Parking Brake; Leveling Controls - Holiday Rambler Imperial 2008 Owner's Manual

The Mode button enables a secondary
shift point to be selected. This is
commonly referred to as Economy
mode. Economy mode affects the upshift
schedule 3-4, 4-5, 5-6 and downshift
schedule 6-5, 5-4, 4-3. During highway
driving, with the cruise control set
between 55 and 65 m.p.h., setting the
transmission to economy mode will
eliminate about 99% of transmission
downshifts from sixth to fi fth when
incurring a slight incline or overpass.
DO NOT use economy mode while traveling in
mountain terrain. The lower RPM shift schedule
will reduce the fl ow of antifreeze, lubricating
oil and air fl ow 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 terrain. Frequent shifting
will occur and increase 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 6-3. 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 gear. This is
only a reference point indicating
the transmission will automatically
downshift to second gear when
auxiliary braking device is engaged.

Parking Brake

The parking brake system
is activated by pulling the
push-pull control knob
located on the dash to the
left of the steering wheel.
When the knob is pushed,
the brake is released. Prior
to driving, allow time for the
air compressor to build up
suffi cient air to shut off the air
warning lamp.
WARNING:
It is possible for the parking brake to
accidentally release if the air system
is charged. It is advised to fabricate a
device to be placed under the parking
brake handle to prevent children or pets
from releasing the brake when parked.
A wooden clothespin clasped to the shaft
is suitable.
