Brakes and Traction Control: Description and Operation

Brake System
The vehicle is equipped with a vacuum-assisted power braking system.

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 single 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 brake disc.

A 4-wheel anti-lock brake system (4WABS) with traction control is standard equipment.

Adjustable Pedals
The vehicle is equipped with an adjustable brake and accelerator pedal system. Using the adjustable pedal switch, located on the LH side of 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 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 adjustable pedals, only when the vehicle is equipped with the programmable/recall memory option (excluding Executive Series models).

NOTE: DSM diagnostics are compatible with the Worldwide Diagnostic System (WDS). The DSM incorporates multiple functions into one module and offers diagnostics to easily locate and repair concerns affecting the subsystems that it controls.

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 WDS or equivalent through the communications link.

Memory Adjustable Pedal Operation
The adjustable pedals with memory feature can be controlled by using the memory switches or the remote 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 2 memory settings.

Programming Adjustable Pedal Positions
Programming adjustable pedal positions can be accomplished with these steps:
^ 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 a memory position. Memory No. 1 is selected by pressing the 1 switch. Memory No. 2 is selected by pressing the 2 switch.
^ 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 these 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
- Power outside rearview mirrors 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 transmitter. Recalling a stored adjustable pedal position can be accomplished by performing these steps:
^ The driver can recall a preferred adjustable pedal position by pressing either 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 transmitter assigned with personality 1 is capable of only recalling memory position 1. Similarly, the remote transmitter assigned with personality 2 can only recall memory positions 2.
^ 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.
