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.

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.

Wa r n i n g m e s s a g eDetailsCorrection procedure
Indicates that engine oil
level is low.
Check the level of engine
oil, and add if necessary.
(U.S.A. only)
Indicates that the engine
oil is scheduled to be
changed.
Check the engine oil, and
change if necessary.
Comes on approximately
4500 miles (7200 km)

changed. (The indicator
will not work properly
unless the oil mainte-
nance data has been
reset.)
(U.S.A. only)
Indicates that the engine
oil should be changed.
Check and change the
engine oil.
Comes on approximately
5000 miles (8000 km)
after the engine oil is
changed (and the oil

5-2. Steps to take in an emergency
nThe compact spare tire
lThe compact spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
Use the compact spare tire temporarily only in an emergency.
lMake sure to check the tire pressure of the compact spare tire. (→P. 43 9 )
nWhen using the compact spare tire
As the compact spare tire is not equipped with the tire pressure warning valve and
transmitter, low inflation pressure of the spare tire will not be warned. Also, if you
replace the compact spare tire after the tire pressure warning light comes on, the
light remains on.
nIf you have a flat rear tire on a road covered with snow or ice
Install the compact spare tire on the front of the vehicle. Perform the following steps
and fit tire chains to the rear tires.
Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of the vehi-
cle.
Fit tire chains to the rear tires.
nAfter completing the tire change
The tire pressure warning system must be reset. (→P. 3 2 7 )
