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 Section 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
toolsº on page 377 in this Section.
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 advisable.)
Right after driving, the engine
compartmentÐthe engine, radiator,
exhaust manifold, power steering
fluid reservoir and spark plug
boots, etc.Ðwill be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or 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 potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly 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 fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.

Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
NOTICE

Remember that battery and ignition
cable carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.

Add only Toyota Super Long Life
Coolantº or similar high quality eth-
ylene glycol based non- silicate,
non- amine, non- nitrite, and non- bo-
rate coolant with long- life hybrid
organic acid technology to fill the
radiator. Toyota Super Long Life
Coolantº is a mixture of 50% cool-
ant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45%
deionized water (for Canada).

If you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging the parts
or paint.

Do not allow dirt or anything else
to fall through the spark plug holes.

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 iridium- tipped spark
plugs by cleaning or regapping.

Do not overfill automatic transmis-
sion fluid and power steering fluid,
or the transmission and power
steering could be damaged.

Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.

Be careful not to scratch the glass
surface with the wiper frame.

When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.

When jacking up your vehicle with the
jack, position the jack correctly as
shown in the illustrations.
CAUTION
When jacking, be sure to observe the
following to reduce the possibility of
personal injury:
Follow jacking instructions.
Do not put any part of your body
under the vehicle supported by the
jack. 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 Pº.
Block the wheels on the opposite
side of the jack up point if neces-
sary.
Make sure to set the jack properly
in the jack point. Raising the ve-
hicle with jack improperly posi-
tioned will damage the vehicle or
may allow the vehicle to fall off the
jack and cause personal injury.
Never get under the vehicle when
the vehicle is supported by the jack
alone; use vehicle support stands.
Do not raise the vehicle with some-
one in the vehicle.
When raising the vehicle, do not
place any objects on top of or un-
derneath the jack.
NOTICE
Make sure to place the jack correctly,
or your vehicle may be damaged.
Here is a list of parts and tools you will
need to perform do- it- yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
CHECKING THE ENGINE OIL LEVEL
Parts (if level is low):
Toyota Genuine Motor Oilº or equiva-
lent
See page 380 in Section 7- 2 for de-
tails about engine oil selection.
Tools:
Rag or paper towel
Funnel (only for adding oil)
CHECKING THE ENGINE COOLANT
LEVEL
Parts (if level is low):
Toyota Super Long Life Coolantº or
similar high quality ethylene glycol
based non- silicate, non- amine, non- ni-
trite, and non- borate coolant with long-
life hybrid organic acid technology.
Toyota Super Long Life Coolantº is a
mixture of 50% coolant and 50% deion-
ized water (for the U.S.A.) or 55%
coolant and 45% deionized water (for
Canada).

With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick.
1. To get a correct reading, the vehicle
should be on level ground. After turning
off the engine, wait a few minutes for
the oil to drain back into the bottom of
the engine.
2. Pull the dipstick out, hold a rag under
the end and wipe it clean.
3. Reinsert the dipstickÐpush it in as far
as it will go, or the reading will not be
correct.
4. Pull the dipstick out and look at the oil
level while holding a rag under the
end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
NOTICE

Be careful not to drop engine oil on
the vehicle components.

To avoid drops of the engine oil
falling when you pull out the engine
oil dipstick, make sure to hold a
rag under the dipstick.
If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler cap and add engine
oil in small quantities at a time, checking
the dipstick. We recommend that you use
a funnel when adding oil.
The approximate quantity of oil needed to
raise the level between low and full on the
dipstick is indicated below for reference.
When the level reaches within the correct
range, install the filler cap hand- tight.
Oil quantity, L (qt., lmp. qt.):

NOTICE

Be careful not to spill engine oil on
the vehicle components.

Avoid overfilling, or the engine
could be damaged.

Check the oil level on the dipstick
once again after adding the oil.
ENGINE OIL SELECTION
Toyota Genuine Motor Oilº is used in
your Toyota vehicle. Use Toyota approved
Toyota Genuine Motor Oilº or equivalent
to satisfy the following grade and
viscosity.
Oil grade:
API grade SL Energy- Conservingº or
ILSAC multigrade engine oil
Recommended viscosity:
SAE 5W- 30
Outside temperature
SAE 5W- 30 is the best choice for good
fuel economy and good starting in cold
weather.
If SAE 5W- 30 is not available, SAE
10W- 30 may be used. However, it
should be replaced with SAE 5W- 30 at
the next oil change.
