48 Safety and SecurityOccupant safetyFurthermore, the occupant weight may ap-
pear to increase or decrease due to the fol-
lowing: objects hanging on the seat,
lodged underneath the seat, stuffed be-
tween the seat and middle console or the
seat and door, other passengers pushing
on the seat or objects applying pressure to
the back of the seat.
Both driver and the front passenger should
always use the 59indicator
lamp as an indication of whether or not the
front passenger is properly positioned.i
If your seat, including your trim cover and
cushion needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Warning!
G
If the 59indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
59indicator lamp goes out, or
check whether objects are caught under or
around the seat.
More information about air bag display mes-
sages (
page 649).
In the event of a collision, the air bag control
unit will not allow front passenger front air
bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 59indicator
lamp will illuminate when the engine is start-
ed and remain illuminated, indicating that
the front passenger front air bag is deacti-
vated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
59indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 59indicator lamp will illu-
minate for approximately 6 seconds when
the engine is started and then, depending on

er with respect to the operation of certain
systems and do not replace the owner’s
and/or driver’s responsibility to maintain
the vehicle’s operating safety by having all
required maintenance and safety checks
performed on the vehicle and by bringing
the vehicle to an authorized Mercedes-Benz
Center to address the malfunction and
warning messages (

Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.


The engine electronics may not be op-
erating properly.


Unburned gasoline may have entered
the catalytic converter and damaged it.

Have the problem repaired by an au-
thorized Mercedes-Benz Center as
soon as possible.
!
Shift the automatic transmission to park
positionP or reverse gearR only when the vehi-
cle is stopped in order to avoid damaging the
transmission.
!
Do not run cold engine at high engine
speeds. Running a cold engine at high engine
speeds may shorten the service life of the en-
gine. This is not covered by the Mercedes-Benz
Limited Warranty.
S63AMG and S65AMG only:
At engine temperatures below 68°F (20° C), the
maximum speed is restricted in order to protect
the engine. Avoid driving the vehicle at full speed
while the engine is cold in order to prevent pre-
mature engine wear as well as diminished com-
fort.
!
Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear which is not covered by the
Mercedes-Benz Limited Warranty.
i
To signal minor directional changes such as
changing lanes, press combination switch only
to point of resistance and release. The corre-
sponding turn signals will flash three times.

544 Controls in detailUseful featuresEmergency calls
An emergency call is initiated
automatically following an accident in
which the emergency tensioning devices
(ETDs) or air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. For instructions on initiating an
emergency call manually (
page 545).
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message:

function display


“Emergency Call Activated” appears in
the COMAND display
and the audio system is muted. When the
connection is established, the message:


“Call Connected” appears in the multi-
function display

All information relevant to the emergency,
such as the location of the vehicle (deter-
mined by the GPS satellite location sys-
tem), vehicle model, identification number
and color are generated.
A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to deter-
mine more precisely the nature of the acci-
dent provided they can speak to an
occupant of the vehicle.The Tele Aid system is available if


it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection,
and cellular air time


the relevant monitoring service and
GPS coverage are available and pass
the information on to the Response
Center


there is sufficient voltage in the vehicle
batteries
i
During the emergency call message “Emer-
gency Call Activated” is displayed, operation
from COMAND is not possible. The automatic cli-
mate control can be still adjusted using the
switches on the climate control panel.
i
If no vehicle occupant responds, an ambu-
lance will be sent to the vehicle immediately.
i
Location of the vehicle on a map is only pos-
sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.Warning!
G
If the indicator lamp in the SOS button is
flashing continuously and there was no
voice connection to the Response Center
established, then the Tele Aid system could
not initiate an emergency call (e.g. the rele-
vant mobile phone network is not available).

571 Operation
At the gas station

Take off the fuel filler cap and set it in
the direction of arrow 2 and place it
into holder 3 located on the inside of
the fuel filler flap.
To prevent fuel vapors from escaping
into open air, fully insert filler nozzle
unit.

Only fill your tank until the filler nozzle
unit cuts out – do not top off or over-
fill.

Replace the fuel cap by turning it clock-
wise until it audibly engages.

Close the fuel filler flap.
You should hear the latch close shut.Warning!
G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas
discharge. This could cause the gas to spray
back out when removing the fuel pump noz-
zle, which could cause personal injury.i
Make sure to close the fuel filler flap before
locking your vehicle as the flap locking pin pre-
vents closing after you have locked the vehicle.
