Checking A/T FluidINFOID:0000000001704747
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Before driving, A/T fluid level can be checked at A/T fluid tem-
peratures of 30 to 50°C (86 to 122°F) using the “COLD” range
on A/T fluid level gauge.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free cloth.
CAUTION:
When wiping the A/T fluid level gauge, always use lint-free
cloth.

Checking Seat Belts, Buckles, Retractors, Anchors and AdjustersINFOID:0000000001704758
Check the seat belt buckles, webbing, retractors, anchors and adjusters. Replace any seat belt assembly as
necessary. Refer to SB-7, "
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.
• 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 compo-
nents, such as the guide rail set. NISSAN recommends replacing all seat belt assemblies in use dur-
ing 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.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703128
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.
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 har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001844076
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
PrecautionINFOID:0000000001703129
• 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 tight-
ening sequence is specified, follow it.
• Be careful not to damage the sliding surfaces and mating surfaces of parts.
