Power Steering
Check the level when the engine is
cold. Look at the side of the
reservoir. The fluid should be
between the UPPER LEVEL and
LOWER LEVEL. If it is below the
LOWER LEVEL, add power steering
fluid to the UPPER LEVEL.
Maintenance
UPPER LEVEL
LOWER LEVEL
Always use Genuine Honda Power
Steering Fluid. If it is not available,
you may use another power steering
fluid as an emergency replacement.
However, continued use can cause
increased wear and poor steering in
cold weather. Have the power
steering system flushed and refilled
with Honda PSF as soon as possible.
A low power steering fluid level can
indicate a leak in the system. Check
the fluid level frequently and have
the system inspected as soon as
possible.
NOTICE
Turning the steering wheel to full left
or right lock and holding it there can
damage the power steering pump.
