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.
