3. Insert the screwdriver or equivalent
into the hole to pull down the shift
lock override button. You can shift
out of Pº position only while push-
ing the button.
4. Shift into Nº position.
5. Insert the cover.
6. Start the engine. For your safety, keep the brake pedal depressed.
Be sure to have the system checked by
your Toyota dealer as soon as possible. Many Toyota dealers can make a new
key if you can give them the key num-
ber.
See the suggestion given in Keysº in
Chapter 1-2.
If your keys are locked in the vehicle and
you cannot get a duplicate, many Toyota
dealers
can still open the door for you, us-
ing their special tools. If you must break a
window to get in, we suggest breaking the
smallest side window because it is the
least expensive to replace. Be extremely
cautious to avoid cuts from the glass. If you lose your transmitter, you can
purchase a new one at your Toyota
dealer.
You can use the wireless remote control
system with the new transmitter. Contact
your Toyota dealer for detailed informa-
tion.

176Where 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 ob-
tained if you run the engine. CAUTION
!
OUTSIDE THE VEHICLE
Items listed below should be per-
formed from time to time, unless
otherwise specified.

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.ProCarManuals.com

178Engine 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 driving
straight on a level road

Strange noises related to suspension
movement

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
If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
Do not continue driving with the
vehicle unchecked. It could result
in serious vehicle damage and
possibly personal injury. CAUTION

Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling
fans will automatically start to run
if the engine coolant temperature
is high and/or the air conditioning
is on.

Use eye protection whenever you
work on or under you vehicle
where you may be exposed to fly-
ing or falling material, fluid spray,
etc.

Used engine oil contains poten-
tially harmful contaminants which
may cause skin disorders such as
inflammation or skin cancer, so
care should be taken to avoid pro-
longed and repeated contact with
it. To remove used engine oil from
your skin, wash thoroughly with
soap and water.

Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers
or onto the ground. Call your deal-
er or a service station for informa-
tion concerning recycling or dis-
posal.

Remember that battery and igni- tion cables carry high currents or
voltages. Be careful of accidental-ly causing a short circuit.
Add only demineralized or dis-tilled w ater to fill the radiator. And
if you spill some of the coolant, be sure to wash it off with water to
prevent it from damaging theparts or paint.
Do not allow dirt or anything elseto fall through the spark plug
holes.
Do not pry the outer electrode of aspark plug against the center elec-
trode.
Use only spark plugs of the speci- fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
NOTICE
Do not reuse platinum-tipped
spark plugs by cleaning or regap-
ping.
Do not overfill automatic trans-mission fluid, or the transmission
could be damaged.
Do not drive with the air cleaner fil-ter removed, or excessive engine
wear could result. Also backfiringcould cause a fire in the enginecompartment.
Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood,check to see that you have not for-gotten any tools, rags, etc.

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 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 be
correct.
4. Pull the dipstick out and look at the oil level on the end.
CAUTION
Be careful not to touch the hot
exhaust manifold.!
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.): 1.5 (1.6, 1.3)

Avoid overfilling, or the engine could 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.
To prevent burning yourself, do not
remove the radiator cap when the
engine is hot.
CAUTION!
Coolant type selection
Your coolant must contain ethylene-gly-
col antifreeze. In addition to preventing
freezing 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 provide
protection to about -35 C (-31 C).
Do not use alcohol type antifreeze
or plain water alone.
NOTICE
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.

188If the level is low, add SAE J1703 or
FMVSS No. 116 DOT 3 brake fluid to the
brake reservoir.
Remove and replace the reservoir cover
by hand. Fill the brake fluid to the dotted
line.
This brings the fluid to the correct lev-
el when you put the cover back on.
Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture
from the air, and excess moisture can
cause a dangerous loss of braking.
CAUTION
Take care when filling the reservoir
because brake fluid can harm your
eyes and damage painted surfaces. If
fluid gets in your eyes, flush your
eyes with clean water.!
If you spill the fluid, be sure to wash it off with water to prevent it from
damaging the parts or paint.
NOTICE
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
(60 C ' 80 C or 140 F ' 175 F). You
may also check the level when the fluid is
cold (about room temperature, 10 C '
30 C or 50 F ' 85 F) if the engine has
not been run for about five hours. Clean all dirt from outside of the reservoir
tank 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 auto-
matic transmission fluid DEXRON
[-II or
-III to bring the level within range.
To remove the filler cap, turn it counter-
clockwise and lift up. To reinstall it, turn it
clockwise. After replacing the filler cap,
visually check the steering box case, vane
pump and hose connections for leaks or
damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.!
Avoid overfilling, or the power steering could be damaged.

Check the battery for corroded or
loose terminal connections, cracks, or
loose hold-down clamp.
a. If the battery is corroded, wash it offwith a solution of warm water and bak-
ing soda. Coat the outside of the termi-
nals with grease to prevent further cor-
rosion.
b. If the terminal connections are loose, tighten their clamp nuts±but do not
overtighten.
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) firstand 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 have
such 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.
