NOTICE
Do not put magnets or a metal object near the audio
system. Doing this may cause malfunction of the
compass sensor.
CALIBRATING THE COMPASS
The direction display on the compass deviates from the true
direction determined by the earth’s magnetic field. The
amount of deviation varies according to the geographic
position of the vehicle.
If you cross over the area divided as shown in the illustration,
the compass will deviate. If it is necessary to calibrate the
compass (deviation calibration), take your vehicle to your
Lexus dealer. Even if you do not cross over, the compass may
sometimes deviate. If this happens, perform “DRIVE IN
CIRCLES” calibration as shown on the next page.

To rectify the deviation, stop the vehicle, and push and hold the
“RESET” button on the steering pad for more than 6 seconds.
“DRIVE IN CIRCLES” appears on the display. Perform the
following calibration.
CAUTION
Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.
13L155
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 direction shown on the display.
If calibration cannot be performed because the vehicle is
magnetized, take your vehicle to a Lexus dealer.
If you want to cancel the calibration before it is complete, push
and hold the “RESET” button on the steering pad more than 6
seconds. To calibrate the compass again, push and hold the
same but ton more than 6 seconds. After “DRIVE IN CIRCLES”
appears on the display, follow the calibration procedure above.
Perform circling calibration just after you have purchased
your Lexus. And then always perform circling calibration
after the battery has been removed, replaced or
disconnected.

GAUGES, METERS AND SERVICE REMINDER INDICATORS

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.).
 During calibration, do not operate electric systems (moon
roof, power windows, etc.) as they may interfere with the
calibration.
CAUTION
When doing the circling calibration, be sure to secure
a wide space, and watch out for people and vehicles
in the neighborhood. Do not violate any local traffic
rules while performing circling calibration.
 Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.

224When the registration is completed, one beep sounds. If the
key has already been registered, the previous memory will be
erased. If the same driving position profile for the same key is
registered
in another button, that memory will also be erased.
CAUTION
Do not push the “LOCK” button any longer than 2 or 3
seconds. Pushing the button longer activates an alarm.
For details, see page 40.
Erasing the previous registration memory
The driver’s door must be closed with the ignition switch in the

to cancel the registrati on in possession and push the
“SET” button.
2. Push the “LOCK” or “UNLOCK” button on the wireless
remote control key for about one second with the “SET”
button held down.
When the previous key ID memory is erased, two beeps
sound.
REAR SEAT POSITION MEMORY SYSTEM
A microcomputer will memorize the position of the rear seats
and the height of the rear head restraints.
Recording the rear seat position in the computer’s memory can
only be done when the ignition switch is in the “ON” position.
Setting the rear seat position

1. Adjust the rear seat position and the height of the head
restraint of the rear seat to the desired position.
2. Keep pushing the “SET” button until a beep sounds.
The beep sound means that the position has been memorized.
The memory will be erased when the battery is removed for
inspection or service.
