If you plan to operate your vehicle in for-
eign countries, please be aware that:

Service facilities or replacement parts
may not be readily available,

er octane rating, and improper fuel can
cause engine damage.

17 Introduction
Operating safety
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 modification made may
produce an undesired effect on other sys-
tems.
Electronic system malfunctions could seri-
ously impair the operating safety of your ve-
hicle.
Ensure that any repairs or modifications to
electronic components are carried out by an
authorized Mercedes-Benz Light Truck Cen-
ter.
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.

In the case of an accident, liquid electrolyte
may escape the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or the respiratory sys-
tem. In case it does, immediately flush af-
fected area with water, and seek medical
help if necessary.
Warning!
G
Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes.!Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.

immediately. If you must drive under these
conditions, drive only with at least one win-
dow fully open.
