Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade 5W-20
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements.
Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment. Install the engine oil
f ill cap, and tighten it securely. Wait
a f ew minutes, and recheck the oil
level (see page ). Do not f ill
above the upper mark; you could
damage the engine. Acura Motor Oil is the pref erred
5W-20 lubricant f or your vehicle. It is
highly recommended that you use
Acura Motor Oil in your vehicle f or

If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.

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.
Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.
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.
If the washer f luid is low, a ‘‘LOW
