PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EFS00282

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:
q 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.
q 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.
q 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.

ADJUSTMENT
1. Insert a deep-well socket wrench to rotate self-locking nut to
loosen cable sufficiently. Then, after returning pedal completely, PB
adjust the clearance of rear shoes.
2. Remove road wheels.
3. Using a wheel nut, fix the disc to hub preventing it from tilting. G

4. Remove adjuster hole plug installed on disc. Using a flat-bladed-
screwdriver, turn disc to clock wise as shown in figure until disc
is locked. After locking, turn adjuster to opposite direction by 5 J
or 6 notches.
5. Rotate disc to make sure that there is no drag. Then install
adjuster hole plug.
K
6. After adjusting the clearance of rear shoes, with no drag on rear
brake, adjust cable as follows:
a. Operate pedal 10 or more times with the force of 294 N (30 kg,
L
66 lb).
SBR046C
b. Depress pedal until a deep-well socket can be inserted. Insert
deep-well socket, and rotate self-locking nut to adjust pedal stroke.
M
CAUTION:
Do not reuse self-locking nut after removing it.
c. After operating pedal 3 to 4 times with the force of 196 N (20 kg, 44 lb), make sure that pedal stroke is
within specified value.
d. With pedal completely returned, make sure that there is no drag on rear brake.

drum brake.
6. Repeat steps 1 through 5 three times and then repeat only step 5 one more time.
7. After the break-in procedure, check pedal stroke of parking brake. If it is out of the specification, adjust
again.
