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.
Precaution for Trouble Diagnosis
Av communication system
- Do not apply voltage of 7.0 V or higher to the measurement terminals.
- Use the tester with its open terminal voltage being 7.0 V or less.
- Be sure to turn ignition switch OFF and disconnect the battery cable
from the negative terminal before
checking the circuit.
Precaution for Harness Repair
Av communication system
- Solder the repaired parts, and wrap with tape. [Frays of twisted line
must be within 110 mm (4.33 in).]

- Do not perform bypass wire connections for the repair parts. (The
spliced wire will become separated and the characteristics of
twisted line will be lost.)

Precaution for work
- When removing or disassembling each component, be careful not to damage
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.
- After installation is complete, be sure to check that each part works
properly.
- Follow the steps below to clean components:
Water soluble dirt:
- Dip a soft cloth into lukewarm water, wring the water out of the cloth
and wipe the dirty area.
- Then rub with a soft, dry cloth.
Oily dirt:
- Dip a soft cloth into lukewarm water with mild detergent (concentration:
within 2 to 3%) and wipe the dirty
area.
- Then dip a cloth into fresh water, wring the water out of the cloth and
wipe the detergent off.
- Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.
