Brakes and Traction Control: Description and Operation

Brake System
The brake system has the following components:
^ a vacuum-assisted power braking system.
^ a front-to-rear split hydraulic system.
^ front disc brakes utilizing a dual piston brake caliper and disc system.
^ rear disc brakes utilizing 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.
^ adjustable pedals.
^ adjustable pedals with memory.
^ fixed pedals.

This vehicle is equipped with an electronic throttle control.

Adjustable Pedals
The vehicle is equipped with an adjustable brake and accelerator pedal system. 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 ON or OFF. The pedals can be adjusted forward or rearward using the adjustable pedal switch.

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

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

Memory Adjustable Pedal Operation
The adjustable pedals with memory feature can be controlled by using the memory switches or the remote keyless entry transmitter. The outside rearview mirror and power driver seat positions are also stored and recalled with the power adjustable pedal positions. The system can store three memory settings.

Programming Adjustable Pedal Positions
Programming adjustable pedal positions can be accomplished by doing the following:
^ An adjustable pedal position can be stored at any time. To store the adjustable pedal position to memory, the driver must move the pedals to the preferred position using the adjustable pedal switch. The driver must then press the memory SET switch, activating the memory SET switch light emitting diode (LED). Within 5 seconds (before the LED goes out) the driver must select memory position 1, 2, or 3.
^ If no memory switch input is received within the 5 second time limit, the operation is aborted and the memory SET switch LED is turned OFF. If one of the following inputs is received during the 5 second programming limit, the operation is aborted and the memory SET switch LED is turned OFF:
- Adjustable pedal switch
- Power driver seat switch
- Exterior mirror control switch
- Memory SET switch.

Recalling a Stored Adjustable Pedal Position
Once the driver has stored a preferred adjustable pedal position, the driver can recall the setting by pressing the corresponding memory switch, or by using a programmed remote keyless entry transmitter. Recalling a stored adjustable pedal position can be accomplished by doing the following:
^ The driver can recall a preferred adjustable pedal position by pressing one or both of the memory recall switches. Pressing memory switch 1 will initiate a recall of the adjustable pedal position stored in memory no. 1 Pressing memory switch 2 will initiate a recall of the adjustable pedal position stored in memory no. 2. Pressing both memory no. 1 and memory switch 2 will initiate a recall of the adjustable pedal position stored in memory no. 3.
^ A remote transmitter can be used to recall previously set memory positions. The remote keyless entry transmitters are manufactured with an assigned personality number (1, 2, or 3) and are so designated on the back of the remote keyless entry transmitter case. The remote transmitter assigned with personality 1 is capable of only recalling memory position 1. Similarly, the remote transmitters assigned with personalities 1, 2, and 3 can recall memory positions 1, 2, and 3 respectively.
^ Memory recall occurs when the UNLOCK switch is pressed on the remote transmitters. A second press of the UNLOCK switch, which unlocks the passenger doors, does not initiate a memory recall.
^ A memory recall in progress does not prohibit the initiation of another memory recall; the most recently requested memory recall will be executed.
