WARNING
Using the trailer hand brake or air
brakes to hold a parked vehicle is dan-
gerous. Because they work with air
pressure, these brakes could come
loose. Your vehicle could roll, causing
an accident involving death or person-
al injury. Always set the parking
brakes. Never rely on the trailer hand
brake or truck air brakes to hold a
parked vehicle.
1. Set the parking brake before
leaving the driver’s seat. To hold
your vehicle while it is parked, don’t
rely on:
• Air Brakes
• Hand Control Valve for Trailer
Brakes
• Engine Compression
2. If you are parked on a steep grade,
block the wheels.
3. Drain water from the air reservoirs.
While the engine and air supply
system are still warm, drain
moisture from the air reservoirs.
Open the reservoir drains just
enough to drain the moisture. Don’t
deplete the entire air supply. Be
sure to close the drains before
leaving the vehicle.
4. Secure the vehicle. Close all the
windows and lock all the doors.
