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.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■Reserve Tank
1Engine CoolantNOTICEIf temperatures consistently below -22°F (-30°C) are
expected, the coolant mixture should be changed to
a higher concentration. Consult a dealer for more
information.
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.

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.

Maintenance
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 car 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.■Washing the Vehicle■Using an Automated Car Wash■Using High Pressure Cleaners

Maintenance
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.■Applying Wax■Maintaining the Bumpers and Other Resin Coated Parts■Cleaning the Window■Maintaining Aluminum Wheels
1Applying WaxNOTICEChemical solvents and strong cleaners can damage
the paint, metal, and plastic on your vehicle. Wipe up
spills immediately.1Maintaining the Bumpers and Other Resin Coated Parts
Ask a dealer about the correct coating material when
you want to repair the painted surface of the parts
made of resin.1Cleaning the Window
Wires are mounted to the inside of the rear window.
Wipe along the same direction as the wires with a
soft cloth so as not to damage them.
