YES or NO

YES

>> Check the fuel level indication with vehicle on a level surface.

NO

>> GO TO 4

4.

OBSERVE FUEL GAUGE POINTER

During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES or NO

YES

>> Check the components. Refer to

MWI-35, "Component Inspection"

NORMAL OPERATING CONDITION

COMPASS
COMPASS : Description

INFOID:0000000007347510

COMPASS

• The electronic compass is highly protected from changes in most magnetic fields. However, some large

changes in magnetic fields can affect it. Some examples are (but not limited to): high tension power lines,

large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While

this does not happen very often, it is possible.

• During normal operation, the Compass Mirror will continuously update the compass calibration to adjust for

gradual changes in the vehicle's magnetic "remnant" field. If the vehicle is subjected to high magnetic influ-

ences, the compass may appear to indicate false headings, become locked, or appear that it is unable to be

calibrated. If this occurs, perform the calibration procedure.

• If at any time the compass continually displays the incorrect direction or the reading is erratic or locked, ver-

ify the correct zone variance.

Symptom Chart

Symptom

Cause

Solution / Reference

The compass display reads "C".

• Compass is not calibrated.
• Incorrect zone variance setting.
• Large change in magnetic field (Steel

bridges, subways, concentrations of
metal, car washes, etc.)

• Compass was calibrated incorrectly or

in the presence of a strong magnetic
field.

Perform Calibration. Refer to

MWI-23,

"Description"

.

Compass shows the wrong direction.

Compass does not change direction ap-
pears "Locked".

Compass does not show all the directions,
one or more is missing.

The compass was calibrated but it "loses"
calibration.

On long trips the compass shows the
wrong direction.

Perform Zone Variation Setting if correct
reading is desired in that location. Refer to

MWI-23, "Description"

.

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000007347511

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 SR 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 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 SR 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 har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000007347512

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″

LOCK

″

position.

• Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing work. If

DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-

anism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and

steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, follow the procedure below before

starting the repair operation.

OPERATION PROCEDURE

1. Connect both battery cables.

NOTE:

Supply power using jumper cables if battery is discharged.

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the

″

ACC

″

position. At this time, the

steering lock will be released.

3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be

rotated.

4. Perform the necessary repair operation.

Precaution for Work

INFOID:0000000007830153

• 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 component

with a shop cloth or vinyl tape to protect it.

• Protect the removed parts with a shop cloth and prevent them from being dropped.

• Replace a deformed or damaged clip.

• If a part is specified as a non-reusable part, always replace it with a new one.

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

• After installation is complete, be sure to check that each part works properly.

• Follow the steps below to clean components:

- Water soluble dirt:

• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.

• Then rub with a soft, dry cloth.

- Oily dirt:

• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty

area.

• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.

• Then rub with a soft, dry cloth.

- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.

- For genuine leather seats, use a genuine leather seat cleaner.
