Brakes and Traction Control: Description and Operation

Brake System
The power brake booster may be the vacuum type or the Hydro-Boost(R) type.

The braking system is a front to rear split hydraulic system.

The front wheel brakes utilize a dual piston brake caliper and disc brake system.

The rear brakes utilize a dual piston brake caliper and disc brake system.

The parking brake system is a mechanical system that activates a shoe-and-drum system within the rear disc brake rotor.

The anti-lock brake system is a 3-channel Four-Wheel (4WABS).

Adjustable Pedals
The vehicle is equipped with an adjustable brake and accelerator pedal system. Using the adjustable pedal switch, the driver can adjust the brake and accelerator pedals for a more comfortable driving position.

Adjustable Pedal Operation
The adjustable pedals are operational with the ignition switch ON or OFF. The pedals can be adjusted forward or rearward using the adjustable pedal switch.

Memory Adjustable Pedal Operation (Limited Only)
The adjustable pedals with memory feature can be controlled by using the memory switches or the remote transmitter. The power driver seat positions are also stored and recalled with the power adjustable pedal positions. The system can store 3 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.
^ 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
- Memory SET switch.

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

The DSM constantly monitors the systems under its control and reports a concern in the form of Diagnostic Trouble Codes (DTC's). A DTC can be retrieved with the diagnostic tool through the communications link.

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 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 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.
^ A remote transmitter can be used to recall previously set memory positions. The remote transmitters are manufactured with an assigned personality number (1 or 2) and are so designated on the back of the remote transmitter case. The remote transmitter assigned to personality 1 is capable of only recalling memory position 1
1. Similarly, the remote transmitters assigned with personalities 1 and 2 can recall memory positions 1 and 2 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.
