Before Driving
Driving Preparation
Check the following items before you start driving.
• Make sure there are no obstructions on th e windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
vision while driving. If frozen solid , remove ice once it has softened.
u When removing ice from around the wheel s, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.
u Check air pressures, and check for damage and excessive wear.
2Checking and Maintaining Tires P. 411
•Make sure there are no people or ob jects behind or around the vehicle.
u There are blind spots from the inside.
• Check the front bumper duct s and side intercooler ducts for mud, leaves, and
road debris that could build up and prevent proper cooling performance.
■Exterior Checks1 Exterior Checks
NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable materials left und er the hatch, causing a
fire. If you’ve parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal.
Also check under the hatch for leftover flammable
materials after you or so meone else has performed
maintenance on your vehicle.

When Driving
Turning on the Power
1.Make sure the parkin g brake is applied.
u The electric parking brake indicator
comes on for 15 seconds when you pull
up the electric parking brake switch.
2. Depress the brake pedal.1Turning on the Power
Keep your foot firmly on the brake pedal when
starting the power system.
The engine is harder to st art in cold weather and in
thinner air found at altit udes above 8,000 feet (2,400
meters).
When turning on the power system in cold weather,
turn off all electrical accessories such as the lights,
climate control system, and rear defogger in order to
reduce 12-volt battery drain.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by an authorized Acura NSX dealer. There
may be a problem with the engine or exhaust system.

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.

■Shift Operation1Shift Operation
NOTICE
Before you change to (R and vice versa, come
to a complete stop and keep the brake pedal
depressed.
Operating the shift button before the vehicle has
come to a complete standstill may damage the
transmission.
Use the gear position indicator and the shift button
indicator to check the gear position before selecting
a shift button.
If the indicator of the currently selected gear position,
or all gear position in dicators, are blinking
simultaneously, there is a problem with the
transmission.
Avoid sudden acceleration and have the transmission
checked by an authorized Acura NSX dealer as soon
as possible.
The fuel supply may be cut of f if you drive at engine
speeds in or over the tachometer’s red zone (engine
speed limit). If this happe ns, you may experience a
slight jolt.
When the engine speed is increased while the
transmission is in

be cut off even without the engine speed entering

uuWhen Driving uVehicle Stability AssistTM (VSA ®), aka Electronic Stability Control (ESC), System
Driving
Vehicle Stability AssistTM (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine and motor output and selectively applying the
brakes.
When VSA® activates, you may notice that the
engine and motor do not respond to the
accelerator. You may also notice some noise
from the hydraulic brake sy stem. You will also
see the indicator blink.
■VSA ® Operation
1 Vehicle Stability AssistTM (VSA ®), aka Electronic Stability Control
(ESC), System
VSA ® may not function properly if tire type and size
are mixed. Make sure to use the same size and type
of tire, and the air pr essures as specified.
2 Tire and Wheel Replacement P. 417
When the VSA ® system indicator comes on and stays
on while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by an authorized
Acura NSX dealer immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stab ility Control (ESC). The
system also includes a traction control function.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, an d helps you retain steering control by
pumping the brakes rapidly, much faster than you can.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
You may hear an operating noise when the ABS is working. Depress the brake pedal
and keep holding the pedal firmly down. On dry pavement, you will need to press
on the brake pedal very hard before the ABS activates. However, you may feel the
ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have your
vehicle checked by an authorized Acura NSX dealer
immediately.
The ABS does not reduce the ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, such as gravel or
snow.
•When tire chains are installed.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while vehicle is
accelerates.
These sounds are normal to ABS systems and are no
cause for concern.
