DRIVINGDRIVING
driving. Ultimately, the decision whether to engage in high-performance driving is yours, and
depending on your NSX’s condition and prior usage, the items and protocols listed below may
or may not be sufficient to ensure a safe driving experience.
n
BEFORE DRIVING
•
With the vehicle park

ed on level ground, properly bleed brake system after replacing with
new Honda DOT 4 brake fluid or equivalent.
•
Inspect brake pad thickness and replace if 6.0mm

or less.
•
Burnish the brake pads so that

they have the performance characteristics necessary
to repeatedly and quickly slow the NSX when it is being operated at significantly high
speeds. (While the NSX’s brake pads are properly burnished for the demands expected in
ordinary day-to-day driving, high performance driving puts unique demands on the brake
system which require further burnishing.) A high performance burnish at the driving venue
prior to the first session of the day is highly recommended.
•
Inspect ALL cooling openings to confirm

they are open and free of debris such as leaves,
etc. Cooling openings include engine undercover ducts, heat resistance ducts, brake ducts,
radiators, and intercoolers.
•
Remove

Tire Repair Kit from the trunk, along with any other cargo area contents.
•
Check tire wear and

tire pressure, and make certain wheel lug bolts are properly torqued,
as driving at high speed puts additional strain on tires and wheels. Never use slick tires,
and do not use Summer Only tires and Ultra High Performance tires if temperatures will
be lower than 45°F (7°C).
•
If you anticipate sustained driving at speeds gr

eater than 168 mph/270 km/h, adjust the
cold tire pressure as shown on the driver door jamb warning label. This will help avoid heat
build-up and sudden tire failure.
If driving at high speeds (over 168mph/270km/h),
adjust cold tire pressure as show n below to avoid
ex cess heat buildup and sudden tire failur e.

Use of slick tires/racing slicks may subject the chassis and body components to
higher dynamic loads than they were designed for.
Higher than intended dynamic loads could result in component failure, loss of
control, and serious injury or death to you or others.
Do not install slick tires on the NSX.
WARNING
• Inspect all exhaust mounts for cracks or signs of
wear.
•
Inspect tailpipe active exhaust val
ves to ensure they are functioning correctly. You can
do this by cycling the IDS switch between SPORT and TRACK modes, while the engine is
idling.

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 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.
NOTICE

MAINTENANCEMAINTENANCE
n Adding Coolant
Make sure
the engine and radiator are cool.
Turn the reserve tank cap counterclockwise and relieve any
pressure in the coolant system. Do not push the cap down
when turning.
Push down and turn the cap counterclockwise to remove it.
Pour coolant into the reserve tank until it reaches the MAX
mark. Put the cap back on the reserve tank and tighten.
Reserve Tank
Cap
Removing the reserve tank 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 reserve tank
cap.
WARNING
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.
NOTICE
Inverter Coolant
Check the inverter coolant level every time you refuel
n
Checking the Inverter

Coolant Level
Open the hood.
If the inverter coolant is below the MIN level, have your
vehicle serviced at an authorized Acura NSX dealer.

Window Washer Fluid
If the washer fluid is low, a message will appear on the driver information interface. Do not
overfill the reservoir.
Do not use engine antifreeze or a vinegar/water solution in the windshield washer reservoir.
Antifreeze can damage your vehicle’s paint. A vinegar/water solution can damage the windshield
washer pump.
