Adjustable Pedals System

The Adjustable Pedals are designed to enable the fore and aft repositioning of the brake and accelerator pedals. This results in improved ergonomics in relation to the steering wheel for taller and shorter drivers. Being able to adjust the pedal positions also allows the driver to set steering wheel tilt and seat positions to the most comfortable position available. The positions can be adjusted without compromising safety or comfort in actuating the pedals. Repositioning the pedals does not change the effort required for actuation. Changing of pedal position is accomplished by means of a motor.

Operating the adjustable pedal switch activates the pedal drive motor. The pedal drive motor changes the position of the brake and accelerator pedals. The pedal can move rearward or forward. The pedals are moved to a position that is most comfortable for the driver. The accelerator and brake pedals are moved at the same rate to ensure synchronization. Neither the motor nor mechanisms are subject to mechanical stress of brake or accelerator application.

The adjustable pedals feature is available on a non-memory/memory-equipped vehicle. The non-memory system consists of a mechanical switch that allows pedal travel adjustment. The IPM controls the Fused B+ circuit voltage to the adjustable pedals switch through the adjustable pedals relay. The circuit opens when the IPM detects an active cruise control state or when the vehicle is in reverse. The adjustable pedals control switch is located on the right side steering column shroud. The switch is hardwired directly to the adjustable pedals motor. When the operator actuates the switch to adjust the pedals, voltage is applied to the adjustable pedals motor allowing adjustment. The memory system, known as the Memory Seat Mirror Adjustable Pedal Module (MSMAPM), is located under the driver's seat and controls the adjustable pedals. The adjustable pedals control switch is located on the right side steering column shroud. The switch is hardwired directly to the MSMAPM. When the operator actuates the switch to adjust the pedals, the MSMAPM controls the adjustable pedals motor movement with input from the adjustable pedals sensor. This sensor allows pedal adjustment and memory functions to be recalled from the driver door mounted memory buttons or the RKE transmitters. The adjustable pedals will not operate when in an active cruise control state or when the vehicle is in reverse.
