Car pass Card

Each vehicle has a car pass, which is issued to the customer on delivery of the vehicle along with the other papers.
For this, a card is used, similar to the conventional radio passes.

Note:

This car pass is an important document and must be treated with the same care as the vehicle papers. It
must not be kept in the vehicle. The customer must present the car pass for operations involving the
immobilizer or the engine control unit.
