General information
A pp lies to: ve hicles w ith power top
The power top opens and closes automatically .
When open, the power top is stored completely in the power top compartment. The power top
can be opened or closed at speeds up to 30 mph
(SO km/h).
Under normal conditions, the power top is wind­
and waterproof. In rare cases, small droplets of
water may form under extreme weather condi­
tions such as torrential or prolonged rain. That is
normal and no cause for concern.
Follow the care instructions to keep the power
top free of leaks and to maintain its appearance
c:::> page 354, Care and cleaning. Also observe the
following:
- Open and stow the power top only when it is
clean and dry. Stowing the power top when it is
damp can create imprints in it, and if it is left
that way for long periods of time, mildew and
other damage can form. To prevent scratching
or damaging the power top, do not use any
sharp-edged objects to remove ice and snow.
The rear window may be cleared with a stand ­
ard ice scraper .
- Do not leave the power top open for several
weeks or the creases in it may become discol­
ored .
- Do not open the power top when the tempera ­
ture is be low 32 °F
