CAUTION
nWhile driving the vehicle
Do not adjust the display. Be sure to adjust the display only when the vehicle is
stopped.
nWhen 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
nTo 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.
nTo ensure normal operation of the compass
lDo not perform 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 lmp.qt./600 miles (1.0 L per 1000
km)
lIf you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles (1000 km),
contact your Lexus dealer.
nAfter 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. 142) when the engine is running.
Turn the “ENGINE START STOP” switch OFF.
While pressing the trip meter reset button, set the “ENGINE START
STOP” switch to the IGNITION 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
nUsed engine oil
lUsed engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammation 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.
lDispose of used oil and filters only in a safe and acceptable manner. Do not dis-
pose of used oil and filters in household trash, in sewers or onto the ground.
Call your Lexus dealer, service station or auto parts store for information con-
cerning recycling or disposal.
lDo not leave used engine oil within the reach of children.

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.
NOTICE
nWhen recharging the battery
Never recharge the battery while the engine is running. Also, be sure all accesso-
ries are turned off.
CAUTION
nWhen refilling the washer fluid
Do not refill the washer fluid when the engine is hot or running, as the 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.

nHow to initialize the tire pressure warning system
To initialize the system, use the satellite switch. (→P. 260)
Park the vehicle in safe place and turn the “ENGINE START
STOP” switch OFF.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (→P. 4 3 9 )
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 “ENGINE START STOP” switch to IGNITION ON
mode.

ization setting display
Continue to press < or > until the
initialization setting display
appears.
It may take several minutes to com-
plete the setting. Wait for several
minutes before turning the
“ENGINE START STOP” switch to
OFF if necessary.

Maintenance and care
Recording tire inflation pressure
settings
Push and hold the “ON/OFF” but-
ton until the tire pressure warning
light blinks slowly three times and
the message “PRESSURE INI-
TIAL” appears on the multi-infor-
mation display.
Wait for a few minutes with the IGNITION ON mode, and then
turn the “ENGINE START STOP” switch OFF.
Registering and selecting ID codes
To select tire pressure warning valve and transmitter ID codes, use the
satellite switch. (→P. 260)
nRegistering ID codes
2 sets of tire pressure warning valve and transmitter ID codes can be
registered. Once a second set of tires is registered at “2ND”, you can
switch between tire set settings simply by pressing the tire pressure
warning select switch.
There are 2 settings:
“MAIN” position: The ID code of the tire pressure warning valve and
transmitter on the tires originally installed on the vehicle is registered.
“2ND” position:The ID code is not registered. When you replace a
new set of tires, purchase tire pressure warning valves and transmitters
from your Lexus dealer and have the new ID code registered by your
Lexus dealer.

nSelecting ID codes
When replacing tires, make sure to select the ID code set that matches
the new tire set. If the tire pressure select switch is set to the wrong tire
setting, the tire pressure warning system will not operate properly.
After driving for about 20 minutes, the tire pressure warning light
comes on after blinking for 1 minute to indicate a system malfunction.
Tire pressure warning valve and
transmitter ID code settings dis-
play
Press < or > repeatedly until the
setting display appears.
Switching ID codes
Press the “ON/OFF” button to
switch between “MAIN” and
“2ND” ID codes.

nTire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway driving
under dry conditions. Since summer tires do not have the same traction perfor-
mance as snow tires, summer tires are inadequate for driving on snow-covered
or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires
is recommended. When installing snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to provide better traction in snow and to be ade-
quate for driving in most winter conditions, as well as for use year round. All sea-
son tires, however, do not have adequate traction performance compared with
snow tires in heavy or loose snow. Also, all season tires fall short in acceleration
and handling performance compared with summer tires in highway driving.
3Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow tires.
If you need snow tires, select tires of the same size, construction and load capac-
ity as the originally installed tires. Since your vehicle has radial tires as original
equipment, make sure your snow tires also have radial construction. Do not install
studded tires without first checking local regulations for possible restriction.
Snow tires should be installed on all wheels. (→P. 2 0 0 )
nInitializing the tire pressure warning system
Initialize the tires with the tire inflation pressure adjusted to the specified level.
nWhen 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.
lWhen 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.
lAfter carrying out the initialization procedure, the tire pressure warning light
blinks for 1 minute then stays on after driving for about 20 minutes.
