HINT:
If the warning item other than the door warning is detected at the same time, the master warning
comes on/blinks in accordance to direction from the displayed item in the warning area.
Park Sonar Display:
See HOW TO PROCEED WITH TROUBLESHOOTING for details on the park sonar display.
The display blinks when the clearance is the closest.
Others:
The items "COMPASS", "OUTSIDE TEMPERATURE" and "BLANK" can be changed with the
DISP2 (switch) of the steering pad switch.
While +B is connected, the mode that was on when the ignition switch was turned off the last time
is displayed.
When the display is changed from radar cruise, it is displayed for only 6 seconds and then returns
to the radar cruise display.
While the radar cruise is on, "RADAR CRUISE READY" is displayed in the warning area if the
park sonar and door open displays are in the graphic area.
Radar Cruise Display:
See HOW TO PROCEED WITH TROUBLESHOOTING for details on the radar cruise
display.
The radar cruise set display is interrupted for only 6 seconds while the park sonar and/or open door
(displays) are on.

1.SELECTING COMPASS DISPLAY MODE
The "DISP2" of the steering pad switch allows you to select a Display or Non-display mode of the
compass.
2.SETTING ZONE
Deviation between the magnetic north and "actual north" differs depending on the terrestrial location,
therefore, an adjustment in magnetism is required. Since the magnetic condition differs according to the
area where the vehicle will be used, it is necessary for each user to set the zone. (Refer to "Compass Zone
Map"). The zone setting can be changed using the hand-held tester.
3.PERFORMING CALIBRATION
Because each vehicle has its own magnetic field, calibration should be performed for each vehicle. This
compass function is used when storing the record of the vehicle's magnetic field.
4.WHEN COMPASS MAGNETIZED:
A compass could be magnetized during shipping by vessels or freight cars. Before delivery, therefore,
make sure to perform calibration and ensure that calibration can be done. If it cannot be done (cannot
complete in spite of driving round several times), it may be caused by magnetization. Demagnetize the
vehicle usin
g a demagnetizer and perform calibration again.

8.CALIBRATION SETTING MODE
a. Keep pressing the "RESET" for 6 sec. after selection of the compass display mode will activate the
calibration setting mode.
b. Drive the vehicle at a slow speed of 8 km/h (5 MPH) or less in the circular direction.
c. Driving round the circle 1 to 3 times will display the azimuthal direction on the display, completing
the calibration.
d. To finish the calibration mode, press the DISP2 switch long when the calibration is finished or
during the calibration.

Setting of the vehicle distance can be changed to 3 distances by operating the distance control
switch (DISP2 button): long (approximately 75 m (246 ft)), middle (approximately 50 m (164 ft)),
and short (approximately 30 m (98 ft)) when vehicle speed is approximately 90 km/h (55 mph).
HINT:
Vehicle distance increases and decreases in accordance with vehicle speed.
Controlling condition is indicated on the combination meter multi-information display.

3.INSPECT STEERING PAD SWITCH ASSY
a. Turn the ignition switch to the ON position.
b. Push on the ON-OFF button of the cruise control main switch.
c. Push on the distance control switch (DISP2) of the steering pad switch.
d. Check that the indication of vehicle-to-vehicle distance, which is shown in the multi-information
displa
y on the combination meter, changes from "LONG", "MIDDLE" to "SHORT" in that order.
