Nissan Maxima Service and Repair Manual: Precaution
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 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 3 minutes before performing any service.
Precaution for Procedure without Cowl Top Cover

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake System
- Always use recommended brake fluid. Refer to MA-15, "FOR USA AND CANADA
: Fluids and Lubricants"
(for United States and Canada) or MA-16, "FOR MEXICO : Fluids and
Lubricants" (for Mexico).
- Do not reuse drained brake fluid.
- Do not spill or splash brake fluid on painted surfaces. Brake
fluid may seriously damage paint. Wipe it off
immediately and wash with water if it gets on a painted surface.
- Always confirm the specified tightening torque when installing the
brake pipes.
- After pressing the brake pedal more deeply or harder than normal
driving, such as air bleeding, check each
item of brake pedal. Adjust brake pedal if it is outside the standard value.
- Do not use mineral oils such as gasoline or light oil to clean.
They may damage rubber parts and cause
improper operation.
- Always loosen the brake tube flare nut with a flare nut wrench.

- Tighten the brake tube flare nut to the specified torque with a crowfoot
(A) and torque wrench (B).
- Always connect the battery terminal when moving the vehicle.
- Turn the ignition switch OFF and disconnect the ABS actuator and
electric unit (control unit) harness connector or the battery negative
terminal before performing the work.
- Check that no brake fluid leakage is present after replacing the
parts.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
