The following tables show the normal maintenance schedule. Depending upon weather and atmospheric
conditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent
maintenance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.

Checking Drive Belt
+Because an auto tensioner adjustment mechanism is
provided, it is not necessary to check or adjust the ten-
sion of accessory belt.
1. Inspect for cracks, fraying, wear or oil adhesion. Replace if
necessary.
The belts should not touch the bottom of the pulley groove.
2. Check the damper unit of the auto tensioner for oil leaks.

Removal
WATER PUMP, ALTERNATOR AND AIR
CONDITIONER BELT
1. Remove radiator shroud.
2. Contract and hold the auto tensioner using the following pro-
cedure.
a. Securely hold the 19 mm (0.75 in) hexagonal portion A of
auto tensioner with a closed wrench.
+Preferably use a tool with a handhold of 500 mm (19.69 in)
or more in length.
+No bolts or nuts are required to be loosened during the
operation.
b. Turn the hexagonal portion A in the direction shown by the
arrow to contract the damper unit of the auto tensioner.
CAUTION:
+Because the tensioner has a high tension, it shall be
securely held and turned with a closed wrench.
+Because the hexagonal portion A of the tensioner is
made of aluminum and may be damaged by sudden
input, turn it slowly according to the contraction of the
damper unit.
3. Remove the belt from the alternator pulley first, and then
remove it from the other pulleys.
+If the tensioner is not held firmly, your finger may get caught
between the belt and the pulleys. Confirm the holding of the
tensioner, and then hold the belt side in the place away from
the pulleys to attach or remove the belt, paying attention to
prevent your finger from being caught.
CAUTION:
+When handling the belt, pay attention to prevent the oil
or coolant from adhering to the belt.
+Do not distort or bend the belt intensively.
Installation
+Install the belt in the reverse order of removal.
+After installation of the belt, confirm that the belt engages the
pulleys securely.
+Depending on the engagement between the belt and the idler
pulley, noise (belt noise) may be heard when the engine is
started just after installation. This noise will stop with time.
Changing Engine Oil
WARNING:
+Be careful not to burn yourself, as engine oil is hot.
+Prolonged and repeated contact with used engine oil
may cause skin cancer; try to avoid direct skin contact
with used oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Remove drain plug and oil filler cap.

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.
