Preliminary CheckNIS001OR
Remove the fuse No.18 for the back door closure with the back door closure inactive.
Check that the back door can be open / close normally.
CAUTION:
It is judged it is abnormal, discontinues closure operation, and drive lever returns to a neutral position
if not becoming full-latch within about three seconds after half-latch.
When this operation is done continuously three times, both back door closure and back door opener
switch are not operated because the function of back door closure is stopped.
Thing to reset power supply by pulling out and opening fuse in that case.

FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.

Unified meter and A/C amp. reads a resistor signal from fuel level sensor.
Signal is supplied
–from unified meter and A/C amp. terminal 36
–through the fuel level sensor unit and fuel pump (main) terminals 5 and 2, and
–through the fuel level sensor unit (sub) terminals 2 and 1
–to unified meter and A/C amp. terminal 28 for the fuel gauge.

Unified meter and A/C amp. provides a fuel level signal to combination meter with communication line.

Combination meter indicates the approximate fuel level according to the fuel level signal.
ODO/TRIP METER

ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C
amp. with CAN communication.

Unified meter and A/C amp. converts the vehicle speed signal to the 8-pulse signal, and outputs the vehi-
cle speed signal (8-pulse) to combination meter.

Combination meter uses the vehicle speed signal (8-pulse) to calculate the mileage, and displays it.
How to Change The Display For Odo/trip Meter
Switch modes with following procedure.

When trip transfer switch is pressed, trip meter display changes.

If trip reset switch is pressed for 1 second or more while “trip A”
is displayed, only “trip A” is reset.
NOTE:
The record of the odo meter is kept even if the battery cable is dis-
connected. The record of the trip meter is erased when the battery
cable is disconnected.

COMPASS
Revision: 2006 July 2007 FX35/FX45
COMPASSPFP:24835
Precautions for CompassNKS003HQ
NOTE:

Do not install the ski rack, antenna, etc. which is attach to the vehicle with a magnet base. It affects the
operation of the compass.

When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not
spray glass cleaner directly on the mirror as it may cause the liquid cleaner to enter the mirror housing.
System DescriptionNKS003HR

This electronic compass is able to display 8 primary directions:
N, NE, E, SE, S, SW, W, NW.

The inside mirror switch (2) is used to operate the compass and
automatic anti-glare system.
Switch Operation
NOTE:
For further details of the compass and automatic anti-glare system, refer to Owner's Manual

All standard compasses determine direction relative to Magnetic North; however, this electronic compass
is designed to display direction relative to True North.

The difference between Magnetic North and True North varies from place to place across the surface of
the earth.

This electronic compass must be “told” approximately where it is on the earth’s surface so that the Mag-
netic North reading can be properly converted into a True North display.

To tell the electronic compass where it’s at, the earth is separated into numbered “Zone Variances”. The
Zone Variance number in which the compass is to function must be entered into this electronic compass.

Each zone is magnetically about 4.2 ° wide. Typically, anything under 22.5 ° total zone change is not
noticed on the electronic compass display. However, over 22.5 °, a reading may be off by one or more pri-
mary directions.

On long trips, a vehicle may leave its original zone and enter one or more new zones. Generally, you do
not need to reset the compass zone if you travel between 3 or 4 zones, such as business travel or vaca-
tion. The typical driver will not notice any difference on the display within 3 or 4 zones. However, if the
vehicle is “permanently” moved to a new location, it is recommended that the compass zone be reset.

Zone Variation Setting ProcedureNKS003HT
NOTE:
The zone setting is factory preset (“default” setting) to zone 8.
1. Press and hold the inside mirror switch for 6 – 9 seconds.
2. The current zone setting appears on the compass display.
3. Find the current geographical location number in the Zone Varia- tion Chart.
4. Select the new zone number. (Press the inside mirror switch until the new zone number appears on the compass display.)
5. After select the new zone number, the compass display will automatically shows a direction within a few seconds.
6. Preform the following Calibration Procedure for more accurate indications.
Calibration ProcedureNKS003HU
NOTE:
The compass calibrates itself under normal driving conditions. However, occasional circumstances may cause
the compass to operate inaccurately. Example: Driving from rural (wide open) areas to crowded city areas, or
if an aftermarket (i.e., non original equipment) antenna with a magnetic base is attached to the vehicle. Cali-
brate the mirror compass if the display shows only one direction or a limited number of directions.
NOTE:

If “magnetic hats” are used in the dealership for vehicle identification, remove the hat from the vehicle
before performing the following steps. Do NOT put the hat back on the vehicle after the procedure is com-
pleted.

Drive the vehicle to an open level area; away from large metallic objects, structures, and overhead power
lines.

Turn off “non-essential” electrical accessories (rear window defrost, heater/air conditioning, wipers) and
close the doors.
1. Verify the correct compass zone setting for the geographical location. Refer to DI-108, "
Zone Variation
Setting Procedure" .
2. Press and hold the inside mirror switch for more than 9 seconds.
3. “C” is displayed on the compass display, when calibration starts.
4. Drive slowly [less than 8 km/h (5 mph)] in a circle until the “C / CAL” is replaced with primary headings (N, NE, E, SE, S, SW, W, or NW).
NOTE:
This will require driving at least 2 complete 360 degree circles; 3 complete circles may be required.
5. The compass calibration procedure is now complete. The compass should operate normally.
NOTE:
If at any time the compass continually displays the incorrect direction or the reading is erratic or locked,
repeat the calibration procedure.
