What action occurs when the driver activates the accelerator pedal with the electronic parking brake engaged?

When the driver activates the accelerator pedal with the electronic parking brake engaged, the system is designed to automatically release the electronic parking brake. This is a safety and convenience feature that prevents the vehicle from stalling and allows for a smooth transition when starting to drive. The automatic release ensures that the driver can move forward without needing to manually disengage the brake, enhancing the overall driving experience.

The other options do not accurately describe what happens in this scenario. While a warning tone might indicate that the parking brake is still engaged when the accelerator is pressed, it doesn't take precedence over the designed feature of automatically releasing the brake. Engaging the parking assist feature would require separate activation and is not tied to the accelerator pedal function in this context. Increasing engine RPMs would occur as a natural response to pressing the accelerator, but it isn't the primary action prompted by the situation described.
