The passive safety system (SRS) of the car combines front and side airbags for the driver and passenger in the front seat, inflatable side curtains (depending on configuration), inertial seat belts for the driver and all passengers

The seat belts for the driver and front passenger are equipped with pyrotechnic pretensioners installed in inertial coils.

Hyundai Solaris Security System Design Features

Airbags do not replace seat belts.

Moreover, when the car is moving, the driver and front passenger must be sure to wear their seat belts, since in the event of a traffic accident, a deployed airbag itself can cause serious injury to a person who is not wearing a seat belt.

In addition, passengers in the rear seat must be fastened with seat belts.

In the event of an accident, an unbelted passenger in the rear seat can cause injury and serious injury to all passengers in the vehicle.

Do not install or place any accessories on the front panel in front of the passenger above the glove box in the vehicle. Such objects may move violently and cause injury if the passenger air bag inflates.

When installing an air freshener inside the passenger compartment, it should not be placed near appliances or on the surface of the dashboard. Such items can also cause injury when the passenger airbag deploys.

The deployment of airbags can be accompanied by a loud noise and the spread of fine dust throughout the cabin.

Dust released during the opening of the pillows can cause skin or eye irritation, and increase the asthmatic response of some individuals.

After an accident involving the deployment of airbags, always wash all exposed skin thoroughly with warm water and soapy water.

Before changing the fuse or disconnecting the battery, turn the ignition key to the "LOCK" position and remove it from the ignition.

Never remove or replace fuses that are related to the airbag system with the ignition key in the "ON" position.

Failure to follow this warning will cause the airbag warning light to come on.

To turn off the signaling device, you will have to contact a specialized auto repair center.

The SRS airbag system is designed to deploy only when the force of the frontal impact is large enough and its direction is no more than 30 ° to the longitudinal axis of the vehicle.

The front airbags are not designed to deploy in the event of a side impact, rear impact or rollover.

Children under the age of 12 must always be in the back seat and must be securely restrained.

Never allow children to ride in the front passenger seat.

If a child over 12 years old is seated in the front seat, they must be securely fastened with seat belts, the seat must be moved to the rearmost position, and the front passenger airbag must be deactivated.

The front passenger airbag should only be deactivated when the ignition is turned off, otherwise the airbag control unit may fail.

The SRS includes the following elements:

- the driver"s airbag module, located in the steering wheel hub and consisting of a folded airbag shell and a gas generator;

- front passenger airbag module, located in the instrument panel on the passenger side and consisting of a folded airbag shell and an inflator. Differs from the driver"s airbag in shape and large volume;

- driver and front passenger side airbag modules located in the outer side x parts of the front seat backrests and consisting of a folded cushion shell and a gas generator;

- curtain airbag modules for the driver and passengers, located under the facings of the front and rear pillars of the body and consisting of a folded airbag shell and a gas generator;

– an electronic control unit installed under the lining of the floor tunnel and controlling the system.

The ECU incorporates micromechanical sensors that measure the longitudinal and lateral acceleration of the car in a collision.

The ECU evaluates the impact force by comparing the values ​​it receives from the front impact sensor, side impact sensors, and internal electronic sensors with a predetermined value.

If the deceleration signal due to a frontal or side impact exceeds a predetermined value, the computer will initiate the deployment of the pretensioners and the deployment of the corresponding airbags.

If the vehicle"s battery ruptured during the crash, the voltage holding circuit in the ECU would still be able to activate the airbags for some time after the impact;

Hyundai Solaris security system design features

– frontal and side impact sensors that transmit acceleration information to the system control unit.

The force and direction of the impact in a traffic accident is determined by the electronic control unit of the passive safety system using impact sensors.

According to the signals from the sensors, the control unit activates the airbags and front seat belt pretensioners.

Front impact sensors are located on the side members of the car body behind the front bumper

Side impact sensors are mounted on the B-pillar on the inside behind the pillar trims;

Side impact sensor shown, located on the left side of the vehicle. Another sensor is located on the right side in a similar way.

Side impact sensors are installed on cars with side airbags and inflatable curtains in the variant.

Hyundai Solaris Safety System Design Features

- seat belts. Upon impact of a certain force, the ECU, having received signals from the impact sensors, increases the tension of the belts before activating the airbags, issuing a command to the pyrotechnic elements of the pretensioners.

The latter provide a timely response to an emergency deceleration of the car, pulling the driver and front passenger to the seatbacks, preventing them from further moving forward by inertia and getting injured from a deployed airbag;

The seat belt pretensioner mechanism always deploys before the airbag.

Hyundai Solaris Security Design Features

- head restraints mounted on the backs of the driver"s and front passenger"s seats of cars of all trim levels and on the back of the rear seat.

Head restraints prevent occupants from getting hurt in the neck in the event of a severe rear impact or airbag deployment.

The front and rear seat head restraints can be adjusted in height by pressing the lock and moving the head restraint up or down to the desired height

The optimal position of the head restraint is when its upper edge is flush with the top of the head.

For very tall people, raise the headrest to its highest position; for very short people, lower the headrest to its lowest position.

- signaling devices of the passive safety system:

Car safety system design features Hyundai SolarisDesign features car security system Hyundai Solaris

- malfunction indicator in the airbag system;

If the signaling device lights up, immediately contact a specialized car service. In addition to the possible failure in an emergency, the airbag can deploy unexpectedly while driving and lead to serious consequences.

- driver"s seat belt indicator.
