Document Purpose
The purpose of this document is to familiarize emergency responders and the towing/roadside
assistance industry with the proper methods to handle the Hyundai Sonata Plug-in Hybrid in an
emergency situation. This guide offers a basic overview of key vehicle systems and provides
instructions for dealing with the different types of situations encountered by emergency
responders. The emergency response procedures for this vehicle are somewhat similar to a
conventional Sonata with additional information provided on dealing with the high-voltage
electrical system.
Vehicle Description
As with other plug-in hybrids, the Hyundai Sonata Plug-in Hybrid uses a conventional gasoline
powered internal combustion engine paired with a high-voltage electric motor to propel the
vehicle. The high-voltage battery is recharged by an external power source such as a charging
station through charging port. It is also recharged while the vehicle is being driven. This is
accomplished through the use of a generator that produces electricity during driving and braking.
