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 vehicle
and turn on your emergency flashers. Put
the transmission in Pº (automatic) or neu-
tral ( manual) and apply the parking brake.
Turn off the air conditioning if it is beingused.
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 vehicle. However, note that water draining from the air condi-
tioning 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 the
coolant is leaking, stop the engine imme-
diately. Call a Toyota dealer for assis-tance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may help
the engine cool down more quickly by run- ning it at about 1500 rpm for a few minutes with the accelerator pedal lightly de-pressed.
6. Check the coolant reservoir. If it is dry,
add coolant to the reservoir while the en-gine is running. Fill it about half full.
Do not attempt to remove the radia-
tor cap when the engine and radia-
tor are hot. Serious injury could re-
sult from scalding hot fluid and
steam blown out under pressure. 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 cool- ant loss indicates a leak in the system.
You should have it checked as soon as
possible at your Toyota dealer.

Tire surface and wheel nuts Check the tires carefully
for cuts, damage
or excessive wear. See Chapter 7-2 for
additional information. When checking the tires, make sure no nuts are missing,
and check the nuts for looseness. T ighten
them if necessary.
Tire rotation
Rotate the tires every 12000 km (7500
miles). See Chapter 7-2 for additional in-formation.
Fluid leaks Check underneath for leaking fuel, oil, wa-
ter or other fluid after the vehicle has been
parked for a while. If you smell fuel fumes
or notice any leak, have the cause found
and corrected immediately. Doors and engine hood
Check that all doors including back door
operate smoothly and all latches lock se-
curely. M ake sure the engine hood secon-
dary latch secures the hood from opening
when the primary latch is released. INSIDE THE VEHICLE Items listed below should be checked
regularly, e.g. while performing peri-
odic services, cleaning the vehicle,etc. Lights Make sure the headlights, stop lights, tail lights, turn signal lights, and other lights are all working. Check headlight aim. Service reminder indicators and
warn-
ing buzzers Check that all service reminder indicators
and warning buzzers function properly. Steering wheel
Check that it has the specified freeplay.
Be alert for changes in steering condition,such as hard steering or strange noise. Seats Check that all seat controls such as seat
adjusters, seatback recliner, etc. operate
smoothly and that all latches lock securely
in any position. Check that the head re-
straints move up and down smoothly and
that the locks hold securely in any latched
position. For folding-down rear seat-
backs, swing-up rear seat cushions and
detachable temporary third seat, check
that the latches lock securely. Seat belts
Check that the seat belt system such as
buckles, retractors and anchors operate
properly
and smoothly. Make sure the belt
webbing is not cut, frayed, worn or dam-aged. Accelerator pedal Check the pedal for smooth operation and
uneven pedal effort or catching. Clutch pedal Check the pedal for smooth operation. Brake pedal Check the pedal for smooth operation and
that the pedal has the proper clearance. Check the brake booster function. Brakes
At a safe place, check that the brakes do not pull to one side when applied. Parking brake Check that the lever has the proper travel and that, on a safe incline, your vehicle is
held securely with only the parking brake applied.

Aluminum wheel precautions
With the engine at operating tempera- ture and turned off, check the oil level
on the dipstick.
1. To get a true reading, the vehicle
should be on a
level spot. After turning off
the engine, wait a few minutes for the oil
to drain back into the bottom of the en-gine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick 'push it in as far
as it will go, or the reading will not be cor- rect.
4. Pull the dipstick out and look at the oil level on the end. If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine. Remove the oil filler cap and add engine
oil in small quantities at a time, checking the dipstick.
The approximate quantity of oil needed to fill between the low level and the full level
on the dipstick is indicated below for refer- ence.
When the level reaches within the correct range, install the filler cap hand-tight.
Oil quantity, L (qt., Imp. qt.):
3RZ-FE engine1.5 (1.6, 1.3)
5VZ-FE engine 1.2 (1.3, 1.1)
NOTICE
Avoid overfilling, or the enginecould be damaged.
Check the oil level on the dipstick
once again after adding the oil.

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.
CAUTION!
To prevent burning yourself, do not
remove the radiator cap when the
engine is hot. 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).
NOTICE
Do not use alcohol type antifreeze or plain water alone.
To check the fluid level, simply look at
the see-through reservoir. The level
should be between the MAXº and
MINº lines on the reservoir. It is normal for the brake fluid level to go
down slightly as the brake pads wear. So be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it may indicate a serious mechanical prob- lem.
If the level is low, add SAE J1703 or
FMVSS No. 116 DOT 3 brake fluid to the
brake reservoir.
