Types of tires
Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break-in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of your
vehicle:

Do not drive over 88 km/h (55 mph).

Run the engine at moderate speed be-
tween 2000 and 4000 rpm.

Avoid full-throttle starts.

Try to avoid hard stops during the first
300 km (200 miles).

Do not drive for a long time at any
single speed, either fast or slow.

Do not tow a trailer during the first 800
km (500 miles). FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups, your
Toyota has a new smaller fuel tank opening.
The special nozzle on pumps with unleaded
fuel will fit it, but the larger standard nozzle
on pumps with leaded gas will not.
Do not use leaded gasoline. Use of
leaded gasoline will cause the
three-way catalytic converter tolose its effectiveness and the emis-
sion control system to function im-
properly. Also, this can increasemaintenance costs.
NOTICE
OCTANE NUMBER
Select Research Octane number 91 (Oc-
tane Rating 87) or higher. For improved
vehicle performance, the use of pre-
mium unleaded gasoline with a Re-
search Octane number of 96 (Ocatne
Rating 91) or higher is recommended.
Use of unleaded fuel with an octane num-
ber or rating lower than stated above will
cause persistant heavy knocking. If se-
vere, this will lead to engine damage.

134The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it
appear that oil is excessively consumed
after driving as high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in proper
vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will
not be impaired. Therefore, it is essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level be
checked every time you refuel the vehicle.
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficientoil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.
Your engine is fitted with twin ground elec-
trode spark plugs.
Use only twin ground electrode
spark plugs for your engine
performance.
NOTICE
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 w ill 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 stopsÐbut no
more!

If your vehicle will not startÐ
(a) Simple checks
151
IN CASE OF AN
EMERGENCY

If your vehicle will not start

If your engine stalls while
driving

If your vehicle overheats

If you have a flat tire

If your vehicle needs to be
towed

If you cannot shift automatic
transmission selector lever

If you lose your keys

If you lose your wireless remote
control transmitter
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in How to start the engineº
in Part 3 and that you have sufficient fuel.
If the engine is not turning over or is
turning over too slowlyÐ
1. Check that the battery terminals are
tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the battery is
discharged. You may try jump starting.
See (c) Jump startingº for further in-
structions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair
shop.
NOTICE
Do not pullÐ or push-start the vehicle. It may damage the vehicle
or cause a collision when the enginestarts. Also the three-way catalyticconverter may overheat andbecome a fire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. Check that all the push-on connectors are tight. (For example, connectors at
the spark plugs, ignition coil and/or dis-
tributor)
2. If the connectors are O.K., the engine may be flooded because of repeated
cranking. See (b) Starting a flooded
engineº for further instructions.

If you perform maintenance by your-
self, be sure to follow the correct pro-
cedure given in this part.
You should be aware that improper or in-
complete servicing may result in operat-
ing problems.
Performing do-it-yourself maintenance
during the warranty period may affect
your warranty coverage. Read the sepa-
rate Toyota Warranty statement for details
and suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Part 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
toolsº.
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:

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, radia-
tor, exhaust manifold, power
steering fluid reservoir and spark
plug boots, etc.Ðwill be hot. So
be careful 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 smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flam-
mable.

Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric
acid.

Do not get under your vehicle with
just the body jack supporting it.
Always use automotive jack
stands or other solid supports. CAUTION

Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling
fans will automatically start to run
if the engine coolant temperature
is high and/or the air conditioning
is on.

Use eye protection whenever you
work on or under you vehicle
where you may be exposed to fly-
ing or falling material, fluid spray,
etc.

Used engine oil contains poten-
tially harmful contaminants which
may cause skin disorders such as
inflammation or skin cancer, so
care should be taken to avoid pro-
longed and repeated contact with
it. To remove 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 deal-
er or a service station for informa-
tion concerning recycling or dis-
posal.

Remember that battery and igni- tion cables carry high currents or
voltages. Be careful of accidental-ly causing a short circuit.
Add only demineralized or dis-tilled w ater to fill the radiator. And
if you spill some of the coolant, be sure to wash it off with water to
prevent it from damaging theparts or paint.
Do not allow dirt or anything elseto fall through the spark plug
holes.
Do not pry the outer electrode of aspark plug against the center elec-
trode.
Use only spark plugs of the speci- fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
NOTICE
Do not reuse platinum-tipped
spark plugs by cleaning or regap-
ping.
Do not overfill automatic trans-mission fluid, or the transmission
could be damaged.
Do not drive with the air cleaner fil-ter removed, or excessive engine
wear could result. Also backfiringcould cause a fire in the enginecompartment.
Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood,check to see that you have not for-gotten any tools, rags, etc.
