Fleetwood 1997 Discovery Owner's Manual page 63

The Allison MD-3060 (World Transmission) provides for
optimum retarding downshift operation when the Extarder
compression brake is selected. When the Extarder's dash
switch is turned ON and your foot is removed from the
throttle pedal, the transmission will immediately preselect a
lower gear. The gear preselected is usually second gear,
however, your vehicle may have been programmed for either
third or fourth. The transmission then starts to downshift
through the gears to reach the preselect gear. Downshifting
occurs at a higher speed than is usual when the Extarder is not
turned on. This allows the Extarder compression brake to
provide the maximum retarding power.
Operation on Wet or Icy Roads
It is recommended that on wet and slippelY or icy roads that
the Extarder not be left in the automatic mode. The ON/OFF
switch should be in the OFF position.
Operation of the Extarder compression brake is recommended
only when you have good traction with the road surface.
Operation on wet roads should be undertaken with extreme
care and at the driver's discretion.
Your motor home is equipped with air brakes. Air brakes are
more sensitive than hydraulic brakes. Practice stopping in a
safe, unobstructed area until you get the feel of the brake
pedal.
The green needle on the air pressure gauge indicates front
brake system air pressure. The red needle indicates rear brake
system air pressure. Please note that the vehicle will not move
until air pressure is sufficient to release the brake safety
springs. A dash indicator will light and a buzzer will sound
until the proper operating pressure is reached.
