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

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.

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.
