Oil Check

We recommend that you check the engine oil level every time you refuel.
Park the vehicle on level ground.
Turn off the power system. You can check the oil level without the engine having
run beforehand. If the engine has been running, wait approximately three minutes
before you check the oil.

1. Remove the dipstick (orange loop).
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.

Oil Check

If the oil level is near or below the lower mark, slowly
add oil being careful not to overfill.

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

Cooling System

Main

tenan

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. Check the amount of coolant in the reserve

tank.

2. 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 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.
