Safety Precautions
Adjusting the seats so that you are sitting
in a safe, comfortable position plays an
important role in driver and passenger
safety together with the seat belts and
air bags in an accident.
WARNING
Do not use a cushion that reduces
friction between the seat and the
passenger. The passenger’s hips may
slide under the lap portion of the seat
belt during an accident or a sudden
stop. Serious or fatal internal injuries
could result because the seat belt
cannot operate properly.
Air bags
You can take steps to reduce the risk
of being injured by an inflating air bag.
Sitting too close to an air bag greatly
increases the risk of injury in the event
the air bag inflates.
The National Highway Traffic Safety
Administration (NHTSA) recommends
that drivers allow at least 10 inches (25
cm) between the center of the steering
wheel and their chest.
WARNING
To reduce the risk of serious injury or
death from an inflating air bag, take the
following precautions:
• Adjust the driver’s seat as far to the
rear as possible while maintaining
the ability to maintain full control of
the vehicle.
• Adjust the front passenger seat as far
to the rear as possible.
• Hold the steering wheel by the rim
with hands at the 9 o’clock and 3
o’clock positions to minimize the risk
of injuries to your hands and arms. •
NEVER place anything or anyone
between the steering wheel and the
air bag.
• Do not allow the front passenger to
place feet or legs on the dashboard
to minimize the risk of leg injuries.
Seat belts
Always fasten your seat belt before
starting any trip.
At all times, passengers should sit
upright and be properly restrained.
Infants and small children must be
restrained in appropriate child restraint
systems. Adults and children who
have outgrown a booster seat must be
restrained using the seat belts.
WARNING
Take the following precautions when
adjusting your seat belt:
• NEVER use one seat belt for more
than one occupant.
• Always position the seatback upright
with the lap portion of the seat belt
snug and low across the hips.
• NEVER allow children or small infants
to ride on a passenger’s lap.
• Do not route the seat belt across your
neck, across sharp edges, or reroute
the shoulder strap away from your
body.
• Do not allow the seat belt to become
caught or jammed.

Safety System

NOTICE
If you are not able to smoothly pull
enough of the seat belt out from the
retractor, firmly pull the seat belt out
and release it. After release, you will be
able to pull the belt out smoothly.
Height adjustment
You can adjust the height of the shoulder
belt anchor to one of the three different
positions for maximum comfort and
safety. The shoulder portion should be
adjusted so it lies across your chest and
midway over your shoulder nearest the
door, not over your neck. To adjust the
height of the seat belt anchor, lower
or raise the height adjuster into an
appropriate position.
„„Front seat
ODN8039072L
To raise the height adjuster, pull it up
(1). To lower it, push it down (3) while
pressing the height adjuster button (2).
Release the button to lock the anchor
into position. Try sliding the height
adjuster to make sure that it has locked
into position.
OHI038142
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 twisted, then
try again.
Rear Seat Belt – Passenger’s 3-point
system with convertible locking
retractor
This type of seat belt combines the
features of both an emergency locking
retractor seat belt and an automatic
locking retractor seat belt. Convertible
retractor type seat belts are installed
in the rear seat positions to help
accommodate the installation of child
restraint systems. Although a convertible
retractor is also installed in the front
passenger seat position, NEVER place
any infant/child restraint system in the
front seat of the vehicle.

03
3-23
To fasten your seat belt:
Pull the seat belt out of the retractor
and insert the metal tab into the buckle.
There will be an audible “click” when
the tab locks into the buckle. When
not securing a child restraint, the seat
belt operates in the same way as the
driver’s seat belt (Emergency Locking
Retractor Type). It automatically adjusts
to the proper length only after the lap
belt portion of the seat belt is adjusted
manually so that it fits snugly across your
hips.
When the seat belt is fully extended from
the retractor to allow the installation 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.
NOTICE
Although the seat belt retractor
provides the same level of protection
for seated passengers in either
emergency or automatic locking
modes, the emergency locking mode
allows seated passengers to move
freely in their seat while keeping
some tension on the belt. During a
collision or sudden stop, the retractor
automatically locks the belt to help
restrain your body.
To deactivate the automatic locking
mode, unbuckle the seat belt and allow
the belt to fully retract.
OHI038142
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 twisted, then
try again.
Rear center seat belt
ODN8039074L
When using the rear center seat belt, the
buckle with the “CENTER” mark must be
used.
WARNING
Make sure that the seatback is locked in
place when using the rear center seat
belt.
If not, the seatback may move when
there is a sudden stop or collision,
which could result in serious injury.

03
3-35
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
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.
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, following the restraint
manufacturer’s instructions. Be 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.
OHI038146
2. Fasten the lap/shoulder belt latch
into the buckle. Listen for the distinct
“click” sound.

Safety System
3-36
Information
Position the release button so that it is easy
to access in case of an emergency.
OLF034076
3. Pull the shoulder portion of the
seat belt all the way out. When the
shoulder portion of the seat belt
is fully extended, it will shift the
retractor to the “Automatic Locking”
(child restraint) mode.
OLF034075
4. Slowly allow the shoulder portion of
the seat belt to retract and listen for
an audible “clicking” or “ratcheting”
sound. This indicates that the retractor
is in the “Automatic Locking” mode.
If no distinct sound is heard, repeat
steps 3 and 4.
5. Remove as much slack from the belt
as possible by pushing down on the
child restraint system while feeding
the shoulder belt back into the
retractor.
6. Push and pull on the child restraint
system to confirm that the seat belt
is holding it firmly in place. If it is not,
release the seat belt and repeat steps
2 through 6.
7. Double check that the retractor is in
the “Automatic Locking” mode by
attempting to pull more of the seat
belt out of the retractor. If you cannot,
the retractor is in the “Automatic
Locking” mode.
If your CRS (child restraint system)
manufacturer instructs or recommends
you to use a tether anchor with the lap/
shoulder belt, refer to the previous pages
for more information.
Information
When the seat belt is allowed to retract to
its fully stowed position, the retractor will
automatically switch from the “Automatic
Locking” mode to the emergency lock
mode for normal adult usage.
WARNING
If the retractor is not in the “Automatic
Locking” mode, the child restraint
can move when your vehicle turns or
stops suddenly. A child can be seriously
injured or killed if the child restraint
is not properly anchored in the car,
including manually pulling the seat belt
all the way out to shift the rectractor to
the “Automatic Locking” mode.
To remove the child restraint, press the
release button on the buckle and then
pull the lap/shoulder belt out of the
restraint and allow the seat belt to retract
fully.

Safety System
3-44
• 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.
• There are even circumstances under
which contact with the air bag can
cause fatal injuries, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to help reduce the
risk of being injured by an inflating air
bag. The greatest risk is sitting too close
to the air bag. An air bag needs about 10
inches (25 cm) of space to inflate. NHTSA
recommends that drivers allow at least
10 inches (25 cm) between the center of
the steering wheel and the chest. WARNING
To reduce the risk of serious injury or
death from an inflating air bag, take the
following precautions:
• NEVER place a child restraint in the
front passenger seat.
Always properly restrain children
under age 13 in the rear seats of the
vehicle.
• Adjust the front passenger’s and
driver’s seats as far to the rear as
possible while allowing you to
maintain full control of the vehicle.
• Hold the steering wheel with
hands at the 9 o’clock and 3 o’clock
positions.
• NEVER place anything or anyone
between the air bag and the seat
occupant.
• Do not allow the front passenger
to place their feet or legs on the
dashboard.

Do Not Install a Child Restraint in the Front Passenger’s Seat
OHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING
• NEVER place a rear-facing or front-
facing child restraint in the front
passenger’s seat of the vehicle.
• An inflating frontal air bag could
forcefully strike a child resulting in
serious injury or death.
• Always properly restrain children in
an appropriate child restraint in the
rear seat of the vehicle.
Why Didn’t My Air Bag Go Off in
a Collision?
Air bags are not designed to inflate in
every collision. There are certain types
of accidents in which the air bag would
not be expected to provide additional
protection. These include rear impacts,
second or third collisions in multiple
impact accidents, as well as low speed
impacts. Damage to the vehicle indicates
a collision energy absorption, and is not
an indicator of whether or not an air bag
should have inflated.
WARNING
To reduce the risk of an air bag
deploying unexpectedly and causing
serious injury or death:
• Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
• Do not perform maintenance on or
around the air bag sensors. If the
location or angle of the sensors is
altered, the air bags may deploy
when they should not or may not
deploy when they should.
• Do not install bumper guards or
replace the bumper with a non-
genuine HYUNDAI parts. This may
adversely affect the collision and air
bag deployment performance.
• Place the ignition switch in the
LOCK/OFF or ACC position when the
vehicle is being towed to prevent
inadvertent air bag deployment.
• Have all air bag repairs conducted by
an authorized HYUNDAI dealer.
