Check the seat belt buckles, webbing, retractors, anchors and adjusters. Replace any seat belt assembly as
necessary. Refer to SB-8, "
Seat Belt Inspection" .

Check the seat belt anchors for loose bolts, damage, or excessive wear.

Check the seat belt webbing for any damage, cuts, fraying, or excessive wear.

CHASSIS AND BODY MAINTENANCE
Revision: June 20062007 Versa

Check the retractor for smooth operation.

Check the function of the buckles by inserting the seat belt tongue and checking for proper engagement of
the buckle and press the button on the buckle to check for proper release of the seat belt tongue.
CAUTION:

After any collision, inspect all seat belt assemblies, including retractors and other attached com-
ponents, such as the guide rail set. NISSAN recommends replacing all seat belt assemblies in use
during a collision, unless they are not damaged and are inspected to confirm they are operating
properly after a minor collision.
Also inspect all seat belt assemblies that are not in use during a collision, and replace any compo-
nents if damaged or not operating properly. The seat belt pre-tensioner should be replaced even if
the seat belts are not in use during a frontal collision where the driver and passenger air bags
have been deployed.

If any component of the seat belt assembly is suspected of being damaged or not operating prop-
erly, do not repair the component. Replace the components as an assembly.

If the seat belt webbing is cut, frayed, or damaged then replace the seat belt assembly.

Never lubricate the seat belt buckle or tongue.

When replacing any seat belt assembly always use a Genuine NISSAN seat belt assembly.

PRECAUTIONS
Revision: June 20062007 Versa
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS00GLL
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WAR NIN G:

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 must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
PrecautionsUCS005LD

If transaxle assembly is removed from the vehicle, always replace CSC (Concentric Slave Cylinder).
Installed CSC returns to the original position when removing transaxle assembly. Dust on clutch disc slid-
ing parts may damage CSC seal, and may cause clutch fluid leakage.

Do not reuse transaxle oil.

Drain, fill and check transaxle oil with the vehicle on level surface.

During removal or installation, keep inside of transaxle clear of dust or dirt.

Check for the correct installation orientation prior to removal or disassembly. If matching marks are
required, be certain they do not interfere with the function of the parts they are applied to.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, follow it.

Be careful not to damage the sliding surfaces and mating surfaces of parts.

DESCRIPTION

TRIPLE-CONE SYNCHRONIZER
Triple-cone synchronizer is used for the 1st and the 2nd gears to
reduce operating force of the shift lever.

1st main gear (1)

1st-2nd coupling sleeve (2)

Insert key (3)

Outer baulk ring (4)

2nd main gear (5)

Synchronizer cone (6)

Inner baulk ring (7)

1st-2nd synchronizer hub (8)
REVERSE GEAR NOISE PREVENTION FUNCTION (SYNCHRONIZING METHOD)
Reverse gear assembly consists of reverse input gear, return spring,
reverse baulk ring and reverse output gear. When the shift lever is
shifted to the reverse position, the construction allows smooth shift
operation by stopping the reverse idler shaft rotation by frictional
force of synchronizer.

Reverse fork rod (1)

Reverse output gear (2)

Return spring (3)

Reverse baulk ring (4)

Reverse input gear (5)
