) Improper disposal of engine oil can be
harmf ul to the environment. If you
change your own oil, please dispose of
the used oil properly. Put it in a sealed
container and take it to a recycling
center. Do not discard it in a trash bin
or dump it on the ground.

CONT INUED
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water. It
does not require any additional
mixing. If it is not available, you may
use another major-brand non-silicate
coolant as a temporary replacement.
Make sure it is a high-quality coolant
recommended f or aluminum engines.
However, 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 reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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.
The coolant you add should always
be a mixture of 50 percent antif reeze
and 50 percent water. Never add
straight antif reeze or plain water.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system. Make sure the engine and radiator
are cool.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Remove the radiator cap by
pushing down and turning
counterclockwise. Put the radiator cap back on.
Tighten it f ully.
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 car’s cooling
system. They may not be compatible
with the coolant or engine compo-
nents.
Pourthecoolantslowlyand
caref ully so you do not spill. Clean
up any spills immediately. Spilled
coolant could damage components
in the engine compartment.
