Maintenance requirements  
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 daytoday care, is  
more important than ever before to ensure  
smooth, troublefree, safe, and economical  
driving.  
Scheduled maintenance  
Where to go for service?  
The scheduled maintenance items listed in  
the “Scheduled Maintenance Guide” or  
“Owner’s Manual Supplement” are those  
required to be serviced at regular inter-  
vals.  
Toyota technicians are welltrained spe-  
cialists and are kept up to date with the  
latest service information through technical  
bulletins, service tips, and indealership  
training programs. They learn to work on  
Toyotas before they work on your vehicle,  
rather than while they are working on it.  
For details of your maintenance schedule,  
read the “Scheduled Maintenance Guide”  
or “Owner’s Manual Supplement”.  
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  
emission control system warranties specify  
that proper maintenance and care must be  
You can be confident that your Toyota  
dealer’s service department performs the  
best job to meet the maintenance require-  
ments on your vehicle–reliably and eco-  
nomically.  
It is recommended that only genuine  
Toyota parts be used for maintenance  
or for the repair of the emission con-  
trol system.  
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.

“Owner’s

The owner may elect to use non−Toyota  
supplied parts for replacement pur-

control system warranty. However, use

equivalent quality may impair the effec-

General maintenance  
General maintenance items are those day−  
today 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.  
What about do−it−yourself maintenance?  
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 Booklet” or “Owner’s  
Manual Supplement” for complete war-  
ranty information.  
Many of the maintenance items are easy  
to do yourself if you have a little mechani-  
cal ability and

few basic automotive

either by yourself or a qualified technician,  
or if you prefer, your Toyota dealer will be

uneven pedal effort or catching.  
Service reminder indicators and warning  
buzzers  
Check that all service reminder indicators  
and warning buzzers function properly.  
Brake pedal  
Check the pedal for smooth operation and  
that the pedal has the proper clearance.

Does your vehicle need  
repairing?  
Be on the alert for changes in perfor-  
mance, sounds, and visual tipoffs that  
indicate service is needed. Some impor-  
tant clues are as follows:  
If you notice any of these clues, take your  
vehicle to your Toyota dealer as soon as  
possible. It probably needs adjustment or  
repair.  
Tire surface and wheel nuts  
Check the tires carefully for cuts,  
damage or excessive wear. See Sec-  
tion 82 for additional information.  
When checking the tires, make sure  
no nuts are missing, and check the  
nuts for looseness. Tighten them if  
necessary.  
Engine missing, stumbling, or pinging  
Appreciable loss of power  
Strange engine noises  
CAUTION  
Do not continue driving with the ve-  
hicle unchecked. It could result in se-  
rious vehicle damage and possibly  
personal injury.  
A fluid leak under the vehicle (however,  
water dripping from the air conditioning  
after use is normal.)  
Tire rotation  
Rotate the tires according to the  
maintenance schedule. (For sched-  
uled maintenance information, please  
refer to the “Scheduled Maintenance  
Guide” or “Owner’s Manual Supple-  
ment”.) See page 409 for additional  
information.  
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.)  
Flatlooking 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  
movement  
Loss of brake effectiveness; spongy  
feeling brake pedal; pedal almost  
touches floor; vehicle pulls to one side  
when braking  
Coolant temperature continually higher  
than normal  
389  
Emissions inspection and  
maintenance (I/M) programs  
Some states have vehicle emission in-  
spection programs which include OBD  
(OnBoard Diagnostics) checks.  
The malfunction indicator lamp will go off  
after taking several driving trips, but the  
error code in the OBD system will not be  
cleared unless about 40 trips or more are  
taken.  
The OBD system monitors the operation  
of the emission control system. When the  
OBD system determines that a problem  
exists somewhere in the emission control  
system, the malfunction indicator lamp  
comes on. In this case, your vehicle may  
not pass the I/M test and need to be  
repaired. Contact your Toyota dealer to  
service the vehicle.  
If your vehicle does not pass the I/M test  
and the malfunction indicator lamp does  
not come on, contact your Toyota dealer  
to prepare the vehicle for retesting.  
Even if the malfunction indicator lamp  
does not come on, your vehicle may not  
pass the I/M test as readiness codes  
have not been set in the OBD system.  
Readiness codes are automatically set  
during ordinary driving. However, when the  
battery is disconnected or run down, the  
codes are erased. Also, depending on  
your driving habits, the codes may not be  
completely set.  
Also, if the malfunction indicator lamp had  
come on recently due to temporary mal-  
function such as a loose fuel tank cap,  
your vehicle may not pass the I/M test.
