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.
