Radiator and condenserCheck the radiator and condenser and remove any foreign objects.
If any of the above parts are extr emely dirty or you are not sure of
their condition, have your vehicl e checked by your Toyota dealer.
Brake fluid
■ Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
NOTICE
■When adding engine coolant
Coolant is neither plain water nor stra ight 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 damage to parts or paint.
CAUTION
■When the engine is hot
Do not touch the radiator or condenser, as they may be hot and may cause
burns.

5-2. Steps to take in an emergency
If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam: Stop the engine. Carefully lift the hood after the steam
subsides and then restart the engine.
If you do not see steam: Leave the engine running and carefully lift the hood.
Check to see if the cooling fans are operating.
If the fans are operating: Wait until the temperature of the engine (shown on the
instrument cluster) begins to fall and then stop the
engine.
If the fans are not operating: Stop the engine and call your Toyota dealer.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.STEP 1

Overheating
If you observe the following, your vehicle may be overheating.
●The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
● Steam is coming from under the hood.
CAUTION
■To prevent an accident or injury when inspecting under the hood of
your vehicle
●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, caus-
ing serious injury such as burns.
● Keep hands and clothing away from the fan and other belts while the
engine is running.
● Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable.
(P. 428)
Have the vehicle chec ked at the nearest Toyota dealer as soon as
possible.
