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.
Required Engine Oil
Oil is a major contributor to your
engine's performance and longevity.
Your vehicle is equipped with a high-
performance 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 performance or durability,
and can cause engine damage not
covered by your warranty.

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
technician.
1. Run the engine until it reachesnormal 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.
4. Check the oil filter to make sure its gasket did not stick to the filter
base. A stuck gasket could cause
an oil leak.
5. Install a new oil filter according to the instructions that come with it.

(including filter):
5.0 US qt (4.7 L) 8. 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.
9. Let the engine run for several minutes, then check the drain bolt
and oil filter for leaks.
10. 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.

1. Make sure the engine and radiatorare cool.
2. Relieve any pressure in the cooling system by turning the radiator cap
counterclockwise, without
pressing down.
3. Remove the radiator cap by pushing down and turning
counterclockwise.
4. The coolant level should be up tothe base of the filler neck. Add
coolant if it is low.
Pour the coolant slowly and
carefully so you do not spill any.
Clean up any spills immediately; it
could damage components in the
engine compartment. 5. Put the radiator cap back on, and
tighten it fully.
6. Pour coolant into the reserve tank. Fill it 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.

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.Automatic Transmission Fluid
The transmission should be drained
and refilled with new fluid when this
service is shown on a maintenance
message on the multi-information
display.
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.
5. If the level is below the lowermark, remove the fill plug, then
add the fluid into the fill hole to
bring it to the level between the
upper and lower marks on the
dipstick.
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 ATF-Z1 (automatic
transmission fluid).
Use only Acura ATF-Z1 (automatic
transmission fluid). Do not mix with
other transmission fluids.
Using transmission fluid other than
Acura ATF-Z1 may cause deterioration
in transmission operation and
durability, and could result in damage
to the transmission.
Damage resulting from the use of
transmission fluid other than Acura
ATF-Z1 is not covered by the Acura
new vehicle warranty.
6. Insert the dipstick all the way back
into the transmission securely as

Check 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.
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.
