Warning!
G
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving. For your safety and the
safety of others, we recommend that you
pull over to a safe location and stop before
placing or taking a telephone call. If you
choose to use the telephone while driving,
please use the hands-free device and only
use the telephone when weather, road and
traffic conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of approximately
44 feet (approximately 13.5 m) every sec-
ond.

Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:
Cruise control, with which the vehicle
can maintain a preset speed.
Rear Parking Assist*, with which you
can assist your parking maneuvers.
The BAS, ABS, ESP, 4-ETS and EBB driving
systems are described in the “Safety and
Security” section (
page 74).
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 23).
iThe cruise control should not be acti-
vated during-off road driving.
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must always
remain 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.

(“Resume” function)
Briefly push the cruise control lever to

iDepressing the accelerator pedal does
not deactivate the cruise control. After
brief acceleration (e.g. for passing), the
cruise control will resume the last
speed set.
iWhen you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the engine’s
braking power does not brake the vehi-
cle 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 endanger yourself and others.
196 Controls in detailUseful featuresUpgrade 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 (al-
ternating) tone will be heard and the ap-
propriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to re-
transmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retransmis-
sion is completed. Once a call is conclud-
ed, a beep will be heard and the
appropriate 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

tomer Service at 1-800-387-0100 in

button flashes until the call is conclud-
ed. 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 COMAND system audio is muted
and the selected mode (radio or CD)
pauses. The optional cellular phone (if
installed) switches off. If you must use
this phone, the vehicle must be parked.
Disconnect the coiled cord and place
the call. The navigation system (if en-
gaged) will continue to run. The display
in the instrument cluster is available for
use and spoken commands 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.
242 OperationMaintenance
MaintenanceWe strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Light Truck Center, in ac-
cordance with the Service Booklet at the
times called for by the FSS (Flexible Ser-
vice 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 mes-
sages will appear in the multifunction dis-
play 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
speedometer display field:
9Minor service (A)
½Major service (B)Clearing the service indicator
The service indicator is automatically
cleared
after 10 seconds when you switch on
the ignition or when reaching the ser-
vice 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 instru-
ment cluster (
page 25).
Service term exceeded
If you have exceeded the suggested ser-
vice term, you will see the following mes-
sage in the multifunction display:SERVICE A EXCEEDED BY XX DAYS
SERVICE A EXCEEDED BY XX MILES (KM)An accoustic signal will sound.
The Mercedes-Benz Light Truck Center will
reset the service indicator following a com-
pleted service.
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.

service deadline, you will need to sub-
tract 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 inadvertent-
ly reset, have a Mercedes-Benz Light
Truck 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 ser-
vice interval which will result in engine
damage not covered by the Mer-
cedes-Benz Limited Warranty.
