4-3. Do-it-yourself maintenance
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 )

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.
