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.

3. Remove the oil filter, and let theremaining 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 (39.2 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.

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.

6. Pour coolant into the reserve tank.Fill it to halfway 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 vehicle's
cooling system. They may not be
compatible with the coolant or
engine components. Windshield Washers
Check and fill the windshield washer
reservoir according to the warning
message on the multi-information
display.
If the washer fluid is low, a
‘‘LOW
WASHER FLUID ’’message appears
on the multi-information display.
Fill the reservoir with a good-quality
windshield washer fluid. This
increases the cleaning capability and
prevents freezing in cold weather.
When you refill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer fluid
on a clean cloth. This will help to
condition the blade edges.
Do not use engine antifreeze or a
vinegar/water solution in the
windshield washer reservoir. Antifreeze
can damage your vehicle's paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer fluid.

Check the fluid level with the engine
at normal operating temperature.1. Park the vehicle on level ground. Start the engine, let it run until the
radiator fan comes on, then shut
off the engine. For accurate
results, wait about 60 seconds (but
no longer than 90 seconds) before
doing step 2.
2. Remove the dipstick (yellow loop)from the transmission, and wipe it
with a clean cloth.
3. Insert the dipstick all the way intothe transmission securely as
shown in the illustration.
4. Remove the dipstick and check the fluid level. It should be between
the upper and lower marks.

Power Steering FluidCheck the level on the side of the
reservoir when the engine is cold.
The fluid should be between the
UPPER LEVEL and LOWER LEVEL.
If not add power steering fluid to the
UPPER LEVEL mark.
Pour the fluid slowly and carefully so
you do not spill any. Clean up any
spills immediately; it could damage
components in the engine
compartment.Always use Acura Power Steering
Fluid. You may use another power
steering fluid as an emergency
replacement, but have the power
steering system flushed and refilled
with Acura PSF as soon as possible.
A low power steering fluid level can
indicate a leak in the system. Check
the fluid level frequently, and have
the system inspected as soon as
possible.
If you are not sure how to add fluid,
contact your dealer.
Turning the steering wheel to full left or
right lock and holding it there can
damage the power steering pump.
Timing Belt
The timing belt should be replaced at
the intervals shown in the
maintenance minder schedule.
Replace the timing belt every 60,000
miles (U.S.) or every 100,000 km
(Canada) if you regularly drive your
vehicle in any of the following
conditions:
●In very high temperatures
(over 110°F, 43°C).●In very low temperatures
(under
-20°F, -29°C).●Frequently tow a trailer.

Diagnosing why the engine won't
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position or on models with keyless
access system, press the engine
start/stop button to set START mode
(see page 194):●You hear nothing, or almost
nothing. The engine's starter
motor does not operate at all, or
operates very slowly.●You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine
does not start up and run.Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to
the START (III) position or on
models with keyless access system,
press the engine start/stop button to
set START mode (see page 194), you
do not hear the normal noise of the
engine trying to start. You may hear
a clicking sound, a series of clicks, or
nothing at all.
Check these things:
●Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
●Turn the ignition switch to the ON
(II) position or on models with
keyless access system, press the
engine start/stop button to set ON
mode (see page 194). Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
Jump Starting
on page 587.●Turn the ignition switch to the
START (III) position or on models
with keyless access system, press
the engine start/stop button to set
START mode (see page 194). If the
headlights do not dim, check the
condition of the fuses. If the fuses
are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. See
Emergency Towing on page 602.
