Dynamic radar cruise control—
If the system cannot easily measure the
vehicletovehicle distance because of a dirty millimeter
wave radar sensor or grille cover while the dynamic radar
cruise control is on, the master warning light comes on
and the “CRUISE” indicator light flashes. At this time a
warning tone sounds and the above message appears.
If this message appears, clean the sensor and grille cover with
a soft cloth and try setting the preset speed again. If the dirt
is removed without cleaning, the system will automatically
enter the “RADAR READY” mode. If the system does not enter
the “RADAR READY” mode even after cleaning or the
message remains on the display, the system might be
malfunctioning. Although it is no problem to continue driving,
contact your Lexus dealer. Dynamic laser cruise control—
If the system cannot easily measure the
vehicletovehicle
distance because of a dirty laser radar
sensor glass while the dynamic laser cruise control is on,
the master warning light comes on and the “CRUISE”
indicator light flashes. At this time a warning tone sounds
and the above message appears.
If this message appears, clean the sensor glass with a soft
cloth and try setting the preset speed again. If the dirt is
removed without cleaning, the system will automatically enter
the “RADAR READY” mode. If the system does not enter the
“RADAR READY” mode even after cleaning or the message
remains on the display, the system might be malfunctioning.
Although it is no problem to continue driving, contact your
Lexus dealer.

The compass may not show the correct direction in the
following conditions:
 The vehicle is stopped immediately after turning.
The compass does not adjust while the vehicle is stopped.
 The ignition switch is turned off immediately after turning.
 The vehicle is on an inclined surface.
 The vehicle is 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.). 
The vehicle is magnetized. (There is a magnet or a metal
object near the audio system.)
 The battery has been disconnected.
If the deviation is small, the compass works to calibrate the
direction automatically while the vehicle is in motion.
For obtaining additional precision or for complete calibrating,
see “CALIBRATING THE COMPASS” on page 107.
COMPASS SENSOR

 Compass sensor
The compass sensor is located behind the audio system.

GAUGES, METERS AND SERVICE REMINDER INDICATORS

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.
