Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001691368
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 SRS 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 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 harness connec-
tors.
Precaution for Brake SystemINFOID:0000000001691369
 Recommended fluid is Genuine NISSAN Fluid, DOT 3 or DOT 4 (US FMVSS No. 116).
 Do not reuse the drained brake fluid.
 Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off and
flush area with water immediately.
 Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.
 Using a flare nut torque wrench, securely tighten brake tube flare
nuts.
 Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble malfunctioning parts. If any mal-
functioning part is found, replace the part with a new one.
 Before working, turn ignition switch OFF and disconnect connec-
tors for ABS actuator and electric unit or battery terminals.
 When installing brake piping, be sure to check tightening torque.
Precaution for Brake ControlINFOID:0000000001691370
 During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
 When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noise may be
heard from engine compartment. This is a normal status of operation check.
 Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
 When an error is indicated by ABS or another warning lamp, collect all necessary information from the cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting diag-
nostic servicing. Besides the electrical system inspection, check booster operation, brake fluid level, and oil
leaks.
 If tyre size and type are used in an improper combination, or brake pads are not Genuine Nissan parts, stop-
ping distance or steering stability may deteriorate.
 If there is a radio, antenna, or antenna lead-in wire (including wiring) near the control unit, ABS system may
malfunction or return an error.
 If aftermarket parts (e.g. car stereo equipment, CD player) have been installed, check electrical harnesses
for pinches, open, and improper wiring.
