BASIC INSPECTION 1: BRAKE FLUID LEVEL, LEAK INSPECTION AND BRAKE PAD
1. Check fluid level in brake reservoir tank. If fluid level is low, refill brake fluid. Refer to BR-9, "CHECKING
BRAKE FLUID LEVEL" .
2. Check for leakage in brake tubes or hoses and around ABS actuator and electric unit (control unit). If
there is leaking or seeping fluid, check the following items.

If the brake tube connections at ABS actuator and electric unit (control unit) are loose, tighten flare nuts
to the specified torque. Then inspect again and confirm that there is no leakage.

If flare nuts or screws of ABS actuator and electric unit (control unit) are damaged and loose, replace
damaged parts. Then inspect again and confirm that there is no leakage.

If there is leakage at any location other than ABS actuator and electric unit (control unit) connections,
wipe away leakage with clean cloth. Then inspect again and confirm that there is no leakage.

If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage with clean cloth.
Then inspect again. If there is still leakage, replace ABS actuator and electric unit (control unit).
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake disc rotor and pads.

Front disc rotor: Refer to BR-27, "DISC ROTOR INSPECTION" .

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NBS005RT
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.
Precautions for Liquid GasketNBS004QK
REMOVAL OF LIQUID GASKET SEALING

After removing mounting nuts and bolts, separate the mating
surface using the seal cutter (SST) and remove old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.

Tap the seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.

In areas where seal cutter is difficult to use, use a plastic ham-
mer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as a screwdriver
is used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove old liquid gasket adhering to the liquid
gasket application surface and the mating surface.

Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.

InspectionNBS004QQ
LEVEL CHECK

Check if the reservoir tank engine coolant level is within the
“MIN” to “MAX” when the engine is cool.

Adjust the engine coolant level as necessary.
LEAK CHECK

To check for leaks, apply pressure to the cooling system with the
radiator cap tester (commercial service tool) (A) and radiator
cap tester adapter (commercial service tool) (B).
WARNING:
Do not remove radiator cap when engine is hot. Serious
burns could occur from high-pressure engine coolant
escaping from radiator.
CAUTION:
Higher test pressure than specified may cause radiator
damage.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.

If anything is found, repair or replace damaged parts.
Changing Engine CoolantNBS004QR
WARNING:

To avoid being scalded, do not change engine coolant when the engine is hot.

Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.
DRAINING ENGINE COOLANT
1. Remove engine room cover (RH and LH). Refer to EM-15, "ENGINE ROOM COVER" .
2. Remove air duct (inlet). Refer to EM-19, "
AIR CLEANER AND AIR DUCT" .
3. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to EM-125, "
DISASSEMBLY" .
