To check the fluid level, simply look at
the seethrough 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. 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 cap by
hand. Fill the brake fluid to the dotted
line. This brings the fluid to the correct
level when you put the cap 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 r
eservoir
because brake fluid can harm your
eyes and damage painted surfaces. If
fluid gets in your eyes, flush your
eyes with clean water immediately. If
you still feel uncomfortable with your
eyes, go to the doctor.
NOTICE
If you spill some of the fluid, be sure
to wash it off with water to prevent
it from damaging the parts or paint.

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.

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.

During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.

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.
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 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.
*: When equippedThe following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the ignition switch and
light switch are off. Use bulbs with the
wattage ratings given in the table.
CAUTION
To prevent from burning yourself,
do not replace the light bulbs while
they are hot.
Halogen bulbs have pressurized gas
inside and require special handling.
They can burst or shatter if
scratched or dropped. Hold a bulb
only by its plastic or metal case.
Do not touch the glass part of a
bulb with bare hands.
NOTICE
Only use a bulb of the listed type.

as necessary.
Generally, it is necessary to change
automatic transmission fluid only if your
vehicle is driven under one of the Special
Operating Conditions listed in your
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”. When
changing the automatic transmission fluid,
use only Toyota Genuine ATF Type TIV
(ATF JWS3309 or NWS6500) to aid in
assuring optimum transaxle performance. Notice: Using automatic transmission
fluid other than Toyota Genuine ATF
Type TIV may cause deterioration in
shift quality, locking up of your trans-
mission accompanied by vibration, and
ultimately damage the automatic trans-
mission of your vehicle.
