CAUTION
Before driving off, make sure that the parking brake if fully released
and the parking brake reminder
light is off.
Do not leave your vehicle unat- tended while the engine is run- ning.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill, reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat
and not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking
on a slippery surface. Sudden ac-
celeration or engine braking,
could cause the vehicle to spin or skid.!
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high-speed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss of
control and possible injury. Be sure to consult a tire dealer to de-
termine whether the tires on your
vehicle are high-speed capability tires or not before driving at suchspeeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking
brake will not hold the vehicle se-
curely. Make sure you have ethylene-glycol
antifreeze in the radiator.
Do not use alcohol type antifreeze.
NOTICE
Check the condition of the battery and cables. Cold temperatures reduce the capacity of
any battery, so it must be in top shape to provide enough power for winter starting.Chapter 7-3 tells you how to visually in-
spect the battery. Your Toyota dealer and
most service stations will be pleased tocheck the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Chapter 7-2 for recommended vis-
cosity.
Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealer- he will be pleased to help. Keep the door locks from freezing. Squirt lock de-icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before in- serting it.
Winter driving tips

123
If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a
loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure 0
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) 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 and make sure the electric
cooling fan is operating. If it is not, turn
the ignition off.
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. CAUTION
! 3. Visually check to see if the engine
drive belt (water pump belt) is broken or loose. Look for obvious coolant
leaks from the radiator, hoses, and un-
der the vehicle. However, note that
water draining from the air condition-
ing is normal if it has been used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts. CAUTION
!
4. If the engine drive belt is broken or 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, check the
coolant reservoir. If it is dry, add cool-
ant to the reservoir while the engine is
running. Fill it about half full.
Do not attempt to remove the
radiator cap when the engine and
radiator are hot. Serious injury
could result from scalding hot fluid
and steam blown out underpressure. CAUTION
!
6. After the engine coolant temperature has cooled to normal, again check the
coolant level in the reservoir. If
necessary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at your
Toyota dealer.

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 andtoolsº.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few pr ecautions that you
should be especially careful to observe:
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 flamable.
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
!
Do-it-yourself service precautions

151
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 au- tomatically 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 flying or fal-
ling material, fluid spray, etc.
Used engine oil contains potential-
ly 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 thereach 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.

Remember that battery and igni- tion cable 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 the parts 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.
NOTICE
Use only spark plugs of the speci- fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
Do not overfill automatic trans- mission fluid or the transmissioncould 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 engine
compartment.
Be careful not to scratch the glasssurface with the wiper frame.
When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.

Look at the see-through coolant res-
ervoir when the engine is cold. The
coolant level is satisfactory if it is be-
tween the FULLº and LOWº lines on
the reservoir. If the level is low, add
ethylene-glycol type coolant.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the LOWº line, add
coolant. Bring the level up to the FULLº line. Use only ethylene-glycol type coolant. See information in the next column.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the ra-
diator, hoses, radiator cap and drain cock
and water pump.
If you can find no leak, have your Toyota
dealer
test the cap pressure and check for
leaks in the cooling system.
To prevent burning yourself, do not remove the radiator cap when the
engine is hot.
CAUTION! Coolant type selection
Your coolant must contain ethylene-gly- col antifreeze. In addition to preventingfreezing and subsequent damage to the
engine, this will also prevent corrosion. Further supplemental inhibitors or addi-
tives are neither needed nor recom- mended.
Read
the antifreeze container for informa-
tion on freeze protection. Follow the
manufacturer 's directions for how much
to mix with water. The total capacity of the
cooling system is given in Part 8. We rec-
ommend 50% solution be used for your
Toyota, or a sufficient quantity to provideprotection to about -35 C (-31 F).
Do not use alcohol type antifreeze
or plain water alone.
