2023 HYUNDAI ELANTRA HYBRID electrical system

01
1-11
When the hybrid system is turned ON,
the gasoline engine may run or may not.
In this situation, you may feel a vibration.
This does not indicate a malfunction.
When the “
” indicator illuminates, the
hybrid system is ready to begin driving.
Even if the engine is off, you can operate
the vehicle as long as the “
” indicator
is illuminated.
NOTICE
The hybrid system contains many
electronic components. High voltage
components, such as cables and other
parts, may emit electromagnetic waves.
Even when the electromagnetic cover
blocks electromagnetic emissions,
electromagnetic waves may have an
effect on electronic devices. When your
vehicle is not used for a long period of
time, the hybrid system will discharge.
You need to drive the vehicle several
times a month. We recommend driving
at least for 1 hour or 10 miles. When the
hybrid battery is discharged, or when it
is impossible to jump start the vehicle,
we recommend that you contact your
authorized HYUNDAI dealer.
WARNING

[ When you start the hybrid system
with the shift lever in P (Parking),
the “
” indicator illuminates on
the instrument cluster. The driver
can drive the vehicle, even when the
gasoline engine is off.

[ When you leave the vehicle, you
should turn OFF the hybrid system
or locate the shift lever in P (Park).
When you depress the accelerator
pedal by mistake, or when the shift
lever is not in P (Park), the vehicle
will abruptly move, possibly resulting
in serious injury or death.
Virtual Engine Sound System (VESS)
The Virtual Engine Sound System
generates engine sound for pedestrians
to hear vehicle sound because there is
limited sound while motor power is used.

[If the gear shifts from P (Parking) after
start-up, the VESS sound is output.

[ When the gear is shifted to R
(Reverse), an additional warning
sound will be heard.
What does regenerative braking do?
It uses an electric motor when
decelerating and when braking. It
transforms kinetic energy to electrical
energy in order to charge the high
voltage battery.
Battery

[The vehicle is composed of a high
voltage battery that drives the motor
and air conditioner, and an integrated
12V lithium ion polymer battery with
the HEV battery that drives the lamps,
wipers, and audio system.

[ The integrated 12V battery is
automatically charged when the
vehicle is in the ready (
) mode.

WARNING

[Never clean the cooling duct of the
hybrid battery with a wet cloth. If
any water enters the cooling duct
of the hybrid battery, the hybrid
battery may cause an electric shock,
resulting in a serious damage, an
injury or death.

[ The hybrid battery is composed of
lithium-ion polymer. If the hybrid
battery is improperly handled, it is
dangerous to the environment. Also
it may cause electrical shock and
severe burns, resulting in a serious
injury or death.

[ Do not spill liquid over the cooling
duct of the hybrid battery. Doing
so is very dangerous. It may cause
electric shock or serious injury.

[ Do not cover the cooling duct with
objects.

[ Do not put any objects into the
cooling duct of the hybrid battery.
Doing so may cause loss of cooling
duct volume to the hybrid battery.
When the cooling duct is blocked
with any objects, immediately
contact your HYUNDAI dealer.

[ Never place a container of liquid on
or near the cooling duct. If the liquid
spills, the hybrid battery located in
the luggage compartment may be
damaged.

[ Secure all loads in the luggage
compartment to prevent them from
being tossed about before driving.
When a sharp or heavy load strike
with a strong impact or pierce the
interior luggage compartment
wall, the hybrid battery system
may be damaged, deteriorating its
performance.

[ Do not obstruct the cooling duct
with any other objects.
If an Accident Occurs
WARNING

[For your safety, do not touch the
high voltage cables, connectors
and package modules. High voltage
components are orange in color.

[ Exposed cables or wires may be
visible inside or outside of the
vehicle. Never touch the wires or
cables, because an electrical shock,
an injury, or death may occur.

[ Any gas or electrolyte leakage from
your vehicle is not only poisonous
but also flammable. Upon witnessing
any of these conditions, open the
windows, and remain a safe distance
from the vehicle out of the road.
Immediately call emergency services
or contact an authorized HYUNDAI
dealer and advise them that a hybrid
vehicle is involved.

[ When the vehicle is severely
damaged, remain a safe distance of
50 feet (15 meter) or more between
your vehicle and other vehicles/
flammables.

Foreword / Hybrid System Overview1-24
WARNING
If a fire occurs:

[ If a small scale fire occurs, use a fire
extinguisher (ABC, BC) that is meant
for electrical fires.
If it is impossible to extinguish
the fire in the early stage, remain
a safe distance from the vehicle
and immediately call your local
fire emergency responders. Also,
advise them that a hybrid vehicle is
involved.
If the fire spreads to the high voltage
battery, large amount of water is
needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.

[ Upon witnessing any sparks, gases,
flames, or fuel leakage of your
vehicle, immediately call emergency
services or contact an authorized
HYUNDAI dealer. Also, advise them
that a hybrid vehicle is involved.
WARNING
When a submersion in water occurs:
When your vehicle is flooded in water, a
high-voltage battery may cause shock
or fires. Thus, turn the hybrid system
OFF, take the key in your possession and
escape to a safe place. Never attempt
physical contact with your flooded
vehicle.
Immediately contact an authorized
HYUNDAI dealer and advise them that a
hybrid vehicle is involved.
When the Hybrid Vehicle Shuts
Off
When the high voltage battery or 12 volt
battery is discharged, or when the fuel
tank is empty, the hybrid system may
not operate while driving. When the
Hybrid system does not operate, do the
following:
1. Gradually reduce the vehicle speed.
Pull over your vehicle off the road in a
safe area.
2. Make sure the shift lever is in P (Park).
3. Turn ON the hazard warning flashers.
4. Turn OFF the vehicle, and try to start the hybrid system again, while
depressing the brake pedal and
turning on the ignition switch.
5. When the hybrid system still does not operate, refer to “If the 12 Volt Battery
Is Discharged” section in chapter 8.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to “If the 12 Volt Battery
Is Discharged” section in chapter
8. When the fuel level is low, do not
attempt to drive the vehicle only with
the battery power. The high voltage
battery may be discharged, and the
hybrid system will turn OFF.

Seats & Safety System3-42
SRS warning light
The SRS (Supplement Restraint System)
air bag w
arning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential malfunction with your
air bag system, which could include your
side and curtain air bags used for rollover
protection.
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident, increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:

[ The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is
in the ON position.

[ The light stays on after illuminating
for approximately three to six
seconds.

[ The light comes on while the vehicle
is in motion.

[ The light blinks when the engine is
running.
Have an authorized HYUNDAI dealer
inspect the SRS as soon as possible if
any of these conditions occur.
During a frontal collision, sensors will
detect the vehicle’s deceleration. If the
rate of deceleration is high enough, the
control unit will inflate the front air bags.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact
or rollover.
[
Air bags are activated (able to inflate
if necessary) when the Engine Start/
Stop button is in the ON position or
approximately within 3 minutes after
ignition off.

[ Air bags inflate in the event of certain
frontal or side collisions to help
protect the occupants from serious
physical injury.

[ Generally, air bags are designed to
inflate based upon the severity of
a collision, its direction, etc. These
two factors determine whether
the sensors produce an electronic
deployment/inflation signal.

[ The front air bags will completely
inflate and deflate in an instant. It is
virtually impossible for you to see the
air bags inflate during an accident. It is
much more likely that you will simply
see the deflated air bags hanging out
of their storage compartments after
the collision.

[ In addition to inflating in certain side
collisions, vehicles equipped with a
rollover sensor, side and curtain air
bags will inflate if the sensing system
detects a rollover.
When a rollover is detected, side and
curtain air bags will remain inflated
longer to help provide protection
from ejection, especially when used in
conjunction with the seat belts.

[ To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
to inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.

Seats & Safety System3-46
For example, if a child restraint of the
type specified in the regulations is on the
seat, the occupant classification sensor
can detect it and cause the air bag to
turn OFF.
Front passenger seat adult occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however, if the occupant
does not sit in the seat properly (for
example, by not sitting upright, by sitting
on the edge of the seat, or by otherwise
being out of position), this could cause
the sensor to turn the air bag OFF.
You will find the “PASSENGER AIR BAG
OFF” indicator on the overhead console.
This system detects the conditions 1-4
in the following table and activates or
deactivates the front passenger air bag
based on these conditions.
Always be sure that you and all vehicle
occupants are seated properly and
wearing the seat belt properly for the
most effective protection by the air bag
and the seat belt.
Never install a Child Restraint System in
the front passenger’s seat. If you should
install a CRS (Child Restraint System)
inevitably, use a forward-facing CRS with
3-point ALR safety seat belt and adjust
the front passenger’s seat as far to the
rear as possible. If the PASSENGER AIR
BAG “OFF” indicator is OFF after a CRS
(Child Restraint System) is equipped,
the front passenger’s airbag is operating
so you should install the CRS in the rear
seats of the vehicle immediately. The OCS may not function properly if the
passenger takes actions which can affect
the classification system. These include:

[
Failing to sit in an upright position.

[ Leaning against the door or center
console.

[ Sitting towards the sides of the front
of the seat.

[ Putting their legs on the dashboard or
resting them on other locations which
reduce the passenger weight on the
front seat.

[ Wearing the seat belt improperly.

[ Reclining the seatback.

[ Wearing a thick cloth like ski wear or
hip protection wear.

[ Putting an additional thick cushion on
the seat.

[ Putting electrical devices (for
example, notebook, satellite radio) on
the seat with inverter charging.
