242 STARTING AND OPERATING
If the parking brake is applied while the vehicle is
moving, a chime will sound to alert the driver. The chime
will sound up to 10 times, or until the vehicle has
returned to a stop.
Before leaving the vehicle, make sure that the parking
brake is set. To set the parking brake, pull up firmly on
the lever. Always move the shift lever into the PARK
position (automatic transaxle) or into the REVERSE po-
sition (manual transaxle). To release the parking brake,
apply the brake pedal, pull up slightly on the lever, then
press the button on the end of the lever and push the
lever fully down toward the floor.
NOTE: The parking brake lever will not release unless
the lever is pulled up slightly past its applied position.
Parking Brake
When parking on a hill, it is important to set the parking
brake before placing the shift lever into PARK, otherwise
the load on the automatic transaxle locking mechanism
may make it difficult to move the shift lever out of PARK.
