62 Safety and SecurityOccupant safetySafety guidelines for the seat belt,
emergency tensioning device and
airbagWarning
G
Damaged seat belts or belts that were
highly stressed in an accident must be
replaced and their anchoring points
must also be checked. Use only belts in-
stalled or supplied by an authorized
Mercedes-Benz Light Truck Center.
No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, passenger front airbag cov-
er, or door trim panels, and installation
of additional electrical / electronic
equipment on or near SRS components
and wiring. Keep area between airbags
and occupants free from objects (e.g.
packages, purses, umbrellas, etc.).
Airbags and emergency tensioning de-
vices (ETDs) are designed to function on
a one-time only basis. An airbag or ETD
that was activated must be replaced.
Do not pass belts over sharp edges.
They could tear.
Do not make any modification that could
change the effectiveness of the belts.
Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.
Do n o t h a ng i te ms su ch as c o at ha n ger s
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when curtain airbag is deployed.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
Airbag system components will be hot
after an airbag has inflated. Do not
touch.
In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air-
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Light Truck Center.
For your protection and the protection
of others, when scrapping the airbag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Light Truck Center.
Given the considerable deployment
speed and the textile structure of the
airbags, there is the possibility of abra-
sions or other injuries resulting from air-
bag deployment.

153 Controls in detail
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.
Parktronic*, with which you can assist
your parking maneuvers.
The driving systems BAS, ABS, ESP, EBB
and 4-ETS, are described in the “Safety
and Security” section (
page 76).
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).
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.
