58 Safety and SecurityOccupant safetySafety guidelines for the seat belt, 
emergency tensioning device and 
airbag
When you sell your vehicle we strongly 
urge you to give notice to the subsequent 
owner that it is equipped with an SRS by 
alerting them to the applicable section in 
the Operator’s Manual.Warning!
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 ETDs are designed to func-
tion on a one-time-only basis. An airbag 
or emergency tensioning device (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.
An airbag system component within the 
steering wheel gets hot after the airbag 
has inflated. Do not touch.
Improper work on the system, including 
incorrect installation and removal, can 
lead to possible injury through an unin-
tended activation of the SRS.
In addition, through improper work 
there is a risk of rendering the SRS inop-
erative or causing unintended airbag de-
ployment. Work on the SRS must 
therefore only be performed by an au-
thorized 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.

162 Controls in detailDriving systems
Driving systemsThe driving systems of your vehicle are de-
scribed on the following pages:
Cruise control, with which the vehicle 
can maintain a preset speed.
Rear Park 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 71).
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 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 22).
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.
