Basic Parking Brake Function With The EMF

Situation: "Ignition ON" and the engine is not running  . When the vehicle is stationary, the parking brake is released or applied by pressing the push button. The light in the instrument cluster is either not lit or is red. The lettering "PARK" is illuminated while the brake is released or applied. Pressing the button while the vehicle is rolling triggers the dynamic braking function.

Changing from the EMF to DSC:  When the EMF is applied and the engine is started, the system changes over to the service brakes using the DSC. The EMF is not released until  the service brakes are applied. The light is permanently red and the transfer is not indicated to the driver (transparent).

Changing from DSC to EMF:  When automatic hold is activated or  the ignition is switched "OFF" (even if automatic hold was not activated), the service brakes are released after  the changeover to the EMF takes place. If automatic hold was activated, the indicator light changes from green to red. If the service brakes are applied, they will be released after  the changeover to EMF. The indicator light will remain red during this changeover.
