^ Front brake discs using a dual piston brake caliper and disc system
^ Rear brake discs using a single piston brake caliper and disc system
^ A mechanical parking brake system that activates a drum-in hat system within the rear brake disc
^ A 4-wheel anti-lock brake system (4WABS) or roll stability control (RSC).
^ Adjustable pedals (if equipped)
^ Fixed pedals

Adjustable Pedals
Using the adjustable pedal switch located on the instrument panel, the driver can adjust the brake and accelerator pedals for a more comfortable driving position.

Adjustable Pedal Operation
The adjustable pedals with or without memory feature are operational with the ignition switch in the ON or OFF position. The pedals are adjusted forward or rearward using the adjustable pedal switch.

Driver Seat Module (DSM)
The DSM controls the memory adjustable pedals.

The DSM constantly monitors the systems under its control and records concerns in the form of diagnostic trouble codes (DTCs). A DTC can be retrieved with the diagnostic tool through the data link connector (DLC).

Memory Adjustable Pedal Operation
The adjustable pedals with memory feature is controlled by using the memory switches or the remote keyless entry (RKE) transmitter. The exterior mirror and power driver seat positions are also stored and recalled with the power adjustable pedal positions. The system can store 3 memory settings.
