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 fromdamaging the parts or paint.
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 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 CÐ80 C or 104 FÐ175 F). You
may also check the level when the fluid
is cold (about room temperature,
0 CÐ40 C or 32 FÐ104 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 ªCOLDº
range on the dipstick. Similarly, if it is
hot, the fluid level should be in the
ªHOTº 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 CÐ80 C or 140 FÐ175 F). You
may also check the level when the fluid
is cold (about room temperature,
10 CÐ30 C or 50 FÐ85 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 ªCOLDº
range. Similarly, if it is hot, the fluid level
should be in the ªHOTº 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.
Checking tire pressure
Keep your tire pressures at the proper
level.
The recommended cold tire pressures, tire
size and the cargo weight rating are given
in Section 8. Tire size and pressure are
also on the tire pressure label as shown.
You should check the tire pressures every
two weeks, or at least once a month. And
do not forget the spare!
