Look at the see- through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the Fº and Lº lines on the reservoir.
If the level is low, add the coolant. (For
the coolant type, see Coolant type
selectionº described below.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the Lº line, add
coolant. Bring the level up to the Fº 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 Coolantº
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.ÐToyota Super Long Life
Coolantº is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about -35C
(- 31F).
For CanadaÐToyota Super Long Life
Coolantº is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about -42C
(- 44F).
NOTICE
Do not use plain water alone.
Toyota recommends Toyota Super Long
Life Coolantº, which has been tested to
ensure that it will not cause corrosion nor
result in malfunction of your engine
coolant system with proper usage. Toyota
Super Long Life Coolantº is formulated
with long- life hybrid organic acid
technology and has been specifically
designed to avoid engine cooling system
malfunction on Toyota vehicles.
Please contact your Toyota dealer for
further details.

If either of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to a Toyota dealer.
CAUTION
To prevent burning yourself, be care-
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 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 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 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 DEXRONII 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 (80C or 175F). You may also check
the level when the fluid is cold (about
room temperature, 10CÐ30C or
50FÐ85F) if the engine has not been
run for about five hours.Clean all dirt from the outside of the res-
ervoir tank and look at the fluid level. If
the fluid is cold, the level should be in the
COLDº range. Similarly, if it is hot, the
fluid level should be in the HOTº range.
If the level is at the low side of either
range, add automatic transmission fluid
DEXRONII or III to bring the level within
the range.
To remove the reservoir cap, turn it coun-
terclockwise and lift up. To reinstall it,
turn it clockwise. After replacing the reser-
voir 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.

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 (- º 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 moon roof may not operate
automatically and the jam protection func-
tion will not function correctly after you
reconnect, replace or recharge the battery.
In any of these cases, you should normal-
ize the moon roof. To normalize the moon
roof, see Electric moon roofº on page 36
in Section 1- 2.

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.

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 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.
The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens becomes wet in the rain or
in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lens, just like the
windshield fogs up in the rain. However, if
there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your
Toyota dealer.
