Renaul

I have problems with the car when I start it, I turn on the light of Airb

What kind of reindeer do you have? Model and brand, diesel or bencinero?, now the airbag light usually passes mainly in the Peugeot, anyway it does not probate any problem, it is only the light, the best way to change batteries to these cars is with the engine running, so no light turns on, the service can be because you have to perform some intended maintenance of the house, that can be eliminated, but I do not know how in your vehicle It is done by opening the contact 20 seconds you close it 15 and then you open it 20 and give the boot to try wants to work with the Renaul, that of the airbag is the problem or take it to the house or get a workshop with Scanner and that can enter the system.
