Calibrating the compassThe direction display 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 a map boundary shown in illustration, the compass will devi-
ate. 
To obtain higher precision or perfect calibration, refer to the following.
■ Deviation calibration
Stop the vehicle where it is safe to drive in a circle.
Press “AUTO” until a number (1 to
15) appears on the compass dis-
play.
Press “AUTO”, and referring to the map above, select the number
of the zone where you are.

Wait a few seconds until the compass direction is displayed.
The calibration is complete.
■Circling calibration
If “CAL” appears on the display,
drive the vehicle at 5 mph (8 km/
h) or less in a circle until a direction
is displayed.
If there is not enough space to
drive in a circle, drive around the
block until the direction is dis-
played.
STEP4
■Conditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
●The vehicle is stopped 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 interfer-
ence by artificial magnetic fields (underground car park/parking lot, under a
steel tower, between buildings, roof car pa rk/parking lot, near an intersection,
near a large vehicle, etc.).
●The vehicle has become magnetized. 
(There is a magnet or metal object near the inside rear view mirror.)
●The 12 volt battery has been disconnected.
●A door is open.

CAUTION
■Caution while driving
Do not adjust the display.
Be sure to adjust the display on ly when the vehicle is stopped.
■When doing the circling calibration
Be sure to secure a wide space, and watch out for people and vehicles in the neigh-
borhood. Do not violate any local traffic rules while performing circling calibration.
NOTICE
■To avoid the compass malfunctions
Do not place magnets or any metal objects near the inside rear view mirror. 
Doing this may cause a malfunction of the compass sensor.
■To ensure normal operation of the compass
●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.
●During calibration, do not operate electr ic systems (moon roof, power windows,
etc.) as they may interfere with the calibration.

4-3. Do-it-yourself maintenance
■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
●More oil is consumed under driving co nditions such as high speeds and fre-
quent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumpt ion, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per 1000
km). If the vehicle consumes more than this amount, contact your Lexus dealer.
■Resetting the engine oil main tenance data (U.S.A. only)
