2003 HONDA ODYSSEY Owners Manual

Always use Honda Power Steering
Fluid. If it is not available, you may
use another power steering f luid as
an emergency replacement.
However, continued use can cause
increased wear and poor steering in
cold weather. Have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently and have
the system inspected as soon as
possible.
Check the level when the engine is
cold. Look at the side of the
reservoir. The f luid should be
between the UPPER LEVEL and
LOWER LEVEL. If it is below the
LOWER LEVEL, add power steering
f luid to the UPPER LEVEL.
Pour the f luid slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled f luid could
damage components in the engine
compartment.
