leather gets wet, dry with a soft clean
cloth. Allow the leather to dry in a venti-
lated shaded area.

with a neutral detergent, apply a
cleaner that does not contain an
organic solvent.

ing the leather as these could
cause discoloring.

er upholstery. Be especially careful
to avoid oil spots. Try to keep your

may cause the leather surface to
harden and shrink. Keep your ve-
hicle in a shaded area, especially in
the summer.
