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 “P”
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.
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. Look for obvious coolant leaks from theradiator, 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 coolant is leaking, stop the en-gine immediately. Call a Toyota dealer
for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
CAUTION
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 under pressure.
6. After the engine coolant temperaturehas cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Toyota dealer.

Check the interior of your vehicle. Wa-
ter and dirt can accumulate under the
floor mats and could cause corrosion. Oc-
casionally check under the mats to make
sure the area is dry. Be particularly care-
ful when transporting chemicals, cleans-
ers, fertilizers, salt, etc.; these should be
transported 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 recommend
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 installing
the shields if they are recommended for
your area.
Keep your vehicle in a well ventilated
garage or a roofed place. Do not park
your vehicle in a damp, poorly venti-
lated garage. If you wash your vehicle in
the garage, or if you drive it covered with
water or snow, your garage may be so
damp as to cause corrosion. Even if your
garage is heated, a wet vehicle can cor-
rode if the ventilation is poor. Washing your Toyota
Keep your vehicle clean by regular
washing.
The following cases may cause weakness
to the paint or corrosion to the body and
parts. Wash your vehicle as soon as pos-
sible.
When driving in a coastal area
When driving on a road sprinkled with
antifreeze
When exposed to coal tar, tree sap,
bird droppings and carcass of an insect
When driving in areas where there is
a lot of smoke, soot, dust, iron dust or
chemical substances
When the vehicle becomes remarkably
dirty with dust and mud
Hand washing your Toyota
Work in the shade and wait until the
vehicle body is not warm to the touch.
CAUTION
When cleaning under floor or chas-
sis, be careful not to injure your
hands.
Exhaust gases cause the exhaust
pipe to become quite hot. When
washing the vehicle, be careful not
to touch the pipe until it has cooled
sufficiently, as touching a hot ex-
haust pipe can cause burns.
1. Rinse off loose dirt with a hose. Re- move any mud or road salt from the
underside of the vehicle or the wheel
wells.
2. Wash with a mild car −wash soap,
mixed according to the manufacturer ’s
instructions. 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.
Fuel filler door: Do not apply water (high −
pressure car wash, for example) at or
near the fuel tank inlet with the fuel filler
door opened. If the water enters the air
vent, you may experience trouble with re-
fueling or rough engine idling.
Plastic wheel ornaments: The plastic
wheel ornaments are damaged easily by
organic substances. If any organic sub-
stances splash an ornament, be sure to
wash them off with water and check if the
ornament is damaged.
