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 IONIQ 5 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 system.
Vehicle Description
An electric vehicle is driven using a battery and an electric motor. While general vehicles use an
internal combustion engine and gasoline as fuel, electric vehicles use electrical energy that is
charged inside the high voltage battery. As a result, electric vehicles are eco-friendly in that they
do not require fuel and do not emit exhaust gases.
When decelerating or driving downhill, regenerative braking is utilized to charge the high voltage
battery. This minimizes energy loss and increases the range of the vehicle.
When the battery charge is not sufficient, normal charge, quick charge and trickle charge are
available.

IONIQ 5 Identification 2
General Vehicle Description
The Hyundai IONIQ 5 is very similar to the existing five-door hatchback, but there are some
notable exceptions. Using the information provided in this section, responders will be able to
differentiate between the two.
Charging Port
The Charging Port is located on the side outer panel covered by the charging port cap and it has
one port for AC normal, fast and trickle charging.
How to open the charging port
1. Depress the brake pedal and apply the
parking brake.
2. Turn OFF all switches, shift to P (Park), and
turn OFF the vehicle.
3. Push the charging door where the icon is
located to open. The charge door opens only
when the door is unlocked until 2 minutes
after turn OFF.
4. Remove the charging inlet cover ①.
Identifying a Hyundai electric vehicle
Vehicle Underside
An orange-colored cable covered by the under cover is
also visible on the underside of the vehicle.
Open the Charging port in Emergency
1. Put your finger between the charge door and
the vehicle body.
2. Lift the charge door Panel
※ Please use only during discharge and failure

IONIQ 5 main systems 5
High-Voltage Electrical Isolation
Unlike the 12V electrical system that is grounded to the vehicle’s chassis, the IONIQ 5’s high-
voltage electrical system is designed to be isolated from the vehicle.
Regulation of High-Voltage Electrical Current
The Power Relay Assembly (PRA) is mounted
rear side of the High-Voltage Battery Pack
Assembly and controls the high-voltage
power circuit between the High-Voltage
Battery and the Electric Power Control Unit.
High-Voltage Safety System
There are multiple safety systems
incorporated into the IONIQ 5. The system
that protects the High-Voltage Electrical
System is called the Battery Management
Unit (BMU). The BMU is located beside the
Power Relay Assembly and measures several
parameters to maintain the optimal
performance of the High-Voltage Battery. In
addition, if a system fault occurs, the BMU
turns off the PRA to protect the system.
PRA
BMU
•Never cut or disconnect the high voltage orange cabling and connectors without first disabling
the system by removing the High voltage cut-off Switch.
•Exposed cables or wires may be visible inside or outside the vehicle. Never touch the wires,
cables, connecters, or any electric components before disabling the system, to prevent injury or
death due to electrical shock.
Failure to follow these instructions can lead to death by electrical shock.
Electrocution Risk!

Airbag system (SRS : Supplemental Restraint System)
1. Driver’s front airbag
2. Passenger’s front airbag
3. Seat Belt Pretensioner (BPT)
4. Side Airbag (Driver, Passenger, Center)
5. Curtain Airbag (Driver, Passenger side)
6. Supplemental Restraint System Control Module
(SRSCM)
•Do not cut through any component.
•SRS components may remain powered and active for up to 3 minutes after the 12V electrical
system is shut off or disabled. Disconnect the battery negative cable and wait for at least 3 minutes
before beginning work.
Failure to follow any of these instructions may result in serious injury or death from accidental
deployment of the airbag system.

Emergency procedures
Initial Response:
The following procedures should be used whenever you are dealing with a IONIQ 5 at an
emergency scene. All other operations should be consistent with your department’s standard
operating procedures or guides. Electric vehicles damaged by a crash may have compromised
high voltage safety systems and present a potential high voltage electrical shock hazard. Exercise
caution and wear appropriate personal protective equipment (PPE) safety gear, including high
voltage safety gloves and boots. Remove all metallic jewelry, including watches and rings.
Identify
When dealing with a IONIQ 5 at the scene of an accident, emergency responders should always
assume that it is a electric model until it can be proven otherwise using the identification features
outlined in this ERG. Always be sure to inspect multiple sides of the vehicle as well as using the
clues found under the hood and in the interior of the vehicle.

Emergency procedures
Immobilize
The next step is to immobilize the vehicle to prevent any accidental movement that can endanger
the emergency response personnel and any crash victims. Since the IONIQ 5 doesn’t have an
engine, there will be instances where the vehicle appears to be off because of the absence of
engine noise. When in its “ready” mode, the vehicle can move almost silently using the electric
motor. Responders should approach the vehicle from the sides and stay away from the front or
rear as they are both potential paths of travel. Instructions for immobilizing the vehicle are shown
below.
