[A] : Lower Anchor Position Indicator(Type A- ,Type B- ),[B] : Lower Anchor
The lower anchor position indicator
symbols are located on the left and right
rear seat backs to identify the position
of the lower anchors in your vehicle (see
arrows in illustration).
The LATCH anchors are located between
the seatback and the seat cushion of the
rear seat left and right outboard seating
positions.
WARNING
Before installing the Child Restraint
System, make sure that there are no
objects (e.g. toy, pen, wire) around the
lower anchor area. Those objects may
damage either the seat belt system or
the Child Restraint System during the
installment procedure. If necessary,
have the vehicle inspected by an
authorized HYUNDAI dealer.
Securing a Child Restraint System
with the “LATCH Anchors System”
To install a LATCH-compatible Child
Restraint System in either of the rear
outboard seating positions:
1. Move the seat belt buckle away from
the lower anchors.
2. Move any other objects away from
the anchorages that could prevent
a secure connection between the
Child Restraint System and the lower
anchors.
3. Place the Child Restraint System on
the vehicle seat, then attach the seat
to the lower anchors according to the
instructions provided by the Child
Restraint System manufacturer.
4. Follow the instructions of the Child
Restraint System’s manufacturer for
proper installation and connection of
the lower attachments on the Child
Restraint System to the lower anchors.

WARNING
Take the following precautions when
using the LATCH system:
• Read and follow all installation
instructions provided with your Child
Restraint System.
• To prevent the child from reaching
and taking hold of unretracted
seat belts, buckle all unused rear
seat belts and retract the seat belt
webbing behind the child. Children
can be strangled if a shoulder belt
becomes wrapped around their neck
and the seat belt tightens.
• NEVER attach more than one
Child Restraint System to a single
anchorage. This could cause the
anchor or attachment to come loose
or break.
• Always have the LATCH system
inspected by your dealer after an
accident. An accident can damage
the LATCH system and may not
properly secure the Child Restraint
System.
NOTICE
The recommended weight for the
LATCH system is under 65 lb. (30 kg).
How to determine an appropriate child
restraint weight: Child weight + Child
restraint weight < 65 lb. (30kg)
Securing a Child Restraint System
seat with “Tether Anchor” system
OTL035034
First secure the child restraint with
the LATCH lower anchors or the seat
belt. If the child restraint manufacturer
recommends that the top tether strap
be attached, attach and tighten the
top tether strap to the top tether strap
anchor.
Child restraint hook holders are located
on the rear of the seatbacks.

Seats & Safety System

ONX4030034
To install the tether anchor:
1. Route the Child Restraint System
top-tether strap over the seatback.
Route the tether strap under the
head restraint and between the head
restraint posts, or route the tether
strap over the top of the vehicle
seatback. Make sure the strap is not
twisted.
2. Connect the tether strap hook to
the tether anchor, then tighten the
top-tether strap according to the
instructions of your Child Restraint
System’s manufacturer to firmly
attach the Child Restraint System to
the seat.
3. Check that the Child Restraint System
is securely attached to the seat by
pushing and pulling the seat forward-
and-back and side-to-side.
WARNING
Take the following precautions when
installing the top-tether:
• Read and follow all installation
instructions provided with your Child
Restraint System.
• NEVER attach more than one
Child Restraint System to a single
tether anchor. This could cause the
anchorage or attachment to come
loose or break.
• Do not attach the tether strap to
anything other than the correct
top-tether anchor. It may not work
properly if attached to something
else.
• Child Restraint System anchors are
designed to withstand only those
loads imposed by correctly fitted
Child Restraint System.
Under no circumstances are the
anchors to be used for adult seat
belts or harnesses or for attaching
other items or equipment to the
vehicle.

Securing a Child Restraint System
with a lap/shoulder belt
WARNING
ALWAYS place a rearward-facing Child
Restraint System in the rear seat of the
vehicle.
Placing a rearward-facing child restraint
in the front seat can result in serious
injury or death if the Child Restraint
System is struck by an inflating air bag.
When not using the LATCH system, all
Child Restraint Systems must be secured
to a rear seat with the lap part of a lap/
shoulder belt.
OHI038145
Automatic locking mode
Since all passenger seat belts move
freely under normal conditions and
only lock under extreme or emergency
conditions (emergency locking mode),
you must manually pull the seat belt all
the way out to shift the retractor to the
"Automatic Locking" mode to secure a
Child Restraint System.
The "Automatic Locking" mode will help
prevent the normal movement of the
child in the vehicle from causing the
seat belt to loosen and compromise
the Child Restraint System. To secure a
Child Restraint System, use the following
procedure.
To install a Child Restraint System on the
rear seats, do the following:
1. Place the Child Restraint System on a
rear seat and route the lap/shoulder
belt around or through the Child
Restraint System, following the Child
Restraint System manufacturer’s
instructions. Make sure the seat belt
webbing is not twisted.
Information
When using the rear center seat belt, you
should also refer to the "Rear Seat Belt –
Passenger's 3-point system" section in this
chapter.

Curtain air bags
ONX4030040
OTM030032
Curtain air bags are located along both
sides of the roof rails above the front and
rear doors.
They are designed to help protect the
heads of the front seat occupants and
the rear outboard seat occupants in
certain side impact collisions.
The curtain air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity, angle, speed and impact.For vehicles equipped with a rollover
sensor the side and/or curtain air bags
and pre-tensioners on both sides of
the vehicle may deploy if a rollover or
possible rollover is detected.
The curtain air bags are not designed
to deploy in all side impact or rollover
situations.
WARNING
To reduce the risk of serious injury or
death from an inflating curtain air bag,
take the following precautions:
•
All seat occupants must wear
seat belts at all times to help keep
occupants positioned properly.
• Properly secure Child Restraint
System as far away from the door as
possible.
• Do not place any objects over the air
bag. Also, do not attach any objects
around the area the air bag inflates
such as the door, side door glass,
front and rear pillar, roof side rail.
• Do not hang other objects except
clothes, especially hard or breakable
objects.
In an accident, it may cause vehicle
damage or personal injury.
• Do not allow passengers to lean their
heads or bodies onto doors, put their
arms on the doors, stretch their arms
out of the window, or place objects
between the doors and seats.
• Do not open or repair the side curtain
air bags.

ONX4050015
[A] : Wireless Charging Pad (In-vehicle Authentication Pad)
Information
After reconnecting the vehicle battery

may take time to operate due to remote
renewal of security information. In this
case, when you lock or unlock the doors
using your smartphone Digital Key, it
may take a little longer for the vehicle to
authenticate. Hold your smartphone near
the NFC door handle sensor for a few
seconds or until you hear the door locks
actuate. Note that if your vehicle is parked in an
area where cell coverage is weak, the
smartphone Digital Key can still be used on
for a limited number of times to unlock and
start your vehicle.
After starting your vehicle, it is
recommended to leave your smartphone
on the wireless charging pad until cell
phone service is stronger and digital key
authentication can occur.
Once authentication is complete, the
wireless charger will turn on (wireless
charging LED will illuminate).
CAUTION
The engine can be turned on if the
registered smartphone or card key is
placed on the interior authentication
pad (wireless charger). Do not leave
children unattended in the vehicle
when using the smartphone Digital Key.
Serious injury or death can occur.
Do not leave anyone in the vehicle
without knowledge of the Digital Key
system when using the smartphone
Digital Key. Always have the registered
digital key (smartphone) or card key
with you to prevent vehicle theft when
