NOTE:
●Independent of the Maintenance Midner information, replace
the brake fluid every 3 years.●Inspect idle speed every 160,000 miles (256,000 km).●Adjust the valves during services A, B, 1, 2, or 3 if they are
noisy.Symbol Maintenance Sub Items

●Rotate tires
2●Replace air cleaner element
If you drive in dusty conditions, replace every 15,000
miles (24,000 km).●Replace dust and pollen filter
If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from
diesel-powered vehicles, replace every 15,000 miles
(24,000 km).●Inspect drive belt
3●Replace transmission and transfer fluid
4●Replace spark plugs●Replace timing belt and inspect water pump
If you drive regularly in very high temperatures (over
110°F, 43°C), in very low temperatures (under－20°F,－
29°C), or towing a trailer, replace every 60,000 miles (U.
S.)/100,000 km (Canada).●Inspect valve clearance
5●Replace engine coolant
6●Replace rear differential fluid
Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000
km), then every 15,000 miles (24,000 km).

Maintenance

The component parts in the engine
compartment are protected by the
cover. You may need to remove the
cover when you perform some
simple maintenance work.
Cover is secured by holding clips.
To remove the front bulkhead cover,
remove the holding clips with a flat-
tip screwdriver.

Engine Compartment Cover516

Unscrew and remove the engine oil
fill cap on top of the valve cover. Pour
in the oil slowly and carefully so you
do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment.
Reinstall the engine oil fill cap, and
tighten it securely. Wait a few
minutes, and recheck the oil level on
the engine oil dipstick. Do not fill
above the upper mark; you could
damage the engine.Recommended Engine Oil
Oil is a major contributor to your
engine's performance and longevity.
Always use a premium-grade 5W-20
detergent oil displaying the API
Certification 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
Acura motor oil in your vehicle.
Make sure the API Certification Seal
says‘‘For Gasoline Engines.’’
The oil viscosity or weight is
provided on the container's label.
5W-20 oil is formulated for year-
round protection of your vehicle to
improve cold weather starting and
fuel economy.

Maintenance

Synthetic Oil
You may use a synthetic motor oil if
it meets the same requirements
given for a conventional motor oil: it
displays the API Certification Seal
and it is the proper weight. You must
follow the oil and filter change
intervals shown on the multi-
information display.
Engine Oil Additives
Your vehicle does not require any oil
additives. Additives may adversely
affect the engine or transmission
performance and durability.Changing the Engine Oil and
Filter
Always change the oil and filter
according to the maintenance
messages shown on the multi-
information display. The oil and filter
collect contaminants that can
damage your engine if they are not
removed regularly.
Changing the oil and filter requires
special tools and access from
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lift for this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
mechanic.
1. Run the engine until it reaches
normal operating temperature,
then shut it off.
2. Open the hood, and remove the
engine oil fill cap. Remove the oil
drain bolt and washer from the
bottom of the engine. Drain the oil
into an appropriate container.

3. Remove the oil filter, and let the
remaining oil drain. A special
wrench (available from your
dealer) is required.
Make sure the oil filter gasket is
not stuck to the engine block. If it
is, remove it before installing a
new oil filter.4. Install a new oil filter according to
the instructions that come with it.
Make sure to clean off any dirt and
dust on the connecting surface of a
new oil filter.
5. Put a new washer on the drain
bolt, then reinstall the drain bolt.
Tighten the drain bolt to:
29 lbf·ft (39 N·m, 4.0 kgf·m)
6. Refill the engine with the
recommended oil.
Engine oil change capacity
(including filter):
4.5 US qt (4.3 L)7. Reinstall the engine oil fill cap.
Start the engine. The oil pressure
indicator should go out within 5
seconds. If it does not, turn off the
engine, and check your work.
8. Let the engine run for several
minutes, then check the drain bolt
and oil filter for leaks.
9. Turn off the engine and let it sit for
several minutes, then check the oil
level on the dipstick. If necessary,
add more oil.
Improper disposal of engine oil can be
harmful 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.

Maintenance

Adding Engine CoolantIf 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 for
leaks.Always use Honda Long-life Anti-
freeze/Coolant Type 2. This coolant
is pre-mixed with 50 percent
antifreeze and 50 percent water.
Never add straight antifreeze or plain
water.
If Honda antifreeze/coolant 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 for aluminum
engines. Continued use of any non-
Honda coolant can result in
corrosion, causing the cooling
system to malfunction or fail. Have
the cooling system flushed and
refilled with Honda antifreeze/
coolant as soon as possible.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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.
