■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.

Maintenance and care
tC_OM_OM21042U_(U)
CAUTION
■
When working near the electric c ooling fans or radiator grille
Vehicles without a smart key system
Be sure the engine switch is off. With the engine switch in the “ON” position,
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.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also, a backfire could cause a fire in the engine com-
partment.

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.

CAUTION
■When the engine is hot
Do not remove the engine coolant 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 strai ght 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 damaging parts or paint.
