Maintenance and care
AVALON (U)_(OM41440U)
CAUTION
■When the engine is hot
Do not remove the engine coolant reservoir cap or the radiator cap.
(P. 424)
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.

●The needle of the engine coolant temperature gauge ( P. 7 7 )
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.
Follow the correction procedure as described below.
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 sufficient ly, inspect the
hoses and radiator core (radia-
tor) for any leaks.
Radiator
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.

When trouble arises
AVALON (U)_(OM41440U)
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 fans oper ate and to check for coolant leaks
from the radiator or hoses.
The fans operate when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating by checking the
fan sound and air flow. If it is difficult to check these, turn the air condition-
ing system on and off repeatedly. (The fans may not operate in freezing
temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fans are operating:
Have the vehicle in spected 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 fans and belts.
NOTICE
■When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. 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 commercially available coolant additives.
●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.
