Maintenance and care
■If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, intercooler
coolant reservoir cap (if equipped), 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.
Check the radiator, condenser and intercooler coolant radiator/inter-
cooler and clear away any foreign objects. If any of the above parts is
extremely dirty or you are not sure of their condition, have your vehi-
cle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
WARNING
■ When the engine is hot
Do not remove the radiator cap (if equipped), the engine coolant reservoir
cap or intercooler coolant reservoir cap (if equipped).
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 mixture 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.
■ Notice on coolant quality
Do not use improper coolant. If improper coolant is used, the engine cooling
system may be damaged.
Radiator, condenser and intercooler coolant radiator/intercooler
(if equipped)
WARNING
■ When the engine is hot
Do not touch the radiator, condenser or intercooler coolant radiator/inter-
cooler as they may be hot and cause serious injuries, such as burns.

Add washer fluid in the following
situations:
● A washer does not work.
● The warning message appears
on the multi-information display
(if equipped).
NOTICE
■ When recharging the battery
Never recharge the battery while the engine is running. Also, be sure all
accessories are turned off.
■ When adding distilled water (vehicles with maintenance type battery)
Avoid overfilling. Water spilled duri ng battery recharging may cause corro-
sion.
Washer fluid
WARNING
■ When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid
contains alcohol and may catch fi re 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 problems of the washer fluid not spraying.
■ Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures list ed on the label of the washer fluid bot-
tle.

Maintenance and care
You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer. Even if
you decide to drain it yourself, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
The water in the fuel filter needs to be drained if one of the following
symptoms occurs:
Vehicles without multi-information display
When the fuel system warning light flashes and a buzzer sounds.
( P. 569)
Vehicles with multi-information display
When “Water accumulation in fuel filter See owner’s manual” is
shown on the multi-information display and a buzzer sounds*1.
Vehicles without smart entry & start system: Turn the engine switch
to the “LOCK” position.
Vehicles with smart entry & start system: Turn the engine switch off.
Place a small tray under the drain plug or drain hose to catch the
water and any fuel that comes out.
Perform the draining as shown in the illustration.
Turn the drain plug counter-
clockwise about 2 to 2 1/2
turns.
Loosening more than this will
cause water oozing from around
the drain plug.
Operate the priming pump
until fuel begins to run out.
After draining, tighten the drain plug by hand.
