16 Introduction
Operating safety
Proper use of the vehicle
Proper use of the vehicle requires that you
are familiar with the following information
and rules:

the safety precautions in this manual

the “Technical data” section in this
manual

traffic rules and regulations

motor vehicle laws and safety stan-
dards
Warning!G
Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because
the vehicle’s electronic components are in-
terconnected, any modifications made may
produce an undesired effect on other sys-
tems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
See an authorized Mercedes-Benz Light
Truck Center for repairs or modifications to
electronic components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore nev-
er turn off the engine while driving.
Warning!G
Heavy blows against the vehicle underbody
or tires / wheels, for example when running
over an obstacle, road debris or a pothole,
may cause serious damage and impair the
operating safety of your vehicle. If you feel a
sudden significant vibration or ride distur-
bance, or you suspect that damage to your
vehicle has occurred, you should turn on
your hazard warning flashers, carefully slow
down, and drive with caution to an area
which is a safe distance from the road.
Inspect the vehicle underbody and
tires / wheels for possible damage. If the ve-
hicle appears unsafe, have it towed to the
nearest authorized Mercedes-Benz Light
Truck Center or other qualified maintenance
or repair facility for further inspection or re-
pairs.
Warning!G
Various warning labels are attached to your
vehicle. These warning labels are intended
to make you and others aware of various
risks. You should not remove any of these
warning labels unless explicitly instructed to
do so by information on the label itself. Re-
moval of any of these labels may cause you
and others to be unaware of certain risks
which may result in an accident and / or per-
sonal injury.

159 Controls in detail
Control system
Control system
The control system is activated as soon as
the SmartKey in the starter switch is
turned to position1 (
page 40) or as
soon as the KEYLESS-GO start/stop
button* is in position1 (
page 41). The
control system enables you to

call up information about your vehicle

change vehicle settings
For example, you can use the control
system to find out when your vehicle is
next due for maintenance service, to set
the language for messages in the instru-
ment cluster display, and much more.

iThe displays for the audio systems (radio,
CD player) will appear in English, regardless of

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,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions
permit it to be done safely.
Bear in mind that at a speed of just
30 mph (approximately 50 km/h), your
vehicle is covering a distance of
44 feet (approximately 14 m) every second.
