Parking Brake and Ignition Key Release
Warning: Do not operate the vehicle with the front brakes backed off or disconnected. Backing off or disconnecting the front brakes will not improve vehicle handling and may lead to loss of vehicle control, resulting in property damage or personal injury.
Before driving the vehicle, secure all loose items in the vehicle so that they will not fly forward during a full brake application.
Notice: Do not continually press down on the parking brake control valve (yellow knob) without pressing down on the service brake pedal. This will damage the safety interlock.
The service brakes and parking brakes have a safety interlock that prevents the unintentional release of the parking brake. These instructions need to be followed for the appropriately equipped vehicle to release the parking brake interlock.
- Turn the ignition key to the ON position.
- Depress the brake pedal.
- Push the parking brake control valve in.
