Maintenance facts
Regular maintenance is essential.
We urge you to protect your new vehicle
by having your Toyota serviced according
to the maintenance schedule given in the
separate booklet. Regular maintenance will
aid:
DGood fuel economy
DLong vehicle life
DDriving enjoyment
DSafety
DReliability
DWarranty coverage
DCompliance with government regula-
tions
Your Toyota has been designed for eco-
nomical driving and economical mainte-
nance. Many formerly required mainte-
nance items are no longer required or are
not required as often. To make sure your
vehicle runs at peak efficiency, follow the
maintenance schedule.
For full details of your maintenance
schedule, read the separate “Toyota
Service Booklet” or “Toyota Warranty
Booklet”.Where to go for service?
In order to maintain your vehicle in the
highest possible condition, Toyota
recommends that all repairs and service
operations are carried out by authorized
Toyota dealers or repairers or other duly
qualified and equipped professionals. For
repairs and services covered by your
warranty, please visit an authorized Toyota
dealer or repairer, who will use genuine
Toyota parts in repairing any difficulties
you may encounter. There can also be
advantages to utilizing authorized Toyota
dealers or repairers for non−warranty
repairs and services, as due to their
specialization in working with Toyota
vehicles, members of the Toyota network
will be able to expertly assist you with
any difficulties you may encounter.
Your Toyota dealer or repairer, or another
duly qualified and equipped professional
service department will perform all of the
scheduled maintenance on your ve-
hicle—reliably and economically.
What about do−it−yourself maintenance?
Many of the maintenance items are easy
to do yourself if you have a little mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form them are presented on page 257 in
Section 7.

MAINTENANCE REQUIREMENTS255
Note, however, that some maintenance
tasks require special tools and skills.
These are best performed by qualified
technicians. Even if you’re an experienced
do−it−yourself mechanic, we recommend
that repairs and maintenance be
conducted by an authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional. Any authorized
Toyota dealer or repairer will keep a
record of maintenance, which could be
useful should you ever require Warranty
Service. Should you choose to select a
qualified and equipped professional other
than an authorized Toyota repairer to
service or maintain your vehicle, we
recommend that you request that a record
of maintenance be kept.
The service interval for scheduled main-
tenance is determined by the odometer
reading or time interval, whichever
comes first, shown in the schedule.
Rubber hoses (for cooling and heater
system, brake system and fuel system)
should be inspected by a qualified tech-
nician in accordance with the Toyota
maintenance schedule.
They are particularly important mainte-
nance items. Have any deteriorated or
damaged hoses replaced immediately.
Note that rubber hoses will deteriorate
with age, resulting in swelling, chafing or
cracks.Be on the alert for changes in perfor-
mance, sounds, and visual tip−offs that
indicate service is needed. Some impor-
tant clues are as follows:
DEngine missing, stumbling, or pinging
DAppreciable loss of power
DStrange engine noises
DA leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
DChange in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaustsystem checked im-
mediately.)
DFlat−looking tire; excessive tire squeal
when cornering; uneven tire wear
DVehicle pulls to one side when driving
straight on a level road
DStrange noises related to suspension
movement
DLoss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
DEngine coolant temperature continually
higher than normal
If you notice any of these cues, take your
vehicle to any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional, as soon as pos-
sible. It probably needs adjustment or re-
pair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.

260DO−IT−YOURSELF MAINTENANCE: Introduction
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.
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.
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
DWhen 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.)
DRight after driving, the engine
compartment—the engine, radiator,
exhaust manifold, and spark plug
boots, etc. —will be hot. So be
careful not to touch them. Oil,
fluids and spark plugs may also be
hot.
DIf the engine is hot, do not remove
the radiator cap or coolant reser-
voir cap or loosen the drain plugs,
to prevent burning yourself.
DDo not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
DDo not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
DBe extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
DDo not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
DBe sure that the engine is off if you
work near the electric cooling fan
or radiator grille. With the engine
on, the electric cooling fan will au-
tomatically start to run if the en-
gine coolant temperature is high
and/or the air conditioning is on.
DUse eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
DUsed 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.
DDo not leave used oil within the
reach of children.
DDispose 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.
DTake care when filling the brake
fluid reservoir because brake fluid
can harm your hands or eyes. If
fluid gets on your hands or in your
eyes, flush the affected area with
clean water immediately. If you still
feel uncomfortable with your hands
or eyes, go to the doctor.

precautions

DO−IT−YOURSELF MAINTENANCE: Introduction261
NOTICE
zRemember that battery and ignition
cables carry high currents or volt-
ages. Be careful not to accidentally
cause a short circuit.
zAdd only “Toyota Super Long Life
Coolant” 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
Coolant” is a mixture of 50% cool-
ant and 50% deionized water.
zIf you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging any parts
or paint.
zDo not allow dirt or anything else
to fall through the spark plug holes.
zDo not pry the outer electrode of a
spark plug against the center elec-
trode.
zUse only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
zIf you spill brake fluid, be sure to
wash it off with water to prevent it
from damaging any parts or paint.
zDo not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
zBe careful not to scratch the glass
surfaces with the wiper frames.
zWhen closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.

262DO−IT−YOURSELF MAINTENANCE: Introduction
DStop the vehicle on firm level
ground, firmly set the parking brake
and put the transmission in “E(1)”,
“M(1)” or R (multi−mode manual
transmission), or reverse (manual
transmission). Block the wheels di-
agonally opposite to the one being
changed, if necessary.
DMake sure to set the floor jack
properly in the floor jack point.
Raising the vehicle with the floor
jack improperly positioned will dam-
age the vehicle or may allow the
vehicle to fall off the floor jack and
cause personal injury.
DNever get under the vehicle when
the vehicle is supported by the
floor jack alone; use vehicle sup-
port stands.
DDo not raise the vehicle with any-
one in the vehicle.
DWhen raising the vehicle, do not
place any objects on top of or un-
derneath the floor jack.
NOTICE
Be sure to place the floor jack cor-
rectly, or your vehicle may be dam-
aged.
