Average vehicle speed mode
Average vehicle speed is calculated and displayed based
on total driving distance and total driving time with the
engine running.
The displayed value is updated every 10 seconds.
To reset the calculations, push and hold the “RESET” button for
more than 1 second. 
Barometer modeIn barometer mode, the atmospheric pressure in the
vehicle is displayed.
The displayed atmospheric pressure ranges from 17.8 IN.HG
(600 hPa) up to 31.0 IN.HG (1050 hPa).
The displayed value is updated every 2 seconds.
The displayed value may deviate from the actual atmospheric
pressure depending on opening or closing of the windows and
doors and the driving conditions.

Altimeter mode
In altimeter mode, the approximate altitude is displayed.
The displayed altitude ranges from −1500 ft. (−500 m) up to
13000 ft. (4000 m).
As the altitude value is converted from the atmospheric
pressure, it can be easily affected by air motion and
temperature, so the indication may vary. The indicated altitude
of a single position may deviate according to the atmospheric
pressure and temperature.
The displayed value is updated every 2 seconds.
RECTIFICATION OF THE ALTITUDE
Rectification is valid only when the correct altitude is known.
While the altitude mode is on the display, push the “
” or “”
button to increase or decrease the altitude by 50 ft. (10 m).
To reset the rectified altitude, push and hold the “RESET”
button for more than 1 second. 
Elapsed time mode
The time that has elapsed since the engine started is
displayed.
When the engine is started, driving time is counted from 0:00.
Up to 19:59 (19 hours, 59 minutes) can be displayed. When
the driving time exceeds 19:59, the counter returns to 0:00.
To reset the calculations, push and hold the “RESET” button for
more than 1 second.

Compass
The compass indicates the direction in which the vehicle
is heading. The illustration shown above indicates the
vehicle is heading north.
Push the “COMP” switch to turn the compass system on
and off.
If the ignition switch was turned off with the system on, the
system will automatically turn back on when the ignition switch
is turned on. Displays

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 on or near the inside rear view mirror.)
 The battery has been disconnected.
Your vehicle is out of the set zone. Refer to the “Calibrating the
compass” in this section to set the zone number.
The compass works to calibrate the direction automatically
while the vehicle is in motion, if deviation is small.

“Calibrating the compass” below.
If the direction is not indicated or the system does not operate
properly, contact your Lexus dealer.

Compass sensor
NOTICE
Do not put magnets or a metal object on or near the
inside rear view mirror of the vehicle. Doing this may
cause malfunction of the compass sensor in the mirror.
Calibrating the compass (deviation calibration)
The direction display on the compass deviates from the true
direction determined by the earth’s magnetic field. The angle
of deviation varies according to the geographic position of the
vehicle.
To adjust this deviation, stop the vehicle, then push and hold
the “COMP” switch until the zone number appears on the
display. Then push the “COMP” switch, referring to the
following map to select the number of the zone where the
vehicle is.

 Zone numbers
Leaving the system after the calibration for several seconds,
the direction will appear on the display. It shows the zone
number is set.
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)
To rectify the compass, stop the vehicle and push and hold the
“COMP” switch until “C” appears on the display.
There is also a case that “C” appears on the display in case of
the drastic change of the magnetic field.

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. 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.
 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.

the set temperature.
In the automatic operation mode, the air conditioning selects
the most suitable fan speed, air flow, air intake and on−

air conditioning according to the temperature.
The ignition key must be in the “ON” position.
NOTICE
To prevent the battery from being discharged, do not
leave the air conditioning on longer than necessary
when the engine is not running.
