206 Controls in detailDriving systems
Driving systemsThe driving system of your vehicle is
described on the following pages:
Cruise control, with which the vehicle
can maintain a preset speed
For information on the BAS, ABS and ESP
driving systems, see “Driving safety sys-
tems” (
page 72).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set or resume
cruise control at any speed over 20 mph
(30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 20).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must remain at all
times responsible for the vehicle speed and
for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

iDepressing the accelerator pedal does
not deactivate cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.
iVehicles with automatic transmission:
When you use the cruise control lever
to decelerate, the transmission will
automatically downshift if the engine’s
braking power does not brake the
vehicle sufficiently.
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed could cause an accident and/or seri-
ous injury to you and others.

Useful features
Upgrade signals
The Tele Aid system processes calls using
the following priority:
Automatic emergency – First priority
Manual emergency – Second priority
Roadside assistance – Third priority
Information – Fourth priority
Should a higher priority call be initiated
while you are connected, an upgrade
(alternating) tone will be heard, and the
appropriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to
retransmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retrans-
mission is completed. Once a call is
concluded, a beep will be heard and the
respective indicator lamp will stop flash-
ing. The COMAND* system operation will
resume.
!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 Customer Assistance
at 1-800-FOR-MERCedes
(1-800-367-6372) in the USA or
Customer Service at 1-800-387-0100
in Canada.iThe indicator lamp in the respective
button flashes until the call is con-
cluded. Calls can only be terminated by
a Response Center or Customer Assis-
tance Center representative except
Roadside Assistance and Information
calls, which can also be terminated by
pressing buttonì on the multifunc-
tion steering wheel.
iWhen a Tele Aid call has been initiated,
the audio system or the COMAND* sys-
tem audio 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. Dis-
connect the coiled cord and place the
call. The COMAND* navigation system
(if engaged) will continue to run. The
display in the instrument cluster is
available for use, and spoken com-
mands 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.
265 Operation
Maintenance
Maintenance
We strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Center, in accordance with
the Service Booklet at the times called for
by the FSS (Flexible Service System).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times/mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
FSS will notify you when your next service
is due.
Approximately one month before your next
service is due, one of the following
messages will appear in the multifunction
display while you are driving or when you
switch on the ignition (example service A):SERVICE A IN XX DAYS
SERVICE A IN XX MILES (KM)
SERVICE A DUE NOW!
The type of service due is indicated in the
multifunction display:
9Minor service (A)
´Major service (B)
Clearing the service indicator
The service indicator is automatically
cleared
after ten seconds when you switch on
the ignition or when reaching the
service threshold while driving
after 30 seconds, once the suggested
service term has passed
You can also clear it yourself.
Press the reset button on the
instrument cluster (
page 22).
Service term exceeded
If you have exceeded the suggested
service term, you will see the following
message in the multifunction display:SERVICE A EXCEEDED BY XX DAYS
SERVICE A EXCEEDED BY XX MI (KM)An acoustic signal will also sound.
iThe interval between services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.

display.
Resetting the service indicator
In the event that the service on your
vehicle is not carried out by an authorized
Mercedes-Benz Center, you can reset the
service indicator yourself.

iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the service indica-
tor. To arrive at the true service
deadline, you will need to subtract
these days from the days shown in the
service indicator.
Do not confuse the service indicator
with the engine oil level indicator:.
iIf the service indicator was
inadvertently reset, have a
Mercedes-Benz Center correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next
service interval which will result in
engine damage not covered by the
Mercedes-Benz Limited Warranty.
280 Practical hintsWhat to do if …Messages in the display
The control system shows warning and
malfunction messages in the multifunction
display.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the malfunction memory menu in
the control system (
page 122) displays
both cleared and uncleared messages.
High-priority messages appear in the
multifunction display in red color.
Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (page 22) and are
then stored in the malfunction message
memory (
page 122).On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may
appear in the display. High priority
messages appear on a red background.
