1. MULTI INFORMATION DISPLAY ILLUMINATION
Turn the ignition switch to the ON position and illuminate the all
parts of the display by pushing the ºLIGHTº button.
2. PERFORM CIRCLING CALIBRATION
(a) Push the ºMODEº button several times until ºCOM-
PASSºappears and blinks on the calendar display.
(b) Then push the ºRESET/ADJº button. ºCALIBRATEº ap-
pears and blinks together with the compass display.
(c) Drive the vehicle in a circle until the blinking stops.
(d) If there is not enough space to drive in a circle, drive
around the block until the blinking stops.
(e) When the compass and the calendar display return to
normal mode, calibration is complete

NOTICE:

Do not perform circling calibration of the compass in
a place where the earth's magnetic field is subject to
interference by artificial magnetic fields (under-
ground parking, under a steel tower, between build-
ings, roof parking, near a crossing, near a large ve-
hicle, etc.).

During calibration, do not operate electric systems
(moonroof, power windows, etc.) as they may inter-
fere with the calibration.

If you want to cancel the calibration before it is com-
plete, push the ºMODEº button again.
HINT:
A compass could be magnetized during by vessels of freight
cars. Before delivery, therefore, make sure to perform calibra-
tion and ensure that calibration can be done. If cannot be done
(cannot complete in spite of driving round several times), it may
be caused by magnetization. Demagnetize the vehicle using a
demagnetizer and preform calibration again.
3. PERFORM DEVIATION CALIBRATION
(a) Stop the vehicle and push the ºMODEº button several
times until ºZONE XXº appears on the calender display.
(b) Then push the ºRESET/ADJº button, referring to the fol-
lowing map to select the number of the zone where the
vehicle is.
(c) After calibration, push the ºMODEº button several times
until the calendar display returns to the normal mode.

INSPECTION
1. A/C control panel assembly:
INSPECT DEFOGGER SWITCH OPERATION
(a) Connect the positive (+) lead from the battery to terminal
17, 18 and negative (-) lead to terminal 40.
(b) Connect the positive (+) lead from the battery to terminal
24 through a 1.4 W test bulb.
(c) Turn the defogger switch ON and check that the test bulb
and indicator light turn ON, then turn OFF after about 15
minutes.
If operation is not as specified, proceed to the next inspection.
2. INSPECT DEFOGGER RELAY CONTINUITY
ConditionTester connectionSpecified condition
Constant3 - 4Continuity
Apply B+ between
terminals 3 and 4.1 - 2Continuity
If continuity is not as specified, replace the relay.
3. W/ Mirror defogger:
INSPECT MIRROR DEFOGGER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
3 and the negative (-) lead to terminal 6.
(b) Check that the mirror becomes warm.
HINT:
It will take a short time for the mirror to become warm.
If the mirror does not become warm, replace the mirror assem-
bly.
4. W/ Mirror defogger and driving position memory:
INSPECT MIRROR DEFOGGER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
5 and the negative (-) lead to terminal 10.
(b) Check that the mirror becomes warm.
HINT:
It will take a short time for the mirror to become warm.
If the mirror does not become warm, replace the mirror assem-
bly.

5. INSPECT DEFOGGER WIRE
NOTICE:
When cleaning the glass, use a soft, dry cloth, and wipe the
glass in the direction of the wire. Take care not to damage
the wires. Do not use detergents or glass cleaners with
abrasive ingredients. When measuring voltage, wind a
piece of tin foil around the top of the negative probe and
press the foil against the wire with your finger, as shown.
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
(c) Inspect the voltage at the center of each heat wire, as
shown.
VoltageCriteria
Approx. 5 VOkay (No break in wire)
Approx. 10 V or 0 VBroken wire
HINT:
If there is approximately 10 V, the wire is broken between the
center of the wire and the positive (+) end. If there is no voltage,
the wire is broken between the center of the wire and ground.
(d) Place the voltmeter positive (+) lead against the defogger
positive (+) terminal.
(e) Place the voltmeter negative (-) lead with the foil strip
against the heat wire at the positive (+) terminal end and
slide it toward the negative (-) terminal end.
(f) The point where the voltmeter deflects from zero to sever-
al V is the place where the heat wire is broken.
HINT:
If the heat wire is not broken, the voltmeter indicates 0 V at the
positive (+) end of the heat wire but gradually increases to about
12 V as the meter probe is moved to the other end.
6. IF NECESSARY, REPAIR DEFOGGER WIRE
(a) Clean the broken wire tips with a grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire to be
repaired.
(c) Thoroughly mix the repair agent (Dupont paste No.
4817).

(d) Using a fine tip brush, apply a small amount to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours.
