SPORT+ mode optimizes dynamic response
from all powertrain an d chassis systems -
perfect for your favorite winding road. • EV operation is elimin ated while operating
in SPORT+ .
TRACK mode gives maximum, consistent
performance from dyna mic systems during
track day lapping sessions. Hybrid battery
charge is maintained for consistent performance. • VSA ® OFF indicator is illuminated in TRACK
mode indicating reduced stability control.
This allows more body side slip and wheel
spin before VSA ® begins to operate.
• Integrated Dynamics switch must be turned
and held to the right for several seconds to
engage TRACK mode.

Cruise Control
Maintains a constant vehicle speed without having to keep your foot on the
accelerator. Use cruise control on freeways or open roads where you can travel at a
constant speed with little ac celeration or deceleration.
1Cruise Control It may not be possible to maintain a constant speed
when driving uphill or downhill.
When not using cruise control:
Turn off cruise control by pressing the CRUISE
button.
3WARNING
Improper use of the cruise control can lead
to a crash.
Use cruise control only when traveling on
open highways in good weather.When to use
■ Gear positions for cruise control:
In D (Drive) or M (Manual) Always keep sufficient distance
between you and the vehicle in
front of you.
■
Vehicle speed for cruise control:
Desired speed in a range above
roughly 25 mph (40 km/h) ~

Driving
Vehicle Stability Assist TM
(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 system . You will also see
the indicator blink.
■VSA ® Operation
1Vehicle Stability Assist TM
(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. 413
When the VSA ® system indicator comes on and stays
on while driving, there ma y 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 en tire 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.

This button is on the driver side control panel.
This button is used to change VSA ® modes.
See below for more information. VSA ® is turned on every time you turn the
power system on, even if you press the button
the last time you drove the vehicle.
■ When the Integrated Dynamics Syst em mode is in QUIET mode, SPORT
mode, or SPORT+ mode To enter Stuck Vehicle Assist mode, press
the VSA ® OFF button until a single beep is
heard and the VSA ® OFF indicator illuminates.
uThis message appears on the driver
information interface for a few seconds.
If the Integrated Dyna mics System mode is
changed, VSA ® will remain in Stuck Vehicle
Assist mode.
To exit Stuck Vehicle Assist mode, press the
VSA ® OFF button until a single beep is heard
and the VSA ® OFF indicator extinguishes.
■VSA ® On and Off1Vehicle Stability Assist TM
(VSA ®), aka Electronic Stability Control
(ESC), System
In Stuck Vehicle Assist mode, your vehicle will have
normal braking and corn ering ability, but VSA®
traction and stability enhancement becomes less
effective.
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with Stuck Vehicle Assist mode.
In Stuck Vehicle Assist mode, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the button
pressed if you are not ab le to free it without.
Immediately after freeing your vehicle, be sure to
press the button again. We do not recommend driving your vehicle with Stuck Vehicle Assist mode.
You may hear a motor sound coming from the front
of the vehicle while system checks are being
performed immediately after turning the power
system on or while driving. This is normal.VSA ® OFF Indicator

The system controls and transfers varying amounts of motor and/or engine torque
to each wheel in accordance with the driving conditions.
SPORT HYBRID SH-AWD ® helps to enhance driving stability, and lets you handle
situations like slippery surf aces better than when drivi ng with standard two wheel
drive. However, the system does not help to enhance braking. Be cautious about the
following:• It is still your responsibility to drive sa fely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.1SPORT HYBRID Super Handling All-Wheel-Drive TM

uuWhen DrivinguTire Pressure Monitoring System (TPMS)
Driving
To select the tire pressure monitor, set the
power mode to ON, and roll the right selector
wheel until you see the tire pressure screen.
The pressure for each tire is displayed in PSI
(U.S.) or kPa (Canada).
Tire Pressures Low is displayed when a tire
has significantly low pressure. The specific tire
is displayed on the screen.
Tire Pressure Too Low For High Speed
Driving is displayed when driving at an
extremely high speed and one or more tires
are underinflated.
uDecelerate and drive your vehicle until
the message disappears.
■Tire Pressure Monitor1Tire Pressure Monitor The pressure displayed on the driver information
interface can be slightly different from the actual
pressure as measured by a gauge. If there is a significant di fference between the two values, or if
the low tire pressure/TPMS indicator and the message
on the driver information in terface do not go off after
you have inflated the tire to the specified pressure,
have the system checked by an authorized Acura NSX
dealer.
Tire Pressure Monitor Problem may appear on the
driver information interface if there is a problem with
the TPMS. Please have the system checked by an
authorized Acura NSX dealer.

uuWhen DrivinguTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumination of th e TPMS low tire pressure telltale.
Your vehicle has also been equi pped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the syst em detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illumina ted. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

The power mode must be in the ON position
to release the electric parking brake. 1. Depress the brake pedal.
2. Press the electric parking brake switch.
uThe parking brake indicator goes off.
Manually releasing the parking brake using
the switch helps your vehicle start slowly and
smoothly when facing downhill on steep hills.
■Parking Brake1Brake System
When you depress the brak e pedal, you may hear a
whirring sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.

apply or release the parking brake.
You cannot apply or release the parking brake if the
12-volt battery goes dead.
2 Jump Starting P. 448
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the electric servo brake
system until the vehicle comes to a stop. The
electric parking brake then applies, and the
switch should be released .
