PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951696
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 three mi nutes before performing any service.
Precaution for Procedure without Cowl Top CoverINFOID:0000000009463955
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.
Precaution for TCM and Tran saxle Assembly ReplacementINFOID:0000000009463956
CAUTION:
• To replace TCM, refer to TM-80, "Description"
.
• To replace transaxle assembly, refer to TM-81, "Description"
.

PRECAUTIONS
General Precautions
INFOID:0000000009463957
• Turn ignition switch OFF an d disconnect the battery cable
from the negative terminal before connecting or disconnect-
ing the CVT assembly harness connector. Because battery
voltage is applied to TCM even if ignition switch is turned
OFF.
• When connecting or disconnect ing pin connectors into or
from TCM, do not damage pin terminals (bend or break).
Check that there are not any bends or breaks on TCM pin ter-
minal, when connect ing pin connectors.
• Perform TCM input/output si gnal inspection and check
whether TCM functions normally or not before replacing TCM.
Refer to TM-49, "Reference Value"
.
• Perform “DTC (Diagnostic Trouble Code) CONFIRMATION
PROCEDURE”.
If the repair is completed DTC should not be displayed in the
“DTC CONFIRMATION PROCEDURE”.
• Always use the specified brand of CVT fluid. Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubri-
cants".
• Use lint-free paper not cloth rags during work.
• Dispose of the waste oil using the methods prescribed by law, ordinance, etc. after replacing the CVT fluid.
