The service indicator disappears automatically after
30 seconds or if button Jon the instrument cluster is
pressed.
Calling up service indicator manually:
Turn the electronic key in starter switch to position 1.
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 124.
Press button j or k until the FSS indicator
appears.
The next or previous system is displayed by pressing
button è or ÿ.
Important!
The FSS indicator is not an engine oil level indicator.
See page 154 for engine oil level indicator.Note:
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.

Residual engine heat utilization
With the engine switched off, it is possible to continue
to heat or ventilate the interior for a short while. Air
volume and distribution are controlled automatically.
To s elec t:
Turn the electronic key in starter switch to position 1
or 0 or remove it altogether.
Press button T. The display shows “REST”.
This function selection will not activate if the battery
level is insufficient. The function switches off automatically:
•if the electronic key in starter switch is turned to
position 2,
•after approximately 30 minutes (if residual engine
heat utilization is selected on the optional rear air
conditioner: after approximately 15 minutes),
•if the battery voltage drops.
Note:
The battery symbol # will appear in the automatic
climate control display some time before the residual
engine heat utilization is switched off if the battery
voltage drops.

automatic air conditioner. The indicator lamp in the
button illuminates.
To ca nc el:
Press the F button in the control panel of the
automatic air conditioner. The indicator lamp in the

Note:
Heavy accumulation of snow and ice should be removed
before activating the defroster. The rear window defroster uses a large amount of power.
To keep the battery drain to a minimum, turn off the
defroster as soon as the rear window is clear.
The defroster is automatically turned off after
approximately 6–23 minutes of operation depending on
the outside temperature and vehicle speed.
If several power consumers are turned on
simultaneously, or the battery is only partially charged,
it is possible that the defroster will automatically turn
itself off. When this happens, the indicator lamp inside
the switch starts blinking.
As soon as the battery has sufficient voltage, the
defroster automatically turns itself back on.

To avoid damaging the seals, do not transport any
objects with sharp edges which can stick out of the
sliding / pop-up roof.
The sliding/pop-up roof can be opened or closed
manually should an electrical malfunction occur, see
page 369.
Synchronizing the sliding / pop-up roof

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 (vehicles with KEYLESS-GO:
operating position, see page 228) 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 buttonæand 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, Info Services
* profile
and more.
* Optional System self-check
Initially, after turning the electronic key in starter
switch 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 10 seconds or do not
come on). The message “TELE AID – VISIT
WORKSHOP” appears for approx. 10 seconds in the

cluster displayPractical hints Car care Index Important!
If the electronic key is left in the starter switch
position 0 for an extended period of time, it can no
longer be turned in the lock. In this case, remove
electronic key from starter switch and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
starter switch. Do not leave the electronic key in starter
switch position 0.Notes:
A warning sounds when the driver’s door is opened
with the electronic key in starter switch 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. In addition, the
automatic climate air volume control should be set to
the lowest position.

see page 226).
All electrical consumers can be operated. Gear selector
is unlocked.
“Off” position (electronic key removable from starter
switch).
Most electrical consumers cannot be operated.
The selector lever is locked in position “P”.
Notes:
For improved recognition of the KEYLESS-GO-card the
doors should be closed when pressing the start- / stop
button.
The gear selector lever can only be moved with the
vehicle battery charged and connected, and the starter
switch in the Operation position. With the gear selector
lever in position “P”, the brake pedal must also be
depressed.Important!
For the KEYLESS-GO-system to function properly, the
operator should observe the following:
•If the KEYLESS-GO-card is positioned farther away
from the vehicle (e.g. inside clothing or briefcase),
the vehicle cannot be locked (see page 40) or started
with the start-/stop button (see page 231).
•If the KEYLESS-GO-card is removed from the vehicle
while the engine is running, or by placing the card
in front of the center armrest (see page 195), the
message “CHIP-CARD – NOT RECOGNIZED!” will
appear repeatedly while driving in the
multifunction display, see page 322.

•Do not forget, the engine can be started by anyone if
a KEYLESS-GO-card is left inside the vehicle.
•To be able to operate the vehicle in the case of a
malfunction in the KEYLESS-GO-system (e.g. strong
radio frequency disturbance), we recommend that
you carry the electronic key plus mechanical key
with you and keep them in a safe place so that they
are always handy. Never leave the electronic key in
the vehicle.
•To avoid radio transmission interference, never store
the KEYLESS-GO-card together with other electronic
items (e.g. cellular telephones, other KEYLESS-GO-
cards) or metallic objects (e.g. coins, metal foil).Notes:
