Soft top car e
Particular care should be take n when
washing the fabric soft top. C arefully
vacuum the soft top before washing, to
rem ov e e xce ss dus t and dirt p artic le s .
W ash in s hade with a s ponge (a chamois
lea the r will lea ve lint, while a brus h may
abrade the thre ads ) and use an O pel Car
Shamp oo and lukewa rm wate r solution.
W ash the entire top uniformly to avoid
rings or spots. Rinse with plenty of clean
wate r.
Re move surface water with a s ponge and
allow to air dry . Be sure to allow the soft top
to dry complete ly be fore stowing , as
prolong ed stowage of a wet or dam p soft
top will ca use rotting of the fabric.zRe move bird droppings from the soft top
imme diate ly.
zDo not use agg ressive cleaning agents
or stain remove rs.
zDo not direc t water je ts on to the e dges
of the soft top.
zDo not use s harp-edge d obje cts to
rem ove snow and ic e from the soft top.
Whils t the s oft top is weathe rp roof, it
cannot b e guarante ed to b e fully
waterproof if the v ehicle is w ashe d in an
autom atic car wash. It is the refore
recommended tha t the vehicle is hand-
washe d and that automatic c ar was hes are
avoided .E xte rior st or age
Due to the soft top design be ing
we atherproof and not wate r tight in all
conditions , exte nded periods of rainfa ll
ma y res ult in s om e w ater colle ction in the
p a s s en g e r co m p a r t m e nt . T h er ef o r e, i t i s
recommended that the vehicle is not stored
outside without a s uitab le prote ctive
cove ring s uch as a s howe r cover (availab le
from y our Opel Serv ice Partner).
Waxing
W ax yo u r veh icle regu larly, in particu lar
afte r it has bee n was he d us ing shamp oo
and a t the late st w he n wate r no longe r
forms bea ds on the paintwork, otherwise
the paintwork will dry out.
N eve r let things de te riora te this far.
Waxing p revents harmful chem ical action.
Also wax edges and folds on opened doors
and flaps as we ll as the a reas they cover.
Polishing
Polishing is nece ss ary only if the pa int
has be come dull or if solid de pos its have
be come attached to it.
Paintwork polis h with silicone forms a
protec tiv e film, making w axing
unnecessary.
Plastic body p arts must not be tre ated with
pre se rvation and polis hing a gents.
Use Metallic Paintwork W ax on vehicle s
with a metallic-e ffe ct paint finish.
