TOYOTA IS RECALLING CERTAIN MODEL YEAR 2008 HIGHLANDER, HIGHLANDER HYBRID, AND MODEL YEAR 2007-2008 RAV4 VEHICLES. IN THE CURTAIN SHIELD AIRBAG (CSA) SYSTEM, THERE ARE TWO SENSORS IN THE AIRBAG SENSOR ASSEMBLY WHICH ARE DESIGNED TO DETECT VEHICLE ROLL ANGLE. IF ONE OF THESE SENSORS MALFUNCTIONS, THE AIRBAG WARNING LIGHT (MALFUNCTION INDICATOR LIGHT: MIL) WILL ILLUMINATE AND THE ROLL DETECTION SYSTEM WILL BE SUSPENDED; HOWEVER, THE AIRBAG CSA REMAINS AVAILABLE IN THE EVENT OF A SIDE CRASH. IF BOTH SENSORS FAIL NEARLY SIMULTANEOUSLY AFTER INITIAL AIRBAG SYSTEM CHECK, THE CSA AND THE SEAT BELT PRETENSIONER COULD BE INADVERTENTLY ACTIVATED.
