This air conditioning system has a high
efficient air refiner filter which helps
eliminate dust and pollen, thereby in-
creasing your driving comfort.
The air conditioning filter is set behind
the glove box.
The air conditioning filter may clog after
long use. The filter may need to be re-
placed if the air flow of the air conditioner
and heater experiences extreme reductions
in operating efficiency, or if the windows
begin to fog up easily.Perform filter replacement periodically.
Period of replacement (expected):
For U.S.A.—Every 30000 miles
For Canada—Every 16000 km
NOTE: This is the normal maintenance
period. This may change depending on
operating conditions.
If the symptoms of air conditioning
efficiency problems occur, contact your
Toyota dealer to have the filter checked
and replaced.
(Actual replacement time: Less than 10
minutes approximately)
NOTICE
Do not try to replace the air condi-
tioning filter by yourself. Doing so
may damage the vehicle.
INFORMATION
The air filter should be installed prop-
erly in position. The use of air condi-
tioning with the air filter removed
may cause deteriorated dustproof per-
formance and then affect air condi-
tioning performance.

Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
NOTICE
Do not use organic substances (gaso-
line, kerosene, benzine or strong sol-
vents), which may be toxic or cause
damage.
3. Rinse thoroughly—dried soap cancause streaking. In hot weather you
may need to rinse each section right
after you wash it.
4. To prevent water spots, dry the vehicle using a clean soft cotton towel. Do not
rub or press hard—you might scratch
the paint.
Automatic car wash
Your vehicle may be washed in an auto-
matic car wash, but remember that the
paint can be scratched by some types of
brushes, unfiltered washing water, or the
washing process itself. Scratching reduces
paint durability and gloss, especially on
darker colors. The manager of the car
wash should be able to advise you wheth-
er the process is safe for the paint on
your vehicle. Waxing your Toyota
Polishing and waxing is recommended
to maintain the original beauty of your
Toyota’s finish.
Apply wax once a month or if the vehicle
surface does not repel water well.
1. Always wash and dry the vehicle be- fore you begin waxing, even if you are
using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become extremely weath-
ered, use a carcleaning polish, fol-
lowed by a separate wax. Carefully fol-
low the manufacturer ’s instructions and
precautions. Be sure to polish and wax
the chrome trim as well as the paint.
3. Wax the vehicle again when water does not bead but remains on the sur-
face in large patches.
NOTICE
Always remove the plastic bumpers if
your vehicle is repainted and placed
in a high heat paint waxing booth.
High temperatures could damage the
bumpers.
CAUTION
Be careful not to splash water or
spill liquid on the floor. This may
prevent the side airbags from acti-
vating correctly, resulting in serious
injury.
Do not wash the vehicle floor with
water, or allow water to get onto
the floor when cleaning the vehicle
interior or exterior. Water may get
into audio components or other
electrical components above or un-
der the floor carpet (or mat) and
cause a malfunction; and it may
cause body corrosion.
Vinyl interior
The vinyl upholstery may be easily
cleaned with a mild soap or detergent
and water.

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 doityourself 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
ityourself maintenance, see “Parts and
tools” 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
compartment—the engine, radiator,
exhaust manifold and spark plug
boots, etc.—will 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
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. “Toyota Super Long Life
Coolant” 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.
 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.
 Do not overfill automatic transmis-
sion fluid, or the transmission
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.
