NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing eyelet provided.
Before towing, release the parking brake
and put the transmission in N". The en-
gine switch must be in ACC" (engine off)
or ON" (engine running).
Four−wheel drive modelsOn multi−mode
four−wheel drive models, put the multi−
mode control switch knob in H2". On full−
time four−wheel drive models, unlock the
center differential.
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.
Before emergency towing, check that
the eyelet is not broken or damaged
and that the installation bolts are not
loose.
Fasten the towing cable or chain se-
curely to the eyelet.
Do not jerk the eyelet. Apply steady
and even force.
To avoid damaging the eyelet, do not
pull from the side or at a vertical
angle. Always pull straight ahead.
CAUTION
If the emergency towing eyelet is
used to get out when your vehicle
becomes struck in mud, sand or oth-
er condition from which the vehicle
cannot be driven out under its own
power, make sure to observe the pre-
cautions mentioned below. Otherwise,
excessive stress will be put on the
eyelet and the towing cable or chain
may break, causing serious injury or
damage.
If the towing vehicle can hardly
move, do not forcibly continue the
towing. Contact your Toyota dealer
or a commercial tow truck service
for assistance.
Tow the vehicle as straight ahead
as possible.
Keep away from the vehicle during
towing.

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, and trouble−free, safe, and eco-
nomical 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
emission control system warranties specify
that proper maintenance and care must be
performed. See Owner ’s Warranty
Information Booklet" or Owner ’s Manual
Supplement" 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 Guide" or
Owner ’s Manual Supplement" are those
required to be serviced at regular inter-
vals.
For details of your maintenance schedule,
read the Scheduled Maintenance Guide"
or Owner ’s Manual Supplement".
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
maintenance, replacement, or repair of
the emission control devices and
system performed by any automotive
repair establishment or individual
without invalidating this warranty. See
Owner ’s Warranty Information Booklet"
or Owner’s Manual Supplement" for
complete warranty 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 vehiclereliably 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 427 in
Section 7.
Maintenance requirements

423
If you are a skilled do−it−yourself
mechanic, the Toyota service manuals are
recommended. Please be aware that
do−it−yourself maintenance can affect your
warranty coverage. See Owner ’s Warranty
Information Booklet" or Owner ’s Manual
Supplement" for the details.Listed below are the general maintenance
items that should be performed as fre-
quently as specified. In addition to check-
ing the items listed, if you notice any
unusual noise, smell or vibration, you
should investigate the cause or take your
vehicle to your Toyota dealer or a quali-
fied service shop immediately. It is recom-
mended that any problem you notice be
brought to the attention of your dealer or
the qualified service shop for their advice.

damage or excessive wear. See page
443 in Section 7−2 for additional in-
formation. When checking the tires,
make sure no nuts are missing, and
check the nuts for looseness. Tighten
them if necessary.
Tire rotation
Rotate the tires according to the
maintenance schedule. (For
scheduled maintenance information,
please refer to the Scheduled
Maintenance Guide" or Owner ’s
Manual Supplement".) See page 445
in Section 7−2 for additional
information.
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:
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
movement
Loss of brake effectiveness; spongy
feeling brake pedal; pedal almost
touches floor; vehicle pulls to one side
when braking
Engine coolant temperature continually
higher than normal If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.
Does your vehicle need
repairing?

426
Some states have vehicle emission in-
spection programs which include OBD
(On−Board Diagnostics) checks.
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.
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. 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.
If your vehicle does not pass the I/M test
even the malfunction indicator lamp does
not come on, contact your Toyota dealer
to prepare the vehicle for re−testing.

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
tools" on page 432 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:
