 BY EXAMPLE: SOME MERCEDES MODELS CAN :  ADJUST SEAT BACK POSITION AND HEADRESTS  PRETENSION SEATBELTS AND RELEASE EXCESS TENSION  PREPARE OR APPLY THE BRAKES  SHUT OFF FUEL PUMP, TURN OFF ENGINE  DISCONNECT BATTERY AND ALTERNATOR  CLOSE WINDOWS OR SUNROOF  DEPLOY ROLL-BAR  RETRACT STEERING COLUMN  DEPLOY ONE OR MULTIPLE AIRBAGS (NEW LEXUS HAS 10 AIRBAGS!) N EW V EHICLE T ECHNOLOGY

HOW DO YOU RETRIEVE IT?  AIRBAG MODULE (THE BLACK BOX)  ON BOARD DATA (OBDII)  SELF DIAGNOSTIC; ERROR CODES  REMOVAL OF THE “COMPUTER OR MODULE” (FOR CRASHED VEHICLES)  DEALER PROPRIETARY SOFTWARE N EW V EHICLE T ECHNOLOGY

WHAT ARE ADVANTAGES … & DISADVANTAGES FOR YOU?  Good first impression (not subjective or emotional)  Very specific hard data (once confirmed)  Clarify situation  Easy to obtain…but also easy to misuse N EW V EHICLE T ECHNOLOGY
