CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-

injury, observe the following precautions.
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted
surfaces. If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience disc omfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 549)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from get-
ting in your eyes.

■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.

diately.
NOTICE
■When recharging the battery
Never recharge the battery while the engine is operating. Also, be sure all acces-
sories are turned off.
■When adding distilled water
Avoid overfilling. Water spilled during battery recharging may cause corrosion.
■When replacing the battery
Replace the battery with a battery of the same size.
Installing a battery of a different size will prevent the cover from being properly
installed over the battery. This may cause water to enter the engine compartment
when it rains or the vehicle is washed, resulting in a malfunction.
For more information about replacing the battery, contact your Lexus dealer.
