To add oil, unscrew and remove the
engine oil f ill cap on top of the valve
cover. Pour in the oil, and install the
engine oil f ill cap. Tighten it securely.
Wait a f ew minutes and recheck the
oil level. Do not f ill above the upper
mark; you could damage the engine.Oil is major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade
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. It is
highly recommended that you use
Honda Motor Oil in your vehicle f or
as long as you own it.
Make sure the API Certif ication Seal
says ‘‘For Gasoline Engines.’’

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.
The numbers on the container's label
Select the oil for your vehicle
according to this chart. 5W-20 oil is f ormulated f or year-
round protection of your Acura, to
improve cold weather starting, and
to help your engine use less f uel.
If 5W-20 oil is not available, a 5W-30
oil may be used. However, it should
be replaced with 5W-20 at the next
oil change.

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.Run the engine until it reaches
normal operating temperature,
then shut it off.
Your Acura does not need any oil
additives. Purchasing additives f or
the engine or transmission will not
increase your car’s perf ormance or
longevity. It only increases the cost
of operating your car. 1.

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.
This coolant should always be a
mixtureof 50percentantifreezeand
50 percent water. Never add straight
antif reeze or plain water.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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.

CONT INUED
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.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.
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.
Thecoolingsystemshouldbe
completely drained and ref illed with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only use
Honda All Season Antif reeze/
Coolant Type 2. Use of any non-
Hondacoolantorplainwatercan
result in corrosion and deposits in
the cooling system.
Draining the coolant requires access
to the underside of the car. Unless
you have the tools and knowledge,
you should have this maintenance
done by a skilled mechanic.
