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 to a single anchor.
This could cause the anchor or
attachment to come loose or break.

[ Always have the LATCH system
inspected by your authorized
HYUNDAI dealer after an accident.
An accident can damage the LATCH
system and may not properly secure
the child restraint.
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 seat with
“Tether Anchor” system
OCN7030032
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.
WARNING
Take the following precautions when
installing the tether strap:

[Read and follow all installation
instructions provided with your child
restraint system.

[ NEVER attach more than one child
restraint to a single tether anchor.
This could cause the anchor or
attachment to come loose or break.

[ Do not attach the tether strap to
anything other than the correct
tether anchor. It may not work
properly if attached to something
else.

[ Do not use the tether anchors for
adult seat belts or harnesses, or for
attaching other items or equipment
to the vehicle.

Seats & Safety System3-32
OCN7030031
To install the tether anchor:
1. Route the child restraint tether strap over the child restraint 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 tether
strap according to the child seat
manufacturer’s instructions to firmly
secure the child restraint to the seat.
3. Check that the child restraint is securely attached to the seat by
pushing and pulling the seat forward-
and-back and side-to-side.
Securing a child restraint with lap/
shoulder belt
When not using the LATCH system, all
child restraints must be secured to a
vehicle rear seat with the lap part of a
lap/shoulder belt.
WARNING
ALWAYS place a rear-facing child
restraint in the rear seat of the vehicle.
Placing a rear-facing child restraint in
the front seat can result in serious injury
or death if the child restraint is struck
by an inflating air bag.
OHI038145
Automatic locking mode
Since all passenger seat belts move
fr
eely 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.
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.

Seats & Safety System3-40
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 restraints 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 attempt to open or repair
the side curtain air bags yourself.
If necessary, have the air bag be
inspected by an authorized HYUNDAI
dealer.
How Does the Air Bag System
Operate?
OCN7030061N
The SRS consists of the following
components:
1. Driver’s front air bag module
2. Passenger’s front air bag module
3. Side air bag modules (front)
4. Curtain air bag modules
5. Retractor pre-tensioner assemblies
6. Air bag warning light
7. SRS control module (SRSCM) /
Rollover sensor
8. Front impact sensors
9. Side impact sensors (acceleration)
10. Side impact sensors (pressure)
11. Occupant classification system
12. Driver’s and front passenger’s seat belt buckle sensors
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the Engine Start/Stop button is in the
ON position or approximately within
3 minutes after the ignition is off to
determine if a crash impact is severe
enough to require air bag deployment or
pre-tensioner seat belt deployment.
