344 OperationVehicle care
Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a damp cloth.Headlamps, tail lamps, side markers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water.
iAfter running the vehicle through an au-
tomatic car wash, wipe any wax off of
the windshield (
page 345). This will
prevent smears and reduce wiping
noise which can be caused by residual
wax on the windshield.
When leaving the car wash, make sure
that the mirrors are folded out. Other-
wise they may vibrate.
!Do not use chrome cleaner on orna-
mental moldings. Although ornamental
moldings may have chrome appear-
ance, they could be made of anodized
aluminum that will be damaged when
cleaned with chrome cleaner. Instead,
use a damp cloth to clean those orna-
mental moldings.
For very dirty ornamental moldings of
which you are sure are chrome-plated,
use a chrome cleaner. If in doubt
whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Center.
!Only use window cleaning solutions
that are suitable for plastic lamp lens-
es. Window cleaning solutions which
are not suitable may damage the plas-
tic lamp lenses of the headlamps.
Therefore, do not use abrasives, sol-
vents or cleaners that contain solvents.
Never apply strong force and only use a
soft, non-scratching cloth when clean-
ing the lenses. Do not attempt to wipe
dirty lenses with a dry cloth or sponge.
Otherwise you may scratch or damage
the lens surface.

Replacing bulbs
Replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp
assemblies 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 Center for headlamp
adjustment.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of
high humidity, driving the vehicle a
distance with the lights on should clear
up the fogging.
iSubstitute bulbs will be brought into
use when lamps malfunction. Observe
the messages in the multifunction
display (
