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.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: Honda 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 coolant system. They may not be compatible
with the coolant or with the engine components.

Do not attempt to check or change the automatic transmission fluid yourself. The
location of the ATF dipstick and fill increases the likelihood that you could be burned
when trying to check or change the ATF.■

transmission fluids.
Using a transmission fluid other than Acura ATF
DW-1 may adversely affect the operation and

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.

the light assembly.
1Headlight Bulbs
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, have the aiming readjusted
at a dealer or by a qualified technician.
The exterior lights’ inside lenses (headlights, brake
lamps, etc.) may fog temporarily after a car wash or
while driving in the rain. This does not impact the
exterior light function.
However, if you see a large amount of water or ice
accumulated inside the lenses, have your vehicle
inspected by a dealer.
