NORMAL OPERATING CONDITION

COMPASS

COMPASS : Description

INFOID:0000000005524681

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

INFORMATION DISPLAY

INFORMATION DISPLAY : Description

INFOID:0000000005524682

AMBIENT AIR TEMPERATURE

The displayed ambient air temperature on the information display may differ from the actual temperature
because it is a corrected value calculated from the ambient sensor signal by the unified meter and A/C amp.
Refer to  

MWI-33, "INFORMATION DISPLAY : System Description"

 for details on the correction process.

POSSIBLE DRIVING DISTANCE

The calculated possible driving distance may differ from the actual distance to empty if the refueling amount is
approximately 15   (4 US gal, 3-3/10 Imp gal) or less. This is because the refuel control (moves the fuel
gauge needle quicker than normal judging that the driver is refueling the vehicle) is not performed in such a
case.

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, carwashes, etc.)

• Compass was calibrated incorrectly or in 

the presence of a strong magnetic field.

Perform calibration. Refer to 

MWI-39, "De-

scription"

.

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-39, "Description"

.

PRECAUTIONS

PRECAUTION

PRECAUTIONS

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

INFOID:0000000005524683

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 AIR BAG” and “SEAT BELT” 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 AIR BAG”.

• 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 Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition 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.
