2. Bleed air.
Refer to ªAir Bleedingº in EC section.
Checking Fuel Lines
Check fuel lines and tank for proper attachment, leaks, cracks,
damage, loose connections, chafing and deterioration.
CAUTION:
Keep clean parts with compressed air when assembling.

(``Removal'', ``REMOVAL AND INSTALLATION'').
8. Support engine by placing a jack under oil pan.
lDo not place jack under the oil pan drain plug.
9. Remove transmission with transfer from engine.
WARNING:
Support Manual Transmission with transfer, while removing
it.

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 Y61 is as follows (The com-
position varies according to the destination and optional equipment.):
+For 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),
seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), 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:
+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 inflation, all maintenance should be per-
formed 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 tape either just
before the harness connectors or for the complete harness are related to the SRS.
PRECAUTION
RS-1002

Precautions for SRS ªAIR BAGº and ªSEAT
BELT PRE-TENSIONERº Service
+Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
+Before 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.
+Diagnosis sensor unit must always be installed with their arrow marks ªSº 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.
+The 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.
+Handle air bag module carefully. Always place driver and passenger air bag modules with the pad side
facing upward and front side air bag modules (built-in type) with the stud bolt side facing down.
+Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
+After air bag inflates, the front instrument panel assembly should be replaced if damaged.

Description
The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the ªONº or ªSTARTº
position.
The collision modes for which supplemental restraint systems are activated are different among the SRS
systems. For example, the driver air bag module and passenger air bag module are activated in a frontal
collision but not in a side collision.
SRS configurations which are activated for some collision modes are as follows;
SRS configuration Frontal collision Left side collision Right side collision
