TANDEM MASTER CYLINDER BRAKE
SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fail, the other will still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
Also, the brake system warning light may
come on.
CAUTION!
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stops - but no
more!
CAUTION!

Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re-
serve.

Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push
the pedal hardÐmuch harder
than normal. And your braking
distance will be longer.
ANTI-LOCK BRAKE SYSTEM
(with ABSº warning light)
The anti- lock brake system is designed to
automatically help prevent lock- up of the
wheels during sudden braking or braking on
slippery road surfaces. This assists in pro-
viding directional stability and steering per -
formance of the vehicle under these cir -
cumstances.
The anti- lock brake system becomes op-
erative after the vehicle has accelerated to
a speed in excess of approximately 10 km/h
(6 mph). It stops operating when the vehicle
decelerates to a speed below approximate-
ly 5 km/h (3 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.Effective way to press the ABSº brake
pedal: When the anti-lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti-lock brake
system work for you, just hold the brake
pedal down more firmly. Do not pump
the brake. This will result in reduced
braking performance.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz-
ardous road surface conditions. Although
the anti-lock brake system assists in pro-
viding vehicle control, it is still important to
drive with all due care, because the anti-
lock brake system cannot overcome the
laws of physics that act on your vehicle:

Braking capab ility is dependent on tire
friction with the road surface.

Even though the anti-lock brake sys-
tem is operating, a driver cannot main-
tain full control on certain slippery road
surfaces, when cornering at high
speeds, or in violent maneuvers.

Avoid high speeds on wet roads. The
anti-lock brake system cannot elimi-
nate the risk of hydroplaning and loss
of tire friction.

Avoid continuous speeding up and
slowing down. Stop-and-go driving
wastes fuel.

Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or take
advantage of through streets to avoid
traffic lights. Keep a proper distance
from other vehicles to avoid sudden
braking. This will also reduce wear on
your brakes.

Avoid heavy traffic or traffic jams
whenever possible.

Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econ-
omy.

Maintain a moderate speed on
highways. The faster you drive, the
greater the fuel consumption. By re-
ducing your speed, you will cut down
on fuel consumption.

Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on the
engine, which, in turn, wastes fuel.

Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps prevent
corrosion.

Keep your vehicle tuned-up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For lon-
ger life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your ve-
hicle receives more frequent mainte-
nance (For scheduled maintenance in-
formation, please refer to the separate
Owner 's Manual Supplement/Main-
tenance Scheduleº).
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is
running.!

Wash the underside of the vehicle
thoroughly when winter is over.
See Washing and waxing your Toyotaº
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
bodyshop make the repair.
Check the interior of your vehicle. Wa-
ter and dirt can accumulate under the floor
mats and could cause corrosion. Occa-
sionally check under the mats to make
sure the area is dry. Be particularly careful
when transporting chemicals, cleansers,
fertilizers, salt, etc; these should be trans-
ported in proper containers. If a spill or
leak should occur, immediately clean and
dry the area.
Use mud shields on your wheels. If you
drive on salted or gravel roads, mud
shields help protect your vehicle. Full-
size shields, which come as near to the
ground as possible, are the best. We rec-
ommend that the fittings and the area
where the shields are installed be treated
to resist corrosion. Your Toyota dealer will
be happy to assist in supplying and instal-
ling the shields if they are recommended
for your area. Do not park your vehicle in a damp,
poorly ventilated garage.
If you wash
your vehicle in the garage, or if you drive
it in covered with water or snow, your ga-
rage may be so damp it will cause corro-
sion. Even if your garage is heated, a wet
vehicle can corrode if the ventilation is
poor. Washing your Toyota by hand
Work in the shade and wait until the ve-
hicle body is not hot to the touch.
CAUTION
When cleaning under floor or chas-
sis, be careful not to injure your
hands.!
Convertible models-For washing instruc-
tions for the convertible top, see Convert-
ible topº.
1. Rinse off loose dirt with a hose. Re-
move any mud or road salt from the un-
derside of the vehicle or in the wheel
wells.

Convertible models: Spray water on the
side windows or top seals from above, at
a 455 angle to the ground.
NOTICE
(convertible models): Do not spray water at side windowsand top seals in a way which maycause water to enter the vehicle.
2. Wash with a mild car-wash soap,
mixed according to the manufacturer's in-
structions. Use a soft cotton mitt and keep
it wet by dipping it frequently into the wash
water. Do not rub hard-let the soap and
water remove the dirt. Aluminum
wheels: Use only a mild soap or
neutral detergent.
Plastic bumpers: Wash carefully. Do not
scrub w ith 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 gasoline or strong solvents, which may be toxic or
cause damage.
3. Rinse thoroughly Ð dried 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 ve-
hicle using a clean soft cotton towel. Do
not rub or press hard Ð you might scratch
the paint.
Automatic car wash
Coupe and liftback models may be
washed in an automatic car wash, but re-
member that the paint can be scratched
by some type of brushes, unfiltered wash-
ing 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 whether the process is safe
for the paint on your vehicle.
NOTICE
(convertible models): Do not run convertible modelsthrough automatic car washer orpossible damage to the convertible
top may result.
Waxing your Toyota
Polishing and waxing is recommend-
ed to maintain the original beauty of
your Toyota's finish.
1. Always wash and dry the vehicle be-
fore you begin waxing, even if you are us-
ing 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, followed
by a separate wax. Carefully follow the
manufacturer 's instructions and precau-
tions. 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 surface
in large patches.
NOTICE
Always remove the plastic bumpers if your vehicle is re-painted and
placed in a high heat paint waxingbooth. High temperatures could
damage the bumpers.
