Cold Weather Use - NewMar Scottsdale Class A 2006 Owner's Manual

Notice
If water is allowed to accumulate, some stain marks on the reflective
surfaces may appear, damaging the surface.
The headlamp seals should not be directly sprayed with high pressure
(home or industrial) wash systems..

Cold Weather Use

Although great care has been taken to build a well-insulated unit, recreational
vehicles are not intended for extended use in subfreezing weather without
special precautions.
When the temperature drops below freezing, the furnace must be turned on to
keep the unit warm. Continued use in cold weather will require the unit to be
winterized.
