SPORT HYBRID Super Handling All-Wheel- DriveTM
(SPORT HYBRID SH-AWD ®)
Your SPORT HYBRID SH-AWD ® vehicle uses a Twin Motor Unit, Direct Drive Motor, and a gasoline engine as propulsion sources, with electric
motors receiving electricity from an internal High Voltage battery.

Quick Reference Guide
Energy Efficiency
As with a gasoline-powered vehicle, hybrid vehicle fuel efficiency and driving range is most impacted by your driving style. Ag gressive
acceleration and high-speed driving can easily trigger the system to switch the propulsion source to the gasoline-powered engin e.
In addition, heavy climate control system us e negatively affects vehicle range and efficiency. Either of these use patterns wil l more quickly
reduce the High Voltage battery's state of charge.
Battery Types
There are two types of batteries used in this vehicle; a standa rd 12-volt battery that powers the airbags, the interior and exterior lights, and
other standard 12-volt systems; and a High Voltage battery that is used to power the propulsion motors and recharge the 12-volt battery.
Regenerative Energy and Regenerative Braking
When decelerating without the accelerator being depressed or the brake pedal being applied, or while driving downhill, the elec tric motors
act as generators that a portion of the elec trical energy that was used to accelerate the vehicle. This regenerative braking slows the vehicle
in a manner similar to engine braking in a gasoline-powered vehicle.

Quick Reference Guide
Auto Engine Stop/Start
Your vehicle’s gasoline engine will automatically stop and start during vehicle operation as needed to meet driving and battery conditions.
These are some examples that could cause the gasoline engine to automatically start.
In the following cases, however, Auto Engine Stop may not activate. ● When the Integrated Dynamics System is in SPORT+ mode or TRACK mode.
● The vehicle momentarily needs additional power for aggressive acceleration, or driving uphill or at high speed.
● The climate control system is in heavy use.
● The High Voltage battery temperature is high or low.
● The High Voltage battery state of charge is low.
● The engine coolant temperature is low.
● When the door is opened after releasing seatbelt.
● When the shift position is in M (Manual) mode.

Quick Reference Guide
Safety PrecautionsDo not touch the High Voltage system
Attempting to take a High Voltage system component apart or disconnect one of its wires
can cause severe electrical shock. If the High Voltage system needs maintenance or repair, it
should be performed at an authorized Acura NSX dealer.
If a crash occurs ● Be careful of electric shock hazard.
uIf a severe crash damages your vehi cle’s High Voltage system, there is a possibility of electrical shock
due to exposed High Voltage components or wires. If this happens, do not touch any of the High
Voltage system components or any of its orange wires. ● Avoid contact with High Voltage battery fluid.
uThe High Voltage battery contains a flammable electrolyte that could leak as a result of a severe
crash. Avoid any skin or ey e contact with the electrolyte as it is corrosive. If you accidentally touch it,
flush your eyes or skin with a large quantity of water for at le ast five minutes, and seek medical
attention immediately. ● Use a fire extinguisher for an electrical fire.
uAttempting to extinguish an electrical fire with even a small quantity of water, from a garden hose
for instance, can be dangerous. ● Anytime the vehicle is damaged in a crash, have it repaired by an authorized Acura NSX
dealer.
Emergency Shutdown System for the High Voltage System
The emergency shutdown system may activate when the vehicle is impacted by some
incident such as a crash. When this system activates, the High Voltage system automatically
shuts down, and your vehicle no longer will move under its own power. To return the High
Voltage system back to normal operation, consult an authorized Acura NSX dealer.
Acura collects and recycles High Voltage batteries used in its vehicles – consult an
authorized Acura NSX dealer for more information.

after several seconds if the power
system did not turn on. If
“readiness codes” have not been
set, it blinks five times before it goes off.
• Comes on if there is a problem
with the emissions control system.
• Blinks when a misfire in the
engine’s cylinders is detected.• Readiness codes are part of the on board
diagnostics for the emissions control
systems.
2Testing of Readiness Codes P. 473
• Comes on while driving - Have your
vehicle checked by an authorized Acura
NSX dealer.
• Blinks while driving - Stop in a safe
place where there are no flammable
objects. Stop the power system for 10
minutes or more, and wait for it to cool
