start to run if the air conditioning is on and/or the coolant temperature is high. ( P.357)
■Safety glasses
Wear safety glasses to prevent flying
or falling material, fluid spray, etc. from getting in your eyes.
NOTICE
■If you remove the air cleaner fil-ter
Driving with the air cleaner filter
removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.If the reservoir needs frequent refill-
ing, it may indicate a serious problem.

WARNING
■Used engine oil
●Used engine oil contains poten-
tially harmful contaminants which may cause skin disorders such as inflammation and skin cancer, so

Reservoir cap
“F” line
“L” line
If the level is on or below the “L” line,
add coolant up to the “F” line. ( P.442)
■Coolant selection
Only use “Toyota Super Long Life Cool- ant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-ized water. (Minimum temperature: -
35°C [-31°F])
For more details about coolant, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain cock and water pump.
If you cannot find a leak, have any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer, test the cap and check for leaks in the cooling system.

any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
WARNING
■When the engine is hot
Do not remove the engine coolant
reservoir cap. ( P.443)

the cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
