See "Shifting Into PARK (P)" in the Index. If you're pulling a trailer, see "Towing a Trailer" in the Index. Your automatic transaxle may have a shift lever on the steering column or on the console between the seats. Maximum engine speedis limited on automatic transaxle vehicles when you're in PARK (P) or NEUTRAL (N) to protect driveline components from improper operation. There are several different positions for your shift lever. PARK (P): This locks your front wheels. It's the best position to use when you start your engine because your vehicle can't move easily.
