■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. 153) to change the multi-information dis-
play to blank.
Turn the “ENGINE START STOP” switch to OFF.
Turn the “ENGINE START STOP” switch to IGNITION ON mode with
the trip meter reset button held down.
Keep pressing the button for longer than 7 seconds after the “ENGINE

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 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.
●Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
●Avoid overfilling, or the engine could be damaged.
●Check the oil level on the dipstick every time you refill the vehicle.
●Be sure the engine oil filler cap is properly tightened.

CAUTION
■How to recharge the battery
Only perform a slow charge (5A or less). The battery may explode if charged at a
quicker rate.
■Emergency measures regarding electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immediate medi-
cal attention. If possible, continue to apply water with a sponge or cloth while
traveling to the nearest medical facility.
●If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or a burning sensation, seek
medical attention immediately.
●If electrolyte gets on your clothes
It can soak through clothing on to your skin. Immediately take off the clothing and
follow the procedure above if necessary.
●If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Follow with milk of magnesia, beaten raw
egg or vegetable oil. Get emergency medical attention immediately.
NOTICE
■When recharging the battery
Never recharge the battery while the engine is on. Also, be sure all accessories are
turned off.

CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Doing so may result in an accident, causing death or serious injury.
■When installing the wheel nuts
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened, leading to
bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts
to loosen and the wheel may fall off, causing an accident and resulting in death or
serious injury. Remove any oil or grease from the wheel bolts or wheel nuts.
NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by your Lexus dealer or other
qualified service shop. In addition, make sure to purchase your tire pressure
warning valves and transmitters at your Lexus dealer.
●Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-
genuine wheels.
●Be sure to install the wheel nuts with the
tapered end facing inward. Installing the
nuts with the tapered end facing outward
can cause wheel to break and eventually
cause a wheel to come off while driving,
which could lead to an accident resulting in
death or serious injury.
