yellowblue Automatic Transaxle Operation If you cannot shift out of PARK (P), ease pressure on the shift lever -- push the shift lever all the way into PARK (P) as you maintain brake application. Then move the shift lever into the gear you wish. See "Shifting Out of PARK (P)" in this section. CAUTION: Maximum engine speed is limited 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 gear position 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 PARK (P) before starting the engine. Your vehicle has a Brake-Transaxle Shift Interlock (BTSI). You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition key is in RUN. As you step on the brake pedal, while in PARK (P), you may hear a click from the solenoid of the BTSI. This ensures that the BTSI is operating properly. It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Don't leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle won't move, even when you're on fairly level ground, always set your parking brake and move the shift lever to PARK (P). See "Shifting Into PARK (P)" in the Index. If you're pulling a trailer, see "Towing a Trailer" in the Index. 2-43
