The roll bar can be moved manually when
the ignition is switched on (
page 36).Raising the roll bar
Lift the switch for the retractable hard-
top.
Press and hold button2 until the roll
bar is raised.
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.
Warning!
G
If the roll bar warning light in the ta-
chometer remains lit after starting the en-
gine, there is a malfunction. In the display
you see the message
Raise the
roll-over bar
.
For safety reasons, drive only with the roll
bar upright until the malfunction is repaired.
Have your vehicle checked at an authorized
Mercedes-Benz Center.

Occupant safety
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
Warning!
G
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
passenger front airbag will not deploy only if
the 7 indicator lamp remains illuminat-
ed.
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the passenger seat until the system has
been repaired.
Warning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
passenger seat. Signals from such devices
may interfere with the BabySmart
TM system.
Such signal interference may cause the
7 indicator lamp not to come on during
self-test or be continuously lit, indicating
that the system is not functioning.
