Adjustment
This mode is used to correct difference between actual turning angle of a
vehicle and turning angle of the vehicle mark on the display.
Speed
Calibration Under ordinary conditions, the navigation system distance measuring func-
tion will automatically compensate for minute decreases in wheel and tire
diameter caused by tire wear or low-pressure. Speed Calibration can im-
mediately restore system accuracy in cases such as when distance calibra-
tion is needed because of the use of tire chains.

SQUEAK AND RATTLE TROUBLE DIAGNOSIS
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate 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 model, drive position on A/T model).
6) 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 v ehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, chec k ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follo w 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 pi npoint 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 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 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 push/pull the component with excessive force, otherwise the noise will only be eliminated tem-
porarily.
 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 BL-9, "
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 loos ening 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 av ailable through your authorized Nissan Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
Always check with the Parts Departm ent 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.

HOOD
6. Remove the grommet on the dashboard, and pull the hood lock cable toward the passenger room.CAUTION:
While pulling, be careful not to damage (p eeling) the outside of the hood lock cable.
INSTALLATION
1. Pull the hood lock cable through the panel hole to the engine room.
Be careful not to bend the cable too much, keeping the radius
100 mm (3.94 in) or more.
2. Make sure the cable is not offset from the positioning grommet, and push the grommet into the panel hole securely.
3. Apply the sealant to the grommet (at * mark) properly.
4. Install the cable securely to the lock.
5. After installing, check the hood lock adjustment and hood opener operation.
Hood Lock Control InspectionINFOID:0000000001327786
CAUTION:
If the hood lock cable is bent or deformed, replace it.
1. Make sure that the hood lock secondary latch is properlyengaged with the secondary striker with hood's own weight.
2. Make sure that the hood lock primary latch is securely engaged with the hood striker with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height.
CAUTION:
Do not drop hood from a he ight of 300 mm (11.81 in) or
more.
3. When pulling hood opener lever gently, make sure that front end of the hood rises by approximately 20 mm (0.79 in) and that hood striker and hood lock primary latch are disengaged. Also make sure that hood
opener returns to the original position.
