440 Practical hintsResetting activated head restraintsIf the active head restraints have been trig-
gered in an accident, the active head re-
straints must be reset. Otherwise, the
active head restraints cannot offer any ad-
ditional protection in the event of another
rear-end collision.
You can tell that the head restraints have
been triggered when they have been
moved forward and cannot be adjusted.

Mercedes-Benz vehicle literature
pouch.

Guide reset tool into center of head re-
straint between head restraint cushion
and rear head restraint cover.

arrow.

Press reset tool downward until you
hear the head restraint release
mechanism audibly engage.

Pull out reset tool.

Firmly press head restraint cushion
backward towards the rear of the vehi-
cle until it engages.

Repeat this procedure on the active
head restraints for second head re-
straint.

Bulbs
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. Contact your au-
thorized Mercedes-Benz Center for head-
lamp 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 lamps malfunction. Read and observe mes-
sages in the multifunction display (
page 422).

Bulbs and bulb sockets can be very hot. Al-

a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas.
A bulb can explode if you:

touch or move it when hot


drop the bulb


scratch the bulb
Wear eye and hand protection.
Because of high voltage in Bi-Xenon* lamps,
it is dangerous to replace the bulb or repair
the lamp and its components. We recom-
mend that you have such work done by a
qualified technician.
