SERVICE INFORMATION
PRECAUTIONS
Precaution for 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 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 Manual.
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 must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
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.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.

Precaution INFOID:0000000005283980
• 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 sliding
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.

TRIPLE-CONE SYNCHRONIZER
Revision: January 2010 2010 Sentra
MT-10
DESCRIPTION
< SERVICE INFORMATION >
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)
