Calibrating the compass
The 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 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.
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.

■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 12 volt battery has been disconnected.
●A door is open.

CAUTION
■While driving
Do not adjust the display.
Be sure to adjust the display only 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 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, frequent
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 the vehicle consumes more than this amount, contact your Lexus dealer.
■Resetting the engine oil maintenance data (U.S.A. only)
Perform the following steps:
Press the “DISP” switch (P. 169) to change the multi-information dis-
play to blank.
Turn the “POWER” switch to OFF.
Turn the “POWER” switch to ON mode with the trip meter reset button
held down.
Keep pressing the button for longer than 7 seconds after the “POWER”
switch is in ON mode.

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
■When refilling the washer fluid
Do not refill the washer fluid when the hybrid system is hot or operating, as the
washer fluid contains alcohol and may catch the fire if spilled on the hybrid system
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 safe place and turn the “POWER” switch to
OFF.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (P. 5 9 6 )
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.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly three times and the mes-
sage “PRESSURE INITIAL”
appears on the multi-information
display.
Wait for a few minutes with the ON mode, and then turn the
“POWER” switch to OFF.

■Initializing the tire pressure warning system
Initialize the tires with the tire inflation pressure adjusted to the specified level.
■If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified level
and initialize the 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
blinks for 1 minute then stays on after driving for 20 minutes.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
