I mean the way the switch was designed which affects the perceived quality. If only half the length of the key is needed and allowed to turn the switch, I wonder if someone can insert a different i20's key or even a Skoda key and get the switch to turn.
Until an expert throws light, I will explain that the weight sensor detects if a person or object of weight either above or below a certain threshold is placed on the seat. I once drove an American Corolla which had a front passenger weight sensor. This sensor was linked to the front passenger airbag. If nobody was seated, the "passenger airbag off" sign would illuminate. If someone of sufficient weight was seated, the "passenger airbag on" sign would illuminate. The weight sensor takes care of airbag management automatically on U.S. market auto's.
Therefore, in a frontal impact, if nobody is seated on that seat, the airbag would not fire and money would be saved. If an adult was seated, the airbag would fire and a life would potentially be saved. Also, if a child (with or without carseat) below the weight threshold was placed on that seat, the airbag would not fire, potentially saving a life. In America, one needs government permission to obtain a manual airbag switch for the front passenger seat and this permission is given only for auto's that do not have a proper backseat for children. India has no such laws yet so Hyundai has decided to install that switch as a feature. The problem is since the Indian market i20's weight sensor is only linked to the seatbelt reminder and cannot overrule the airbag switch, when an adult sits on that seat and the driver has forgotten to switch on the airbag and nobody has noticed the passenger airbag-off warning light, the front passenger can be injured during a frontal impact. This injury could lead to a lawsuit which is why the average American usually is not allowed to have a manual airbag override switch. The weight sensor is linked to the airbag and the decision to arm or disarm the airbag is automatic.
The Indian market i20's weight sensor does not seem to take care of airbag management automatically due to the presence of the manual switch, unless I'm mistaken. The weight sensor only reminds the passenger to wear a seatbelt. If someone has read either the i20's owner manual or the service technical manual, we can confirm or reject my presumption.

My question is since the i20 has a backseat for children, why did Hyundai India install this airbag override switch and also install a weight sensor that does not communicate with the airbag? Why not give us the automatic system like they did for the Americans? As it is, the average customer, whether Indian or American, is almost clueless about auto safety and should not be trusted with important decisions such as this. Hyundai India should make the i20's system automatic and save people the trouble and danger of forgetting to turn on/off the airbag for the appropriate passenger. After all, it does not cost anything, does it? In fact, Hyundai India would save money by not installing that switch and front seat passengers would be safer if the decision to arm or disarm the airbag was automatic.
I cannot think of a situation where you would want your adult or child front passenger to sit on the front seat, yet not have the airbag turned on or off respectively unless you purposely wanted to put them in harm's way.
I hope I am completely wrong in my presumption. If not, someone in charge of safety has screwed up at Hyundai India.
