Nissan Sentra Service Manual: Precaution
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. Information necessary to service the system safely is
included in the SR 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 SR 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 three minutes before performing any service.
Procedure without Cowl Top Cover
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

Handling for Adhesive and Primer
- Do not use an adhesive which is past its usable date. Shelf life of this
product is limited to six months after
the date of manufacture. Carefully adhere to the expiration or manufacture
date printed on the box.
- Keep primers and adhesive in a cool, dry place. Ideally, they should be
stored in a refrigerator.
- Open the seal of the primer and adhesive just before application.
Discard the remainder
- Before application, be sure to shake the primer container to stir the
contents. If any floating material is found,
do not use it.
- If any primer or adhesive contacts the skin, wipe it off with gasoline
or equivalent and wash the skin with
soap.
- When using primer and adhesive, always observe the precautions in the
instruction manual.
Precaution for Work

or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
- When removing (disengaging) components with a screwdriver or similar
tool, be sure to wrap the component
with a shop cloth or vinyl tape to protect it.
- Protect the removed parts with a shop cloth and prevent them from being
dropped.
- Replace a deformed or damaged clip.
- If a part is specified as a non-reusable part, always replace it with a
new one.
- Be sure to tighten bolts and nuts securely to the specified torque.

properly.
