With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick. 1. To get a correct reading, the vehicle should be on level ground. After turning
off the engine, wait a few minutes for
the oil to drain back into the bottom of
the engine.
2. Pull the dipstick out, hold a rag under the end and wipe it clean.
3. Reinsert the dipstickpush 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 while holding a rag under the
end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
NOTICE
Be careful not to drop engine oil on
the vehicle components.
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. We recommend that you use
a funnel when adding oil.
The approximate quantity of oil needed to
raise the level between low and full on the
dipstick is indicated as follows:1.5L(1.6qt.,1.3Imp.qt.)
For the engine oil capacity, see Service
specifications" on page 463 in Section 8.
When the level reaches within the correct
range, install the f iller cap hand−tight.
NOTICE
Be careful not to spill engine oil on
the vehicle components.
 Avoid overfilling, or the engine
could be damaged.
 Check the oil level on the dipstick
once again after adding the oil.

To ensure excellent lubrication perfor-
mance for your engine, Toyota Genuine
Motor Oil" is available, which has been
specifically tested and approved for all
Toyota engines.
Please contact your Toyota dealer for fur-
ther details about Toyota Genuine Motor
Oil".Look at the see−through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the F" and L" lines on the reservoir.
If the level is low, add the coolant. (For
the coolant type, see Coolant type
selection" described below.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the L" line, add
coolant. Bring the level up to the F" line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, 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.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Use of improper coolants may damage
your engine cooling system.
Only use Toyota Super Long Life Coolant"
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life
hybrid organic acid technology. (Coolant
with long−life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
For the U.S.A.Toyota Super Long Life
Coolant" is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35
C
(−31 F).
For CanadaToyota Super Long Life
Coolant" is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
(−44 F).
NOTICE
Do not use plain water alone.

ful not to touch the radiator or con-
denser when the engine is hot.
NOTICE
To prevent damage to the radiator
and condenser, do not perform the
work by yourself.

To check the fluid level, simply look at
the see−through reservoir. 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 or
when the fluid level in the accumulator is
high.
If the reservoir needs frequent ref
illing, 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.
Checking the radiator and
condenser Checking brake fluid

440
Refilling brake fluid:1. Turn the engine switch off.
2. Depress the brake pedal more than 20 times (until the brake pedal resistance
decreases and pedal travel increases).
3. Remove the reservoir cover by hand. Add brake fluid up to the MAX" line.
If you do not follow the procedure above,
the reservoir may overflow.
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
hands or eyes. If fluid gets on your
hands or in your eyes, flush the af-
fected area with clean water immedi-
ately. If you still feel uncomfortable
with your hands or eyes, go to the
doctor.
NOTICE
If you spill some of the fluid, be sure
to wipe it off to prevent it from dam-
aging the parts or paintwork.

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 C80 C or 140 F175 F). You
may also check the level when the fluid
is cold (about room temperature,
10 C30 C or 50 F85 F) if the engine
has not been run for about five hours.
Checking power steering fluid

NOTICE
Be sure the engine and all accesso-
ries are off before performing main-
tenance.
 When checking the battery, remove
the ground cable from the negative
terminal (−" mark) first and rein-
stall it last.
 Be careful not to cause a short cir-
cuit with tools.
 Take care no solution gets into the
battery when washing it.
If the battery is disconnected or run
down, the power window, power back win-
dow and moon roof may not operate auto-
matically, the jam protection function will
not function correctly, and the back door
will not open after you reconnect, replace
or recharge the battery. In any of these
cases, you should normalize the power
window, power back window, back door
and moon roof. To normalize them, see
Power windows" on page 27, Power back
window" on page 30, Back door" on page
32 and Electric moon roof" on page 39
in Section 1−2.

If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See Fuse locations" on page 430 in Sec-
tion 7−1 for locations of the fuses.
Turn the engine switch and inoperative
component off. Pull the suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
page 468 in Section 8 for the functions
controlled by each circuit. Type 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 PWR
OUTLET" or HEATER NO.2" 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
to the rating as possible. 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 ve-
hicle for emergencies.
Checking and replacing fuses

453
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.
CAUTION
Never use a fuse with a higher am-
perage rating, or any other object, in
place of a fuse. This may cause ex-
tensive damage and possibly a fire.CY73025
If any washer does not work, the wash-
er tank may be empty. Check the wash-
er fluid level on the level gauge. If the
washer fluid level is below LOW" or
only slightly above the LOW" level,
add washer fluid.
For vehicles sold in Canada
If any washer does not work or low
windshield washer fluid level warning
light comes on, the washer tank may be
empty. Add washer fluid.You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below the 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.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
