Resetting the Engine Oil Life
If you change or replace the vehicle's engine oil yourself, you must reset the
engine oil life. Use the Info (p/q) and SEL/RESET buttons on the steering wheel
to make selections in the multi-information display (MID).
1. Scroll to Vehicle Settings and select it.
2. Scroll to Maintenance Info and select it. The oil life
reset mode is displayed.
3. Select Reset. The maintenance items disappear and
the engine oil life display returns to 100%.
NOTICE
Failure to reset the engine oil life after a maintenance service results in the
system showing incorrect maintenance intervals, which can lead to serious
mechanical problems.

Engine Coolant

Park the vehicle on level ground. Check the reserve tank and the coolant level in the
radiator. We recommend Acura Long Life Antifreeze/Coolant Type 2.
Checking the Reserve Tank
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.
Adding Coolant
1. Make sure the engine and radiator are cool.
2. Turn the radiator cap counterclockwise and
relieve any pressure in the coolant system. Do
not push the cap down when turning.
3. Push down and turn the radiator cap
counterclockwise to remove it.
4. The coolant level should be up to the base of the
filler neck. Add coolant if it is low.
5. Put the radiator cap back on and tighten it fully.
6. Pour coolant into the reserve tank until it
reaches the MAX mark. Put the cap back on the
reserve tank.
Removing the radiator cap while the engine is hot can cause the coolant to
spray out, seriously scalding you.
Always let the engine and radiator cool down before removing the radiator
cap.
NOTICE
If temperatures consistently below −22°F (−30°C) are expected, the coolant
mixture should be changed to a higher concentration. Consult your dealer for
more information.
NOTICE
Pour the fluid slowly and carefully so you do not spill any. Clean up any spills
immediately; they can damage components in the engine compartment.
