Notes:
For safety reasons, the hardtop can only be unlocked
while the vehicle is standing still, and within
10 seconds after turning the key to steering lock
position 2 or beyond.
If the indicator lamp in the soft top switch blinks while
activating the switch, the battery voltage may be
insufficient - start engine to charge battery before
shutting engine off and attempting to unlock the roof
again.
If the indicator lamp continues to blink, remove the
hardtop (see page 137), and have the system checked at
your authorized Mercedes-Benz Center as soon as
possible.
Warning!
The raising or lowering procedure of the soft top is
not completed if the indicator lamp in the soft top
switch:
• does not go out (with key in steering lock
position 2),
• blinks when starting to drive and an alarm
sounds.
When safe to do so, immediately stop the vehicle
and lock the soft top:
• Turn key in steering lock to position 2,
• Slide soft/hardtop switch forward.
Do not drive the car with the hardtop not locked, as
that could cause personal injury to you or your
passenger, or personal injury or property damage
to others.
