■Engine coolant reservoir
The coolant level is satisfactory if it
is between the “FULL” and “LOW”
lines on the reservoir when the
engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW”
line, add coolant up to the “FULL” line.

The coolant level is satisfactory if it
is between the “F” and “L” lines on
the reservoir when the engine is
cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L” line,
add coolant up to the “F” line. ( P.560)
■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.
NOTICE
■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

■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the fol-
lowing precautions before recharging:
●If recharging with the battery installed
on the vehicle, be sure to disconnect the ground cable.
●Make sure the charger is off when connecting and disconnecting the
charger cables to the battery.
■After recharging/reconnecting the
battery (vehicles with a smart entry & start system)
●Unlocking the doors using the smart entry & start system may not be possi-

■When the engine is hot
Do not remove the engine coolant
reservoir cap and the intercooler cool- ant reservoir cap.
The cooling system may be under
pressure and may spray hot coolant if 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.
■If you spill coolant
Be sure to wash it off with water to
prevent it from damaging parts or
paint.

area. Do not charge the battery in a garage or closed room where there is
insufficient ventilation.
■Emergency measures regarding electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible,
continue to apply water with a sponge or cloth while traveling to
the nearest medical facility.

WA R N I N G
■When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer
fluid contains alcohol and may catch
fire if spilled on the engine, etc.
NOTICE
■Do not use any fluid other than
washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the
vehicle’s painted surfaces, as well as damaging the pump leading to prob-
lems of the washer fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as nec-
essary.
Refer to the freezing temperatures listed on the label of the washer fluid
bottle.
