!To avoid damage to the seats and the seat
heating, observe the following information:
Rkeep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
Rif the seat covers are damp or wet, do not
switch on the seat heating. The seat heat-
ing should also not be used to dry the seats.
Rclean the seat covers as recommended;
see the "Interior care" section.
Rdo not transport heavy loads on the seats.
Do not place sharp objects on the seat
cushions, e.g. knives, nails or tools. The
seats should only be occupied by passen-
gers, if possible.
Rwhen the seat heating is in operation, do
not cover the seats with insulating materi-
als, e.g. blankets, coats, bags, seat covers,
child seats or booster seats.
Your seat must be adjusted in such a way that
you can wear the seat belt correctly.
Observe the following points:
RPosition the backrest in an almost vertical
position so that you are sitting virtually
upright. Do not drive with the backrest
reclined too far back.
RYour arms should be slightly bent when you
are holding the steering wheel.
RAvoid seat positions that prevent the seat belt
from being correctly routed. The shoulder
section of the belt must be routed over the
middle of your shoulder and be pulled tight
against your upper body. The lap belt must
always pass across your lap as low down as
possible, i.e. over your hip joints.
RAdjust the head restraint so that it supports
the back of the head at eye level.
RThe distance from the pedals should be such
that you can depress them fully.

Replacing bulbs
Important safety notes
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
!Make sure the bulbs are always securely
installed.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore make
sure that these function correctly at all times.
Have the headlamp setting checked regularly.
RAlways switch off the ignition before replacing bulbs in the lighting system. This will prevent
a short circuit.
RWear gloves and eye protection when chang-
ing a bulb.
RDo not use a bulb that has been dropped or
that has scratches on its glass tube. The bulb
could may explode.
RA bulb could explode if:
-you touch it
-it is hot
-you drop it
-you scratch or score it
RMarks on the glass tube shorten the operating
life of a bulb. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit. Then rub
off the glass tube with a clean, lint-free cloth.
RMake sure that bulbs are protected from
moisture when operating and that they do not
come into contact with liquids. Make sure
that seals are seated correctly and replace
damaged seals.
RCheck the contacts for signs of corrosion and
clean these if required.
ROnly operate bulbs in closed lamps which
have been designed for this purpose.
ROnly use spare bulbs of the same type, with
the prescribed voltage and the correct wat-
tage.
RIf the new bulb does not light up, consult a
qualified specialist workshop.
RHave lamps with LED bulbs repaired at a quali- fied specialist workshop only.
RHave the bulbs of the following lamps
replaced at a qualified specialist workshop
only:
-the additional brake lamps
-the license plate lighting
-Front fog lamps
-side marker lamp

cally if you engage reverse gear and the wind-
shield wipers are on.
If the vehicle is stationary and you open the tail-
gate or rear door, the rear window wiper will
stop automatically. The rear window wiper will
only resume wiping again when the tailgate and
rear door are closed and you pull away again.
The rear window will no longer be wiped properly if the wiper blade is worn. This may prevent you
from observing the traffic conditions. Informa-
tion on replacing the wiper blade can be found
under "Replacing wiper blades" (
Ypage 107).
Replacing the wiper blades
Important safety notes
GWARNING

!Never open the hood/tailgate or rear doors
if a windshield wiper arm has been folded
away from the windshield/rear window.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiper blade
and it falls onto the windshield/rear window,
the windshield/rear window may be damaged
by the force of the impact. Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
!Only hold the wiper blade by the wiper arm.
You could otherwise damage the wiper rub-
ber.
Wiper blades are wear parts. The windshield will
no longer be wiped properly if the wiper blades
are worn. This may prevent you from observing
the traffic conditions.
