µµ 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.
Check the f luid level in the brake
f luid reservoir monthly.
The brake f luid should be replaced
according to the time recommenda-
tion in the maintenance schedule.
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. However, the use of
any non-Honda brake fluid can cause
corrosion and decrease the lif e of the

f lushed and ref illed with Honda
Heavy Duty Brake Fluid DOT 3 as
soon as possible.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage.
If it is not, slowly add proper f luid
until it starts to run out of the hole.
Reinstall the f iller plug and tighten it
securely.

Frequent washing helps preserve
your vehicle’s beauty. Dirt and grit
can scratch the paint, while tree sap
and bird droppings can permanently
ruin the f inish.
Wash your vehicle in a shady area,
not in direct sunlight. If the vehicle is
parked in the sun, move it into the
shade and let the exterior cool down
bef ore you start.When you have washed and rinsed
the whole exterior, dry it with a
chamois or sof t towel. Letting it
air-dry will cause dulling and water
spots.
Rinse the vehicle thoroughly with
cool water to remove loose dirt.
Only use the solvents and cleaners
recommendedinthisOwner’s
Manual. Fill a bucket with cool water. Mix
in a mild detergent, such as
dishwashing liquid or a product
made especially f or car washing.
Wash the vehicle using the water
and detergent solution and a sof t-
bristle brush, sponge, or sof t cloth.
Start at the top and work your way
down. Rinse f requently.
Check the body f or road tar, tree
sap, etc. Remove these stains with
tar remover or turpentine. Rinse it
of f immediately so it does not
harm the f inish. Remember to re-
wax these areas, even if the rest of
the vehicle does not need waxing.As you dry the vehicle, inspect it f or
chips and scratches that could allow
corrosion to start. Repair them with
touch-up paint (see page ).

Chemical solvents and strong cleaners
can damage the paint, metal, and
plastic on your vehicle. The radio antenna on your vehicle does
not need to be removed when you use a
‘‘drive-through’’ car wash. However, if
you remove the antenna, make sure to
reinstall it and tighten it securely using
an appropriate tool.

Dirt build-up in the loops of the seat
belt anchors can cause the belts to
retract slowly. Wipe the insides of
the loops with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.Clean the windows, inside and out,
with a commercially-available glass
cleaner. You can also use a mixture
of one part white vinegar to ten parts
water. This will remove the haze that
builds up on the inside of the
windows. Use a sof t cloth or paper
towels to clean all glass and clear
plastic surf aces.If you want to use an air f reshener/
deodorizer in the interior of your
vehicle, it is best to use a solid type.
Some liquid air f resheners contain
chemicals that may cause parts of
the interior trim and f abric to crack
or discolor.
If youusealiquidairfreshener,
make sure you f asten it securely so it
does not spill as you drive.
