3. Insert your finger into the hole to
move the shift lock override lever
backward. You can shift out of Pº
position only while holding back the
lever.
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.

142Where 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.

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

144IN THE ENGINE COMPARTMENT Items listed below should be checked
from time to time, e.g. each time whenrefueling.
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. See Chapter 7- 2 for
additional information. 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 information.
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. See Chapter 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 driving straight 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

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.
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 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.):
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)

Avoid overfilling, or the engine could be damaged.
Check the oil level on the dipstick
once again after adding the oil.
NOTICE

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 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).
Do not use alcohol type antifreeze
or plain water alone.
NOTICE

Type B
Checking brake fluid
Checking the engine coolant level

158To 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. 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 on the dipstick. If
necessary, add automatic transmis-
sion 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 dirt from outside of the reser- voir tank.
b. Remove the filler cap by turning it
counterclockwise and wipe the dipstick clean.
Checking power steering fluid

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 nutsÐbut 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.

ADDING DISTILLED WATER (MAINTE-
NANCE TYPE BATTERY ONLY)
1. Remove the vent plugs.
2. Add distilled water to cells needing fluid.
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 theground cable.
3. Be sure the power switch on the re-
charger is off when connecting the char-ger cables to the battery and when dis-
connecting 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
!
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.
