Introduction - Hyundai NEXO Emergency Response Manual

Introduction

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 NEXO 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 vehicle, with additional
information provided on dealing with the high-voltage electrical and hydrogen system.
Vehicle Description
A hydrogen electric vehicle is a vehicle that generates electrical energy through a fuel cell system.
While regular vehicles use an internal combustion engine and gasoline as fuel, hydrogen electric
vehicles use electrical energy that is produced by the reaction of hydrogen and oxygen. As a result,
hydrogen electric vehicles are eco-friendly since they do not emit exhaust gases.
When decelerating or driving downhill, regenerative braking is utilized to charge the high voltage
battery. This minimizes energy losses and increases the range of the vehicle.
