[Natural degradation may occur with
the high voltage battery depending
on the number of years the vehicle is
used. This may reduce the distance to
empty.

[When the charge capacity and
distance to empty keep falling,
contact a retailer of Genesis
Branded products for inspection and
maintenance.

[If the vehicle will not be in use for an
extended period of time, charge the
high voltage battery once every three
months to prevent it from discharging.
Also, if the charge amount is not
enough, immediately charge to full
and store the vehicle.

[AC charge is recommended to keep
the high voltage battery in optimal
condition.
If the high voltage battery charge
amount is below 20%, you can keep
the high voltage battery performance
in optimal condition if you charge the
high voltage battery to 100%. (Once a
month or more is recommended.)
The value of the high voltage battery
charge level may vary according to
the charging conditions (state of
charger, outside temperature, battery
temperature, etc.). In order to fully
charge the battery, the current of the
high voltage battery will be gradually
decreased, so that the longevity and
safety of the battery can be secured. CAUTION

[If the vehicle is kept with insufficient
charge for a long period, it may
damage the high voltage battery and
the high voltage battery may have to
be replaced depending on the level
of degradation.

[If the vehicle is in a collision, contact
a retailer of Genesis Branded
products to inspect whether the high
voltage battery is still connected.

[Using the V2L function may reduce
the driving distance due to the use
of high voltage battery energy, and
repeated use of the V2L function may
cause a decrease in the life of the
high voltage battery.

[Frequent DC charge can cause
reduced battery life.
High Voltage Battery Warmer
System
The high voltage battery warmer system
prevents reduction of battery output
when battery temperature is low. If the
charging connector is connected, the
warmer system automatically operates
according to the battery temperature.
Charging time may shorten compare to
vehicles without the high voltage battery
warmer system. But, electricity charge
may increase because of high voltage
battery warmer system operation.
CAUTION
The high voltage battery warmer
system operates when the charging
connector is connected to the vehicle.
However, the high voltage warmer
system may not operate when battery
temperature drops below -31°F (-35°C).

poles, etc.) not able to fit properly in the
trunk when closed.
1. Pull the armrest down.
2. Pull the cover down while pushing the
release lever down.
NOTICE

[Be careful when loading cargo
through the rear passenger seats
to prevent damage to the vehicle
interior.

[When both the armrest and the
panel are folded down, put back the
panel first, before folding back the
armrest. If not, the panel knobs and
the armrest knobs may interfere with
each other and get damaged.
CAUTION

[Make sure the vehicle is off, the
vehicle is shifted to P (Park) and the
parking brake is applied whenever
loading or unloading cargo. The
vehicle may move if the shift lever
is inadvertently moved to another
position.

[When cargo is loaded through the
rear passenger seats, ensure the
cargo is properly secured to prevent
it from moving while driving.
WARNING
Cargo should always be secured to
prevent it from being thrown about the
vehicle in a collision and causing injury
to the vehicle occupants. Do not place
objects in the rear seats, since they
cannot be properly secured and may hit
the front seat occupants in a collision.

SEAT BELTS
This section describes how to use the
seat belts properly. It also describes
some of the things not to do when using
seat belts.
Seat Belt Safety Precautions
Always fasten your seat belt and make
sure all passengers have fastened their
seat belts before starting any trip. Air
bags are designed to supplement the
seat belt as an additional safety device,
and are not a replacement. Most states
require all occupants of a vehicle to wear
seat belts.
WARNING
Seat belts must be used by ALL
passengers whenever the vehicle is
moving. Take the following precautions
when adjusting and wearing seat belts:

[Children under the age of 13 should
be properly restrained in the rear
seats.

ôNEVER allow children to ride in the
front passenger seat, unless the air
bag is deactivated. If a child is seated
in the front passenger seat, move the
seat as far back as possible. And the
child must always be restrained in
the seat properly.

[NEVER allow an infant or child to be
carried on an occupant’s lap.

[NEVER ride with the seatback
reclined when the vehicle is moving.

[Do not allow children to share a seat
or seat belt.

[Do not wear the shoulder belt under
your arm or behind your back.
[NEVER wear a seat belt over fragile
objects. If there is a sudden stop or
impact, the seat belt can damage it.

[Do not use the seat belt if it is
twisted. A twisted seat belt will not
protect you properly in an accident.

[Do not use a seat belt if the webbing
or hardware is damaged.

[Do not latch the seat belt into the
buckles of other seats.

[NEVER unfasten the seat belt
while driving. This may cause loss
of vehicle control resulting in an
accident.

[Make sure there is nothing in the
buckle interfering with the seat
belt latch mechanism, because any
materials in the buckle can cause the
seat belt not to be fastened securely.

[No modifications or additions
should be made by the user which
will either prohibit the seat belt
adjusting devices from operating to
remove slack, or prohibit the seat
belt assembly from being adjusted to
remove slack.
WARNING
Damaged seat belts and seat belt
assemblies will not operate properly.
Always replace:

[Frayed, contaminated, or damaged
webbing.

[Damaged hardware.

[The entire seat belt assembly after it
has been worn in an accident, even
if damage to webbing or assembly is
not apparent.

Rear center seatbelt (if equipped)
ORG3EV031037
1. Take out the buckle (2), which is
stored between the seat/seatback
cushions.
2. Insert the metal plate (1) into the
buckle (2), until it clicks.
You can make sure its secure
fastening by pulling the seatbelt
webbing. The buckle with ‘CENTER’
mark should be used for the 3-point
seatbelt.
3. Restore the buckle between the seat/
seatback cushion after unfastening
the seatbelt.
Pre-tensioner seat belt
ORG3EV031111N
Your vehicle is equipped with driver’s
and front passenger’s Pre-tensioner
Seat Belts(Retractor Pretensioner). The
purpose of the pre-tensioner is to make
sure the seat belts fit tightly against the
occupant’s body in certain frontal or side
collision(s).
When the vehicle stops suddenly, or
if the occupant tries to lean forward
too quickly, the seat belt retractor will
lock into position. In certain frontal or
side collision(s), the pre-tensioner will
activate and pull the seat belt into tighter
contact against the occupant’s body.
If the system senses excessive tension
on the driver or passenger’s seat belt
when the pre-tensioner system activates,
the load limiter inside the retractor
pre-tensioner will release some of the
pressure on the affected seat belt.

WARNING
ALWAYS properly restrain infants and
small children in a Child Restraint
System appropriate for the child’s
height and weight.
To reduce the risk of serious injury or
death to a child and other passengers,
NEVER hold a child in your lap or arms
when the vehicle is moving. The violent
forces created during an accident will
tear the child from your arms and throw
the child against the interior of the
vehicle.
Small children are best protected
from injury in an accident when
properly restrained in the rear seat
by a child restraint system that meets
the requirements of the Federal Motor
Vehicle Safety Standards. Before buying
any child restraint system, make sure
that it has a label certifying that it meets
Federal Motor Vehicle Safety Standard
FMVSS 213. The restraint must be
appropriate for your child’s height and
weight. Check the label on the child
restraint for this information. Refer to the
“Child Restraint Systems” section in this
chapter.
Larger children
Children under age 13 and who are
too large for a booster seat should
always occupy the rear seat and use the
available lap/shoulder belts. A seat belt
should lie across the upper thighs and
be snug across the shoulder and chest
to restrain the child safely. Check belt fit
periodically. A child’s squirming could
put the belt out of position. In the event
of an accident, children are afforded the
best safety restrained by a proper Child
Restraint System in the rear seats.
If a larger child over age 13 must be
seated in the front seat, the child must
be securely restrained by the available
lap/shoulder belt and the seat should be
placed in the rearmost position.
If the shoulder belt portion slightly
touches the child’s neck or face, try
placing the child closer to the center
of the vehicle. If the shoulder belt still
touches their face or neck, they need to
be returned to an appropriate booster
seat in the rear seat.
WARNING

[Always make sure larger children’s
seat belts are worn and properly
adjusted.

[NEVER allow the shoulder belt to
contact the child’s neck or face.

[Do not allow more than one child to
use a single seat belt.

ORG3EV031086
Forward-facing Child Restraint System
A forward-facing Child Restraint System
provides restraint for the child’s body
with a harness. Keep children in a
forward-facing Child Restraint System
with a harness until they reach the top
height or weight limit allowed by your
Child Restraint System’s manufacturer.
Once your child outgrows the forward-
facing Child Restraint System, your child
is ready for a booster seat.
Booster seats
A booster seat is a Child Restraint
System designed to improve the fit of
the vehicle’s seat belt system. A booster
seat positions the seat belt so that it
fits properly over the stronger parts of
your child’s body. Keep your children in
booster seats until they are big enough
to fit in a seat belt properly.
For a seat belt to fit properly, the lap belt
must lie comfortable across the upper
thighs, not the stomach. The shoulder
belt should lie comfortable across the
shoulder and chest and not across the
neck or face. Children under age 13
must always be properly restrained to
minimize the risk of injury in an accident,
sudden stop or sudden maneuver.
Installing a Child Restraint
System (CRS)
WARNING
Before installing your Child Restraint
System always:
Read and follow the instructions
provided by the manufacturer of the
Child Restraint System.
Failure to follow all warnings and
instructions could increase the risk of
the SERIOUS INJURY or DEATH if an
accident occurs.
WARNING
If the vehicle head restraint prevents
proper installation of a Child Restraint
System, the head restraint of the
respective seating position shall be
readjusted or entirely removed.
After selecting a proper Child Restraint
System for your child and checking that
the Child Restraint System fits properly
on the seating position, there are three
general steps for a proper installation:

[Properly secure the Child Restraint
System to the vehicle. All Child
Restraint Systems must be secured
to the vehicle with the lap belt or lap
part of a lap/shoulder belt or with the
lower anchor and/or tether anchor
and/or with the support leg.

Seats and Safety System

[Make sure the Child Restraint System
is firmly secured. After installing a
Child Restraint System to the vehicle,
push and pull the seat forward and
from side-to-side to verify that it is
securely attached to the seat. A Child
Restraint System secured with a seat
belt should be installed as firmly as
possible. However, some side-to-side
movement can be expected.
When installing a Child Restraint
System, adjust the vehicle seat and
seatback (up and down, forward
and rearward) so that your child fits
in the Child Restraint System in a
comfortable manner.

[Secure the child in the Child
Restraint System. Make sure the
child is properly strapped in the Child
Restraint System according to the
Child Restraint System manufacturer’s
instructions.
CAUTION
A Child Restraint System in a closed
vehicle can become very hot. To prevent
burns, check the seating surface and
buckles before placing your child in the
Child Restraint System.
Lower Anchors and Tether for
Children (LATCH System)
The LATCH system holds a Child
Restraint System during driving and in
an accident. This system is designed
to make installation of the Child
Restraint System easier and reduce
the possibility of improperly installing
your Child Restraint System. The LATCH
system uses anchors in the vehicle and
attachments on the Child Restraint
System. The LATCH system eliminates
the need to use seat belts to secure the
Child Restraint System to the rear seats.
Lower anchors are metal bars built into
the vehicle. There are two lower anchors
for each LATCH seating position that will
accommodate a Child Restraint System
with lower attachments.
To use the LATCH system in your vehicle,
you must have a Child Restraint System
with LATCH attachments.
The Child Restraint System manufacturer
will provide you with instructions on how
to use the Child Restraint System with its
attachments for the LATCH anchorages.
