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

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

Use Metallic Paintwork W ax on vehicle s

the lock s re -grease d by a workshop.
E ng ine compar tme nt
Areas of the engine compartme nt that are
painted in the same colour as the vehicle
must be looked after lik e any other p ainted
surface.
It is adv isable to was h th e e n gin e

pre se rve it with wax. Cove r alternator and
brake /clutch fluid res e rv oir with plastic
sheets before washing the engine.
W hen was hing the e ngine with a s te am-je t
cle ane r, do not d ire ct the ste am-jet a t
components of the Anti-lock Brake System
(ABS), a ir conditioning syste m, climate
control sy ste m or the b elt drive and its
components . Prote ctive wax that has be en ap plied is
also re move d during the e ngine wash. F or
this reas on, have the e ngine, brak e s ys te m
components in the engine compartment,
axle com pone nts with ste ering, body parts

work shop using protective wax .
An engine w ash ca n be p erformed in the

D o no t u s e hi g h - p r e ss u r e j e t cl ea ne r s.Underbod y
Your v ehicle ha s a durable protective
coating in the whee l arches (includ ing the
longitudinal mem bers ), which provide s
pe rmanent prote ction a nd need s no

Be fore the sta rt of the cold we ather se ason,
che ck the c oa ting and, if ne ces s ary, have it
re stored to perfe ct condition.
C aution – com mercially available bitumen/
rubbe r m aterials can damage the coating .
We recommend that you have underbody
work carrie d out by a workshop, who
knows the p rescrib ed materials and has
experience in the use thereof.
The underbody should be washed
following the e nd of the cold weathe r
s eas on to remov e any dirt adhering to the
underbody since this may also contain salt.
Check p rotective wax coa ting and, if
