If Trouble Arises
WARNING
■ Follow These Precautions Carefully
To ensure safe and correct handling of the battery, read the following pre-
cautions carefully before using the battery or inspecting it.
■ Do not allow the positive (+) terminal to contact any other metal
object that could cause sparks
Flames and sparks near open battery cells are dangerous. Hydrogen gas,
produced during normal battery operation, could ignite and cause the bat-
tery to explode. An exploding battery can cause serious burns and injuries.
When working near a battery, do not allow metal tools to contact the positive
(+) or negative (-) terminal of the battery.
■ Keep all flames, including cigarettes, and sparks away from
open battery cells
Flames and sparks near open battery cells are dangerous. Hydrogen gas,
produced during normal battery operation, could ignite and cause the bat-
tery to explode. An exploding battery can cause serious burns and injuries.
■ Do not jump-start a frozen battery or one with a low fluid level
Jump-starting a frozen battery or one with a low fluid level is dangerous. It
may rupture or explode, causing serious injury.
■ Connect the negative cable to a good ground point away from the bat-
tery
Connecting the end of the second jumper cable to the negative (-) terminal
of the discharged battery is dangerous.
A spark could cause the gas around the battery to explode and injure some-
one.
■ Route the jumper cables away from parts that will be moving
Connecting a jumper cable near or to moving parts (cooling fans, belts) is
dangerous. The cable could get caught when the engine starts and cause
serious injury.
NOTICE
Use only a 12 V booster system. You can damage a 12 V starter, ignition sys-
tem, and other electrical parts beyond re pair with a 24 V power supply (two 12
V batteries in series or a 24 V motor generator set).

6-5. Overheating
Overheating
If the high engine coolant temperature warning light illuminates:
Drive safely to the side of the road and park off the right-of-way.
Put a vehicle with an automatic transaxle in park (P), a manual
transaxle in neutral.
Apply the parking brake.
Turn off the air conditioner.
Check whether coolant or steam is escaping from the engine com-
partment.
XIf steam is coming from the engine compartment:
Do not go near the front of the vehicle. Stop the engine.
Wait until the steam dissipates, then open the hood and start the
engine.
XIf neither coolant nor steam is escaping:
Open the hood and idle the engine until it cools.
Make sure the cooling fan is operating, then turn off the engine after
the temperature has decreased.
When cool, check the coolant level.
If it is low, look for coolant leaks from the radiator and hoses.
■If you find a leak or other damage, or if coolant is still leaking:
Stop the engine and call your Toyota dealer.Cooling fan
Cooling system cap
Coolant reservoir
If the high engine coolant temperature warning light illuminates,
the vehicle loses power, or you hear a loud knocking or pinging
noise, the engine is probably too hot.

5036-5. Overheating
6
If Trouble Arises
■If you find no problems, the engine is cool, and no leaks are
obvious:
Carefully add coolant as required (→P. 431).
WARNING
■ Switch the ignition to off and make sure the fan is not running
before attempting to work near the cooling fan
Working near the cooling fan when it is running is dangerous. The fan could
continue running indefinitely even if the engine has stopped and the engine
compartment temperature is high. You could be hit by the fan and seriously
injured.
■ Do not remove either cooling system cap when the engine and
radiator are hot
When the engine and radiator are hot, scalding coolant and steam may
shoot out under pressure and cause serious injury.
■ Open the hood ONLY after steam is no longer escaping from the engine
Steam from an overheated engine is dangerous. The escaping steam could
seriously burn you.
NOTICE
●If the cooling fan does not operate while the engine is running, the engine
temperature will increase. Stop the engine and call your Toyota dealer.
● If the engine continues to overheat or frequently overheats, have the cool-
ing system inspected. The engine could be seriously damaged unless
repairs are made. Consult your Toyota dealer.
