Operation
Power Parking Brake System
WARNING
To prevent property damage, personal injury, and
/ or death, when parking your vehicle, always
use the parking brake. When parking on a grade,
install wheel chocks and turn front wheels to
keep the vehicle from rolling into the traveled
portion of the roadway. Failure to follow these
procedures could cause an unattended vehicle
to move.
WARNING
To prevent property damage, personal injury,
and / or death, under no circumstances should
the parking brake chamber be disassembled.
Disassembly will release a powerful spring.
The purpose of the parking brake is to hold the vehicle in the
parked position. It should NOT be used to brake the vehicle
during normal driving. It may be used to assist in making an
emergency stop in the event of service brake failure.
The Powered Parking Brake is controlled by the parking brake
instrument panel switch.
The switch has three positions:
apply (out), neutral (center), and release (in). The switch is
spring-loaded to return to the neutral (center) position after
being pushed or pulled. There is no visual indication at the knob
that the parking brake is applied or released. Always observe
the gauge Instrument Panel Gauge Cluster PARKING BRAKE
indicator to determine if the parking brake is applied or released.
The parking brake will be automatically applied when the ignition
switch is moved to the OFF position and cannot be released until
the ignition switch is turned to the ON position.
To Manually Apply the Powered Parking Brake
1. Bring the vehicle to a complete stop, using your brake
pedal.
2. Make sure that the engine is at low idle.
3. With your foot still firmly on brake pedal, place
transmission in P (Park) or N (Neutral) position.
4. Pull and HOLD the parking brake control knob until the
PARKING BRAKE indicator, in the Instrument Panel
Gauge Cluster, illuminates. Then release the parking
brake control knob (the knob will return to its normal
resting position).
An (Optional) feature provides for the Parking Brake to
automatically be applied (Auto-Apply) when the shifter is
moved to the “PB” (Parking Brake) or “P” (Park) position.
