Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003809633
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 AIRBAG” and “SEAT BELT” 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 AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

INFOID:0000000003890160
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 AIRBAG” and
“SEAT BELT” 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 AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

connectors.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003890161
NOTE:
 Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.

BRAKE FLUID
InspectionINFOID:0000000003811173
BRAKE FLUID LEVEL
 Check that the fluid level in the sub tank is within the specified
range (MAX – MIN lines).
 Visually check for any brake fluid leakage around the sub tank,
reservoir tank and hose.
 Check the brake system for any leakage if the fluid level is
extremely low (lower than MIN).
 Check the brake system for fluid leakage if the warning lamp
remains illuminated even after the parking brake is released.
BRAKE LINE
1. Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged
parts.
2. Check for fluid leakage by fully depressing brake pedal while
engine is running.
CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
DrainingINFOID:0000000003811174
CAUTION:
 Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with water if it gets on a painted surface.
 Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-
nector or the battery negative terminal before draining.
1. Connect a vinyl tube to the bleed valve.
2. Depress the brake pedal and loosen the bleeder valve to gradu-
ally discharge brake fluid.
RefillingINFOID:0000000003811175
CAUTION:
Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) connec-
tor or the battery negative terminal before refilling.
1. Check that there is no foreign material in the sub tank, and refill with new brake fluid.
CAUTION:
Never reuse drained brake fluid.

2. Loosen the bleeder valve, slowly depress the brake pedal to the full stroke, and then release the pedal.
Repeat this operation at intervals of 2 or 3 seconds until all brake fluid is discharged. Then close the
bleeder valve with the brake pedal depressed. Repeat the same work on each wheel.
3. Perform the air bleeding. Refer to BR-10, "
Bleeding Brake System".
Bleeding Brake SystemINFOID:0000000003811176
CAUTION:
 Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-
nector or the battery negative terminal before performing the work.
 Monitor the fluid level in the sub tank during the air bleeding.
 Always use new brake fluid for refilling. Never reuse the drained brake fluid.
1. Connect a vinyl tube to the bleeder valve of the rear right brake.
2. Fully depress the brake pedal 4 to 5 times.
3. Loosen the bleeder valve and bleed air with the brake pedal depressed, and then quickly tighten the
bleeder valve.
4. Repeat steps 2 and 3 until all of the air is out of the brake line.
5. Tighten the bleeder valve to the specified torque.
 Front disc brake: refer to BR-34, "
BRAKE CALIPER ASSEMBLY : Exploded View".
 Rear disc brake: refer to BR-40, "
BRAKE CALIPER ASSEMBLY : Exploded View".
6. Perform steps 1 to 5 for the rear right brake → front left brake → rear left brake → and front right brake in
order.
7. Check that the fluid level in the sub tank is within the specified range after air bleeding. Refer to BR-9,
"Inspection".
