If the engine speed does not increase
when the accelerator pedal is de-
pressed, the electronic throttle control
system may be faulty. Move the vehicle
to a safe place by means of creeping
and call a Toyota dealer for assistance:1. Depress the brake pedal and shift to the “D” position.
2. Gradually release the brake pedal, and the vehicle starts to move by creeping.
After arriving at a safe place, stop the
vehicle and call a Toyota dealer for
assistance.
CAUTION
The above method of moving the
vehicle is for emergency. Use it
only for moving minimum distances
to a safe place.
Be especially careful to prevent er-
roneous pedal operation.
If your vehicle overheats
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in “P”
and apply the parking brake. Turn off
the air conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Visually check to see if the enginedrive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or thecoolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as-
sistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
If you cannot incr ease the en-
gine speed

CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperaturehas cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Toyota dealer.
If you have a flat tire—
1. Reduce your speed gradually, keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in “P”.
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury:
Follow jacking instructions.
 Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.
 Do not start or run the engine
while your vehicle is supported
by the jack.
 Stop the vehicle on a level firm
ground, firmly set the parking
brake and put the transmission
in reverse. Block the wheel di-
agonally opposite to the one
being changed if necessary.

quate ventilation if you run the en-
gine.
IN THE ENGINE COMPARTMENT
Items listed below should be checked
from time to time, e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See page 314 for additional informa-
tion. Engine coolant level
Make sure the coolant level is between
the “FULL” and “LOW” lines on the see
−
through reservoir when the engine is cold.
See page 296 for additional information.
Radiator, condenser and hoses
Check that the front of the radiator and
condenser are clean and not blocked with
leaves, dirt, or insects. See page 297 for
additional information.
Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower lev-
el lines on the case. Add only distilled
water when replenishing. See page 310 for
additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See page 298 for additional information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level ground. See page 294 for addi-
tional information.
Power steering fluid level
Check the level through the reservoir. The
level should be in the “HOT” or “COLD”
range depending on the fluid temperature.

If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this section.
You should be aware that improper or in-
complete servicing may result in operating
problems.
Performing do−it−yourself maintenance
during the warranty period may affect your
warranty coverage. Read the separate
Toyota Warranty statement for details and
suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Section 6,
there are still a number of items that must
be done by a qualified technician with
special tools.
For information on tools and parts for do −
it −yourself maintenance, see “Parts and
tools” on page 291.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:CAUTION
When the engine is running,
keep hands, clothing, and tools
away from the moving fan and
engine drive belts. (Removing
rings, watches, and ties is advis-
able.)
Right after driving, the engine
compartment—the engine, radia-
tor, exhaust manifold, power
steering fluid reservoir and spark
plug boots, etc.—will be hot. So
be careful not to touch them.
Oil, fluids and spark plugs may
also be hot.
If the engine is hot, do not re-
move the radiator cap or loosen
the drain plugs to prevent burn-
ing yourself.
Do not smoke, cause sparks or
allow open flames around fuel or
the battery. Their fumes are flam-
mable.
Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
Do not get under your vehicle
with just the body jack support-
ing it. Always use automotive
jack stands or other solid sup-
ports.

Be sure that the ignition is off if
you work near the electric cool-
ing fan or radiator grille. With
the ignition on, the electric cool-
ing fan will automatically start to
run if the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to
flying or falling material, fluid
spray, etc.
Used engine oil contains poten-
tially harmful contaminants which
may cause skin disorders such
as inflammation or skin cancer,
so care should be taken to avoid
prolonged and repeated contact
with it. To remove used engine
oil from your skin, wash thor-
oughly with soap and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter
only in a safe and acceptable
manner. Do not dispose of used
oil and filter in household trash,
in sewers or onto the ground.
Call your dealer or a service sta-
tion for information concerning
recycling or disposal.
NOTICE
Remember that battery and ignition
cables carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.
 Add only “Toyota Super Long Life
Coolant” or similar high quality eth-
ylene glycol based nonsilicate,
nonamine, nonnitrite and nonbo-
rate coolant with longlife hybrid
organic acid technology to fill the
radiator. And if you spill some of
the coolant, be sure to wash it off
with water to prevent it from dam-
aging the parts or paint.
 Do not allow dirt or anything else
to fall through the plug holes.
 Do not pry the outer electrode of a
spark plug against the center elec-
trode.
 Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
 Do not reuse iridiumtipped spark
plugs by cleaning or regapping.

Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SL. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W−30. “Energy −
Conserving” shown in the lower portion,
indicates that the oil has fuel −saving ca-
pabilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.
To ensure excellent lubrication perfor-
mance for your engine, “Toyota Genuine
Motor Oil” is available, which has been
specifically tested and approved for all
Toyota engines.
Please contact your Toyota dealer for fur-
ther details about “Toyota Genuine Motor
Oil”. Look at the seethrough coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the “FULL” and “LOW” lines on the
reservoir. If the level is low, add the
coolant. (For the coolant type, see
“Coolant type selection” described be-
low.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the “LOW” line, add
coolant. Bring the level up to the “FULL”
line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
