Maintenance and care
Check the radiator, condenser and intercooler and clear away any for-
eign objects.
If any of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
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.
Radiator, condenser and intercooler
CAUTION
When the engine is hot (except hybrid model)
Do not touch the radiator, condenser or intercooler as they may be hot and
cause serious injuries, such as burns.
When the hybrid system is hot (hybrid model)
Do not touch the radiator or condenser as they may be hot and cause seri-
ous injuries, such as burns.

Vehicles without a multi-information display: The high engine cool-
ant temperature warning light (P. 614) comes on or a loss of
engine power is experienced. (For example, the vehicle speed
does not increase.)
Vehicles with a multi-information display: The engine coolant tem-
perature gauge (P. 128) enters the red zone or a loss of engine
power is experienced. (For example, the vehicle speed does not
increase.)
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.

When trouble arises
The coolant level is satisfactory if it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL”
“LOW”
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 operates 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 tem-
peratures.)

If the fan is not operating:
Stop the engine immediately and contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
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. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
High temperature steam or coolant could spray out.
NOTICE
When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
To prevent damage to the cooling system
Observe the following precautions:
Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
Do not use any coolant additive.

enced. (For example, the vehicle speed does not increase.)
“HYBRID SYSTEM OVERHEAT” is shown on the multi-information
display.

If the high engine coolant temperature is shown on the multi-
information display
Stop the vehicle in a safe place and turn off the air conditioning
system, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:

tor core (radiator) for any
leaks.
