Event Data Recorders
This vehicle is equipped with an event data recorder (EDR).
The main purpose of an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deployment or hitting a
road obstacle, data that will assist in understanding how a vehicle’s
systems performed. The EDR is designed to record data related
to vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or le ss. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were
buckled/fastened;
3WARNING
California Proposition 65 Warning
Operating, servicing and maintaining a
passenger vehicle or off-road vehicle can
expose you to chemical s including engine
exhaust, carbon monoxid e, phthalates, and
lead, which are known to the State of
California to cause canc er and birth defects or
other reproductive harm. To minimize
exposure, avoid breathing exhaust, do not
idle the engine except as necessary, service
your vehicle in a well-ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more
information go to

.
• How far (if at all) the driver was depressing the accelerator
and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the
circumstances in which crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-trivial crash situation
occurs; no data are recorded by the EDR under normal driving
conditions and no personal data (e.g., name, gender, age, and
crash location) are recorded. Howeve r, other parties, such as law
enforcement, could co mbine the EDR data with the type of
personally identifying data rout inely acquired during a crash
investigation.
To read data recorded by an ED R, special equipment is required,
and access to the vehicle or the EDR is needed. In addition to the
vehicle manufacturer, other parties, such as law enforcement, that
have the special equipment, can re ad the information if they have
access to the vehicle or the EDR.
The data belongs to the vehicle ow ner and may not be accessed by
anyone else except as legally requir ed or with the permission of the
vehicle owner.
Service Diagnostic Recorders
This vehicle is equipped with se rvice-related devices that record
information about powertrain perfo rmance. The data can be used
to verify emissions law requirem ents and/or help technicians
diagnose and solve service problems. It may also be combined with
data from other sources for res earch purposes, but it remains
confidential. Some diagnostic and maintenance information is
uploaded to Acura upon vehicle start up.

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 elec tric motors
act as generators that recovers a portion of the electrical 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.
When the high voltage battery is fully charged or its condition is affected by extreme temperatur es or other factors, regenerative braking
may not work.

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.
●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.
When in SPORT mode, Auto Engine Stop does not activate.
Sounds Unique to th e SPORT HYBRID SH-AWD ® System
When you first start driving this vehicle, you will likely hear some unfamiliar sounds, particularly when you turn on the power system, or
while you are driving or accelerating from a stop. Some of thes e sounds are unique to this vehicle‘s powertrain, fuel, and climate control
systems; others are similar to sounds generated by conventional automobile s 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.

Depressing the accelerator
pedal does not release the
parking brake
automatically. Why?●Fasten the driver’s seat belt.
●Check if the transmission is in (P or (N. If so, select any other
position.
Why does the gear position
automatically change to

when I open the driver's
door to check for parking
space lines when
reversing?
●Fasten the driver’s seat belt.
●Close the driver's door and manually change the gear
position.
2 When opening the driver’s door (P 390)
Unleaded gasoline with a
Pump Octane Number
(PON) of 91 or higher is
recommended.
Is it possible to use
unleaded gasoline with a
Pump Octane Number
(PON) of 87 or lower on
this vehicle?Unleaded gasoline with a Pump Octane Number (PON) of 91 or
higher is recommended.
Use of lower octane gasoline can cause occasional metallic
knocking noise in the engine and will result in decreased engine
performance.
Use of gasoline with a pump octane less than 87 can lead to
engine damage.
