Retractable hardtop
Important!
A minimum clearance height of 5
1/2 ft. (1.65 m) and an
additional 10 in (25 cm) length behind the vehicle is
required to lower or raise the hardtop.
The additional space is required since the roof moves up
and the trunk lid back during raising and lowering
operations.
The raising or lowering operations can only be started
with the luggage cover and trunk lid closed.
The raising or lowering procedure is immediately
interrupted by releasing the hardtop switch.
Do not operate the roof while a roof luggage carrier is
installed.To prevent damage to hardtop or luggage / cargo when
lowering the roof:
•load trunk only to the height of the luggage cover,
•do not permit luggage / cargo to raise the closed
luggage cover,
•do not load anything on top of the luggage cover,
•do not place anything on shelf behind roll bars.
Note:
To prevent the hardtop from being lowered
unintentionally while a roof luggage carrier is installed,
keep luggage cover in trunk in the open position.
Wa r n i n g !
Before operating the switch for the retractable
hardtop make sure that no persons due to
inattention are injured by the moving parts
(retractable roof, roof frame, and trunk lid).Hands must never be placed near the roof frame,
upper windshield area, hardtop, shelf behind roll
bars, or trunk lid while the retractable hardtop is
being raised or lowered. Serious personal injury
may occur.
