Automatic Transaxle Operation Your automatic transaxle has a shift lever on the steering column or on the console between the seats. {CAUTION: It can be 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. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, use the steps that follow. If you are pulling a trailer, see Towing a Trailer on page 286. Make sure the shift lever is fully in PARK (P) before starting the engine. Your vehicle has an automatic transaxle shift lock control system. You must fully apply your regular brakes first and then press the shift lever button before you can shift from PARK (P) while the ignition is in RUN. If you cannot shift out of PARK (P), ease pressure on the shift lever and push the shift lever all the way into PARK (P) as you maintain brake application. Then press the shift lever button and move the shift lever into another gear. See Shifting Out of Park (P) on page 123. 117 There is a display, located on the instrument panel cluster that will indicate the gear the vehicle is in. Maximum engine speed is limited on automatic transaxle vehicles while you are in PARK (P) or NEUTRAL (N) to protect driveline components from improper operation. There are several different positions for the shift lever. PARK (P): This position locks your front wheels. It is the best position to use when the engine is started because your vehicle cannot move easily.
