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.
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 (fan belt) is broken or loose.
Look for obvious coolant leaks from
the radiator, hoses, and under the ve-
hicle. However, note that water drain-ing from the air conditioning 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 of the 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, you may
help the engine cool down more quick-
ly by running it at about 1500 rpm for
a few minutes with the accelerator
pedal lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant 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
!
7. 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 your vehicle overheats

1381. Reduce
your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from the
traf fic. Avoid stopping on the center di-
vider of a highway. Park on a level spotwith firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in Pº (automatic) or reverse (manual).
4. Have everyone get out of the vehicle on the side away from traffic.
5. Read the following instructions thor- oughly.
When jacking, be sure to observe
the following to reduce the
possibility of personal injury: Follow jacking instructions.

6. After making sure that no one is inthe vehicle, raise it high enough so
that the spare tire can be installed.
Remember you will need more ground
clearance when putting in the spare tirethan when removing the flat tire.
To raise the vehicle, insert the jack handle
into the jack (it is a loose fit) and turn it
clockwise. As the j ack touches the vehicle
and begins to lift, double-check that it is
properly positioned.
Never get under the vehicle when it is supported by the jack alone. CAUTION
!
7. Remove the wheel nuts and change
tires.
Lift the flat tire straight off and put it aside.
Roll the spare wheel into position and
align the holes in the wheel with the bolts.
Then lift up the wheel and get at least thetop bolt started through its hole. Wigglethe tire and press it back over the other bolts.Before putting on wheels, remove any
corrosion on the mounting surfaces with a
wire brush or such. Installation of wheels
without good metal-to-metal contact at
the mounting surface can cause wheel
nuts to loosen and eventually cause a
wheel to come off while driving. Therefore
after the first 1600 km (1000 miles), check
to see that the wheel nuts are tight.
