Hyundai's SRS Supplementary Restraint System consists of airbags installed under the lining in the middle of the steering wheel and in the panel on the front passenger side above the glove box. The purpose of this system is to provide additional safety for the driver and/or front passenger in addition to the seat belt system in the event of moderate to severe frontal impacts.

Note. Be sure to read the information about the SRS system on the labels located on the back of the sun visor on the driver's side and inside the glove box.
The SRS system is designed to complement and work in conjunction with, and is not a replacement for, the driver's and front passenger's three-point seat belts. Therefore, while in a car, always fasten your seat belts. It must be taken into account that the airbags are triggered in sufficiently strong frontal impacts and only once. Therefore, you must always wear seat belts.
The airbags do not deploy in minor impacts when the seat belts are sufficient to protect the occupants.
Pic. 1.126. An example of accidents in which airbags do not deploy
Airbags are not designed to deploy in rear, side, or rollover impacts. In addition, the airbags will not deploy in a frontal impact at speeds below a certain threshold vehicle speed (pic. 1.126).
Do not replace detached SRS components by yourself or subject them to impact, as this may result in injury.
The driver should adjust the seat so that he is as far away from the airbag as possible, but has easy access to all vehicle controls. Do not lean or sit too close to the airbag when the vehicle is in motion, as this could cause serious injury when the airbag deploys.
Do not place objects of any kind on or near the airbag modules - on the steering wheel, instrument panel and front passenger panel, they may cause injury when the airbags deploy.
If the airbags have deployed, they must be replaced by an authorized Hyundai dealer.
Do not strike the wires and components of the additional passive safety system (SRS) – this may cause the airbags to deploy unexpectedly or the system to fail.
No child restraint is allowed (child seats) in the front seat. In the event of an accident, the deployment of the front passenger's airbag could injure or kill the occupant in the restraint (child seat) child. Keep children out of the area in front of the front seat. If an adult child is sitting in the front seat, they must be fastened with a seat belt and the seat must be pushed back as far as possible.
For maximum protection in all types of collisions, all occupants, including the driver, must always wear their seat belts, regardless of the presence of an airbag in that seat, to minimize the risk of injury or death in the event of an accident (accidents).
In order to provide protection in a collision, the SRS airbags inflate very quickly and with great force. If the occupant is not wearing a seat belt, the airbag may hit the occupant hard, resulting in serious or even fatal injury.
Functions and elements of the SRS system
Additional passive safety system (SRS) includes the following components:
- driver's frontal airbag assembly;
- front passenger airbag assembly;
- SRS warning lamp (SRI);
- SRS electronic control unit (additional passive safety system) (SRSCM).
Pic. 1.127. Airbag Deployment
SRS electronic control unit (additional passive safety system) (SRSCM) constantly monitors all system components when the ignition key is in the «ON» («On») and determines if a frontal or near-frontal impact was strong enough to deploy the airbags (pic. 1.127).
SRS warning lamp (SRI) on the instrument panel flashes for approximately 6 seconds after the ignition key is turned to the «ON» (On) or after starting the engine, after which it goes out.
The airbags are located in the middle of the steering wheel and in the panel opposite the front passenger seat above the glove box. When the SRS ECM (additional passive safety system) (SRSCM) detects a frontal impact of sufficient force, it automatically deploys the airbags.
Pic. 1.128. The panel under which the front passenger airbag is located
During deployment, the airbag expanding when inflated with gas knocks out the cover, which breaks along a special seam (pic. 1.128).
A fully deployed airbag in combination with a properly fastened seat belt slows the forward movement of the driver or front passenger, thereby reducing the risk of head and chest injury.
Attention! Do not install or place any foreign objects (cup holder, cassette holder, sticker, etc.) on the front panel above the stowage (glove) box on vehicles equipped with a front passenger airbag. When the front passenger airbag deploys, these objects can be thrown into the passenger compartment and cause serious injury.
After fully inflating the airbag, the airbag immediately begins to descend, providing the driver with a forward view.
Attention! When the SRS airbag deploys, a sharp loud pop is heard and some smoke and dust is emitted (powder). These phenomena are not dangerous and are normal. However, dust (powder), produced when airbags are inflated, can irritate the skin. After deploying the airbags, be sure to wash your face and hands with soap and warm water.
The SRS only works when the ignition key is in the «ON» («On»). If the SRS warning light does not come on or stays on after flashing for approximately 6 seconds after the ignition key is turned to «ON» («On»), after starting the engine or lights up while driving, this indicates a malfunction of the SRS system.
Before changing the fuse or disconnecting the wire from the battery terminal, turn the ignition key to the «LOCK» («blocking») or remove the key from the ignition. Never remove the SRS fuse with the ignition key in the «ON» («On»), otherwise the SRS warning light will come on.
Side airbags (optional equipment)

Pic. 1.130. Side airbag impact sensor
The vehicle may be equipped with side airbags for each front seat. The side airbag provides protection for the driver and front passenger in addition to the seat belts. The side airbags are only designed to deploy in some side impacts, depending on the severity and angle of impact, vehicle speed, and impact location. Side airbags are not designed to deploy in all side impact situations (pic. 1.130).
