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.

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.

MAINTENANCEMAINTENANCE
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.

SPECIFICATIONSMAINTENANCE
• If possible, remove the vehicle from the garage or enclosed area, remove covering, and
periodically run the engine until it reaches full operating temperature (the cooling fan cycles
on and off twice). Preferably, do this once a month.
•
To maintain the High V

oltage battery, drive your vehicle for more than 30 minutes at least
once every three months.
If road conditions are not suitable or desirable for driving, the following alternate procedure can
be used to maintain the vehicle’s High Voltage battery if local laws permit idling:
1.
Remove

the vehicle from the garage or enclosed area to prevent carbon monoxide
accumulation.
2.
Depress the brake pedal and pr

ess the ENGINE START/STOP button as you normally would
to start the vehicle.
3.
Allow the vehicle

to run for 30 minutes. Time spent at idle stop still counts as part of this
30-minute run.
Paint Care
Your vehicle’s paint requires up to 60 days from the production date to fully cure. During this
time, avoid applying any wax or paint sealant-type products, as they could hinder the curing
process and affect the paint’s durability.
You may polish the paint during these 60 days if the polishes do not contain any wax or paint
sealant ingredients. Use only clean, high-quality microfiber towels or pads, as they are softer
material and have less chance of scratching the finish. It is absolutely necessary to keep the
microfiber towels or pads properly cleaned and maintained before using on your vehicle.
For more information, contact an authorized Acura NSX dealer. n
