6. Turn locking handle 90° clockwise and pull soft top
frame carefully down until it meets the windshield
header attachment points.
Turn locking handle counterclockwise to the stop to
lock the soft top.
Fold locking handle up until it locks in place.
The indicator lamp in the soft top switch goes out –
the lowering procedure is completed. If the soft top switch is held or is released and pressed
again within approximately 2 seconds, the side
windows will close. If the roll bar was previously in the
upright position, it will return to that position.
The side windows can also be closed/opened later on.
Press/lift soft top switch twice and hold, see page 148.
However, the side windows and the roll bar can also be
activated using their respective switches, see page 146

cluster displayPractical hints Car care Index If the indicator lamp in the soft top switch blinks slowly
while activating the switch,
•the battery voltage may be insufficient – start
engine and let it run while activating switch,
•the system may be overheated (for example after
lowering or raising the soft top approx. 5
consecutive times) – after approx. 10 minutes the
soft top switch may be activated again.
If indicator lamp in the soft top switch blinks rapidly
while activating the switch,
•the trunk lid and/or the luggage cover may be open,
and need to be closed,
•the soft top is still locked during the opening
procedure and needs to be unlocked,
•the opening/closing procedure is interrupted.
In this case the soft top needs to be synchronized.
Turn electronic key in steering lock back to
position 0, and then to position 2. Activate soft top
sw itch again. Th e sof t top should now be opera tiona l
again.
If the indicator lamp continues to blink, raise the soft
top manually, see page 291. Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
Notes:
If the roll bar was raised automatically, the process of
raising or lowering the soft top will take somewhat
longer, as the roll bar must first be lowered.
Whenever possible, park vehicle in the shade as
continuous exposure to sun rays can prematurely
deteriorate the soft top material.
The soft top may become moldy and receive permanent
creases if it is kept in the storage compartment for an
extended period.
Therefore, we recommend raising and airing it
thoroughly with the side windows open (do not expose
it to the sun) at regular intervals during the wet and
cold seasons.
To prevent damage, the soft top must be dry and clean
before lowering it into the storage compartment. There
is the possibility of sharp-edged dirt particles damaging
the soft top or scratching the rear window.

cluster displayPractical hints Car care Index Emission control
Certain systems of the engine serve to keep the toxic
components of the exhaust gases within permissible
limits required by law.
These systems, of course, will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the engine should,
therefore, be carried out only by qualified Mercedes-
Benz authorized center technicians. Engine adjustments
should not be altered in any way. Moreover, the
specified service jobs must be carried out regularly
according to Mercedes-Benz servicing requirements.
For details refer to the Service Booklet.
Wa r n i n g !
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon monoxide,
and inhaling it can cause unconsciousness and
lead to death.Do not run the engine in confined areas (such as a
garage) which are not properly ventilated. If you
think that exhaust gas fumes are entering the
vehicle while driving, have the cause determined
and c orrec ted imm ediately. If you m ust dri ve under
these conditions, drive only with at least one
window fully open.

If the indicator lamp continues to flash or the system
does not reset, contact the Response Center at
1-800-756-9018 (in the USA) or 1-888-923-8367 (in
Canada), or Mercedes-Benz Client Assistance at
1-800-FOR-MERCedes (1-800-367-6372) in the USA or
Customer Service at 1-800-387-0100 in Canada.
Notes:
The indicator lamp in the respective button f lashes until
the call is concluded. Calls can only be terminated by a
Response Center or Client Assistance Center
representative except Roadside Assistance and
Information calls, which can also be terminated by
pressing ìbutton on the multifunction steering
wheel.When a Tele Aid call has been initiated, the audio
system or the COMAND system audio (only vehicles
with COMAND) is muted and the selected mode (radio,
tape or CD) pauses. The optional cellular phone (if
installed) switches off. If you must use this phone, the
vehicle must be parked. Disconnect the coiled cord and
place the call. The navigation system (if engaged) will
continue to run. The display in the instrument cluster is
available for use and spoken commands are only
available by pressing the RPT button on the COMAND
unit. A pop-up window will appear in the COMAND
display to indicate that a Tele Aid call is in progress.

If the el ectronic key is lef t in th e steering lock position 0
for an extended period of time, it can no longer be
turned in the lock. In this case, remove electronic key
from steering lock and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
steering lock. Do not leave th e ele ctronic key in steering
lock position 0.Notes:
A warning sounds when the driver’s door is opened
while the electronic key is in steering lock position 1
or 0.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go tra f f ic. Th is pre cau tion h elps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example: Heated seats, rear window
defroster. In addition, the automatic climate air volume
control should be set to the lowest position.
The steering lock can only be unlocked with the vehicle
battery properly charged and connected.

Te ch n ica l

cluster displayPractical hints Car care Index Winter driving instructions
The most important rule for slippery or icy roads is to
drive sensibly and to avoid abrupt acceleration, braking
and steering maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding, move
selector lever to position “N”. Try to keep the vehicle
under control by corrective steering action.
Road salts and chemicals can adversely affect braking
efficiency. Increased pedal force may become necessary
to produce the normal brake effect. We therefore
recommend depressing the brake pedal periodically
when traveling at length on salt-strewn roads. This can
bring road salt impaired braking efficiency back to
normal. A prerequisite is, however, that this be done
without endangering other drivers on the road.If t he veh icle is pa rked af te r b eing driven on sal t trea ted
road s, th e braking ef f ic iency should be tested as soon a s
possible after driving is resumed while observing the
safety rules in the previous paragraph.
Wa r n i n g !
If the vehicle becomes stuck in snow, make sure
that snow is kept clear of the exhaust pipe and
from around the vehicle with engine running.
Otherwise, deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in unconsciousness
and death.To assure sufficient fresh air ventilation, open a
window slightly on the side of the vehicle not
facing the wind.
