Calibrating the compass
The direction display deviates from the true direction determined by the
earth’s magnetic field. The amount of deviation varies depending on the
geographic position of the vehicle.
If you cross over one of the map boundaries shown in illustration, the com-
pass will deviate.
To obtain higher precision or perfect calibration, refer to “Deviation calibra-
tion”.

nDeviation calibration
Stop the vehicle.
Press and hold “AUTO”.
A number (1 to 15) appears on the
compass display.
Referring to the map above, press “AUTO” to select the number
of the zone where you are in.
If the direction is displayed for several seconds after adjustment, the
calibration is complete.
nCircling calibration
If “C” 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 a direction is displayed.

Interior features
nConditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
lThe vehicle is stopped immediately after turning.
lThe vehicle is on an inclined surface.
lThe 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 park/parking lot, near an intersection,
near a large vehicle, etc.).
lThe vehicle has become magnetized. (There is a magnet or metal object near
the inside rear view mirror.)
lThe battery has been disconnected.
lA door is open.
CAUTION
nWhile driving the vehicle
Do not adjust the display. Adjust the display only when the vehicle is stopped.
nWhen doing the circling calibration
Secure a wide space, and watch out for people and vehicles in the vicinity. Do not
violate any local traffic rules while performing circling calibration.
NOTICE
nTo avoid compass malfunctions
Do not place magnets or any metal objects near the inside rear view mirror.
Doing this may cause the compass sensor malfunction.
nTo ensure normal operation of the compass
lDo not perform a circling calibration of the compass in a place where the earth's
magnetic field is subject to interference by artificial magnetic fields.
lDuring calibration, do not operate electric systems (moon roof, power windows,
etc.) as they may interfere with the calibration.

nEngine oil consumption
lThe amount of engine oil consumed depends on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
lMore oil is consumed under driving conditions such as high speeds and fre-
quent acceleration and deceleration.
lA new engine consumes more oil.
lWhen judging the amount of oil consumption, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
lOil consumption: Max. 1.1 qt./600 miles (0.9 Imp. qt./600 miles, 1.0 L/1000
km)
lIf your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Lexus dealer.
nAfter changing the engine oil (U. S. A. only)
The engine oil maintenance data should be reset. Perform the following procedure:
Display the trip meter “A” (→P. 167), then turn the “ENGINE START
STOP” switch off.
While pressing the “ODO/TRIP” button, turn the “ENGINE START
STOP” switch to ON mode.
STEP1
STEP2
Keep the “ODO/TRIP” button pressed for
about 5 seconds. The resetting procedure is
complete when “000000” in the trip meter
flashes once and the message in the multi-
information display disappears.

Maintenance and care
Washer fluid
If any washer does not work or the
warning message appears on the
multi-information display, the
washer tank may be empty. Add
washer fluid.
CAUTION
nWhen adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid contains
alcohol and may catch fire if spilled on the engine etc.
NOTICE
nDo not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces.
nDiluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the washer fluid tank.
