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 and back door oper-
ate smoothly and all latches lock securely. Make sure the engine hood secondary 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. For folding-up rear
seat-backs, 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.

158Automatic transmission Parkº
mech-
anism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your ve-
hicle is held securely with the selector lever in ºPº position and all brakes re- leased.
IN THE ENGINE COMPARTMENT Items listed below should be checked
from time to time , e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7-3 for additional infor-
mation.
Engine coolant level Make sure the coolant level is between
the ºFULLº and ºLOWº lines on the see-
through reservoir when the engine is cold.
See Chapter 7-2 for additional informa-tion.
Battery electrolyte level Make sure the electrolyte level of all bat-
tery cells is between upper and lower level
lines on the case. Add only distilled water
when replenishing. See Chapter 7-3 for
additional information. Brake fluid level
Make sure the brake fluid level is correct. See Chapter 7-2 for additional informa-tion.
Engine oil level
Check the l
evel on the dipstick with the en-
gine turned off and the vehicle parked on
a level spot. See Chapter 7-2 for addition-
al information. Power steering fluid level Check the level through the reservoir. The
level should be in the HOTº or COLDº
range depending on the fluid t emperature.
See Chapter 7-2 for additional informa- tion.
Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.) Be on the alert for changes in perfor-
mance, sounds, and visual tip-offs
that in-
dicate service is needed. Some important
clues are as follows: Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when drivingstraight on a level road
Strange noises related to suspensionmovement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continual-
ly higher than normal
Does your vehicle need repairing?

ADDING DISTILLED WATER (MAINTE-
NANCE TYPE BATTERY ONLY)
1. Remove the vent plugs.
2. Add distilled water to cells needingfluid.
If the side of your battery is covered,
check the water level by looking down di-
rectly above the cell as illustrated above.
3. Retighten the vent plugs securely.
NOTICE
Do not overfill the cells. Excess electrolyte could squirt out of the
battery during heavy charging,causing corrosion or damage.During recharging, the battery is pro-
ducing hydrogen gas. Therefore, before recharging:
1. Maintenance type batteriesÐRemove the vent plugs.
2. If recharging with the battery installed on the vehicle, be sure to disconnect the ground cable.
3. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and
when disconnecting them.
Always charge the battery in an
unconfined area. Do not charge
the battery in a garage or closed
room where there is not sufficient ventilation.
Non-maintenance batteries: Only
do a slow charge (5A or less).
Charging at a quicker rate is dan-
gerous. The battery may explode,
causing personal injuries.
Maintenance type batteries: Be sure to remove the vent plugs be-fore recharging. CAUTION
!
Battery recharging precautions

184Type A fuses can be pulled out by using the pull-out tool. The location of the pull- out tool is shown in the illustration.
If you are not sure whether the fuse has
blown, try replacing the suspected fuse with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an emergency you can pull out the CIG &
RADº, DOMEº or A/Cº fuse, which may
be dispensable for normal driving, and use it if its amperage rating is the same.
If you cannot use one of the same amper-
age, use one that is lower, but as close as
possible to the rating. If the amperage is
lower than that specified, the fuse might
blow out again but this does not indicate
anything
wrong. Be sure to get the correct
fuse as soon as possible and return the
substitute to its original clip.
It is a good idea to purchase a set of spare
fuses and keep them in your vehicle for emergencies. If the new fuse immediately blows out,there is a problem with the electrical sys-
tem. Have your Toyota dealer correct it as
soon as possible.
Never use a fuse with a higher
amperage rating, or any other
object, in place of a fuse. This maycause extensive damage and
possibly a fire.
CAUTION
!
Check
the washer fluid level in the res-
ervoir with the dipstick. If the washer
fluid level is low, reinsert the dipsticksecurely and add washer fluid through
the opening for added fluid.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below freezing point, use
washer fluid containing antifreeze. This
product is available at your Toyota dealer
and most auto parts stores. Follow the
manufacturer 's directions for how much
to mix with water. Adding washer fluid
