CAUTION
■When working near the electric cooling fan 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 fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 442)
Vehicles with a smart key system: Be sure the engine switch is off. With the
engine switch in IGNITION ON mode, the electric cooling fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 442)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in 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.

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. 537)
■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.
For the U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% cool-
ant and 50% deionized water. (Minimum temperature: -31F
[-35C])
For Canada: “Toyota Super Long Life Coolant” is a mixture of 55% cool-
ant and 45% deionized water. (Minimum temperature: -44F
[-42C])
For more details about engine coolant, contact 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 system.

Maintenance and care

CAUTION
■When the engine is hot
Do not remove the engine coolant reservoir cap or the radiator cap.
(P. 538)
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.

●Vehicles without a multi-information display: The high engine cool-
ant temperature warning light (P. 492) comes on or a loss of
power is experienced.
Vehicles with a multi-information display: The engine coolant tem-
perature gauge (P. 82) enters the red zone or a loss of power is
experienced.
●Steam comes out from under the hood.
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks.

Cooling fan
If a large amount of coolant
leaks, immediately contact your
Toyota dealer.
The coolant level is satisfactory
if it is between the “F” and “L”
lines on the reservoir.

5388-2. Steps to take in an emergency
COROLLA_TMMMS_TMMC_U (OM12F00U)
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is unavail-
able.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fan operate and to check for coolant leaks
from the radiator or hoses.
The fan operates when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fan is operating by checking the fan
sound and air flow. If it is difficult to check these, turn the air conditioning
system on and off repeatedly. (The fan may not operate in freezing temper-
atures.)
If the fan is not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fan is operating:
Have the vehicle inspected at the nearest Toyota dealer.

CAUTION
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
●Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts.

●Do not loosen the radiator cap and the
coolant reservoir cap while the engine
and radiator are hot.
High temperature steam or coolant
could spray out.
