The Power Park Brake is controlled by the park brake dash-mounted,
yellow knob-type switch. The switch has three positions: apply (out),
neutral (central), and release (in). The switch is spring-loaded to return
to the neutral (central) position after being pushed or pulled.
There is no visual indication at the knob that the park brake is
applied or released; check the instrument cluster. If the light is
illuminated, the parking brake is applied.
Applying the Parking Brake
Pull the yellow, dash-mounted parking brake knob. The parking brake
light illuminates indicating that the parking brake has been successfully
set.
Note:
If the light blinks and a warning chime sounds when the control
knob is pulled, the parking brake is not functioning properly. Seek
immediate service from your dealer. See
Parking brake warning
system
in this section.
