The vehicles are equipped with a
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 Child Restraint Systems - 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 System or booster seat in
the front passenger seat, unless the air bag is deactivated.
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.WARNING

SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration. The
system checks the air bag electrical
system for malfunctions. The light indi-
cates that there is a potential problem
with your air bag system.During a moderate to severe frontal
collision, sensors will detect the vehi-
cle’s rapid deceleration. If the rate of
deceleration is high enough, the con-
trol unit will inflate the front air bags,
at the time and with the force needed.
The front air bags help protect the driv-
er and front passenger by responding
to frontal impacts in which seat belts
alone cannot provide adequate
restraint. When needed, the side air
bags help provide protection in the
event of a side impact by supporting
the side upper body area.
• Air bags are activated (able to inflate
if necessary) only when the ignition
switch is in the ON position.
• Air bags inflate in the event of certain
frontal or side collisions to help pro-
tect the occupants from serious
physical injury.
• There is no single speed at which the
air bags will inflate. Generally, air bags
are designed to inflate based upon
the severity of a collision and its direc-
tion. These two factors determine
whether the sensors produce an elec-
tronic deployment/inflation signal.
Safety system of your vehicle
If your SRS malfunctions, the
air bag may not inflate properly
during an accident increasing
the risk of serious injury or
death.
If any of the following conditions
occur, your SRS is malfunction-
ing:
•The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
•The light stays on after illumi-
nating for approximately six
seconds.
•The light comes on while the
vehicle is in motion.
•The light blinks when the
engine is running.
We recommend that an author-
ized HYUNDAI dealer inspect the
SRS as soon as possible if any
of these conditions occur.
