HANDLING THE UNEXPECTEDHANDLING THE UNEXPECTED
Overheating
If the temperature gauge needle is at the H mark, the engine suddenly loses power, or steam or
spray comes out from under the hatch, your engine is overheating.
Immediately park the vehicle in a safe place. Turn off all accessories and turn on the hazard
warning lights. Change the gear position to (P).
If no steam or spray is present: Keep the power system on and open the hatch.
If steam or spray is present: Turn off the power system and wait until it subsides. Then, open
the hatch.
Check that the cooling fan is operating and turn the power system off once the temperature
gauge needle comes down. If the cooling fan is not operating, immediately turn the power
system off.
Once the engine has cooled down, inspect the coolant level and
check the cooling system components for leaks. If the coolant
level in the reserve tank is low, or no coolant is in the tank, check
that the radiator is cool. Cover the reserve tank cap with a heavy
cloth and open the cap. Add coolant until it reaches the MAX
mark, and put the cap back on.
Reserve TankMAXMIN
Once the engine has cooled sufficiently, turn the power system on and check the temperature
gauge. If the temperature needle has gone down, resume driving. If it has not gone down,
contact an authorized Acura NSX dealer for repairs.
Steam and spray from an overheated engine can seriously scald you.
Do not open the hatch if steam is coming out.
WARNING
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.
WARNING
Continuing to drive with the temperature gauge needle at the H mark may damage the engine.

If you change or
replace the vehicle’s engine oil yourself, you must reset the engine oil
life. Use the right selector wheel on the steering wheel to make selections in the driver
information interface.
Whee lRight Selector
Set the power mode to ON. Roll the wheel until the oil life displays in the driver information
interface.
Press the wheel for at least 10 seconds, until you enter reset mode.
