I PARK R NIB3 2 1 There are several different positions for your shift lever. P (Park) This locks your front wheels. It's the best position to use when you start your engine because your vehicle can't move easily. Ensure the shift lever is fully in "F'" (Park) range before starting the engine. Your Buick has a brake-transaxle shift interlock. You have to fully apply your regular brakes before you can shift from "P" (Park) when the ignition key is in the "Run" position. If you cannot shift out of "P" (Park), ease pressure on the shift lever and push the shift lever all the way into " P ' (Park) asyou maintain brake application. Then move the shift lever into the gear you wish. See "Shifting Out of 'P' (Park)" in this part. 78
