Description & Operation

WARNING: Vehicle is equipped with Supplemental Inflatable Restraint (SIR) system. When servicing vehicle, use care to avoid accidental air bag deployment. SIR system-related components are located in various locations throughout interior of vehicle, depending on application. Do not use electrical test equipment on or near these circuits. If necessary, deactivate SIR system before servicing components. See AIR BAG SAFETY PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in AIR BAG RESTRAINT SYSTEMS article.

The Driving Position Memory System (DPMS) can memorize driver's seat position and power mirror positions for 2 different drivers by pressing the MEMO button, then either button No. 1 or 2 on DPMS switch after adjustments have been made. The DPMS switch is located in driver's door panel. Adjustments can also be made manually. Afterward, when vehicle is in PARK and driver's door is closed, return to memorized position by pressing either DPMS switch button No. 1 or 2.

Memory mirrors use a Hall-Effect type tilt sensor to transmit voltage changes caused by mirror movement. These voltages are stored in DPMS control unit memory, relative to memorized positions. With power mirror switch in the center OFF position, when vehicle is shifted into REVERSE, passenger side rear view mirror tilts downward to aid driver's rear view.

On driver's seat, 4 motors provide for front up/down, rear up/down, forward/back, and recline adjustment. See Fig 1 . Each motor includes a reed-switch sensor, which sends a pulse signal to DPMS control unit to indicate motor position.
