PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001716907
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 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 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.
Precaution for Brake SystemINFOID:0000000001716908
 Refill using recommended brake fluid. Refer to MA-19, "Fluids and Lubricants".
 Never reuse drained brake fluid.
 Be careful not to splash brake fluid on painted surface of body. If brake fluid is splashed on painted surfaces
of body immediately wipe it off with cloth and then wash it away with water.
 To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
 Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
 Use a flare nut wrench when removing a brake tube and use a
flare nut torque wrench when installing a brake tube.
 When installing brake tubes and hoses, be sure to check torque.
 Before working, turn ignition switch OFF and disconnect connec-
tors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
 Burnish the new braking surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage. Refer toBR-26, "
Brake Burnishing" .

NOTE:
LHD shown RHD similar.
CAUTION:
 All tubes and hoses must be free from excessive bending, twisting and pulling.
 Make sure there is no interference with other parts when turning steering both clockwise and coun-
terclockwise.
 Brake tubes and hoses are an important safety part. Always disassemble the parts and retighten
their fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part
is detected.
 Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe them with cloth and then wash it away with
water.
 Do not bend or twist brake hose sharply, or strongly pull it.
 When removing components, cover brake line connections so that dirt, dust, or other foreign mat-
ters do not get in.
 Refill using recommended brake fluid. Refer to MA-19, "
Fluids and Lubricants".
 Never reuse drained brake fluid.
