SPORT HYBRID Super Handling All-Wheel-
Drive
TM (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. Aggressive
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 electric 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.
About Your Vehicle’s Limited Operating Temperature
If the outside temperature is about -4°F (-20°C), some operation might be limited.
The limited operation is listed below:
2 High Voltage Battery (P94)
2 Dual Clutch Transmission (P329)
2 Shifting (P330)
Sounds Unique to th e SPORT HYBRID SH-AWD ® System
When you first start driving this vehicle, you likely will hear some unfamiliar sounds, particular ly when you first turn on the power system,
while driving, and just after parking. Some of these sounds are unique to this ve hicle‘s powertrain, fuel, and climate control systems; others
are similar to sounds generated by conventional automobiles that typically are masked by louder noises absent from a vehicle of this design.
These sounds are not a cause for concern, and you will soon recognize them as normal and thus be able to detect any new or unus ual noise
should one develop.
About a system to cool the High Voltage battery using the climate control system.●The system will not be activated when the defroster is ON.●When the outside temperature is in extreme hot or cold condit ion, the system may not provide sufficient cooling performance to the
High Voltage battery due to the protection of the electric A/C compressor.
●When the system is active, the climate control system may not work sufficiently.

Safety Precautions
Do not touch the High Voltage systemAttempting 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 vehicle’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 SystemThe 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.
