*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and

from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).

*4: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperature.

This requires transmission fluid changes more frequently than recommended by the Maintenance
Minder. If you regularly drive your vehicle under this condition, have the transmission fluid changed at
30,000 miles (48,000 km), then every 25,000 miles (40,000 km).

*5: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under

-20°F, -29°C), replace every 60,000 miles (100,000 km).

*6: Driving in mountainous areas at very low vehicle speeds results in higher level of mechanical (Shear)

stress to fluid. This requires Twin Motor Unit fluid changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under this condition, have the Twin Motor Unit
fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

Recommended Engine Oil

Use a genuine engine oil or another commercial engine oil of suitable type and
viscosity (for the ambient temperature) as shown in the image that follows.

Oil is a major contributor to your engine’s performance and longevity. If you drive
the vehicle with insufficient or deteriorated oil, the engine may fail or be damaged.

Synthetic oil

You may also use synthetic motor oil if it is labeled with the API Certification Seal
and is the specified viscosity grade.

run beforehand. If the engine has been running, wait approximately three minutes
before you check the oil.

1.

Remove the dipstick (orange).

2.

Wipe the dipstick with a clean cloth or
paper towel.

3.

Insert the dipstick back all the way into its
hole.

4.

Remove the dipstick again, and check the
level. It should be between the upper and
lower marks. Add oil if necessary.

Open the hood and remove the engine oil
fill cap.

3.

Remove the drain bolt and washer from
the bottom of the engine, and drain the
oil into a suitable container.

4.

Remove the oil filter and dispose of the
remaining oil.

5.

Check that the filter gasket is not stuck to
the engine contact surface.

u

If it is stuck, you must detach it.

Changing the Engine Oil and Oil Filter

NOTICE

You may damage the environment if you do not
dispose of the oil in a suitable way. If you are
changing the oil by yourself, appropriately dispose of
the used oil. Put the oil in a sealed container and take
it to a recycling center. Do not throw the oil away
into a garbage can or onto the ground.

You will need a special wrench to replace the oil
filter. You can buy this wrench from a dealer.

When installing the new oil filter, follow the
instructions supplied with the oil filter.

Reinstall the engine oil fill cap. Start the engine. The
low oil pressure indicator should go off within five
seconds. If it does not, turn off the engine, and check
your work.

Cooling System

Continued

Main

ce

Cooling System

This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.

We recommend you check the engine coolant level every time you refuel. Check the
reserve tank first. If it is completely empty, also check the coolant level in the
radiator. Add the engine coolant accordingly.

1. Make sure the engine and radiator are

cool.

2.

Check the amount of coolant in the reserve
tank.

u

If the coolant level is below the

MIN

mark, add the specified coolant until it
reaches the

MAX

mark.

3.

Inspect the cooling system for leaks.

Specified coolant: Acura Long Life Antifreeze/Coolant Type 2

Cooling System

NOTICE

Genuine Acura engine coolant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as about -31°F (-35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult a dealer for
details.

If Acura antifreeze/coolant is not available, you may
use another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Acura coolant can result in
corrosion, causing the cooling system to malfunction
or fail. Have the cooling system flushed and refilled
with Acura antifreeze/coolant as soon as possible.

Do not add rust inhibitors or other additives to your
vehicle’s cooling system. They may not be compatible
with the coolant or with the engine components.

WARNING

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.

Using a transmission fluid other than Acura ATF
DW-1 may adversely affect the operation and
durability of your vehicle’s transmission, and damage
the transmission.
Any damage caused by using a transmission fluid that
is not equivalent to Acura ATF DW-1 is not covered
by Acura’s new vehicle limited warranty.

Brake Fluid

NOTICE

Brake fluid marked DOT 5 is not compatible with your
vehicle’s braking system and can cause extensive
damage.

If the specified brake fluid is not available, you should
use only DOT 3 or DOT 4 fluid from a sealed
container as a temporary replacement.

Using any non-Acura brake fluid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and refilled with Acura Heavy
Duty Brake Fluid DOT 3 as soon as possible.

If the brake fluid level is at or below the
