Check the f luid level with the
transmission at normal operating
temperature and the car sitting on
level ground. Remove the
transmission f iller bolt and caref ully
f eel inside the bolt hole with your
f inger. The f luid level should be up
to the edge of the bolt hole. If it is
not, add Honda Manual Transmis-
sion Fluid (MTF) until it starts to
run out of the hole. Reinstall thef iller bolt and tighten it securely.
If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certif ication seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives, and continued use can
cause stiffer shifting. Replace as
soon as it is convenient.
The transmission should be drained
and ref illed with new f luid according

Tires that are marked ‘‘M S’’ or
‘‘All Season’’ on the sidewall have an
all-weather tread design. They
should be suitable f or most winter
driving conditions. Tires without
these markings are designed f or
optimum traction in dry conditions.
They may not provide adequate
perf ormance in winter driving.
For the best perf ormance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions. If you mount snow tires on your
Honda, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tiresonallfourwheelstobalance
your car’s handling in all weather
conditions. Keep in mind the traction
provided by snow tires on dry roads
may not be as high as your car’s
original equipment tires. You should
drive cautiously even when the roads
are clear. Check with the tire dealer
f or maximum speed recommenda-
tions.Mount snow chains on your tires
when required by driving conditions
or local laws. Install them only on the
f ront tires.
Because your car has limited tire
clearance, Honda strongly
recommends using the chains listed
below, made by Security Chain
Company (SCC).

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 car,
it is best to use a solid type. Some
liquid air f resheners contain chemi-
cals 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.
