CARE OF THE CONVERTIBLE BACK WINDOW
The back curtain on the Convertible Coupe is provided with pliable
plastic window which is of large size to allow ample visibility at the
rear of the Convertible Top. The plastic material at this location
makes possible a larger window than can be utilized if glass were
used. Due to the texture of the plastic window, it is susceptible to
scratches and abrasions; caution must be used in its cleaning and care.
1. When removing road dust, use a soft cotton cloth moistened with
water and wipe cross-wise of the window.
2. To clean the back window, use cold or tepid (not hot) water and
a mild, neutral soap suds. After washing, rinse with clear water
and wipe with a slightly moistened clean soft cloth.
CAUTION: Never use solvents such as alcohol or volatile cleaning agents
on the plastic window. These liquids may have a deteriorating effect on
the plastic and, if spilled, may spot the painted finish on the rear body
panels directly below the rear window.
3. In removing frost, snow, or ice from the plastic back window
DO NOT USE A SCRAPER. In an emergency, warm water may
be used. Use care that this warm water does not contact the
actual glass windows or windshield.
CARPET FLOOR COVERINGS
Carpets are either cemented or tacked down securely in place and
should not be removed unless it is definitely necessary to do so. If
the carpet must be removed, it should not be forcibly pulled loose;
this may cause the nap to pull through the warp of the carpet and
ruin its appearance. A corner of the carpet should be turned back,
and a wide-bladed putty knife or similar tool should be used to
separate the carpet from its cemented foundation.
To clean these floor coverings, first, brush thoroughly. If soil remains,
use a volatile type cleaner. Repeat for heavily embedded stains.
Extreme care should be taken to make certain that carpets are not
"soaked" with the cleaner. This may cause deterioration of the rubber
compound used in the backing construction of some carpets.
NOTE: Neutral soap and water may also be used, but at the risk of color
removal.
Make certain that carpets are thoroughly dry before closing all
windows and door openings to prevent possible mildewing of the
carpet.
