the electric cooling fans may automatically start to run if the air conditioning
is on and/or the coolant temperature is high. ( P. 303)
Vehicles with a smart key system
Be sure the “ENGINE START STOP” switch is off. With the “ENGINE START
STOP” switch in IGNITION ON mode, the electric cooling fans may automat\
-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 303)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting your eyes.

Engine coolant
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. (P. 413)
■Coolant selection
Only use “Toyota Super Long Life Coolant” 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.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Minimum temperature: -31 F [-35 C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Minimum temperature: -44 F [-42 C])
For more details about engine coolant, contact your Scion 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 Scion dealer test the cap and check for
leaks in the cooling system.
