ItemDetails
Computer areaDisplays cruise information. In addition, the contents of the display can be switched by
operating the DISP1 of the steering pad switch.
Graphic area
Displays the following information (radar cruise, clearance sonar, open door, compass,
and outside temperature). The items from "Compass" to "Blank" (via outside
temperature) can be switched by operating the DISP2 of the steering pad switch.
Warning areaDisplays warning messages. These messages appear only if an abnormal signal has been
input by a system.
Master
warning
indicatorComes on/blinks with buzzer sounding in accordance to direction from the displayed
item in the warning area.

Warning process:
The warning items can be scrolled automatically. (Unable to switch manually)
When any malfunction in the framed items is detected, a warning buzzer (a single sound)
sounds. It sounds only when the malfunction occurs for the first time. The item is displayed
along with the buzzer sounding.
The most current warning item is displayed first.
When two or more warning occur, they are displayed in turn at an interval of 2 seconds.
When a warnings occurs, the item is displayed for 6 seconds only the first time.
Smart Key System:
The buzzer in the smart key system is controlled by a signal from the security ECU.
HINT:
The buzzer sounds continuously if the item "Shift to P range" is displayed.
Oil Maintenance Display:
The items are displayed in accordance with the distance after reset (see ON-VEHICLE

INSPECTION ).
b. Computer area
The items from "Range Over ***/Range Approx ***" to "BLANK" can be changed with the
DISP1 (switch) of the steering pad switch.
c. Graphic area

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.

5.SETTING COMPASS

6.SELECTING DISPLAY MODE
a. Turn the ignition switch to the ON position.
b. Check that the compass display indicates an azimuthal direction (N, NE, E, SE, S, SW, W, or NW).
7.ZONE SETTING MODE
Usin
g the hand-held tester, select the customize menu.

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.
