Checking Engine Oil
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The oil dipstick handle is a
yellow ring located in the
engine compartment
toward the passenger side
of the vehicle. See
Engine Compartment
Overview on page 5-10for
more information on
location.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil
dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
5-11

Power Steering Fluid
The power steering reservoir is located near the front of
the engine compartment on the driver's side of the
vehicle.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering ¯uid
unless you suspect there is a leak in the system or
you hear an unusual noise. A ¯uid loss in this system
could indicate a problem. Have the system inspected
and repaired. See
Engine Compartment Overview
on page 5-10for reservoir location.
How to Check Power Steering Fluid
Turn the key off, let the engine compartment cool down,
wipe the cap and the top of the reservoir clean, then
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 ¯uid level on the dipstick.
The level should be between the ADD and FULL marks.
If necessary, add only enough ¯uid to bring the level
up to the proper range.
What to Use
To determine what kind of ¯uid to use, seePart D:
Recommended Fluids and Lubricants on page 6-33.
Always use the proper ¯uid. Failure to use the proper
¯uid can cause leaks and damage hoses and seals.
