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 assi st 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 less. 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;
• 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.

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.
