Vehicle care
To prevent damage to the antenna, un-
screw and remove antenna on left rear
side of vehicle before taking the vehicle
through a car wash. Note that without the
antenna on the left rear side of the vehicle
installed, the signaling range of the
SmartKey is considerably reduced. Hold
the SmartKey in close proximity towards
the antenna base when locking and un-
locking the vehicle.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the undercarriage, do not
forget to clean the inner sides of the
wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, side makers, tail lamps,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.Wiper blades
Switch on wipers and place them in a
vertical position.
For information on placing the wipers
in a vertical position, see “Replacing
wiper blades” (
page 386).
!The windshield wipers must be in a ver-
tical position before folding them away
from the windshield. They could other-
wise damage the hood.

Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
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 Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
