Canada:
“Toyota Super Long Life Coolant” is

deionized water. (Minimum tem-
perature: -44°F [-42°C])
For more details about coolant, con-
tact your Toyota dealer.
■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 your 
Toyota dealer test the cap and 
check for leaks in the cooling sys-
tem.
Check the radiator and con- denser and clear away any for-
eign objects. If either of the 
above parts is extremely dirty or 
you are not sure of their condi-
tion, have your vehicle 
inspected by your Toyota dealer.
■Checking fluid level
The brake fluid level should be 
between the “MAX” and “MIN” 
lines on the tank.
WARNING
■When the engine is hot
Do not remove the engine coolant 
reservoir cap. ( P.363)
The cooling system may be under 
pressure and may spray hot cool-
ant 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 d amaging parts or 
paint.
Checking the radiator and 
condenser
WARNING
■When the engine is hot
Do not touch the radiator or con-
denser as they may be hot and 
cause serious injuries, such as 
burns.

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 lead-
ing to problems of the washer 
fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as 
necessary.
Refer to the freezing tempera-
tures listed on the label of the 
washer fluid bottle.
