Notes:
When in operation, the seat heater consumes a large
amount of electrical power. It is not advisable to use the
seat heater longer than necessary.
The seat heaters may automatically switch off if too
many power consumers are switched on at the same
time, or if the battery charge is low. When this occurs,
the indicator lamp in the switch will blink (both
indicator lamps blink during rapid seat heating mode).
The seat heaters will switch on again automatically as
soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to
you, the seat heaters can be switched off.Seat belts and integrated restraint system
Your vehicle is equipped with seat belts for all seats,
emergency tensioning devices for the front seat belts,
dual front airbags, door mounted side impact airbags
and knee bolsters for driver and front passenger. Their
protective functions are designed to complement one
another.

The service indicator disappears automatically after
30 seconds or if button J on the instrument cluster is
pressed.
Calling up service indicator manually:
Turn the electronic key in steering lock to position 1
or 2.
Call up the trip odometer and main odometer, by
pressing button è or ÿ on the multifunction
steering wheel until the display appears. See page 88.
Press button j or k until the FSS indicator
appears.
Pressing the è or ÿ button displays the next or
previous system.
Important!
The FSS indicator does not include an engine oil level
indicator. See page 108 for engine oil level indicator.Notes:
When disconnecting vehicle battery for one or more
days at a time, such days will not be counted. Any such
days not counted by the FSS can be added by your
Mercedes-Benz Center.
The interval between services is determined by the type
of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
with short distance driving in which the engine does not
reach operating normal temperature, reduce the interval
between services.

is clear.
The defroster is automatically turned off after a
maximum of 12 minutes of operation.
If several power consumers are turned on
simultaneously, or the battery is only partially charged,

Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
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
switch again. The soft top should now be operational
again.
If the indicator lamp continues to blink, raise the soft
top manually, see page 288. 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.

Te l e A i d (optional for Canada)
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 the system is not
activated the indicator lamp in the SOS button stays on
after turning electronic key in starter switch to
position 2 and the message “TELE AID – NOT
ACTIVATED” will be shown in the multifunction display
for approx. 10 seconds.
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).
(Te l ematic 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 operational providing that the
vehicle’s battery is charged, properly connected, not
damaged and cellular and GPS coverage is available.The speaker volume of a Tele Aid call can be adjusted
when using the volume control on the multifunction
steering wheel, for raising press buttonæ and for
lowering press buttonç.
To activate, press the SOS button, the Roadside
Assistance button• or the Information button¡,
depending on the type of response required.
Shortly after the completion of your Acquaintance Call,
you will receive a user ID and password via first call
mail. By visiting www.mbusa.com and selecting “Tele
Aid” (USA only), you will have access to account
information, remote door unlock, profile and more.
Important!
Tele Aid utilizes the cellular network for
communication and the GPS (Global Positioning
System) satellites for vehicle location. If either of these
signals are unavailable, the Tele Aid system may not
function and if this occurs, assistance must be
summoned by other means.
