PRECAUTIONS < SERVICE INFORMATION > SERVICE INFORMATION PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000004277377 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 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 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 Precaution INFOID:0000000004277378 • When removing or disassembling any part, be careful not to damage or deform it Protect parts which may get in the way with cloth • When removing parts with a screwdriver or other tool, protect parts by wrapping the tool with vinyl or tape • Keep removed parts protected with cloth • If a clip is deformed or damaged, replace it • If an unreusable part is removed, replace it with a new one • Tighten bolts and nuts firmly to the specified torque • After re-assembly has been completed, make sure each part functions correctly • Remove stains in the following way - Water-soluble stains: Dip a cloth in warm water, and squeeze tightly After wiping the stain, wipe with a soft dry cloth - Oil stain: Dissolve a synthetic detergent in warm water (density of to 3% or less), dip the cloth, then clean off the stain with the cloth Next, dip the soft cloth in fresh water, and then squeeze it tightly Then clean off the detergent completely Then wipe the area with a soft dry cloth • Do not use any organic solvent, such as thinner or benzine

DIAGNOSIS Work Flow INFOID:0000000004277381 SBT842 CUSTOMER INTERVIEW Interview the customer, if possible, to determine the conditions that exist when the noise occurs Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any customer's comments; refer to EI-8, "Diagnostic Worksheet" This information is necessary to duplicate the conditions that exist when the noise occurs • The customer may not be able to provide a detailed description 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 one noise in the vehicle, be sure to diagnose and repair the noise that the customer 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 so the customer, service adviser and technician are all speaking the same language when defining the noise - Squeak — (Like 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 floor) 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 characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing clip or fastener/incorrect 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 gentle contacting of light materials/loose 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 bumblebee) 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 • Weather conditions, especially humidity and temperature, may have a great effect on noise level 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 Worksheet regarding the conditions or location of the noise This information can be used to duplicate the same conditions when you confirm the repair Revision: October 2008 EI-4 2009 Quest SQUEAK AND RATTLE TROUBLE DIAGNOSIS < SERVICE INFORMATION > 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: • Close a door • Tap or push/pull around the area where the noise appears to be coming from • Rev the engine • Use a floor jack to recreate vehicle “twist” • At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model) • Raise the vehicle on a hoist and hit a tire with a rubber hammer • Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs • If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the vehicle body A B C D 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 E LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE Narrow down the noise to a general area To help pinpoint the source of the noise, use a listening tool F (Chassis Ear: J-39570, Engine Ear: J-39565 and mechanics stethoscope) Narrow down the noise to a more specific area and identify the cause of the noise by: G • Removing the components in the area that you suspect the noise is coming from Do not use too much force when removing clips and fasteners, otherwise clips and fasteners 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 H Do not tap or push/pull the component with excessive force, 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 EI 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 EI-6, "Generic Squeak and Rattle Troubleshooting" J 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 urethane 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 Always check with the Parts Department

CONFIRM THE REPAIR Confirm that the cause of a noise is repaired by test driving the vehicle Operate the vehicle under the same conditions as when the noise originally occurred Refer to the notes on the Diagnostic Worksheet Generic Squeak and Rattle Troubleshooting INFOID:0000000004277382 Refer to Table of Contents for specific component removal and installation information INSTRUMENT PANEL Most incidents are caused by contact and movement between: The cluster lid A and instrument panel Acrylic lens and combination meter housing Instrument panel to front pillar garnish Instrument panel to windshield Instrument panel mounting pins Wiring harnesses behind the combination meter A/C defroster duct and duct joint These incidents can usually be located by tapping or moving the components to duplicate the noise or by pressing on the components while driving to stop the noise Most of these incidents can be repaired by applying felt cloth tape or silicone spray (in hard to reach areas) Urethane pads can be used to insulate wiring harness CAUTION: Do not use silicone spray to isolate a squeak or rattle If you saturate the area with silicone, you will not be able to recheck the repair CENTER CONSOLE Components to pay attention to include: Shifter assembly cover to finisher A/C control unit and upper/lower cluster lid C 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: Finisher and inner panel making a slapping noise Inside handle escutcheon to door finisher Wiring harnesses tapping 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 these incidents You can usually insulate the areas with felt cloth tape or insulator foam blocks from the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise BACK DOOR Luggage compartment noises are often caused by a loose jack or loose items put into the luggage compartment by the owner In addition look for: Back door bumpers out of adjustment Back door striker out of adjustment A loose license plate or bracket Revision: October 2008 EI-6 2009 Quest SQUEAK AND RATTLE TROUBLE DIAGNOSIS < SERVICE INFORMATION > Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causing the noise A SUNROOF/HEADLINER Noises in the sunroof/headliner area can often be traced to one of the following: Sunroof lid, rail, linkage or seals making a rattle or light knocking noise Sunvisor shaft shaking in the holder Front or rear windshield touching headliner 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 OVERHEAD CONSOLE (FRONT AND REAR) B C D Overhead console noises are often caused by the console panel clips not being engaged correctly Most of these incidents are repaired by pushing up on the console at the clip locations until the clips engage In addition look for: Loose harness or harness connectors Front console map/reading lamp lens loose Loose screws at console attachment points E F SEATS When isolating seat noises it is important to note the position the seat is in and the load placed on the seat when the noise is present These conditions should be duplicated when verifying and isolating the cause of G the noise Cause of seat noise include: Headrest rods and holders H A squeak between the seat pad cushion and frame The rear seatback lock and bracket These noises can be isolated by moving or pressing on the suspected components while duplicating the con- EI ditions under which the noise occurs Most of these incidents can be repaired by repositioning the component or applying urethane tape to the contact area J UNDERHOOD Some interior noises may be caused by components under the hood or on the engine wall The noise is then transmitted into the passenger compartment Causes of transmitted underhood noises include: Any component mounted to the engine wall Components that pass through the engine wall Engine wall mounts and connectors Loose radiator mounting pins Hood bumpers out of adjustment Hood striker out of adjustment These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle 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 changed to isolate the noise Repairs can usually be made by moving, adjusting, securing, or insulating the component causing the noise K L M N O P Revision: October 2008 EI-7 2009 Quest

running at low or medium speed, the power valve is fully closed Under this condition, the effective suction port length is equivalent to the total length of the intake manifold collector's suction port including the intake valve This long suction port provides increased air intake which results in improved suction efficiency and higher torque generation The surge tank and one-way valve are provided When engine is running at high speed, the ECM sends the signal to the VIAS control solenoid valve This signal introduces the intake manifold vacuum into the power valve actuator and therefore opens the power valve to two suction passages together in the collector Under this condition, the effective port length is equivalent to the length of the suction port provided independently for each cylinder This shortened port length results in enhanced engine output with reduced suction resistance under high speeds K L M N COMPONENT DESCRIPTION Power Valve The power valve is installed in intake manifold collector and used to control the suction passage of the variable induction air control system It is set in the fully closed or fully opened position by the power valve actuator (1) operated
