jacking positions recommended in this manual.
■Do not jack up the vehicle in a position other than the designated
jack-up position or place any objects on or under the jack
Jacking up the vehicle in a position other than the designated jack-up
position or placing objects on or under the jack is dangerous as it could

Using a jack that is not designed for your Toyota is dangerous. The vehi-
cle could slip off the jack and seriously injure someone.

Jacking up the vehicle higher than is necessary is dangerous as it could
destabilize the vehicle resulting in an accident.
■Do not start the engine or shake the vehicle while it is jacked up

ous as it could cause the vehicle to fa ll off the jack resulting in an acci-
dent.

WARNING
■Make sure the mounting surfaces of the wheel, hub and lug nuts
are clean before changing or replacing tires
When changing or replacing a tire, not removing dirt and grime from the
mounting surfaces of the wheel, hub and hub bolts is dangerous. The
lug nuts could loosen while driving a nd cause the tire to come off, result-
ing in an accident.
■Do not apply oil or grease to lug nuts and bolts and do not tighten
the lug nuts beyond the recommended tightening torque
Applying oil or grease to lug nuts and bolts is dangerous. The lug nuts
could loosen while driving and cause the tire to come off, resulting in an
accident. In addition, lug nuts and bolts could be damaged if tightened
more than necessary.
■Always securely and correctly tighten the lug nuts
Improperly or loosely tightened lug nuts are dangerous. The wheel
could wobble or come off. This could result in loss of vehicle control and
cause a serious accident.
■Be sure to reinstall the same nuts you removed or replace them
with metric nuts of the same configuration
Because the wheel studs and lug nuts on your Toyota have metric
threads, using a non-metric nut is dan gerous. On a metric stud, it would
not secure the wheel and would damage the stud, which could cause
the wheel to slip off and cause an accident.
■Do not drive with any tires that have incorrect air pressure
Driving on tires with incorrect air pressure is dangerous. Tires with
incorrect pressure could affect handling and result in an accident. When
you check the regular tires’ air pressure, check the spare tire, too.

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 (+) term inal 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 fr om 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
system, and other electrical parts beyond repair with a 24 V power supply
(two 12 V batteries in series or a 24 V motor generator set).

If Trouble Arises
■If you find no problems, the engine is cool, and no leaks are
obvious:
Carefully add coolant as required (→P. 425).
WARNING
■ Pull over to a safe location, then switch the ignition to off and
make sure the fan is not running befo re 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.
