Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment.Reinstall the engine oil f ill cap, and
tighten it securely. Wait a f ew
minutes, and recheck the oil level on
the engine oil dipstick. Do not f ill
above the upper mark; you could
damage the engine.
Oil is a major contributor to your
engine’s perf ormance and longevity.
Your vehicle is equipped with a high-
perf ormance turbocharged engine
that requires the use of synthetic
motor oil. Always use Mobil 1
5W-30 or an equivalent oil that meets
the Acura HTO-06 standard. Not all
synthetic oils will meet this standard.
Only use oils that display the HTO-
06 standard on the label.
Failure to use Mobil 1
or an
equivalent oil that meets the HTO-06
standard can lead to a reduction in
engine perf ormance or durability,
and can cause engine damage not
covered by your warranty.

Always change the oil and f ilter
according to the maintenance
messages shown on the inf ormation
display or multi-inf ormation display
(depending on models). The oil and
f ilter collect contaminants that can
damage your engine if they are not
removed regularly.Run the engine until it reaches
normal operating temperature,
then shut it off.
Open the hood, and remove the
engine oil f ill cap. Remove the oil
drain bolt and washer f rom the
bottom of the engine. Drain the oil
into an appropriate container.Remove the oil f ilter, and let the
remaining oil drain. A special
wrench (available from your
dealer) is required.
Install a new oil f ilter according to
the instructions that come with it. Check the oil f ilter to make sure
its gasket did not stick to the f ilter
base. A stuck gasket could cause
an oil leak.
Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
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
technician. 1.

change your own oil, please dispose of
the used oil properly. Put it in a sealed
container and take it to a recycling

If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If you need to park your vehicle f or
an extended period (more than 1
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors. Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.

To minimize sticking, apply a

Let the vehicle sit for a minute.
Op en the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers. If
the charging system
indicator comes on brightly
wh en the engine is running, the
battery is not being charged.
Safely
pull off the road, and shut
off the engine. Turn on the hazard
warning lights.
This
indicator should never
come on when the engine is
running. If it starts flashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action.
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
befo re you can continue driving
(see on page
). You
will also see a ‘‘CHECK
CHARGI NG SYSTEM’’ message on
the multi-information display (see
page ).
Immediately turn off all electri cal
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.
If
necessary, add oil to bring the
level back to the full mark on the
dipsti ck (see page ).
You
will also see an ‘‘OIL
PRESSURE LOW’’ message on the
multi-info rmation display (see page
). 1.
