STEERING WHEEL AND MIRRORS
214When the outside air temperature is low, it may take a little
longer for the mirror to darken in response to the detection of
headlights.
CAUTION
Do not adjust the mirror while the vehicle is moving.
Doing so may cause the
driver to mishandle the vehicle
and an accident may occur resulting in death or serious
injuries.
G17008
To ensure correct functioning of antiglare mirror sensors
located on both sides of the mirror, do not touch or cover
the sensors with your finger or a piece of cloth, etc.
Compass

The compass indicates the direction in which the vehicle
is heading. The illustration shown above indicates the
vehicle is heading north.

Pushing the “AUTO” button for longer than 3 seconds
turns on or off the compass display.
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 engine 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 inside rear view mirror.)
 The battery has been disconnected.
 Any door is open.
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” below.
NOTICE
Do not put magnets or a metal object near the inside rear
view mirror. Doing this may cause malfunction of the
compass sensor.
CALIBRATING THE COMPASS (deviation calibration)
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.
To adjust for this deviation, stop the vehicle and push the
“AUTO” button for longer than about 6 seconds until the zone
number (1 −15) appears on the display. Then push the button
again, referring to the following map to select the number of the
zone where the vehicle is.

Zone number
If the direction is displayed several seconds after adjustment,
the calibration is finished.
CAUTION
Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.
CALIBRATING THE COMPASS (circling calibration)
G17011
“CAL” appears on the display in case the circling calibration is
required due to a drastic change in the magnetic field. To
rectify this, follow the calibration procedure below.

STEERING WHEEL AND MIRRORS
217
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.
 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.

on.
NOTICE
To prevent the battery from being discharged, do not
leave the cover open for a long time while the engine is
stopped.

TOUCH SCREEN
224Average Speed
The Average Speed is displayed. The average vehicle
speed is calculated and displayed based on the total
driving
distance and the total driving time after the engine
is started.
The displayed value is updated every 10 seconds.
To calculate from the beginning, touch the “Reset” switch.
Distance
The distance after engine starting is displayed.
When refueling, be sure to stop your vehicle and turn the
engine switch off.
