PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

EFS00639

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 SRS and SB section of this Service Man-
ual.

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 per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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 for Brake System

EFS0063A

●

Recommended fluid is Genuine NISSAN Super Heavy Duty Brake Fluid or equivalent. Refer to 

MA-11,

"Fluids and Lubricants"

 .

●

Do not reuse drained brake fluid.

●

Be careful not to splash brake fluid on painted areas.

●

To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.

●

Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

●

Use flare nut wrench when removing and installing brake tube.

●

Always check tightening torque when installing brake lines.

●

Before working, turn ignition switch to OFF and disconnect con-
nectors for ABS actuator and electric unit (control unit) or battery
terminals.

●

Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to 

BR-29, "Brake Burnishing"

 .

WARNING:

●

Clean brake pads and shoes with a waste cloth, then wipe
with a dust collector.
