Calibration

CALIBRATION

1. CALIBRATE COMPASS

NOTE: Do not place magnetic or metal objects near the magnetic field sensor.

HINT: These procedures described are for vehicles without the LEXUS navigation system.

a. The location of magnetic north and true north differs depending on the location. Adjustment of the compass' magnetism is required to correct possible compass deviations from true north.
b. Compass function calibration is necessary when: 1)purchasing a vehicle, 2) disconnecting and reconnecting the cable from the negative (-) battery terminal, 3)replacing a battery, 4) driving the vehicle out of the numbered set zone (see the zone map), and 5) placing magnetic or metal objects on or near the accessory meter (multi display).

HINT: If the accessory meter (multi display) is magnetized, the direction indication on the display blinks.

2. PERFORM CALIBRATION

CAUTION:
- Strictly observe posted speed limits, traffic laws and road conditions.
- Make sure no people are near the vehicle.

NOTE:
- Perform the circling calibration in a spacious area that does not have artificial magnetic influence. For example, an underground parking lot, an area under a steel tower and an area between tall buildings are not acceptable.
- When performing calibration, do not operate the air conditioner, power window, or any other electrical equipment.
- A compass may become magnetized when the vehicle is shipped by vessels or freight cars. Make sure to perform calibration properly. If calibration cannot be completed despite performing the circling calibration described, the vehicle's magnetic field may be interfering with the calibration. Demagnetize the vehicle using a demagnetizer and perform calibration again.

a. Circling calibration

1. Select compass mode.
2. Press ODO/TRIP and RESET simultaneously and hold them for 3 seconds to enter the compass correction mode.
3. Press ODO/TRIP.
4. Drive the vehicle slowly in a circle once within 128 seconds.

HINT:
- After the circling calibration is completed, the correct direction is displayed automatically.
- If ODO/TRIP is pressed in step (4), compass correction mode is canceled.
- If the correct direction is not displayed after driving the vehicle as specified, change the vehicle location.

5. If not enough space is available to drive in a circle, perform the following:
- Drive the vehicle forward with the steering wheel fully turned to the right, and then drive in reverse with a steering wheel fully turned to the left.
- Repeat the pattern above 2 times within 128 seconds.

HINT:
- After the circling calibration is completed, the correct direction is displayed automatically.
- If ODO/TRIP is pressed in step (5), compass correction mode is canceled.
- If the correct direction is not displayed after driving the vehicle as specified, change the vehicle location.




b. Zone setting
1. Select compass mode.
2. Press ODO/TRIP and RESET simultaneously and hold them for 3 seconds to enter the compass correction mode.
3. Press RESET to select a higher zone number.
4. Press ODO/TRIP to end the compass correction mode.
