very dark


the camera is exposed to a very bright
white light

Safe vehicle operation depends on proper
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.
i
If 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.
i
Substitute bulbs will be brought into use
when the following lamps malfunction:


Turn signal lamps


Brake lamps


Parking lamps


Tail lamps
Read and observe the messages in the multi-
function display (
