uuBefore Driving uHigh-Performance Driving
Driving
High-performance driving requires special skills, knowledge and experience, as the
safety risks are greatly increased when the NSX is operated at its upper performance
abilities. As a responsible NSX driver, you should not drive above your skill limits or
training, even if the NSX’s performance le vels would otherwise allow you to do so.
If you intend to engage in high-perform ance driving, Acura strongly recommends
that:
• You first obtain appropriate, professional training
• Turn off any devices or systems that may distract you from the driving task
High-performance driving in general, and the use of TRACK mode and Launch
Control in particular, puts very high loads on the NSX and its components, and
results in greater wear and tear on the vehicl e. Because of these high loads, if your
NSX is not in top condition or if certain comp onents, such as the brakes or tires, have
undue wear, those components could experience a loss of performance, or fail,
when engaging in high-performance driv ing. Therefore, Acura highly recommends
that you undertake more proactive and fre quent maintenance than that required
under normal use and have your vehicle inspected at an authorized Acura NSX
dealer (and all necessary repairs or adju stments made) before you engage in any
high-performance driving. In addition to any required maintenance, there are
certain NSX specific items and protocols th at you should pay special attention to
before, during and after engaging in any high-performance 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.
BEFORE DRIVING
•With the vehicle parked on level gro und, properly bleed brake system after
replacing with Acura Heavy Duty Brake Fluid DOT 4 or equivalent
• Inspect brake pad thickness an d replace if 6.0 mm or less

uuWhen Driving uDual Clutch Transmission
Driving
If there is a strong impact with something under the vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks.
If any of these components are damaged or loose, the stability, handling, and
powertrain cooling performance of the vehicle may be adversely affected.
Dual Clutch Transmission
As with a conventional gasoline-powered ve hicle with an automatic transmission,
this vehicle will creep.
Keep the brake pedal firmly depressed when stopped.
The accelerator pedal features a kick down switch. Quickly depressing the
accelerator pedal while driving may cause th e transmission to drop to a lower gear,
subsequently increasing vehicle speed. De press the accelerator pedal carefully,
especially when driving uphill, on slippery roads, and curves.
■Other Precautions
■Creeping
■Kickdown
1Precautions While Driving
Do not select
(N while driving as you will lose engine
braking (and accelera tion) performance.
Avoid hard braking for the first 200 miles (300 km).
You should also follow this recommendation when
the brake pads are replaced.
Models with iron brake discs
1 Dual Clutch Transmission
The DCT will not operate when it is extremely cold. If
the vehicle has been parked in extremely cold
conditions, after you start th e engine, wait until it
gets warm. Keep your vehicle parked until the
READY indicator comes on.

Maintenance
Before Performing Maintenance
Inspection and Maintenance
For your safety, perform all listed inspections and maintenance to keep your vehicle
in good condition. If you become aware of an y abnormality (noise, smell, insufficient
brake fluid, oil residue on the ground, etc .), have your vehicle inspected by an
authorized Acura NSX dealer. (Note, however, that service at an authorized Acura
NSX dealer is not mandatory to keep your wa rranties in effect.) Refer to the separate
maintenance booklet for detailed maintenance and inspection information.
■Routine inspections
Perform inspections before long distance trips, when washing the vehicle, or when
refueling.
2 Maintenance P. 28
■Periodic inspections
• Check the brake fluid level monthly.
2 Brake Fluid P. 404
•Check the tire pressure monthly. Examin e the tread for wear and foreign objects.
2Checking and Maintaining Tires P. 411
•Check the operation of the exterior lights monthly.
2 Replacing Light Bulbs P. 405
•Check the condition of the wiper bl ades at least every six months.
2Checking and Maintaining Wiper Blades P. 408
■Types of Inspection and Maintenance
1Inspection and Maintenance
Maintenance, replacement, or repair of
emissions control devices and systems may be
done by any automotive repair establishment or
individuals using parts that are “certified” to
EPA standards.
According to state and fede ral regulations, failure to
perform maintenance on the maintenance main
items marked with # will not void your emissions
warranties. However, all ma intenance services should
be performed in accordan ce with the intervals
indicated by the driver information interface.
2 Maintenance Service Items P. 386
If you want to perform complex maintenance tasks
that require more skills a nd tools, you can purchase a
subscription to the Service Express website at
www.techinfo.acura.com .
2 Authorized Manuals P. 482
If you want to perform ma intenance yourself, make
sure that you have the necessary tools and skills first.
After performing maintenanc e, update the records in
the separate maintenance booklet.

u Make sure your vehicle is parked on leve l ground, the parking brake is set, and
the power system is turned off.
• Be aware that hot parts can burn you.
u Make sure to let the power system, including the engine an d exhaust system,
cool thoroughly before touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not activate the power system unle ss instructed, and keep your hands and
limbs away from moving parts. When the power system is on, the engine can
automatically start, or the radiator fan may start operating without the engine
running.
• Do not touch the high -voltage battery and wiring (orange).
Parts and Fluids Used in Maintenance Service
The use of Acura genuine parts and fluids is recommended when maintaining and
servicing your vehicle. Acura genuine parts are manufactured according to the same
high quality standards us ed in Acura vehicles.
