168Where to go for service?
Toyota technicians are well-trained spe- cialists
and are kept up to date with the lat-
est service information through technical
bulletins, service tips, and in-dealership
training programs. They learn to work on
Toyotas before they work on your vehicle,
rather than while they are working on it.
You can be confident that your Toyota
dealer's service department performs the
best job to meet the maintenance require-
ments on your vehicleÐreliably and eco-
nomically.
Your copy of the repair order is proof that
all required maintenance has been per-
formed for warranty coverage. And if any
problems should arise with your vehicle
while under warranty, your Toyota dealer
will promptly take care of it. Again, be sure
to keep a copy of the repair order for any
service performed on your Toyota.
What about do-it-yourself mainte- nance?
Many of the maintenance items are easy
to do yourself if you have a little mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form them are presented in Part 7. If you are a skilled do-it-yourself me-
chanic, the Toyota service manuals are recommended. Please be aware that do-
it-yourself maintenance can affect your
warranty coverage. See Owner's Guide,
Owner 's
Manual Supplement or W arranty
Booklet for the details. Listed
below are the general maintenance
items that should be performed as fre-quently as specified. In addition to check-
ing the items listed, if you notice any un-
usual noise, smell or vibration, you should
investigate the cause or take your vehicle
to your T oyota dealer or a qualified service
shop immediately. It is recommended
that any problem you notice be brought to
the attention of your dealer or the qualified service shop for their advice.
Make these checks only where
adequate ventilation can be obtain-
ed if you run the engine. CAUTION
!
OUTSIDE THE VEHICLE
Items listed below should be per-
formed from time to time, unless
otherwise specified.
Tire pressure Check the pressure with a gauge every
two weeks, or at least once a month. See Chapter 7-2 for additional information. General maintenance

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 tailgate op- erate smoothly and all latches lock se-
curely. M ake sure the engine hood secon-
dary latch secures the hood from opening

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
Be alert for changes in steering condition, such as hard steering or strange noise. Seats Check that all front seat controls such as
seat adjusters, seatback recliner, etc. op- erate smoothly and that all latches lock
securely in any position. Check that the
head restraints move up and down
smoothly and that the locks hold securely
in any latched position. For folding-down
seatback (bench 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

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 FULLº and LOWº 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 on the dipstick. The level
should be in the HOTº or COLDº range
depending on the fluid temperature. SeeChapter 7-2 for additional information. 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

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 ofthe engine.
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 becorrect.
4. Pull the dipstick out and look at the oil level on the end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.!
If the oil level is below or only slightly
above the low level line, add engine oil
of the same type as already in the en- gine. Remove the oil filter 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 line and the full
level on the dipstick is indicated below forreference. When the level reaches within the correct range, install the filler cap hand-tight.
Oil quantity, L (qt., Imp. qt.):
2RZ-FE and 3RZ-FE engines
1.5 (1.6, 1.3)
5VZ-FE engine Two-wheel drive models 1.5 (1.6,1.3)
Four-wheel drive models 1.2 (1.3,1.1)

182
Avoid overfilling, or the engine
could be damaged.
Check the oil level on the dipstick
once again after adding the oil.
NOTICE
Engine oil selection Use API SH, Energy-Conserving IIº mul- tigrade engine oil or ILSAC multigrade en-
gine oil.
SAE 5W-30 is the best choice for your
vehicle, for good fuel economy and
good starting in cold weather. If you use SAE 10W-30 engine oil in
extremely low temperatures, the en-
gine may become difficult to start, so
SAE 5W-30 engine oil is recom-mended.
API service symbol
ILSAC certification mark

183
Oil identification marks
Either or
both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container. The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SH. The cen-
ter portion of the label shows the SAE vis-
cosity grade such as SAE 5W-30.
Energy-Conserving IIº shown in the low-
er portion, indicates that the oil has fuel-
saving capabilities. Oils marked Ener-
gy-Conserving IIº will have higher
fuel-saving capabilities than oil marked Energy-Conservingº.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee)Certification Mark is displayed on the front
of the container. Look at the see-through coolant res-
ervoir when the engine is cold. The
coolant level is satisfactory if it is be-
tween the Fº and Lº lines on
the res-
ervoir. 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 Lº line, add cool- ant. Bring the level up to the Fº 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.
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
CAUTION! 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 C).
Do not use alcohol type antifreeze
or plain water alone.

Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON [
II or -III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little more
in frigid temperatures), the fluid is hot (40 C ' 80 C or 104 F ' 175 F). You
may also check the level when the fluid is
cold (about room temperature, 0 C '
40 C or 32 F ' 104 F) if the engine has
not been run for about five hours.
a. Clean all dit from outside of the reser- voir tank.
b. Remove the filler cap by turning it
counterclockwise and wipe the dipstick clean. c. Reinstall the filler cap.
d. Remove the filler cap again and look at the fluid level. If the fluid is cold, the level
should be in the COLDº range. Similarly, if it is hot, the fluid level should be in the
HOTº range. If the level is at
the low side
of either range, add automatic transmis-
sion fluid DEXRON -II or III to bring the
level within range.
e. After replacing the filler cap, visually check the steering box case, vane pump
and hose connections for leaks or dam-age.
CAUTION
The reservoir tank may be hot so be careful not to burn yourself.!
Avoid overfilling, or the power steering could be damaged.
NOTICE
Keep your tire pressures at the proper level.
The recommended cold tire pressures, tire size and the cargo weight are also giv-
en in Part 8.
You should check the tire pressures every two weeks, or at least once a month. And
don't forget the spare!
Incorrect tire pressure can reduce tire
life and make your vehicle less safe to drive.
Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts from
overheated tires. Also, low tire pressure
can cause poor sealing of the tread bead.
If the tire pressure is excessively low,
there is the possibility of wheel deforma- tion and/or tire separation.
High tire pressure produces a harsh ride,
handling problems, excessive wear at the center of the tire tread, and a greater pos-
sibility of tire damage from road hazards.
If a tire frequently needs refilling, have it
checked by your Toyota dealer.

Check the battery for corroded or
loose terminal connections, cracks, or
loose hold-down clamp.
a. If the battery is corroded, wash it off with a solution of warm water and baking
soda. Coat the outside of the terminals with grease to prevent further corrosion.
b. If the terminal connections are loose, tighten their clamp nuts±but do not over- tighten.
c. Tighten the hold-down clamp only
enough to keep the battery firmly in place.
Overtightening may damage the battery case.
NOTICE
Be sure the engine and all acces-
sories are off before performing
maintenance.
When checking the battery, re-move the ground cable from the
negative terminal (-º mark) first
and reinstall it last.
Be careful not to cause a short cir-cuit with tools.
Take care no solution gets into thebattery when washing it.
There are two types of batteries: Main-
tenance type and non-maintenance type. A non-maintenance battery has MAIN-
TENANCE FREE BATTERYº on its top. A
maintenance type battery does not havesuch indication. Maintenance type batteryÐ Check the fluid condition by the fluid level
lines on the side of the battery. Or if the
battery has a hydrometer on its top, you
can also check the hydrometer. Non-maintenance batteryÐ
Check the battery condition by the
hydrometer on the top of the battery.
