CHECKING BRAKE FLUID
63G002a

CHASSIS
421 To check the fluid level, simply look at the
see±through reservoir. The level should be between
the ºMAXº and ºMINº lines on the tank.
It is normal for the brake fluid level to go down slightly as
the brake pads wear or when the fluid level in the
accumulator is high.
If the reservoir needs frequent refilling, it may indicate a
serious mechanical problem.
If the level is low, add FMVSS No.116 DOT 3 or SAE
J1703 brake fluid to the brake reservoir.
Refilling brake fluid:
1. Turn the ignition switch off.
2. Depress the brake pedal more than 40 times.
3. Remove the reservoir cap by hand. Add brake fluid
up to the ºMAXº 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 efficiency.

CAUTION
Take care when filling the reservoir because brake fluid
can harm your hands or eyes and damage painted
surfaces. If fluid gets in your hands or eyes, flush them
with clean water.
NOTICE
If you spill some of the fluid, be sure to wipe it off
to prevent it from damaging the parts or
paintwork.

Check the fluid level through the reservoir. 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 (60C ± 80C or 140F ± 175F). You may
also check the level when the fluid is cold (about room
temperature, 10C ± 30C or 50F ± 85F) if the engine
has not been run for about five hours.

Clean all dirt off the reservoir and look at the fluid level.
If the fluid is cold, the level should be in the ºCOLDº
range. Similarly, if it is hot, the fluid level should be in the
ºHOTº range. If the level is at the low side of the
appropriate range, add automatic transmission fluid
DEXRON
II or III to bring the level within the range.
To remove the reservoir cap, turn it counterclockwise
and lift up. To reinstall it, turn it clockwise. After
replacing the reservoir cap, visually check the steering
box case, vane pump and hose connections for leaks or
damage.

CAUTION
The reservoir may be hot so be careful not to burn
yourself.

Avoid overfilling, or the power steering could be
damaged.

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 (60C ± 80C or 140F ± 175F). You may
also check the level when the fluid is cold (about room
temperature, 10C ± 30C or 50F ± 85F) if the engine
has not been run for about five hours.
