uuMaintenance Under the HooduEngine Coolant
Maintenance
Engine CoolantThis 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.Remove the right-side engine compartment
cover.
2Engine Compartment Covers P. 233
2.Check the amount of coolant in the reserve
tank.
3.If the coolant level is below the MIN mark,
add the specified coolant until it reaches
the MAX mark.
4.Inspect the cooling system for leaks.
Specified coolant: Honda Long Life Antifreeze/Coolant Type 2■
Reserve Tank
1Engine Coolant
NOTICEYou will need a more concentrated coolant if you are
driving in extremely cold temperature below −31°F
(−35°C). Consult your Acura dealer for details about
a suitable coolant mixture.
If Honda 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-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.
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.4-cylinder models

carefully remove the under cover.
3.Remove the transmission filler bolt and
washer. Carefully feel inside the bolt hole
with your fingers.
uCheck if the fluid level is up to the edge
of the bolt hole.
4.If the fluid level is not up to the edge of the
bolt hole, add Acura Manual Transmission
Fluid (MTF) until it runs out of the hole.
5.Put a new washer on the filler bolt, then

Manual Transmission Fluid
Specified fluid: Acura Manual Transmission Fluid (MTF)
1Manual Transmission Fluid
If Acura MTF is not available, you may use the API
certificated SAE 0W-20 or 5W-20 viscosity motor oil
as a temporary measure.
Replace with MTF as soon as possible. Motor oil does
not contain the proper additives for the transmission
and continued use can cause decreased shifting
performance and lead to transmission damage.

Checking the Brake Fluid
1Brake/Clutch Fluid
NOTICEBrake 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-Honda brake fluid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and refilled with Honda Heavy
Duty Brake Fluid DOT 3 as soon as possible.
If the brake fluid level is at or below the MIN mark,
have a dealer inspect for leaks or worn brake pads as
soon as possible.

High Beam Headlight
1Headlight Bulbs
NOTICEHalogen bulbs get very hot when lit.
Oil, perspiration, or a scratch on the glass can cause
the bulb to overheat and shatter.
The headlight aim is set by the factory, and does not
need to be adjusted. However, if you regularly carry
heavy items in the trunk or tow a trailer, have the
aiming readjusted at a dealer or by a qualified
technician.
The HB3 and H1 types are halogen bulbs.
When replacing a bulb, handle it by its base, and
protect the glass from contact with your skin or hard
objects. If you touch the glass, clean it with
denatured alcohol and a clean cloth.
