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.

Keyless Access Remote Battery Strength
If the battery life in your keyless access remote is weak, a
message appears in the driver information interface with
information on how to start the engine.
Touch the back of the keyless access remote to the ENGINE
START/STOP button while the indicator is flashing.
With the brake pedal pressed, press the ENGINE START/STOP
button within 10 seconds.
Emergency Power System Off
The ENGINE START/STOP button may be used to turn off the power system due to an
emergency situation even while driving. If you must turn off the power system, choose one of
the following operations:
Press and hold the ENGINE START/STOP button for two seconds,
OR
Firmly press the ENGINE START/STOP button three times.
Turning off the engine disables the power assist to the steering and braking systems. Thus,
it will require significantly more physical effort and time to steer and slow the vehicle.
Downshift gears and use both feet on the brake pedal, if necessary, to slow the vehicle and stop
immediately in a safe place.
Once the vehicle comes to a complete stop, the gear position automatically changes to (P) and
the power mode changes to VEHICLE OFF.
Do not press the button while driving unless it is absolutely necessary for the engine to be
switched off.

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
