Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When scrapping the emergency tensioning
device, our safety instructions must be fol-
lowed. These are available at your autho-
rized Mercedes-Benz Center.!Do not place objects heavier than 20
lbs (9 kg) on the front passenger seat.
This could cause the front or side im-
pact airbag on the front passenger side
to deploy in a crash which exceeds the
system's deployment threshold.
Warning!
G
This vehicle is a two occupant vehicle. The
rear storage area is not intended for use by
occupants and is not equipped for properly
seating or restraining occupants. Thus this
area should never be used by any persons.
Before operating the roll bar switch make
sure that the roll bar’s path is clear and no
persons are injured by the moving roll bar
due to inattention. Raising or lowering of the
roll bar could injure someone inadvertently
occupying the rear storage area.
For your own safety we recommend to drive
with the roll bar raised if the outside temper-
ature is below +5°F (-15°C).!If the outside temperature falls below
+5°F (-15°C), the roll bar must be
raised manually using the buttons pro-
vided to avoid damaging the hydraulics.
iWhen the roll bar is raised automatical-
ly, you will hear a ratcheting sound.

trunk.
The trunk lid is open.
Close the trunk lid.
The battery voltage is too low.
Start engine and let run while acti-

self down. For safety reasons, no more
than five consecutive attempts may be
made to raise or lower the hardtop.
After about ten minutes you may
again attempt to open or close the
retractable hardtop again.
If the indicator lamp in the retractable
hardtop switch blinks when starting off or
while driving and you hear a warning sound
for a maximum of 10 seconds, the retract-
able hardtop is not locked.
Properly lock the retractable hardtop
(page 162) before continuing to

ter you have carried out the above actions,
there is a malfunction.

luggage cover is closed and the trunk lid is
completely opened.
Close the luggage cover.
Press button3.
The hardtop lowers. Button3 is dimly
lit.
Electrical outlet

(cigar lighter type).
Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Center for informa-
tion on the installation of an approved
external antenna. Refer to the radio trans-
mitter operation instructions regarding use
of an external antenna.
!Only close the trunk if the roof is com-
pletely lowered. Otherwise you could
damage the hardtop.
If you begin to close the trunk lid before
the hardtop is completely lowered, the
button3 will blink and a warning will

iThe electrical outlet can be used to ac-
commodate electrical consumers (e.g.
air pump, auxiliary lamps) up to a max-
imum of 180 W.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or serious
personal injury.
