Inspect front and rear brakes
Check parking brake adjustment
Inspect these items: Tie rod ends, steering gear box, and boots
Suspension components
Driveshaft boots
Brake hoses and line (including ABS/VSA)
All fluid levels and condition of fluids
Exhaust system
Fuel lines and connections Maintenance Sub Items
Rotate tires
Replace air cleaner element If you drive in dusty conditions, replace every
15,000 miles (24,000 km).
Replace dust and pollen filter 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).
Inspect drive belt
Replace transmission fluid
Replace transmission and transfer fluid
Replace spark plugs
Replace timing belt and inspect water pump If you drive regularly in very high temperatures (over
110°F, 43°C), or in very low temperatures (under20°F, 29°C), replace every 60,000 miles (U.S.)/
100,000 km (Canada).
Inspect valve clearance
Replace engine coolant
Replace rear differential fluid Driving in mountainous areas at very low vehicle
speeds results in higher level of mechanical (shear)
stress to fluid. 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).

Always use Honda Long-lif e Anti-
f reeze/Coolant Type 2. This coolant
is pre-mixed with 50 percent
antif reeze and 50 percent distilled
water. Never add straight antif reeze
or plain water.
If Honda antifreeze/coolant is not
available, you may use another
major-brand non-silicate coolant as
recommended for aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malfunction or fail. Have the cooling
system flushed and refilled with
Honda antifreeze/coolant as soon
Reinstall the engine oil f ill cap.
Start the engine. The oil pressure
indicator should go out within 5
seconds. If it does not, turn of f the
engine and check your work.
Let the engine run f or several
minutes, then check the drain bolt
and oil f ilter f or leaks.
Turn of f the engine, let it sit f or
several minutes, then check the oil
level on the dipstick. If necessary,
add more oil.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks.
To access the radiator reserve tank,

Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.If the washer f luid is low, a ‘‘LOW
WASHER FLUID’’ message appears
on the multi-information display.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition the blade edges.
To check washer f luid level, cover
the reservoir cap center hole with
your f inger while lif ting the cap and
the attached measuring tube. The
washer f luid level in the tube will
indicate the washer f luid level in the
reservoir.

Do not use engine antif reeze or a
vinegar/water solution in the

can damage your vehicle’s paint, while
a vinegar/water solution can damage

commercially-available windshield
washer f luid.

The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.
You need to remove the lef t engine
compartment cover to check the
f luid level (see page ).
Check the f luid level in the
reservoirs monthly. There are up to
two reservoirs, depending on the
model. They are:
Brake f luid reservoir (all models)
Clutch f luid reservoir
(manual transmission models
only)
To access the reservoirs, remove the
lef t engine compartment cover (see
page ).
You will also see a ‘‘LOW BRAKE
FLUID’’ message on the multi-
inf ormation display. Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage. Using any non-Honda brake f luid can
cause corrosion and decrease the lif e
of the system. Have the brake
system f lushed and ref illed with
Honda Heavy Duty Brake Fluid
DOT 3 as soon as possible.
Independent of the Maintenance
Minder inf ormation, replace the
brake f luid every 3 years. 542
