Drive Away Release

When the Electric Park Brake (EPB) is applied, the drive away release releases the EPB when the accelerator pedal is pressed. This helps to provide a smooth drive away. This is done without the EPB switch being set to the release position. The drive away release is only active if either the driver door is closed, or if the driver seatbelt is buckled and in power mode 7.

The following factors determine the point at which the EPB control module releases the brakes:

• Tilt angle - From the longitudinal motion sensor in the Restraints Control Module (RCM).
• Engine torque - From the Powertrain Control Module (PCM).
• Throttle pedal applied - From the Accelerator pedal position (APP) sensor.
• Drive (D) or Reverse (R) selected - From the Transmission Control Module (TCM).

Drive away Release operation can be delayed by holding the EPB switch in the applied position, then releasing it back to its neutral position.
