Power top
Power top
Automatic power top
General information
The soph isticated des ign of the fab ric power top allows you to
operate it eas ily and quickly. You can open and close the power top
w hile dr iv ing as long as the vehicle is t raveling below 30 mph. When
open, the power top is stored in a specia l compartment which is
equipped wi th a cover.
Under normal cond it io ns, t he power top is wi nd- and waterproof. In
ra re cases, small droplets o f water may form under extreme weather
condi tions such as tor rential o r prolonged ra in. That is norma l and no
cause for concern.
Follow t he main tenance ins truct ions to main tain t he attra ctive
appea rance of the convert ib le and to ensu re t hat it does not leak
~ page 2 63, "P ower top care". A lso obse rve the follow ing :
• Only o pen and close t he power top when it is clea n. Shar p-edged
part icles of d irt ca n scratch the rear window when the power top is
folde d and can c ause abras ion th at resul t in damage to the p ower top
over time . You should a lso remove ice and snow before opening the
powe r top.
• Never remove snow and ice w ith sharp-edged ob jects. Yo u can
remove ice fr om the re ar w indow with a st and ard i ce s crap er.
• You shou ld only open the powe r top when it is comp lete ly dry.
Ope ning the power top and stow ing i t in the compartmen t when it is
wet can cause marks on the top that detract from its appearance.
Mi ldew can als o fo rm if the power top is s towed for an exte nded
period of time when it is wet.
• Do not leave the powe r top open fo r seve ral weeks at a t ime .
Always close it between uses to prevent disco loration and creases
fr om f orming. Thi s is especi ally impo rtan t if it was not comple tely dry
w hen stowed. •
Ope ning or clos ing the power top in temperatures be low 32 °F
(0 °C) is not recommended because the flexib ility of the fabr ic
decreases is sub- zero tempe ratu res.
& WARNING
• When operating the power top, make sure the function is not
affe cted by wind or other factors and that it does not interfere
with other drivers .
• Never drive when the power top is not lo cked correctly . The
wind from driving could cause the power top to open . This can
result in injuries and damage to the vehicle.
• When opening and closing the power top, make sure no one
will be injured by the supports and other moving part s.
• Ope rating the power top reduces the headroom in the rear of
the vehicle. Make sure there is enough clearance between the rear
passenger and the power top when opening and closing it.
• When operating the power top, visibility to the rear is limited.
Avo id operating the top while driving in reverse.
0 Note
• Always make sure there is enough clearance above the vehicle so
t he power top is not dam age d when opening a nd clos ing it .
• Do not store any objects in the power top compartment to avoid
damage whe n open ing the to p.
[ i ] Tips
• T o prevent the batte ry from d ischarging, do not o pe n or close the
power top repeatedly when the engine is sw itched off . .,
