Always change the oil and f ilter
accordingtothetimeanddistance
(miles/kilometers) recommenda-
tions in the maintenance schedule.
The oil and f ilter collect contami-
nants that can damage your engine if
they are not removed regularly.
Changing the oil and f ilter requires
special tools and access f rom
underneath the car. The car should
be raised on a service station-type
hydraulic lif t f or this service. Unless
you have the knowledge and proper
equipment, you should have this
maintenance done by a skilled
mechanic.
You may use a synthetic motor oil if
it meets the same requirements
given f or a conventional motor oil: it
displays the API Certif ication Seal,
and it is the proper weight as shown
on the chart. When using synthetic
oil, you must f ollow the oil and f ilter
change intervals given in the
maintenance schedule.
Your Acura does not require any oil
additives. Additives may adversely
af f ect your engine’s or transmission’s
perf ormance and durability.

change your own oil, please dispose of
the used oil properly. Put it in a sealed

center. Do not discard it in a trash bin
or dump it on the ground.

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. 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.

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.

Make sure the engine and
radiator are cool.
Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system.
Remove the radiator cap by
pushing down and turning
counterclockwise.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.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.

The windshield washer reservoir is
located behind the driver’s side
headlight. Check the reservoir’s f luid
level by removing the cap and
looking at the level gauge attached
to the cap.
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.
Remove the dipstick (yellow loop)
f rom the transmission and wipe it
with a clean cloth. Park the car on level ground. Shut
