Title:
INITIAL CALIBRATION OF COMPASS
DURING PDS

Models:
'07 IS 250 & IS 350

August 1, 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.





Perform the initial calibration of the compass in your dealership prior to delivery to the customer.

Applicable Vehicles

^ 2007 model year IS 250 and IS 350 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 the compass display ON or OFF.

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

4. 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 calibration is complete and the direction will show 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 (sliding roof, power windows, etc.) as they may interfere with the calibration.
