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 the 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
1 Precautions While Driving
Do not press the
(N button, as you will lose
regenerative braking (and ac celeration) 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 ve hicle parked until the
READY indicator comes on.

Shifting
Change the gear position in acco rdance with your driving needs.
■Shift button positions
1Shifting
While the High Voltage battery charge level is full, or
the High Voltage battery temperature is low,
regenerative braking ma y become less effective.
To prevent malfunc tion and unintended
engagement:
•Do not spill any liquids on or around shift buttons.
•Do not place or drop any objects on or around shift
buttons.
•Do not let passenger or children operate the shift
buttons.
You may occasionally find th at it takes longer than
usual for the vehicle to start moving when you select
( R, release the brake peda l, and/or depress the
accelerator pedal. This may occur when the High
Voltage battery charge level is extremely low; in this
circumstance, it does not indicate a vehicle
malfunction.
3WARNING
The vehicle can roll aw ay if left unattended
without confirming that Park is engaged.
Always keep your foot on the brake pedal
until you have confirmed that
( P is shown
on the gear position indicator.
Park
Used when parking or starting the power
system
Reverse
Used when reversing
Neutral
Used to keep the transmission disengaged
from the engine and motor.
Drive/Manual
Each time you press the button, the
mode switches between D (drive) and M
(manual) mode.
Used for:
●Normal driving (gears change between 1st
and 9th automatically)

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 curren tly 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 tac hometer’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
the tachometer’s red zone.

If you open the driver’s door under the following conditions, the gear position
automatically changes to
(P.
• The vehicle is in stationary with the power mode in ON, or moving at 1 mph (2
km/h) or slower.
• The transmission is in other than
(P.
• You have unfastened the driver side seat belt.
u If you manually change the gear position from
(P with the brake pedal
depressed, the gear position will automatically return to
(P once you release
the brake pedal.
■When turning off the power mode
If you turn the power system off while the vehicle is stationary, and the transmission
is in other than
(P, the gear position automatically changes to (P.
■If you want to keep the transmission in (N position (car wash mode)
With the engine running:
1. Press and hold the brake pedal.
2. Press
(N. Within two seconds press and hold (N for two seconds.
3. Within five seconds press the ENGINE START/STOP button.
u This puts the vehicle in car wash mode which must be used when your vehicle
is pulled through a conveyor type automatic car wash where you or an

The vehicle will go into the sequential m ode momentarily, and the gear selection
indicator becomes more prominent.
The sequential mode is automatically canc eled and the gear selection indicator
returns to ordinary display under the following conditions.
• Hold the
(+ paddle shifter for a few seconds.
• Once you start traveling at a constant speed.
• The vehicle comes to a complete stop.
• When you change to another IDS mode.
The sequential mode automatically shifts under following condition
• Accelerator pedal depressed beyond the click.
• Engine speed reaches near the tachometer’s red zone.
• Engine speed reaches idle speed while deceleration.

■Sequential Mode Operation1Sequential Mode Operation
Each paddle shift operation makes a single gear
change.
To change gears continu ously, release the paddle
shifter before pulling it again for the next gear.
If the sequential mode gear selection indicator blinks
when you try to shift up or down, this means your
vehicle speed is not in its allowable gear range.
Slightly accelerate to shift up and decelerate to shift
down while the indi cator is blinking.
In Manual mode, to pr ioritize the engine
performance enhancement, the transmission may
not allow for shifting up while the engine speed is
low.
