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.
Wa r n i n g !
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.

147 Soft top
Technical
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index For safety reasons, the soft top cannot be unlocked
while driving.
However, if the soft top is not completely locked, it can
be locked while driving by pushing the soft/hardtop
switch forward.
If the indicator lamp in the soft top switch blinks while
activating the switch,
• the battery voltage may be insufficient - start engine
and let run while activating switch,
• the system may be overloaded (for example after
lowering or raising the soft top approx.
5 consecutive times) - after approx. 2 minutes the
soft top switch may be activated again,
• and the power supply was interrupted (battery
disconnected or empty), the soft top cannot be fully
raised or lowered.
To raise the soft top, for safety reasons, first remove key
from steering lock. Lower soft top by hand into
compartment, and resynchronize the power windows.
See page 116.
To lower the soft top, first resynchronize the power
windows. See page 116.If t he indicator la mp continues to bl ink, l ock th e sof t top
manually. See page 253.
Have the system checked at your authorized Mercedes-
Benz Center as soon as possible.
Note:
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.
Permanent creases in the plastic window, caused by
storage of the soft top in the storage compartment,
cannot be avoided.
The soft top may become moldy 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.

Important!
The initial activation of the Tele Aid system may only be
performed by completing the subscriber agreement and
placing an acquaintance call using the “SOS” button.
Failure to complete either of these steps will result in a
system that is not activated.
If you have any questions regarding activation, please
call the Response Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
(Telematic Alarm Identification on Demand)
The Tele Aid system consists of three types of response;
automatic and manual emergency, roadside assistance
and information.
The Tele Aid system is always operational, providing
that the vehicle’s battery is charged and properly
connected. To activate, press the “SOS” button, the
Roadside Assistance button or the Information
button¡, depending on the type of response
required.System self-check
Initially, after turning the key in steering lock to
position 2, malfunctions are detected and indicated (the
indicator lamps in the “SOS” button, the Roadside
Assistance button and the Information
button¡ stay on longer than 5 seconds or do not
come on).
If a malfunction is indicated as outlined above, have the
system checked at the nearest Mercedes-Benz Center as
soon as possible.
Important!
Always make sure that the indicator lamp in the
“SOS” button remains illuminated for approx. 5 seconds
during the system self-check after turning key in
steering lock to position 2.
Emergency calls
An emergency call is initiated automatically following
an accident in which the Emergency Tensioning
Retractors (ETR’s) or airbags deploy. An emergency call
can also be initiated manually by opening the cover next
to the interior rear view mirror labeled “SOS”, then

Notes:
A warning sounds when the driver’s door is opened
while the 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 traffic. This precaution helps 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.Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the key from the steering
lock. Do not leave the key in steering lock position 0.

Have your vehicle winterized at your authorized
Mercedes-Benz Center before the onset of winter.
• Change the engine oil if the engine contains an oil
which is not approved for winter operation. For
viscosity (SAE/CCMC class) and filling quantity,
see page 276.
• Check engine coolant anticorrosion/antifreeze
concentration.
• Additive for the windshield washer and headlamp
cleaning system: Add MB Concentrate “S” to a
premixed windshield washer solvent/antifreeze
which is formulated for below freezing
temperatures, see page 88.
• Test battery: Battery capacity drops with decreasing
ambient temperature. A well charged battery helps
to ensure that the engine can be started, even at low
ambient temperatures.
• Tires: We recommend M+S rated radial-ply tires on
all four wheels for the winter season. Observe
permissible maximum speed for M+S rated
radial-ply tires and the legal speed limit.Note:
In winter operation, the maximum effectiveness of the
antilock brake system (ABS) or electronic stability
program (ESP) can only be achieved with M+S rated
radial-ply tires and/or snow chains recommended by
Mercedes-Benz. Snow chains maximize performance.
Block heater (for Canada only)
The engine is equipped with a block heater.
The electrical cable may be installed at your authorized
Mercedes-Benz Center.

The malfunction indicator lamp for the ESP is combined
with that of the BAS.
The yellow BAS/ESP malfunction indicator lamp in the
instrument cluster and the yellow ESP warning
lampv in the speedometer dial come on with the
key in steering lock position 2. They should go out with
the engine running.
If the BAS/ESP malfunction indicator lamp comes on
permanently with the engine running, a malfunction
has been detected in either system. Pressing the
a ccelera tor peda l will require greater e ffort. Only partia l
engine output will be available.
If the BAS malfunctions, the brake system functions in
the usual manner, but without BAS.
If the BAS/ESP malfunction indicator lamp come s on,
have the BAS or ESP checked at your authorized
Mercedes-Benz Center as soon as possible.
With the ABS malfunctioning, the ESP is also switched
off.Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lamp in speedometer
dial comes on). For this reason, all wheels, including the
spare wheel, must have the same tire outside diameter.
When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.
In winter operation, the maximum effectiveness of the
ESP is only achieved with Mercedes-Benz recommended
M+S rated radial-ply tires and/or snow chains.
Synchronizing ESP
If the power supply was interrupted (battery
disconnected or empty), the BAS/ESP malfunction
indicator lamp may be illuminated with the engine
running.
Turn steering wheel completely to the left and then to
the right. The BAS/ESP malfunction indicator lamp
should go out.
