Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
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.

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
Coolantº 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 -35C (- 31F). When it is extreme-
ly cold, to provide protection down to
about -50C (- 58F), 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.
Checking brake fluid
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
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
If cold add
If cold O.K.
If hot add
If hot O.K.
Check the fluid level on the dipstick. If
necessary, add automatic transmission
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 (60CÐ80C or 140FÐ175F). 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.
a. Clean all dirt from outside of the reser-
voir tank.
b. Remove the reservoir cap by turning it
counterclockwise and wipe the dipstick
clean.c. Reinstall the reservoir cap.
d. Remove the reservoir cap again and
look at the fluid level. If the fluid is cold,
the level should be in the COLDº range
on the dipstick. 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.
e. After replacing the reservoir cap, visu-
ally 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.
