Parking Brake - Holiday Navigator 2003 Owner's Manual

In city driving, with the transmission set to economy mode, the transmis-
sion will upshift approximately 200 RPM sooner using less fuel with reduced
engine noise. Do Not use economy mode while traveling in mountain terrain.
The lower RPM shift schedule will reduce the flow of antifreeze, lubricating
oil and air flow through the radiator resulting in increased transmission and
engine temperature.
CAUTION: Do not use the economy mode in heavy stop and
go traffic or mountainous terrains. Frequent shifting occurs
when in economy mode while using heavy throttle, increasing
transmission fluid temperature. Exit economy mode until
road conditions improve.
NOTE: When the Auxiliary Braking device is used, the
display will change to a default reading of 2 or 3. This setting
is pre-selected at the factory and can only be altered by an
authorized Allison Service center. The transmission is not
actually in second or third gear. This is only a reference point
so the transmission will optimize engine braking efficiency.
The parking brake system is activated when the push-pull control knob
(located on the driver's left console panel) is pulled. When the knob is pushed,
the brake is released. Prior to driving, allow time for the air compressor to
build up sufficient air to shut off the air warning lamp.
WARNING: If the air tank is not dumped, there is the
possibility of an accidental release of the parking brake.
Traveling with small children and/or pets may require a small
block to be fabricated to prevent accidental release. The block
should be placed under the knob and rested on the dash
panel. A wooden clothes pin clasped at the base of the shaft
will work.
