Principles of Operation

Principles of Operation

Power Brakes
Pressing the brake pedal pushes a rod into the brake booster which, through the use of vacuum, boosts the force of the rod, transmitting the force into the master cylinder. This action produces hydraulic pressure in the master cylinder. Hydraulic pressure is transmitted through the master cylinder by brake fluid, through the brake lines, to the individual brake calipers. The brake calipers use hydraulic pressure to apply the pads. The application of the brake pads against the friction surfaces of the brake discs causes the rotation of the wheels to slow or stop, depending on how much brake pressure is applied. The parking brakes perform the same function except that they are mechanically actuated by a cable that connects only to the rear brake calipers.

Programming Adjustable Pedal Positions
An adjustable pedal position can be stored at any time.

Programming adjustable pedal positions can be accomplished by the following:
^ To store the adjustable pedal position to memory, move the pedals to the preferred position using the adjustable pedal switch. Press the memory SET switch, activating the memory SET switch light emitting diode (LED). Within 5 seconds (before the LED goes out) select memory position 1 or 2.
^ 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

To program the remote keyless entry (RKE) transmitter, refer to Locks.

Recalling a Stored Adjustable Pedal Position
Once a preferred adjustable pedal position is stored, it is recalled by pressing the corresponding memory switch, or by using a programmed RKE transmitter.
^ The driver can recall a preferred adjustable pedal position by pressing one of the memory recall switches. Pressing memory switch 1 initiates a recall of the adjustable pedal position stored in memory No. 1. Pressing memory switch 2 initiates 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 with personality 1 is capable of only recalling memory position 1. Similarly, the remote transmitter assigned with personality 2 can 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 is executed.
