Your Toyota vehicle has been designed for
fewer maintenance requirements with long-
er service intervals to save both your time
and money. However, each regular mainte-
nance, as well as day- to- day care, is
more important than ever before to ensure
smooth, trouble- free, safe, and economical
drivings.
It is the owner 's responsibility to make
sure the specified maintenance, including
general maintenance service, is performed.
Note that both the new vehicle and emis-
sion control system warranties specify that
proper maintenance and care must be per-
formed. See Owner 's Warranty Informa-
tion Bookletº or Owner 's Manual Supple-
mentº for complete warranty information.
General maintenance
General maintenance items are those day-
to- day care practices that are important to
your vehicle for proper operation. It is the
owner 's responsibility to ensure that the
general maintenance items are performed
regularly.
These checks or inspections can be done
either by yourself or a qualified technician,
or if you prefer, your Toyota dealer will be
pleased to do them at a nominal cost.Scheduled maintenance
The scheduled maintenance items listed in
the Scheduled Maintenance Guideº or
Owner 's Manual Supplementº are those
required to be serviced at regular inter-
vals.
For details of your maintenance schedule,
read the Scheduled Maintenance Guideº
or Owner 's Manual Supplementº.
It is recommended that any replacement
parts used for maintenance or for the
repair of the emission control system
be Toyota supplied.
The owner may elect to use non- Toyota
supplied parts for replacement pur-
poses without invalidating the emission
control system warranty. However, use
of replacement parts which are not of
equivalent quality may impair the effec-
tiveness of the emission control sys-
tems.
You may also elect to have mainte-
nance, replacement, or repair of the
emission control devices and system
performed by any automotive repair es-
tablishment or individual without invali-
dating this warranty. See Owner's War-
ranty Information Bookletº or Owner's
Manual Supplementº for complete war-
ranty information.Where to go for service?
Toyota technicians are well- trained spe-
cialists and are kept up to date with the
latest service information through technical
bulletins, service tips, and in- dealership
training programs. They learn to work on
Toyotas before they work on your vehicle,
rather than while they are working on it.
You can be confident that your Toyota
dealer 's service department performs the
best job to meet the maintenance require-
ments on your vehicleÐreliably and eco-
nomically.
Your copy of the repair order is proof that
all required maintenance has been per-
formed for warranty coverage. If any prob-
lems should arise with your vehicle while
under warranty, your Toyota dealer will
promptly take care of it. Again, be sure
to keep a copy of the repair order for any
service performed on your Toyota.
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 371 in
Section 7.

tant clues are as follows:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)

Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)

Flat- looking tire; excessive tire squeal
when cornering; uneven tire wear

Vehicle pulls to one side when driving
straight on a level road

Strange noises related to suspension

hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.
Does your vehicle need

i
egular maintenance is essential to obtaining the highest level of perfor
mance from your Toyota. It can also increase your vehicle’s resale value.
This booklet presents Toyota’s maintenance recommendations in conve
nient checklists, so you can easily see what type of maintenance your vehicle
needs and document that the work was performed.
To ensure that your vehicle receives firstquality service and parts, Toyota
recommends having maintenance performed by an authorized Toyota dealer
ship. Toyota dealership technicians are experts on Toyota vehicles, and they use
Genuine Toyota Parts designed to your vehicle’s exact specifications. When you
go to a Toyota dealership, you can be confident of the quality that is going on

Maintenance Records
Maintaining your vehicle according to the recommendations in this booklet is
required to ensure that your warranty coverage remains intact. You should keep
detailed records of vehicle maintenance, including date of service, mileage at
time of service and a description of service and/or parts installation performed.
The scheduled maintenance log in this booklet can help you document this
information. If you sell your vehicle, be sure to give your maintenance records to
the new owner.
Toyota will not deny a warranty claim solely because you do not have records
to show that you maintained your vehicle. However, damage or failures caused
by lack of proper maintenance are not covered under warranty.
Maintenance Providers
Maintenance and repair services may be performed by you or by any automotive
service provider you choose. Toyota will not deny a warranty claim solely becauseyou used a service provider other than a Toyota dealership for maintenance and
repairs. However, damage or failures caused by improper maintenance or repairs
are notcovered under warranty.
DealerRecommended Maintenance
Your dealer may recommend more frequent maintenance intervals or more
maintenance services than those listed in the scheduled maintenance log. Theseadditional services are not required to maintain your warranty coverage. Ask your
dealer for an explanation of any recommended maintenance not included in the
scheduled maintenance log.

Miles or Months?
Toyota recommends obtaining scheduled maintenance for your vehicle every
5,000 miles or six months, whichever comes first.
For example:
•If you drive 5,000 miles in less than six months, you should obtain mainte
nance at
5,000 miles— don’t wait until six months.
•If at six months you have driven less than 5,000 miles, you should obtain
maintenance at
six months— don’t wait until 5,000 miles.
Be sure to keep an eye on your mileage so that you obtain maintenance when
recommended. If you are a lowmileage driver, mark your calendar to remind
yourself to obtain maintenance every six months.
Special Operating Conditions
In addition to standard maintenance items, the maintenance log indicates
services that should be performed on vehicles that are driven under especially
demanding conditions. These “special operating conditions” and their required
maintenance items are clearly indicated in each chart.
Note:You should perform these additional maintenance services if you drive
primarilyunder any of the special operating conditions indicated. If you drive
only occasionally under these conditions, it is not necessary to perform the
additional services.
