WARNING
■ Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery.
● When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
● Do not allow children near the battery.
NOTICE
■To prevent damaging the vehicle (vehicles with a manual transmission)
Do not pull- or push-start the vehicle, because the catalytic converter may
overheat and become a fire hazard.
■ When handling jumper cables
Be careful that the jumper cables do not become tangled in the cooling fan
or any of the belts when connecting or disconnecting them.

If your vehicle overheats
Correction procedures
Stop the vehicle in a safe place and turn off the air condition-
ing system, 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 (radiator) for any leaks.
Gasoline engine
Radiator
Cooling fan
If a large amount of coolant leaks,
immediately contact any autho-
rized Toyota dealer or repairer, or
another duly qualified and
equipped professional.
The following may indicate that your vehicle is overheating.
●The high engine coolant temperature warning light (P. 536)
comes on or flashes, or a loss of engine power is experienced.
(For example, the vehicle speed does not increase.)
● Steam comes out from under the hood.

Diesel engine
Radiator
Cooling fans
If a large amount of coolant leaks,
immediately contact any autho-
rized Toyota dealer or repairer, or
another duly qualified and
equipped professional.
The coolant level is satisfactory if
it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL”
“LOW”
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
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
immediately 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 temperatures.)

If the fan is not operating:
Stop the engine immediately and contact any authorized
Toyota dealer or repairer, or another duly qualified and
equipped professional.
If the fan is operating:
Have the vehicle inspected at the nearest any authorized
Toyota dealer or repairer, or another duly qualified and
equipped professional.
WARNING
■ 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 injuries such as burns.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fans and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● When the electric cooling fan may operate even after the engine has been
stopped (diesel engine only).
 P. 439
● 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.

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 any coolant additive.
