G17012
Drive the vehicle slowly (at 8 km/h (5 mph) or lower) 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 "CAL" off the display and the direction
shown on the display.
If calibration cannot be performed because of the vehicle is
magnetized, take your vehicle to a Lexus dealer.
D Do not perform circling 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
crossing, near a large vehicle, etc.).
D During calibration, do not operate electric systems (moon
roof, power windows, etc.) as they may interfere with the
calibration.

in the neighborhood. Do not violate any local traffic
rules while performing circling calibration.
