PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612923
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 whether 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 inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent 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 Brake SystemINFOID:0000000001327654
 Recommended fluid is brake fluid “DOT 3”. Refer to MA-9.
 Do not reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off and flush area with water immediately.
 Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause improper operation.
 Using a flare nut crowfoot and torque wrench, securely tighten brake tube flare nuts.
 Brake system is an important safe ty part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction is
detected, replace part with a new one.
 Before working, turn ignition switch OFF and disconnect electrical
connectors of ABS actuator and elec tric unit (control unit) or bat-
tery negative terminal.
 When installing brake piping, be sure to check torque.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precaution for Brake ControlINFOID:0000000001327655
 During VDC/TCS/ABS operation, brake pedal lightly vi brates and a mechanical noise may be heard. This is
normal.
 Just after starting vehicle after turning ignition switch ON, brake pedal may vibrate or motor operating noise
may be heard from engine room. This is a normal status of operation check.
 Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
 When an error is indicated by ABS or another warning lamp, collect all necessary information from customer
(what symptoms are present under what conditions) and check for simple causes before starting diagnostic
servicing. Besides electrical system inspection, c heck booster operation, brake fluid level, and fluid leaks.
 If tire size and type are used in an improper combinat ion, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
 If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, VDC/TCS/ABS
function may have a malfunction or error.
 If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

PRECAUTIONS
3. Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
4. Apply liquid gasket without breaks to the specified location with the specified dimensions.
 If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.
 As for the bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.
 Within five minutes of liquid gasket application, install the mat-
ing component.
 If liquid gasket protrudes, wipe it off immediately.
 Do not retighten after mounting bolts and nuts the installation.
 After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

INSPECTION AFTER INSTALLATION
 Check for leaks of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-10, "
Inspection".
 Start and warm up the engine. Visually make sure t hat there is no leaks of engine coolant and A/T fluid.
Checking Radiator CapINFOID:0000000001325849
 Check valve seat of radiator cap.
- Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
- Check if valve seat has no soil and damage.
