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. Your coolant
must contain ethylene−glycol type coolant
for a proper corrosion protection of your
engine that contains aluminum
components. Use “TOYOTA Long Life
Coolant” or equivalent.
In addition to preventing freezing and
subsequent damage to the engine, this
type of coolant will also prevent corrosion.
Further supplemental inhibitors or additives
are neither needed nor recommended.
Read the coolant container for information
on freeze protection. Follow the manufac-
turer’s directions for how much to mix
with plain water (preferably demineralized
water or distilled water). The total capacity
of the cooling system is given in Section
8. We recommend to use 50% solution for
your Toyota, to provide protection down to
about
−35 C ( −31 F). When it is extreme-
ly cold, to provide protection down to
about −50 C ( −58 F), 60% solution is rec-
ommended. Do not use more than 70%
solution for better coolant performance.NOTICE
Do not use alcohol type antifreeze or
plain water alone.
If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to Toyota dealer.
CAUTION
To prevent yourself from burning, be
careful not to touch the radiator or
condenser when the engine is hot.
NOTICE
To prevent damage to the radiator
and condenser, do not perform the
work by yourself.

condenser

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 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.
The 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 yourself from burning,
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.
