CAUTION

If the total trailer weight exceeds
453 kg (1000 lb.), trailer brakes are
required.

Never tap into your vehicle's hy-
draulic system as it would lower its
braking effectiveness.

Never tow a trailer without using a
safety chain securely attached to
both the trailer and the vehicle. If
damage occurs to the coupling unit
or hitch ball, there is danger of the
trailer wandering over into another
lane.
SERVICE CONNECTOR FOR TOWING
BRAKE CONTROLLER (with towing
package)
Your vehicle is equipped with a service
connector for the towing brake controller
as shown. Link the connector to the tow-
ing brake controller via the sub wire har-
ness stored in the glove box. The detailed
explanation of the sub wire harness circuit
is packed together with the sub wire har-
ness.
Be sure to position the towing brake con-
troller where it does not prevent the driver
from operating the pedal.
Toyota recommends that the sub wire har-
ness be stored in the glove box when it
is not in use.TIRES

Ensure that your vehicle's tires are
properly inflated. See page 429 in Sec-
tion 7±2 and page 458 in Section 8 for
instructions.

The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.

TRAILER TOWING TIPS
When towing a trailer, your vehicle will
handle differently than when not tow-
ing. The three main causes of vehicle±
trailer accidents are driver error, exces-
sive speed and improper trailer loading.
Keep these in mind when towing:

Before starting out, check operation of
the lights and all vehicle±trailer connec-
tions. After driving a short distance,
stop and recheck the lights and con-
nections. Before actually towing a trail-
er, practice turning, stopping and back-
ing with a trailer in an area away from
traffic until you learn the feel.

Backing with a trailer is difficult and
requires practice. Grip the bottom of
the steering wheel and move your hand
to the left to move the trailer to the
left. Move your hand to the right to
move the trailer to the right. (This pro-
cedure is generally opposite to that
when backing without a trailer.) Also,
just turn the steering wheel a little at
a time, avoiding sharp or prolonged
turning. Have someone guide you when
backing to reduce the risk of an acci-
dent.

Because stopping distance may be in-
creased, vehicle±to±vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of
speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as
you may skid, resulting in jackknifing
and loss of control. This is especially
true on wet or slippery surfaces.

Avoid jerky starts or sudden accelera-
tion.

Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.

Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this by
making a larger than normal turning
radius with your vehicle.

Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. Steer
straight ahead. If you make no extreme
correction with the steering or brakes,
the vehicle and trailer will stabilize.

Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room befo-
re changing lanes.

In order to maintain engine braking effi-
ciency, do not use overdrive.

If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to ªACCº or
ªLOCKº position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve-
hicle and turn on your emergency
flashers. Put the transmission in ªPº
and apply the parking brake. Turn off
the air conditioning if it is being used.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Visually check to see if the engine
drive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or the
coolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as-
sistance.
5. If the engine drive belt is O.K. and
there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry,
add coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type, see ªCoolant type
selectionº on page 427 in Section 7±2.

Toyota, through the diligent research, de-
sign and use of the most advanced
technology available, helps prevent corro-
sion and provides you with the finest qual-
ity vehicle construction. Now, it is up to
you. Proper care of your Toyota can help
ensure long±term corrosion prevention.
The most common causes of corrosion
to your vehicle are:

The accumulation of road salt, dirt and
moisture in hard±to±reach areas under
the vehicle.

Chipping of paint, or undercoating
caused by minor accidents or by
stones and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmental condi-
tions:

Road salt or dust control chemicals will
accelerate corrosion, as will the pres-
ence of salt in the air near the sea±
coast or in areas of industrial pollution.

High humidity accelerates corrosion es-
pecially when temperatures range just
above the freezing point.

Wetness or dampness to certain parts
of your vehicle for an extended period
of time, may cause corrosion even
though other parts of the vehicle may
be dry.

High ambient temperatures can cause
corrosion to those components of the
vehicle which do not dry quickly due to
lack of proper ventilation.
The above signifies the necessity to keep
your vehicle, particularly the underside, as
clean as possible and to repair any dam-
age to paint or protective coatings as
soon as possible.
To help prevent corrosion on your
Toyota, follow these guidelines:
Wash your vehicle frequently. It is, of
course, necessary to keep your vehicle
clean by regular washing, but to prevent
corrosion, the following points should be
observed:

If you drive on salted roads in the
winter or if you live near the ocean,
you should hose off the undercarriage
at least once a month to minimize cor-
rosion.

High pressure water or steam is effec-
tive for cleaning the vehicle's underside
and wheel housings. Pay particular
attention to these areas as it is difficult
to see all the mud and dirt. It will do
more harm than good to simply wet the
mud and debris without removing. The
lower edge of doors, rocker panels and
frame members have drain holes which
should not be allowed to clog with dirt
as trapped water in these areas can
cause corrosion.

Wash the underside of the vehicle thor-
oughly when winter is over.
See ªWashing and waxing your Toyotaº on
page 405 in this Section for more tips.
Check the condition of your vehicle's
paint and trim. If you find any chips or
scratches in the paint, touch them up im-
mediately to prevent corrosion from start-
ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair.

Aluminum wheels: Use only a mild soap
or neutral detergent.
Plastic bumpers: Wash carefully. Do not
scrub with abrasive cleaners. The bumper
faces are soft.
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 thoroughlyÐdried soap can
cause 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 hardÐyou 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 car±cleaning 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 re±painted and placed
in a high heat paint waxing booth.
High temperatures could damage the
bumpers.

When cleaning the inside of the
rear quarter window, be careful not
to scratch or damage the printed
antenna.
Air conditioning control panel, audio
panel, instrument panel, console panel,
and switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly wipe off dirt.
NOTICE

Do not use organic substances (sol-
vents, kerosene, alcohol, gasoline,
etc.) or alkaline or acidic solutions.
These chemicals can cause discol-
oring, staining or peeling of the
surface.

If you use cleaners or polishing
agents, make sure their ingredients
do not include the substances men-
tioned above.

If you use a liquid car freshener, do
not apill the liquid onto the ve-
hicle's interior surfaces. It may con-
tain the ingredients mentioned
above. Immediately clean any spill
using the method mentioned above.
Leather Interior
The leather upholstery may be cleaned
with neutral detergent for wool.
Remove dirt using a soft cloth dampened
with 5% solution of neutral detergent for
wool. Then thoroughly wipe off all traces
of detergent with a clean damp cloth.After cleaning or whenever any part of the
leather gets wet, dry with a soft clean
cloth. Allow the leather to dry in a venti-
lated shaded area.
NOTICE

If a stain should fail to come out
with a neutral detergent, apply a
cleaner that does not contain an
organic solvent.

Never use organic substances such
as benzine, alcohol or gasoline, or
alkaline or acid solutions for clean-
ing the leather as these could
cause discoloring.

Use of a nylon brush or synthetic
fiber cloth, etc. may scratch the
fine grained surface of the leather.

Mildew may develop on soiled leath-
er upholstery. Be especially careful
to avoid oil spots. Try to keep your
upholstery always clean.

Long exposure to direct sunlight
may cause the leather surface to
harden and shrink. Keep your ve-
hicle in a shaded area, especially in
the summer.

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 emis-
sion control system warranties specify that
proper maintenance and care must be per-
formed. See ªOwner 's Warranty Informa-
tion Bookletº or ªOwner '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 ªScheduled Maintenance Guideº or
ªOwner 's Manual Supplementº are those
required to be serviced at regular inter-
vals.
For details of your maintenance schedule,
read the ªScheduled Maintenance Guideº
or ªOwner '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 ªOwner's War-
ranty Information Bookletº or ªOwner'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 417 in
Section 7.

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 ªParts and
toolsº on page 421 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
compartmentÐthe engine, radiator,
exhaust manifold, power steering
fluid reservoir and spark plug
boots, etc.Ðwill 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.

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.
