CAUTION: LOSS OF VEHICLE CONTROL
To avoid injury from loss of vehicle control, do not activate the
Engine Brake system under the following conditions:
• On wet or slippery pavement, unless the vehicle is equipped
with ABS (anti-lock braking system) and you have had prior
experience driving under these conditions.
• When driving without a trailer (bobtailing) or pulling an empty
trailer.
• If the tractor drive wheels begin to lock or there is fishtail
motion after the Engine Brake is activated, deactivate the brake
system immediately if this occurs.
NOTE:
On single trailers or combinations, a light air application of the trailer
brakes may be desirable to help keep the trailer stretched out. Follow the
manufacturer's recommended operating procedure when using your trailer
brakes.
2. If the tractor drive wheels begin to lock or there is fishtail motion after the
Engine Brake is activated, deactivate the brake system immediately if this
occurs.
3. However, if the tractor drive wheels begin to lock or there is a fishtail
motion, turn the engine brake system OFF immediately and do not activate it
until road conditions improve.
4. Check your progressive braking switch often for proper position
(LOW/MED/HIGH), since road conditions can change quickly. Never skip a
step when operating the progressive braking system. Always go from OFF to
LOW and then to a higher position.
