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

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.

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.

Exterior CareDust off the vehicle body after you drive.
Regularly inspect your vehicle for scratches on painted surfaces. A scratch on a
painted surface can result in body rust. If you find a scratch, promptly repair it.
Wash the vehicle regularly. Wash more frequently when driving in the following
conditions:
•If driving on roads with road salt.
•If driving in coastal areas.
•If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
Fold in the door mirrors. Make sure to follow the instructions indicated on the
automated vehicle wash.
•Keep sufficient distance between the cleaning nozzle and the vehicle body.
•Take particular care around the windows. Standing too close may cause water to
enter the vehicle interior. Do not spray water into the engine compartment.■

274Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Promptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. Use a sponge and mild detergent to wipe away promptly.
Be careful not to use harsh chemicals (including some commercial wheel cleaners) or
a stiff brush. They can damage the clear coat of the aluminum alloy wheels that
helps keep the aluminum from corroding and tarnishing.■
