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.
7. After the engine coolant temperature
has 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 should have it checked as
soon as possible at your Toyota dealer.
1. Reduce your speed gradually,
keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your
emergency flashers.
3. Firmly set the parking brake and
put the transmission in ªPº.
4. Have everyone get out of the ve-
hicle on the side away from traffic.
5. Read the following instructions
thoroughly.CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury:

Follow jacking instructions.

Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.

Do not start or run the engine
while your vehicle is supported
by the jack.

Stop the vehicle on a level firm
ground, firmly set the parking
brake and put the transmission
in ªPº. Block the wheel diago-
nally opposite to the one being
changed if necessary.

A driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done only
on hard±surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION
Use extreme caution when towing the
vehicle. Avoid sudden starts or errat-
ic driving maneuvers which would
place excessive stress on the emer-
gency towing hook and towing cable
or chain. The hook and towing cable
or chain may break and cause serious
injury or damage.
NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing hook provided.
Before towing, release the parking brake,
put the transmission in ªNº and as to the
four±wheel drive models, moreover, set
the transfer in ª2WDº mode. The key must
be in ªACCº (engine off) or ªONº (engine
running).
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.

Before emergency towing, check that
the hook is not broken or damaged and
that the installation bolts are not loose.

Fasten the towing cable or chain se-
curely to the hook.

Do not jerk the hook. Apply steady and
even force.

To avoid damaging the hook, do not
pull from the side or at a vertical
angle. Always pull straight ahead.

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 hot to the touch.
CAUTION
When cleaning under floor or chassis,
be careful not to injure your hands.
1. Rinse off loose dirt with a hose. Re-
move any mud or road salt from the
underside of the vehicle or in 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 hardÐlet
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 splashes an ornament, be sure to
wash it off with water and check if the
ornament is damaged.
CAUTION
Do not attach the heavily damaged
plastic wheel ornament. It may fly off
the wheel and cause accidents while
the vehicle is moving.

cables carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.

Add only ªToyota Super Long Life
Coolantº or similar high quality eth-
ylene glycol based non±silicate,
non±amine, non±nitrite, and non±bo-
rate coolant with long±life hybrid
organic acid technology to fill the
radiator. ªToyota Super Long Life
