Driving TRACTION-LOK™ AXLE (IF EQUIPPED) This axle provides added traction on slippery surfaces, particularly when one wheel is on a poor traction surface. Under normal conditions, the Traction-Lok™ axle functions like a standard rear axle. Extended use of other than the manufacturer's specified size tires on a Traction-Lok™ rear axle could result in a permanent reduction in effectiveness. This loss of effectiveness does not affect normal driving and should not be noticeable to the driver. AUTOMATIC TRANSMISSION OPERATION Brake-shift interlock - column-shift transmission This vehicle is equipped with a brake-shift interlock feature that prevents the gearshift lever from being moved from P (Park) when the ignition is in the ON position unless brake pedal is depressed. If you cannot move the gearshift lever out of P (Park) with ignition in the ON position and the brake pedal depressed, it is possible that a fuse has blown or the vehicle's brakelamps are not operating properly. Refer to Fuses and relays in the Roadside Emergencies chapter. If the fuse is not blown, perform the following procedure: 1. Apply the parking brake, turn the ignition to 2 (ACC). 2. Locate the access plug on the underside of the steering column cover. 3. Remove the access plug using a flat head screwdriver. Insert the screwdriver into the access hole nearest the steering wheel. Then push and hold the override button using a flat head screwdriver. Apply the brake pedal and shift the transmission into N (Neutral) while continuing to depress the override button. 4. Reinstall the access plug cover, start the vehicle and release the parking brake. 185 2008 Grand Marquis (grn) Owners Guide (post-2002-fmt) USA (fus)
