Releasing Spring Manually
WARNINGS
Do not attempt to disassemble the
parking brake air chamber under any
circumstances as this may cause
serious injury.
Block the wheels to help prevent the
vehicle from moving.
Unexpected and possibly sudden
vehicle movement may occur if you
do not take these precautions.
If you release hydraulic pressure from the
spring brake chamber, the power spring
applies the brake. If the hydraulic pressure
can be re-established, you must release
the spring brake in order to move your
vehicle.
Air Brakes
(If Equipped)
WARNING
This control is for parking only. Do
not leave the vehicle unattended
after setting the parking brake
without placing the transmission in park
(P). We recommend using wheel chocks
for hilly or off-road circumstances.
If the service brakes fail to operate while
your vehicle is moving, you can make an
emergency stop with the parking brake.
Since the parking brake only applies
stopping power to the rear wheels, your
vehicle’s stopping distance greatly
increases and the handling of your vehicle
is adversely affected. Make repairs
immediately to an inoperative air brake
system circuit.

When your vehicle is stationary, keep
the brake pedal fully pressed when

instruction could result in personal injury,
death or property damage.

prepare to drive the vehicle.
Note:
The parking brake does not disengage
unless sufficient system air pressure is
available.

Press and hold the service brake pedal
while the engine is running.
2. Select the appropriate drive gear.
3. Push and hold the yellow
dash-mounted parking brake knob until
