tive or inaccurately, or may not display ob-
stacles at all. The rear view camera does not
relieve you of the responsibility to be cau-
tious, take care and pay careful attention.
The rear view camera may not show objects
which are:

very close to the rear bumper

ing your vehicle in an area where it is
very dark

the camera is exposed to a very bright
white light

the immediate surroundings are illumi-

there is a sudden change in tempera-
ture, e.g. if you drive into a heated ga-
rage from the cold (lens condensation)

In this case, have the position and set-
ting of the camera checked by a quali-
fied specialist workshop.

exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Light Truck Center for
headlamp adjustment.iIf the headlamps or front fog lamps are
fogged up on the inside as a result of high humid-
ity, driving the vehicle a distance with the lights
on should clear up the fogging.iSubstitute bulbs will be brought into use
when the following lamps malfunction:

Turn signal lamps
