If the message ‘‘SERVICE dUE NOW’’ does not appear more than 12 months
after the display is reset, change the engine oil every year.
See information on maintenance and emissions warranty on page .Independent of the maintenance messages in the information display,
replace the brake fluid every 3 years.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2, or 3 only if they are noisy.
NOTE: 1:

If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from diesel-
powered vehicles, replace every 15,000 miles (24,000 km).
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded results in higher
transmission and transfer temperatures. This requires
transmission and transfer fluid changes more frequently
than recommended by the Maintenance Minder.
If you regularly drive your vehicle under these conditions, have
the transmission and transfer fluid changed every 30,000 miles
(48,000 km).
If you drive regularly in very high temperatures (over 110°F,
43°C), in very low temperatures (under-20°F, -29°C), or towing a
trailer, replace every 60,000 mile (U.S.)/100,000 km (Canada)
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded causes more
mechanical (shear) stress and fluid deterioration. This requires
differential fluid changes more frequently than recommended
by the Maintenance Minder. If you regularly drive your vehicle
under these conditions, have the differential fluid changed at
7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

The timing belt should be replaced
at the intervals shown in the
maintenance minder schedule.
Replace the belt at 60,000 miles (U.S.)
or 100,000 km (Canada) if you
regularly drive your vehicle in one or
more of these conditions:
Remove the cover, then check the
level on the side of the reservoir
when the engine is cold.
The f luid should be between the
UPPER LEVEL and LOWER LEVEL.
If not, add power steering f luid to the
UPPER LEVEL mark, and put the
cover back in place. Pour the f luid slowly and caref ully so
you do not spill any. Clean up any
spill immediately; it could damage
components in the engine
compartment.
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.
Always use Honda Power Steering
Fluid. You may use another power
steering f luid as an emergency
replacement, but have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.

outside through the heating and
cooling system/climate control
system.
Have your dealer replace this filter
when this service is indicated by a
maintenance message on the
inf ormation display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the airf low
from the heating and cooling
system/climate control system
becomeslessthanusual.Check the condition of the wiper
blades at least every six months.
Replace them if you f ind signs of
cracking in the rubber, areas that are
getting hard, or if they leave streaks
and unwiped areas when used.
To replace a wiper blade:
To raise the wiper arm, turn the
ignition switch to the ON (II)
position and activate the wipers
(see page ). When the wipers

protective clear-coat that keeps
the aluminum f rom corroding and
tarnishing. Cleaning the wheels
with harsh chemicals (including
some commercial wheel cleaners)
or a stif f brush can damage the
