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 th e map above, select the number
of the zone where you are.

Press AUTO again.
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 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 battery has been disconnected.
●A door is open.

CAUTION
■While driving the vehicle
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.

Maintenance and care
■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 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 you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles (1000 km),
contact your Lexus dealer.
■After changing the engine oil (U.S.A. only)
The oil change system should be reset. Perform the following procedures:
Switch the display to the odometer ( P. 105) when the engine is running.
Turn the engine switch OFF.
While pressing the trip meter reset bu tton, set the engine switch to the
IG-ON mode (but do not start the engine because otherwise the reset
mode will be cancelled) . Continue to press and hold the button until the
trip meter displays 000000.
CAUTION
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammati on or skin cancer, so care should be taken to avoid
prolonged and repeated contact. To remove used engine oil from your skin, wash
thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do not dis-
pose of used oil and filters in househol d trash, in sewers or onto the ground.
Call your Lexus dealer, service station or auto parts store for information con-
cerning recycling or disposal.
●Do not leave used engine oil within the reach of children.

Never recharge the battery while the engine is running. Also, be sure all accesso-
ries are turned off.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.

■Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the washer fluid tank.

The tire pressure initialization
setting display
Continue to press the  or 
switch until the initialization setting
display appears.
It may take several minutes to com-
plete the setting. Wait for several
minutes before turning the engine
switch OFF if necessary.
Recording tire pressure settings
Press the ON/OFF button for
more than 3 seconds. At this time,
the tire inflation pressure warning
indicator flashes 3 times and the
message showing that the initial
setting is complete is displayed on
the multi-information display.
Registering and selecting tire inflation pressure sensor ID codesThe tire inflation pressure sensor is equipped with a unique ID code.
To select tire inflation pressure sensor ID codes, use the satellite switch.
( P. 218)
■ Registering ID codes
Two separate sets of ID codes can be registered for each vehicle. This
allows 2 separate sets of settings to be conveniently recorded for all
season and winter tires.
MAIN: The MAIN ID code is used fo r the factory installed tire pres-
sure sensors.
2nd: The 2nd ID code is used for tire inflation pressure sensors associ-
ated with a secondary set of tires.
Make sure to have all tire inflation pressure warning system ID codes regis-
tered by your Lexus dealer. ID codes must be reset when tires or wheels are
replaced.

Maintenance and care
■Selecting ID codes
When replacing tires, make sure to select the ID code set that matches
the new tire set. If the incorrect ID code is selected, the tire pressure
warning system will not operate properly.
Tire pressure ID code settings
display
Press  or  repeatedly until the
setting display appears.
Switching ID codes
Press the ON/OFF button to
switch between MAIN and 2nd ID
codes.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to expose the
fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with your Lexus dealer.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Low profile tires (vehicles not equipped with 205/55R16 tires)
Generally, low profile tires will wear more rapidly and tire grip performance will be
reduced on snowy and/or icy roads when co mpared to standard tires. Be sure to
use snow tires or tire chains
* on snowy and/or icy roads and drive carefully at a
speed appropriate for road and weather conditions.
*: Tire chains cannot be mounted on 18-inch tires.
