The vehicle is equipped with a reversing light located on the right side of the rear bumper (on right hand drive versions, it is located on the left hand side).This is operated whenever reverse is engaged via a switch on the outside of the gear housing.The circuit for the reversing lights is supplied with the key ON (INT) and is protected by a special fuse in the junction unit under the dashboard.The signal that reverse gear has been engaged is managed by the Body Computer which sends this information, via the CAN, to the integrated radio-telephone-navigator node See E4091 CONNECTand to the parking control unit See E3090 PARKING SENSOR.
