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.

PRE-DELIVERY INSPECTION ITEMS
MA-2

General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them.
Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise
speci®ed.
TiresCheck the pressure with a gauge periodically when at a service station, including the
spare, and adjust to the speci®ed pressure if necessary. Check carefully for damage, cuts or
excessive wear.Ð
Windshield wiper bladesCheck for cracks or wear if they do not wipe properly. Ð
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
operate properly. Also ensure that all latches lock securely. Lubricate hinges, latches, rollers and
links if necessary. Make sure that the secondary latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lubrication fre-
quently.MA-27
Tire rotationTires should be rotated every 5,000 km (3,000 miles) for 4WD models. MA-25
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 properly and installed securely. Also check headlight aim.Ð
Warning lights and chimesMake sure that all warning lights and chimes are operating prop-
erly.Ð
Steering wheelCheck for change in the steering conditions, 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 or damage.MA-27
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 ¯uidCheck that there is adequate ¯uid in the tank. Ð
Engine coolant levelCheck the coolant level when the engine is cold. MA-14, 15
Engine oil levelCheck the level after parking the vehicle on a level spot and turning off the
engine.MA-13, 14
Brake and clutch ¯uid levelMake sure that the brake and clutch ¯uid levels are between the
``MAX'' and ``MIN'' lines on the reservoir.MA-20, 23
BatteryCheck the ¯uid level in each cell. It should be between the ``MAX'' and ``MIN'' lines. Ð
GENERAL MAINTENANCE
MA-3

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.
