PRECAUTIONS

PRECAUTIONS PFP:00001

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

AIS000I2

The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used alon g with a front seat belt, helps to redu ce th e risk or se verit y of i njury to the driv er and front passenge r for ce rtain types of collision. This system includes sea t 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 Manual.

WARNING:

● To avoid rendering the SRS inopera tive, whi ch could increa se the risk of perso nal injury or dea th

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, inc luding incorrect removal and installation of the SRS, can lead to per-

sonal injury ca use d by unintentional ac tiv atio n of the system. F or r e mo va l o f Spi ral Cable and Air Bag Module, see the SRS section.

● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed to in this

Service Manual. SRS wiring harnesses can be id entified by yellow and/or orange harnesses or harness connectors.

Service Notice AIS000I1

● When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent

scratches.

● Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to oil or

damage them.

● Apply sealing compound where necessary when installing parts.

● When applying sealing compound, be careful that the sealing compound does not protrude from parts.

● When replacing a ny metal parts (for e xample body oute r panel, mem bers, et c.), be sure to take rust pre-

vention measures.

Precautions for Battery Service AIS001PC

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between t h e wi nd ow ed ge an d th e v eh ic le wh en the do or is ope ne d/ cl o sed. Dur i n g nor ma l op era ti on, t he window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.

Precautions for Work AIS000I3

● When removing or disassembling each component, be careful not to damage or deform it. If a component

may be subject to interference, be sure to protect it with a shop cloth.

● When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the compo-

nent with a shop cloth or vinyl tape to protec t it.

● Protect the removed part s with a shop cloth and keep them.

● Replace a deformed or damaged clip.

● If a part is s p ecified as a no n-reusable part, always r eplace it with new one.

● Be sure to tighten bolts and nuts securely to the specified torque.

● After re-installation is completed, be sure to check that each part works normally.

● Follow the steps below to clean components.

– Water soluble foul: Dip a soft cloth into lukewarm w ater, and wring the water out of the clot h to wipe the

fouled area. Then rub with a soft and dry cloth.

– Oily foul: Dip a soft cloth i nto l ukewa rm wat er with mi ld det erg ent (c oncen trat ion : wit hin 2 t o 3%), and wi pe

the fouled area. Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub with a soft and dry cloth.

CUSTOMER INTERVIEW

Interview the cus to me r if po ss ib le , to de t ermi n e th e co nd iti on s th at exi st whe n th e no is e occu r s. Use th e D iagnostic Worksheet durin g the interview to docum ent the facts and conditio ns when the noise occu rs and any customer's comments; refer to SE-10, " conditions that exist when the noise occu rs.

● The customer may not be able to p rovide a detailed d escription or the location of the noise. Attempt to

obtain all the facts and conditions that exist when the noise occurs (or does not occur).

● If there is more than on e noi se in the v ehic le, b e sure to diag nose and re pair the n oise that the cu stom er

is concerned about. This can be accomplished by test driving the vehicle with the customer.

● After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics

are provided s o the cus tomer, service adviser and techni cian are al l speaking the same language w hen defining the noise.

● Squeak —(Li ke tennis shoes on a clean floor)

Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping

● Creak—(Like walking on an old wooden floo r)

Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch dependent on materials/often brought on by activity.

● Rattle—(Like shaking a baby rattle)

Rattle charac teristic s inclu de the fast repe ated c ontact/vibrat ion or simila r moveme nt/loose parts/missi ng clip or fastener/incorrec t clearance.

● Knock —(Like a knock on a door)

Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.

● Tick—(Like a clock second hand)

Tick characteristics include ge ntle contacting of light materials/l oose components/can be caused by driver action or road conditions.

● Thump—(Heavy, muffled knock noise)

Thump characteristics include softer knock/dead sound often brought on by activity.

● Buzz—(Like a bumble bee)

Buzz characteristics include high frequency rattle/firm contact .

● Often the degree of acceptable noise level will vary depending upon the person. A noise that you may

judge as acceptable may be very irritating to the customer.

● Weath er conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSES

DUPLICATE THE NOISE AND TEST DRIVE

If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on the Diagnostic Works heet regarding the co nditions or locatio n of the noise. This in formation can be used to duplicate the same conditions when you confirm the repair. If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following:

1) Close a door.

2) Tap or push/pull around the area where the noise appears to be coming from.

3) Rev the engine.

4) Use a floor jack to recreate vehicle “twist”.

5) At idle, apply engine load (electrical load, half-clutch on M/T models, drive position on A/T models).

6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.

● Drive the vehicl e an d att em pt to dup li ca te th e co nd iti on s th e cust om er states exist whe n th e no is e oc cu rs.

● If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the

vehicle body.

CHECK RELATED SERVICE BULLETINS

After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related to that concern or symptom. If a TSB relates to the symptom, follow the procedure to repair the noise.

LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE

1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool (Chassis Ear: J-39570, Engine Ear and mechanics stethoscope).

2. Narrow down the noise to a more specific area and identify the cause of the noise by:

● removing the components i n the area that you suspect the noise is coming from .

Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be broken or lost during the repair, resulting in the creation of new noise.

● tapping or pushing/pulling the component that you suspect is causing the noise.

Do not tap or pu sh/pull the c omponent with excessive fo rce, otherwise the noise will be eliminated only temporarily.

● feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the

noise.

● placing a piece of paper between components that you suspect are causing the noise.

● looking for loose components and contact marks.

Refer to SE-8, "

Generic Squeak and Rattle Troubleshooting" .

REPAIR THE CAUSE

● If the cause is a loose component, tighten the component securely.

● If the cause is insufficient clearance between components:

– separate components by repositioning or loosening and retightening the component, if possible. – insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or ure-

thane tape. A Nissan Squeak and Rattle Kit (J-43980) is available through your authorized Nissan Parts Department.

CAUTION:

Do not use excessive force as many components are constructed of plastic and may be damaged. NOTE:

Always check with the Parts Department for the latest parts information. The following materials are contained in the Nissan Squeak and Rattle Kit (J-43980). Each item can be ordered separately as needed.

CONFIRM THE REP AIR

Confirm that the c ause of a n oise is repai red by test dr iving the ve hicle. Op erate the ve hicle und er the same conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.

Generic Squeak and Rattle Troubleshooting AIS0066N

Refer to Table of Contents for specific component removal and installation information.

INSTRUMENT PANEL

Most incidents are caused by contact and movement between:

1. The cluster lid A and instr ument panel

2. Acrylic lens and combination meter housing

3. Instrument panel to front pillar ga rni sh

4. Instrument panel to windshield

5. Instrument panel mounting pins

6. Wiring harnesses behind the combination meter

7. A/C defros ter duct and duct joint These incide nts can usually b e located by tapping or moving the com ponents to duplicate the noise o r by

pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silico n spray (in h ard to reac h areas ). Uret hane pads can be used to insul ate wiring harness.

CAUTION:

Do not use silicone s pray to isolate a s queak or rattle. If you saturate the ar ea with silicone , you will not be able to recheck the repair.

CENTER CONSOLE

Components to pay attention to include:

1. Shifter assembly cover to finisher

2. A/C control unit and cluster lid C

3. Wiring harnesses behind audio and A/C control unit The instrument panel repair and isolation procedures also apply to the center console.

DOORS

Pay attention to the:

1. Finisher and inner panel making a slapping noise

2. Inside handle escutcheon to door finisher

3. Wiring harnesses tapping

4. Door striker out of alignment causing a popping noise on starts and stops Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate

many of thes e incidents. You can usuall y insulat e the areas with fel t cloth tape o r insulator foam bloc ks from the Nissan Squeak and Rattle Kit (J-43980) to repair the noise.

SQUEAK AND RATTLE TROUBLE DIAGNOSES

TRUNK

Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner. In addition look for:

1. Trunk lid dumpers out of adjustment

2. Trunk lid striker out of adjustment

3. The trunk lid torsio n ba rs kn oc king together

4. A loose licen s e pla te or bra ck et

Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causing the noise.

SUNROOF/HEADLINING

Noises in the sunroof/headlining area can often be traced to one of the following:

1. Sunroof lid, r ail, linkage or seals making a rat tle or light knocking noise

2. Sunvisor shaft shaking in the holder

3. Front or rear windshield touching headlining and squeaking

Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these incidents. Repairs usually consist of insulating with felt cloth tape.

SEATS

When isolati ng sea t noise i t's im por t ant to no te th e posi tion th e seat is in a nd the load place d on the sea t when the noise is present. These con ditions should be duplicated when verifying and isolating the cause of the noise. Cause of seat noise include:

1. Headrest rods and holder

2. A squeak betwe e n the seat pad cushion and f rame

3. The rear seatback lock and bracket

These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under whi ch the no is e o cc urs . M os t of these incidents can be repaired by repo si tio ni ng the co m ponent or applying ur ethane tape to the contact area.

UNDERHOOD

Some interior noise may be caused by components und er the hood or on the engine wall. The noise is then transmitted into the passenger compartment. Causes of transmitted underhood noise inc lude:

1. Any component mounted to the engine wall

2. Components that pass through the engi ne wall

3. Engine wall mounts and connectors

4. Loose radiator mounting pins

5. Hood bumpers out of adjustment

6. Hood striker out of adjustment

These noises can be difficult to is olate since they cann ot be reached fro m the int erior of th e vehic le. The best method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM or load can be chan ged to isola te the noise . Repairs can usua lly be made by moving, adjusting, securing, or insulating the component causing the noise.
