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

NFS00066

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.

Inspection and Adjustment (Pedal Type)

NFS00067

INSPECTION

●

While operating parking brake pedal with a force of 200 N (20 kg, 45 lb). Make sure that the parking brake
pedal stroke is within the range of the specified number of notches.

●

Make sure that brake warning lamp comes on when parking brake pedal is operated within one notch.

ADJUSTMENT

●

To perform adjustment operations, remove tires from vehicle with power tool. Using a wheel nut, fix disc
rotor to wheel hub preventing it from tilting.

1.

Insert a deep socket wrench to rotate adjusting nut to loosen
cable sufficiently. Then, after releasing parking brake pedal com-
pletely, adjust the clearance of rear shoes.

2.

Remove adjuster hole plug installed on the disc rotor. Using a
flat-bladed screwdriver, turn adjuster in direction “A” as shown in
the figure until adjuster is locked. After locking, turn adjuster to
the opposite direction by 5 or 6 notches.

3.

Rotate disc rotor to make sure that there is no drag. Then install
adjuster hole plug.

4.

After adjusting the clearance of rear shoes, with no drag on the
rear brake, adjust cable as follows:

a.

Operate parking brake pedal 10 or more times with a force of
490 N (50 kg, 110 lb).

b.

Depress parking brake pedal until a deep socket can be
inserted. Insert the deep socket, and rotate adjusting nut to adjust a parking brake pedal stroke to speci-
fied notches.

CAUTION:

Do not reuse adjusting nut after removing it.

c.

After operating parking brake pedal 3 to 4 times with a force of 200 N (20 kg, 45 lb), make sure that the
parking brake pedal stroke is within the specified number of notches.

d.

With parking brake pedal completely returned, make sure that there is no drag on the rear brake.

Inspection and Adjustment (Lever Type)

NFS00068

INSPECTION

●

While operating parking brake lever with a force of 196 N (20 kg,
44lb). Make sure that the parking brake lever stroke is within the
range of the specified number of notches.

●

Make sure that brake warning lamp comes on when parking
brake lever is operated with in one notch.

Number of notches

: 2 – 3 notches

1.

Insert a deep socket wrench to rotate adjusting nut to loosen
cable sufficiently. Then, after releasing the parking brake lever
completely, adjust the clearance of rear shoes.

2.

Remove adjuster hole plug installed on the disc rotor. Using a
flat-bladed screwdriver, turn adjuster in direction “A” as shown in
the figure until adjuster is locked. After locking, turn adjuster to
the opposite direction by 5 or 6 notches.

3.

Rotate disc rotor to make sure that there is no drag. Then install
adjuster hole plug.

4.

After adjusting the clearance of rear shoes, with no drag on the
rear brake, adjust cable as follows:

a.

Operate parking brake lever 10 or more times with a force of 294
N (30 kg, 66 lb).

b.

Operate parking brake lever until a deep socket can be inserted.
Insert deep socket, and rotate adjusting nut to adjust a parking brake lever stroke to the specified notches.

CAUTION:

Do not reuse adjusting nut after removing it.

c.

After operating parking brake lever 3 to 4 times with a force of 196 N (20 kg, 44 lb), make sure that the
