Power Steering, Air Cleaner Element
UPPER LEVEL
6-cylinder models
LOWER LEVEL
Maintenance
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.
Air Cleaner Element
The air cleaner element should be
cleaned or replaced according to the
time and distance recommendations
in the maintenance schedule.
Cleaning (Severe Conditions)
Clean the air cleaner element by
blowing compressed air through it in
the opposite direction to normal air
flow. If you do not have access to
compressed air (such as a service
station), ask your Honda dealer to do
this service.
Follow the replacement procedure
for removal and reinstallation.
