If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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.
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. 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.

tighten it fully.
Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components. Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
The washer level indicator will come
on when the level is low (see page
).
If the washer f luid is low, a
‘‘WASHER FLUID LOW’’ message
appears on the multi-inf ormation
display.
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
