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.
Parts and tools
Here is a list of parts and tools you will
need on performing do-it-yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
Checking the engine oil level
Parts (if level is low):
Engine oil API grade SH, ”Energy-Con-
serving II” or SJ, “Energy −Conserving”
multigrade or ILSAC multigrade having
viscosity proper for your climate
Tools: Rag or paper towel
Funnel (only for adding oil)
Checking the engine coolant level
Parts (if level is low): Ethylene-glycol antifreeze
Demineralized or distilled water
Tools: Funnel (only for adding coolant)
Checking brake fluid
Parts (if level is low): SAE J1703 or FMVSS No.116 DOT 3
brake fluid Tools:
Rag or paper towel
Funnel (only for adding fluid)
Checking power steering fluid
Parts (if level is low): Automatic transmission fluid DEXRON
II or III
Tools: Rag or paper towel
Funnel (only for adding fluid)
Checking battery condition
Tools:
Warm water
Baking soda
Grease
Conventional wrench (for terminal
clamp bolts)
Checking and replacing fuses
Parts (if replacement is necessary): Fuse with same amperage rating as
original

Checking the engine oil level
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 ex-
haust 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 ref-
erence.
When the level reaches within the correct
range, install the filler cap hand-tight.

Checking brake fluid
To check the fluid levels, simply look at
the see-through reservoirs. The level
should be between the ”MAX” and
”MIN” 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
level 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.
NOTICE
If you spill the fluid, be sure to wash
it off with water to prevent it from
damaging the parts or paint.
Checking power steering fluid
Check the fluid level on the dipstick. If
necessary, add automatic transmission
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.

T100(U)183
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 ”COLD”
range on the dipstick. Similarly, if it is
hot, the fluid level should be in the
”HOT” range. If the level is at the low
side of either range, add automatic
transmission fluid DEXRON
-II or -III
to bring the level within the range.
e. 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.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.
Checking tire pressure
Keep your tire pressures at the proper
level.
The recommended cold tire pressures, tire
size and the cargo weight rating are given
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 tire 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
possibility of tire damage from road haz-
ards.
If a tire frequently needs refilling, have it
checked by your Toyota dealer. The following instructions for checking
tire pressure should be observed:
The pressure should be checked only
when the tires are cold. If your ve-
hicle has been parked for at least 3
hours and has not been driven for
more than 1.5 km or 1 mile since, you
will get an accurate cold tire pressure
reading.
Always use a tire pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire pressures that
are even just a few pounds off can
degrade handling and ride.
Do not bleed or reduce tire pressure
after driving. It is normal for the tire
pressure to be higher after driving.
Never exceed the cargo weight rat-
ing. The luggage weight should be dis-
tributed evenly.
Be sure to reinstall the tire inflation
valve caps. Without the valve caps,
dirt or moisture could get into the valve
core and cause air leakage. If the caps
have been lost, have new ones put on
as soon as possible.
