When the seat belt is fully extended
from the retractor to allow the instal-
lation of a child restraint system, the
seat belt operation changes to allow
the belt to retract, but not to extend
(Automatic Locking Retractor Type).
Refer to the "Using a Child Restraint
System" section in this chapter.
Although the seat belt retractor
provides the same level of protec-
tion for seated passengers in
either emergency or automatic
locking modes, the emergency
locking mode allows seated pas-
sengers to move freely in their
seat while keeping some tension
on the belt. During a collision or
sudden stop, the retractor auto-
matically locks the belt to help
restrain your body.
To deactivate the automatic lock-
ing mode, allow the unbuckled
seat belt to fully retract.
To release your seat belt:
Press the release button (1) in the
locking buckle.
When it is released, the belt should
automatically draw back into the
retractor. If this does not happen,
check the belt to be sure it is not twist-
ed, then try again.
Pre-tensioner seat belt (Driver and front passenger)
Retractor Pre-tensioner
Your vehicle is equipped with driver’s
and front passenger’s Pre-tensioner
Seat Belts. The purpose of the pre-
tensioner is to make sure the seat
belts fit tightly against the occupant’s
body in certain frontal collisions. The
pre-tensioner seat belts may be acti-
vated in crashes where the frontal col-
lision is severe enough.
If the system senses excessive ten-
sion on the driver’s or passenger’s
seat belt when the pre-tensioner acti-
vates, the load limiter inside the pre-
tensioner will release some of the
pressure on the affected seat belt.
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
collisions, the pre-tensioner will acti-
vate and pull the seat belt into tighter
contact against the occupant’s body.

Safety system of your vehicle
Seat Belt Anchor Pre-tensioner
The purpose of the Seat Belt Anchor
Pre-tensioner is to help the lap belt fit
tightly against the occupant's lower
body in certain frontal collisions. The
Seat Belt Anchor Pre-tensioner may
be activated in crashes where the
frontal collision is severe enough.Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanism
deploys during a collision, the
pre-tensioners become hot and
can burn you.
WARNING
Always wear your seat belt and
sit properly in your seat.
Do not use the seat belt if it is
loose or twisted. A loose or
twisted seat belt will not pro-
tect you properly in an acci-
dent.
Do not place anything near the
buckle. This may adversely
affect the buckle and cause it
to function improperly.
Always replace your pre-ten-
sioners after activation or an
accident.
NEVER inspect, service, repair
or replace the pre-tensioners
yourself. This must be done by
an authorized HYUNDAI dealer.
Do not hit the seat belt assem-
blies.

Safety system of your vehicle
This vehicle is equipped with an
Advanced Supplemental Air Bag
System for the driver's seat and front
passenger's seats.
The front air bags are designed to
supplement the three-point seat
belts. For these air bags to provide
protection, the seat belts must be
worn at all times when driving.
You can be severely injured or killed
in an accident if you are not wearing
a seat belt. Air bags are designed to
supplement seat belts, but do not
replace them. Also, air bags are not
designed to deploy in every collision.
In some accidents, the seat belts are
the only restraint protecting you. AIR BAG SAFETY PRECAUTIONS
ALWAYS use seat belts and child restraints - every trip, every time,
everyone! Even with air bags, you can be seriously injured or killed in
a collision if you are improperly belted or not wearing your seat belt
when the air bag inflates.
NEVER place a child in any child restraint or booster seat in the front
passenger seat. An inflating air bag could forcefully strike the infant
or child causing serious or fatal injuries.
ABC - Always Buckle Children under age 13 in the back seat. It is the
safest place for children of any age to ride. If a child age 13 or older
must be seated in the front seat, he or she must be properly belted
and the seat should be moved as far back as possible.
All occupants should sit upright with the seatback in an upright posi-
tion, centered on the seat cushion with their seat belt on, legs com-
fortably extended and their feet on the floor until the vehicle is parked
and the engine is turned off. If an occupant is out of position during
an accident, the rapidly deploying air bag may forcefully contact the
occupant causing serious or fatal injuries.
You and your passengers should never sit or lean unnecessarily
close to the air bags or lean against the door or center console.
Move your seat as far back as possible from front air bags, while still
maintaining control of the vehicle. The U.S. National Highway Traffic
Safety Administration (NHTSA) recommends that drivers allow at
least 10 inches (25 cm) between the center of the steering wheel and
the chest.

Where Are the Air Bags?
Driver's and passenger's frontair bags
Your vehicle is equipped with a
Advanced Supplemental Restraint
System (SRS) and lap/shoulder belts
at both the driver and passenger
seating positions.
The SRS consists of air bags which
are located in the center of the steer-
ing wheel, in the driver's side lower
crash pad below the steering wheel
column and the passenger's side
front panel pad above the glove box.
The air bags are labeled with the let-
ters "AIR BAG" embossed on the
pad covers. The purpose of the SRS is to provide
the vehicle's driver and front passen-
gers with additional protection than
that offered by the seat belt system
alone. The SRS uses sensors to
gather information about the driver’s
and front passenger's seat belt
usage and impact severity.
The seat belt buckle sensors deter-
mine if the driver and front passen-
ger's seat belts are fastened. These
sensors provide the ability to control
the SRS deployment based on
whether or not the seat belts are fas-
tened, and how severe the impact is.
The advanced SRS offers the ability
to control the air bag inflation within
two levels. A first stage level is pro-
vided for moderate-severity impacts.
A second stage level is provided for
more severe impacts.
According to the impact severity, and
seat belt usage, the SRS Control
Module (SRSCM) controls the air
bag inflation. Failure to properly wear
seat belts can increase the risk or
severity of injury in an accident.

Side air bags
Your vehicle is equipped with a side
air bag in each front seat. The pur-
pose of the air bag is to provide the
vehicle's driver and the front passen-
ger with additional protection than
that offered by the seat belt alone.
OLF034042N
OLF034043
To reduce the risk of serious
injury or death from an inflating
front air bags, take the following
precautions:
Seat belts must be worn at all
times to help keep occupants
positioned properly.
Move your seat as far back as
possible from front air bags,
while still maintaining control
of the vehicle.
Never lean against the door or
center console.
Do not allow the front passen-
ger to place their feet or legs
on the dashboard.(Continued)
(Continued)
No objects (such as crash pad
cover, cellular phone holder,
cup holder, perfume or stick-
ers) should be placed over or
near the air bag modules on
the steering wheel, instrument
panel, windshield glass, and
the front passenger's panel
above the glove box. Such
objects could cause harm if
the vehicle is in a crash
severe enough to cause the
air bags to deploy.
Do not attach any objects on
front windshield and inside
mirror.

The side air bags are designed to
deploy only during certain side impact
collisions, depending on the crash
severity, angle, speed and point of
impact.
The side and curtain air bags on
both sides of the vehicle may deploy
if a rollover or possible rollover is
detected.
The side air bags are not designed to
deploy in all side impact or rollover
situations.To reduce the risk of serious
injury or death from an inflating
side air bag, take the follo
wing
precautions:
Seat belts must be worn at all
times to help keep occupants
positioned properly.
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.
Hold the steering wheel at the 9
o'clock and 3 o'clock positions,
to minimize the risk of injuries
to your hands and arms.
Do not use any accessory
seat covers. This could reduce
or prevent the effectiveness
of the system.
Do not place any objects over
the air bag or between the air
bag and yourself.
(Continued)
WARNING (Continued)Also, do not attach any
objects around the area the
air bag inflates such as the
door, side door glass, front
and rear pillar.
Do not place any objects
between the door and the
seat. They may become dan-
gerous projectiles if the side
air bag inflates.
Do not install any accessories
on the side or near the side air
bags.
Do not put any objects
between the side air bag label
and seat cushion. It could
cause harm if the vehicle is in
a crash severe enough to
cause the air bags to deploy.
Do not cause impact to the
doors when the ignition
switch is in the ON position or
this may cause the side air
bags to inflate.
If the seat or seat cover is
damaged, have the vehicle
checked and repaired by an
authorized HYUNDAI dealer.
