Driving BRAKE-SHIFT INTERLOCK The vehicle is equipped with a brake-shift interlock feature that prevents the gearshift lever from being moved from P (Park) unless the brake pedal is pressed. If you cannot move the gearshift lever out of P (Park) with the ignition in the on position and the brake pedal pressed, it is possible that a fuse has blown or the vehicle's brake lamps are not operating properly. Refer to Fuses and relays in the Roadside Emergencies chapter. If the fuse is not blown and the brake lamps are working properly, the following procedure will allow you to move the gearshift lever from P (Park): 1. Apply the parking brake, and turn the ignition to the on position. 2. Remove the lower trim panel under the steering column. Make sure to not disturb the wires on the electrical connector. 3. Locate the brake-shift interlock solenoid underneath the steering column. 4. Pull back on the solenoid, and at the same time, shift the transmission into N (Neutral). 5. Start the vehicle. See your authorized dealer as soon as possible if this procedure is used. WARNING: Do not drive your vehicle until you verify that the brake lamps are working. WARNING: Always set the parking brake fully and make sure the gearshift is latched in P (Park). Turn the ignition to the lock position and remove the key whenever you leave your vehicle. WARNING: If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. See your authorized dealer. 209 2010 Econoline (eco) Owners Guide, 3rd Printing USA (fus)
