DRIVINGDRIVING
n While Driving
•
You may see a brake warning message in
the Driver
Information Interface (and warning message chime) and/
or experience increased brake pedal stroke. If either occurs,
immediately slow down and allow for increased stopping
distances. The message will disappear once the brakes have
cooled and the system has returned to normal operating
condition.
• After high-performance driving, it is critical to allow your vehicle to properly cool down.
Do not immediately stop your vehicle. Instead, continue driving at reduced speeds,
allowing for increased braking distances until your vehicle returns to normal operating
temperatures. Once you stop and safely park the NSX, open the hatch to aid cooling. If
the engine oil temperature reaches the H mark during high-performance driving, have
your NSX inspected by an authorized Acura NSX dealer.
n
AFTER DRIVING
Check your NSX, and each of its r

elevant components, to make sure that it still is in a safe
operating condition (example: wheel lug bolt torque, tire pressure, etc.). We recommend
you repeat the Before Driving protocol. If any item shows excessive wear or appears to be
in an unusual condition, have it replaced, or exercise appropriate caution when driving and
see your authorized Acura NSX dealer
For more information, please contact your authorized Acura NSX dealer, and/or Acura Client
Relations (see page 213).
Cold or Rainy Weather Driving
Summer-only and Ultra High Performance (UHP) tires are very sensitive to ambient
temperatures and are designed to be used at temperatures above 45°F (7°C). Below that
temperature, Summer-only and UHP tires provide decreasing amounts of grip and other
performance attributes. At temperatures below -4°F (-20°C), the tire treads may become
brittle, resulting in permanent damage to the tread. A damaged tire may fail during use.
Therefore, if you will operate the vehicle when temperatures are below 45°F (7°C), we
recommend you install other tires (e.g., mud+snow, winter) designed to perform under the
expected conditions.
Use of Summer-only or Ultra High Performance tires at temperatures below 45°F
(7°C) may lead to a loss of performance and control, which could result in a crash,
serious injury or death.
WARNING
Your NSX is equipped with ultra-high-performance summer-only tires that, due to their
decreased tread depth, are at greater risk of hydroplaning on wet roads compared to regular
tires. Exercise caution when driving on wet surfaces.

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.

n Inspecting and Changing Fuses
Set the power mode to
VEHICLE OFF (LOCK). Turn off the
headlights and all accessories.
Remove the fuse box cover.
Check the large fuse in the hood.
If the fuse is blown, use a Phillips-head screwdriver to remove
the screws and replace the fuse with a new one. Reinstall the
screws.
Inspect the small fuses in the hood and the vehicle interior.
If there is a burned out fuse, remove it with the fuse puller and
replace it with a new one.
Blown fuse
Combined fuse
Fuse puller
Replacing a fuse with one that has a higher rating greatly increases the chances of damaging
the electrical system.

Never leave rags, towels, or other flammable objects in the engine compartment.
To clean parts, use a commercially available degreaser or parts cleaner, not gasoline.
Wear eye protection and protective clothing when working with the battery or compressed
air.
Do not run the engine in confined spaces where carbon monoxide gas can accumulate.
n
Vehicle Safety
The vehicle must be stationary

, and parked on level ground with the parking brake set and
the engine off.

n 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 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.
Select All Items Due, then press the wheel. The maintenance items disappear, and the
engine oil life display returns to 100%.
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.
NOTICE
Engine Coolant
Park the vehicle on level ground. Check the reserve tank and the coolant level in the radiator.
We specify Acura Long Life Antifreeze/Coolant Type 2.
n
Checking the Coolant Lev

el
Open the hatch and remove the driver’s side engine cover (see
page 183).
If the coolant level in the reserve tank is below the MIN mark,
add the specified coolant until it reaches the MAX mark.
Inspect the cooling system for leaks.
Reserve Tank MAXMIN
If temperatures consistently below −22°F (−30°C) are expected, the coolant mixture should
be changed to a higher concentration. Consult your authorized Acura NSX dealer for more
information.
