Title:
INITIAL CALIBRATION OF COMPASS
DURING PDS

Models:
'07 GS 350 & GS 430

August 8, 2006

Introduction





The compass indicates the direction that the vehicle is heading by detecting the direction and strength of the Earth's magnetic field and processing this data using the compass sensor and microcomputer.

Detection of the direction and strength of the Earth's magnetic field varies according to the area in which the vehicle is used and is affected by the residual magnetism of the vehicle. For this reason, the geographic direction displayed may also deviate from the direction determined by the Earth's magnetic field according to the area in which the vehicle is used.

Please perform the initial calibration of the compass prior to vehicle delivery to customers.

Applicable Vehicles

^ 2007 model year GS 350 and GS 430 vehicles.

Compass Calibration Procedure





1. Turn the ignition switch to the "ON" position and check that the direction (N, NE, E, SE, S, SW, W, NW) appears on the compass display.

NOTE:
Pushing the "AUTO" switch turns ON or OFF the compass display.





2. Push the AUTO" switch for approximately 6 seconds until the zone number (1 - 15) appears on the display. Then push the switch to select the number of the zone where the vehicle is located.





See the map for zone reference.

3. Check that the direction appears several seconds after adjustment.





4. Start the engine and push the switch for about 12 seconds until "CAL" appears on the display.





5. Drive the vehicle slowly at 5 mph (8 km/h), or less, in a circle until the direction is displayed. If there is not enough space to drive in a circle, drive around the block until the direction is displayed.

After driving in 1 to 3 circles in the above method, calibration is complete with the direction shown on the display.

NOTE:

^ Do NOT perform calibration of the compass in a place where the Earth's magnetic field is subject to interference by artificial magnetic fields (underground parking, under a steel tower, between buildings, roof parking, near a railroad crossing, near a large vehicle, etc.)

^ During calibration, do NOT operate electric systems (moon roof, power windows, etc.) as they may interfere with the calibration.
