Calibrating the compassThe 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”.

Deviation calibration
Stop the vehicle in a place where it is safe to drive in a circle.
Press and hold the switch.
A number (1 to 15) appears on the
compass display.
Referring to the map above, press the switch to select the number
of the zone you are in.
If the direction is displayed several seconds after adjustment, the cali-
bration 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 a direction is displayed.

■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 park/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 battery has been disconnected.
●A door is open.
CAUTION
■While driving the vehicle
Do not adjust the display. Adjust the display only when the vehicle is stopped.
■When 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
■To avoid compass malfunctions
Do not place magnets or any metal objects near the inside rear view mirror.
Doing this may cause the compass sensor to malfunction.
■To ensure normal operation of the compass
●Do 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.
●During calibration, do not operate electric systems (moon roof, power windows,
etc.) as they may interfere with the calibration.

■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 conditions such as high speeds and fre-
quent acceleration and deceleration.
●A new engine consumes more oil.
●When 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.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 Imp. qt./600 miles (1.0 L per 1000
km)
●If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Lexus dealer.
■After changing the engine oil (U.S.A. only)
The engine oil maintenance data should be reset. Perform the following proce-
dures:Switch the display to the trip meter “A” when the hybrid system is operat-
ing. (→P. 1 6 3 )
Turn the “POWER” switch off.
While pressing the trip meter reset button ( →P. 1 6 3 ) , t u r n t h e “ P O W E R ”
switch to ON mode (do not start the hybrid system because otherwise
the reset mode will be canceled). Continue to press and hold the button
until the trip meter displays “000000” and the multi-information display
indicates that the reset is complete.

Washer fluidIf any washer does not work or the
warning message appears on the
multi-information display, the
washer tank may be empty. Add
washer fluid.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear out or
when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious problem.
CAUTION
■When adding washer fluid
Do not add washer fluid when the hybrid system is hot or operating as washer fluid
contains alcohol and may catch fire if spilled on the engine etc.
NOTICE
■Do 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.
■Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the washer fluid tank.

How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the “POWER” switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( →P. 5 5 7 )
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the “POWER” switch to ON mode.
Press and hold the tire pressure warning reset switch until the tire
pressure warning light flashes slowly 3 times and the message
“TIRE PRESSURE RESET PROCEEDING” appears on the

and initialize the tire pressure warning system again.
■When the initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following cases,
the settings have not been recorded and the system will not operate properly. If
repeated attempts to record tire inflation pressure settings are unsuccessful, have
the vehicle inspected by your Lexus dealer.
●When operating the tire pressure warning reset switch, the tire pressure warn-
ing light does not flash 3 times and the setting message does not appear on the
multi-information display.
●After carrying out the initialization procedure, the tire pressure warning light
