Jump-Starting
Jump-starting is dangerous if done incorrectly. So follow the proce-
dure carefully. If you feel unsure about jump-starting, we strongly rec-
ommend that you have a competent service technician do the work.Remove the battery cover.
Make sure the booster battery is 12 V and that its negative terminal
is grounded.
If the booster battery is in another vehicle, do not allow both vehi-
cles to touch. Turn off the engine of the vehicle with the booster bat-
tery and all unnecessary electrical loads in both vehicles.

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).

6-4. Emergency Starting
Starting a Flooded Engine
Follow this procedure:If the engine does not start within five seconds on the first try, wait
ten seconds and try again.
Make sure the parking brake is on.
Depress the accelerator all the way and hold it there.
Depress the clutch pedal (Manual transaxle) or the brake pedal
(Automatic transaxle), then pres s the push button start. If the
engine starts, release the accele rator immediately because the
engine will suddenly rev up.
If the engine fails to start, crank it without depressing the accelera-
tor.
If the engine still does not start using the above procedure, have your
vehicle inspected by your Toyota dealer.
If the engine fails to start, it may be flooded (excessive fuel in
the engine).

Push-Starting
Do not push-start your Toyota.
You cannot start a vehicle with an automatic transaxle by pushing it.
WARNING
■Never tow a vehicle to start it
Towing a vehicle to start it is dangerous. The vehicle being towed could
surge forward when its engine starts, causing the two vehicles to collide.
The occupants could be injured.
NOTICE
Do not push-start a vehicle that has a manual transaxle. It can damage the
emission control system.

6-5. Overheating
Overheating
If the high engine coolant temperature warning light turns on:Drive safely to the side of the road and park off the right-of-way.
Put a vehicle with an automatic tr ansaxle in park (P), a manual tran-
saxle in neutral.
Apply the parking brake.
Turn off the air conditioner.
Check whether coolant or steam is escaping from the engine com-
partment.
If 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.
If 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 system cap
Coolant reservoir
If the high engine coolant temperature warning light turns on,
the vehicle loses power, or you hear a loud knocking or pinging
noise, the engine is probably too hot.

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.

6-6. Emergency Towing
Towing Description
A towed vehicle usually should
have its drive wheels (front
wheels) off the ground. If exces-
sive damage or other conditions
prevent this, use wheel dollies.
When towing with the rear wheels
on the ground, release the parking
brake.
We recommend that towing be done only by your Toyota dealer
or a commercial tow-truck service.
Proper lifting and towing are necessary to prevent damage to
the vehicle. Government and local laws must be followed.
Wheel dollies
NOTICE
● Do not tow the vehicle pointed back-
ward with driving wheels on the ground.
This may cause internal damage to the
transaxle.
● Do not tow with sling-type equipment.
This could damage your vehicle. Use
wheel-lift or flatbed equipment.

The hook positioned under the
rear bumper on the right side is for
tying down the vehicle during
transport, and it cannot be used
for towing other vehicles.
It can be used as a towing hook
only when the vehicle must be
towed by another vehicle in an
emergency case such as when
the vehicle is stuck in snow, how-
ever, it may damage the bumper.
NOTICE
●Do not use excessive force as it may damage the cap or scratch the
painted bumper surface.
● If the tiedown eyelet is not securely tightened, it may loosen or disengage
from the bumper when tying the vehicle. Make sure that the tiedown eyelet
is securely tightened to the bumper.
Tiedown Hook-Rear
Tiedown hook
NOTICE
When using the hook in such emergency cases, observe the following so as
not to damage the tiedown hook or the vehicle body.
●The vehicle must be pulled straight to the rear so that no load is applied to
the vehicle in the lateral direction.
● The bumper may be damaged if the tie down hook is used as a towing
hook.
● When using a metal chain or wire cable, wrap a cloth around the attach-
ment area. If the metal chain or wire cable contacts the bumper directly,
the bumper could be scratched or damaged.
