Leaving Your Vehicle With the Engine
Running (Automatic Transaxle Models
Only)
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you've moved the shift lever into the PARK (P)
position, hold the regular brake pedal down. Then, see if
you can move the shift lever away from PARK (P)
without first pushing the button.
If you can, it means that the shift lever wasn't fully
locked into PARK (P).
