SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612918
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001612920
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake SystemINFOID:0000000001327604
 Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
 Recommended fluid is brake fluid “DOT 3”. MA-9, "
Fluids and Lubricants".
 Do not reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas.
 To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
 Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
 Use a flare nut crowfoot and torque wrench when installing brake
tube.
 When installing brake piping, be sure to check torque.
 Before working, turn ignition switch OFF and disconnect connec- tors for ABS actuator and electric unit (control unit) or battery neg-
ative terminal.
 Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to BR-23, "
Brake Burnishing Procedure" (Front disc brake),
BR-29, "
Brake Burnishing Procedure" (Rear disc brake).
WARNING:
 Clean brake pads and shoes with a waste cl oth, then clean with a dust collector.

LEVEL CHECK
 Make sure the fluid level in reservoir tank is within the standard(between MAX and MIN lines).
 Visually check around reservoir tank for fluid leakage.
 If fluid level is excessively low, check brake system for leakage.
 Release parking brake pedal and see if brake warning lamp goes off. If not, check brake system for fluid leakage.
Drain and RefillINFOID:0000000001327611
CAUTION:
 Refill with new brake fluid “DOT3”.
 Do not reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of bo dy, immediately wipe it off and them wash it away with water
immediately.
 Before working, disconnect connectors of ABS actua tor and electric unit (control unit) or battery
negative terminal.
1. Connect a vinyl tube to each bleed valve.
2. Depress brake pedal, loosen each bleed valve, and gradually remove brake fluid.
3. Make sure there is no foreign material in reservoir tank, and refill with new brake fluid.
4. Rest foot on brake pedal. Loosen bleed valve. Slowly depress pedal until it stops. Tighten bl eed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.
5. Bleed Air. Refer to BR-8, "
Bleeding Brake System".

 Carefully monitor brake fluid level in reservoir tank during bleeding operation.
 Refill with new brake fluid “DOT 3”. Make sure it is at least half
way at all times while bleeding air out of system.
 Place a container under master cylinder not to spill brake fluid.
 Turn ignition switch OFF and disconnect ABS actuator and
electric unit (control unit) or battery negative terminal.
 Bleed air in the following order. Right rear brake → Left front
brake → Left rear brake → Right front brake
1. Connect a transparent vinyl tube to bleed valve.
2. Fully depress brake pedal several times.
3. With brake pedal depressed, open bleed valve to release air.
4. Close bleed valve.
5. Release brake pedal slowly.
6. Repeat steps 2, through 5, until clear brake fluid comes out of bleed valve.
