Warning! Before working on the security system, to prevent injury in case of unauthorized activation of the system, disconnect the battery. After finishing the work, make sure that there is no one in the car when connecting the battery. Open the door and turn on the ignition from outside the car.
Warning! Do not expose the system to temperatures above 90°C. After removing the airbag, store it properly to prevent unauthorized deployment.
Caution! Do not allow solvents or cleaning fluids to come into contact with the airbag units. The units may only be cleaned with a soft cloth.
Caution! The airbag unit and control unit are sensitive to impact. If the unit has been dropped or hit, it must be replaced.
Attention! Before starting welding work using electric welding, disconnect the wiring connector from the system control unit.
Driver and passenger airbags are standard equipment in some models and optional in some models. On models equipped with airbags, the driver's airbag is installed in the middle of the steering wheel. The passenger airbag is installed in the dashboard above the glove box. The system includes airbag units (together with gas generators). impact sensor, control unit and indicator on the instrument panel. Some models are also equipped with side airbags and seat belt tensioners, which are combined into a common system with the front airbags. The complexity of removal and installation is beyond the scope of this Manual.
The system is triggered by a frontal impact of a certain force, depending on the direction of the impact. In a few milliseconds, the airbag inflates, forming a safety bubble between the driver and the steering wheel and (if installed) passenger and the front panel. This significantly reduces the risk of injury to the driver and passenger. The airbag deflates almost immediately through the side openings. The control unit also causes the seat belt pretensioners to operate simultaneously with the airbags.
When the ignition is turned on, the control unit performs a self-test that lasts about three seconds, during which the indicator lights up on the instrument panel. When the test is complete, the indicator goes out. If the indicator does not light up, lights up later, lights up for more than three seconds, or lights up while the car is moving, then there is a malfunction in the system. In this case, the car should be immediately presented to specialists at the dealership car service.
