Add oil based on the oil level shown on the meter.
Do not add more than 0.5 qt. (0.5 L, 0.4 Imp. qt.) at a time regardless of
the oil level reading.
To check the oil level again, install the oil filler cap by turning it
clockwise.
Check the oil level using the “Oil Level” display and repeat the
above procedure if more oil is required.
Even if the measurement result shows that the oil is below the maximum
level, be careful not to add more oil than necessary.
Install the oil filler cap by turning it clockwise.
■Engine oil consumption
●The amount of engine oil consumed depe nds 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 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 the engine oil has been changed
The “Oil Maintenance” display on the mete r needs resetting. Have the display reset
at your Lexus dealer. ( P. 1 3 2 )

Call your Lexus dealer, service station or auto parts store for information con-
cerning recycling or disposal.

Maintenance and care
CAUTION
■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 burning, get medical atten-
tion 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. Fo llow with milk of magnesia, beaten raw
egg or vegetable oil. Get emergency medical attention immediately.
■When replacing the battery
Use a battery designed for the LFA. Failure to do so may cause gas (hydrogen) to
enter the passenger compartment, causing a fire or explosion.
For replacement of the battery, contact your Lexus dealer.
NOTICE
■Before disconnecting the battery terminal
Turn the ignition switch to the “LOCK” position and check that the gear indicator
turns off before disconnecting the battery terminal.
If the terminal is disconnected while the gear indicator is still displayed, the ASG
(Automated Sequential Gearbox) computer may be negatively affected, possibly
causing the engine not to start. If the term inal is accidentally disconnected while the
indicator is on, contact your Lexus dealer.
■When recharging the battery
Never recharge the battery while the engine is running. Also, be sure all accesso-
ries 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.
■Wheel bolts
Observe the following precautions to reduce the risk of death or serious injury:
●Do not over tighten.
●Never use oil or grease on the wheel bolts.
Oil and grease may cause the wheel bolts to be excessively tightened, leading to
bolt or disc wheel damage. In addition, the oil or grease can cause the wheel bolts
to loosen and the wheel may fall off, causing a serious accident. Remove any oil or
grease from the wheel bolts.
●If there are any cracks or deformations in the wheel bolts, or if the surface treat-
ment becomes worn, have the wheel bolts replaced at your Lexus dealer.
Failure to follow these precautions could cause the wheel bolts to loosen and the
tire to fall off, resulting in death or serious injury.
●If the wheels are frequently removed and installed due to circuit driving etc.,
Lexus recommends periodic changing of the wheel bolts.
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.
