Park Brake Input
WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
The Daytime Running Lamps (DRL) control module will not operate the headlamps or exterior lamps if the park brake is applied before the ignition switch is turned to the RUN position. This allows the operator to start the vehicle and keep the headlamps off, as long as the park brake is applied. The DRL module will activate the headlamps when the park brake is released with the ignition switch in the RUN position. This feature will only function when the park brake is applied before the ignition switch is turned to the RUN position. The headlamps will not turn off if the park brake is applied after the ignition switch is turned to the RUN position.
