PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010309911
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 har-
ness 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 Igni-
tion 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 Procedure without Cowl Top Cover
INFOID:0000000009755979
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 Brake System
INFOID:0000000009755980
WARNING:
Clean any dust from the front brake and rear brake with a vacuum dust collector. Do not blow with
compressed air.
• Brake fluid: Refer to
MA-11, "Fluids and Lubricants"
.
• Do not reuse drained brake fluid.
• Do not spill or splash brake fluid on painted surfaces. Brake fluid may damage paint. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• 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.
• Always clean with new brake fluid when cleaning the brake caliper and other components.
• Do not use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and cause
improper operation.

PRECAUTIONS
• Always loosen the brake tube flare nut with a flare nut wrench.
• Tighten the brake tube flare nut to the specified torque with a crow-
foot (A) and torque wrench (B).
• Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction is
detected, replace part with a new one.
• Always connect the battery terminals when moving the vehicle.
• Turn the ignition switch OFF and disconnect the hydraulic booster
assembly harness connector or the battery negative terminal
before performing the work.
• Check that no brake fluid leakage is present after replacing the
parts.
• Burnish the brake contact surfaces after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
