When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear
an unusual noise. A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired.

How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level
on the dipstick.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the level up
to the
mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants”
in the Index. Always use the proper fluid.
Failure to use the proper fluid can cause leaks and
dam’age hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use.
If you will be
operating your vehicle
in an area where the temperature
may
fall below freezing, use a fluid that has sufficient
protection
against freezing.
Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY Add
washer fluid until the tank
is full.
