CAUTION
■When installing a child restraint system
Follow the directions given in the child restraint system installation manual and fix
the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other passen-
gers may be injured or even killed in the event of sudden braking, sudden swerving
or an accident.
●When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child's shoulder. The belt should be kept away
from the child's neck, but not so that it could fall off the child's shoulder. Failing to
do so may result in death or serious injury in the event of sudden braking, sudden
swerving or an accident.
●Make sure the outside rear seat head restraints are not in the folded position.
●Ensure that the belt and tab are securely locked and the seat belt is not twisted.
●Push and pull the child seat from side to side and forward to be sure it is secure.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provided by the child restraint system manufac-
turer.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat.
●Only put a forward facing or booster child
seat on the front seat when unavoidable.
When installing a forward facing or
booster child seat on the front passenger
seat, move the seat as far back as possible
even if the “AIR BAG OFF” indicator light is
illuminated. Failing to do so may result in
death or serious injury if the airbags deploy
(inflate).

CAUTION
■Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the seat belt
will not securely hold the child restraint system, which could cause death or serious
injury to the child or other passengers in the event of sudden braking, sudden
swerving or an accident.
■To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects around
the anchors and that the seat belt is not caught behind the child restraint system.
Make sure the child restraint system is securely attached, or it may cause death or
serious injury to the child or other passengers in the event of a sudden stop, sudden
swerve or accident.

Maintenance and care
IS350/250_U
■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/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 oil change system should be reset. Perform the following procedures: Switch the display to the odometer ( →P. 151) 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 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
■Used engine oil
●Used 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.
●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.
