Refilling brake fluid:
1. Turn the ignition switch off.
2. Depress the brake pedal more than 40 times.
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 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 on the dipstick. If
necessary, add automatic transmission
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 (40 C—80 C or 104 F—175 F). You
may also check the level when the fluid
is cold (about room temperature,
0 C—40 C or 32 F—104 F) 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 “COLD”
range on the dipstick. Similarly, if it is
hot, the fluid level should be in the
“HOT” range. If the level is at the low
side of either range, add automatic
transmission fluid DEXRON II 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.

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. Clean all dirt from outside of the reservoir
tank and look at the fluid level. If the fluid
is cold, the level should be in the “COLD”
range. Similarly, if it is hot, the fluid level
should be in the “HOT” range. If the level
is at the low side of either range, add
automatic transmission fluid DEXRON
II
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.
