Seat belts are the most effective means of
restraining the movement of vehicle occu-
pants in the event of an accident. This
reduces the risk of vehicle occupants coming
into contact with the vehicle interior. Wearing seat belts
G
Risk of injury
A seat belt which is not worn correctly, or
which has not been engaged in the seat bel t
buckle correctly, cannot perform its inten-
ded protective function. Under certain cir-
cumstances this could cause severe or
even fatal injuries.
Make sure that all occupants – in particular,
pregnant women – wear their seat belt cor-
rectly at all times .
R The seat belt must pass closely over your
body and must not be twisted. You
should therefore avoid wearing bulky
clothing (e.g. a winter coat). The shoulder
belt section must be routed across the
middle of your shoulder – on no account
across your neck or under your arm – and
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 – not across your abdomen. If
necessary, tighten the belt strap by pull-
ing it down slightly and retighten in the
direction of the inertia reel.
R Do not route the belt strap across sharp
or fragile objects, especially if these ar e
located on or in your clothing, e.g. spec -
tacles, pencils, keys, etc. The seat belt
strap could be damaged and tear in an
accident and you or other vehicle occu -
pants could be injured.
R Only one person should use each seat
belt at any one time. On no account
should children travel sitting on your lap
or the lap of another occupant, as it
would not be possible to restrain the
child in the event of an accident, braking
or a sudden change in direction, which
could result in severe or even fatal inju-
ries to the child and other occupants.
R Persons less than 1.50 m tall cannot
wear the seat belts correctly. For this
reason, secure persons less than 1.50 m
tall in specially designed, suitabl e
restraint systems .
R Children less than 1.50 m tall or under
12 years of age cannot wear the seat Control

99belts properly. Therefore, always secure
these children in suitable child restraint
systems on suitable vehicle seats. You
can find more information under "Chil-
dren in the vehicle" in the "Safety" sec-
tion of the Owner's Manual. Follow the
manufacturer's installation instructions
when fitting the child restraint system .
R Do not secure any objects with a seat belt
if the seat belt is also being used by one
of the vehicle's occupants. G
Risk of injury
The seat belt does not offer the intended
level of protection unless the backrest is
almost vertical. Under certain circumstan-
ces this could cause severe or even fata l
injuries.
Before starting a journey, make sure that
the seat is properly adjusted and that the
backrest is almost vertical. G
Risk of injury
A dirty or damaged seat belt or a seat bel t
that has been subjected to a load in an
accident or modified no longer offers the
intended level of protection. Under certai n circumstances this could cause severe or
even fatal injuries.
For this reason, check regularly that the
seat belts are not damaged or dirty.
Always have damaged seat belts or sea t
belts that have been subjected to a load in
an accident replaced at a qualified special-
ist workshop. Choose a qualified specialist
workshop which has the necessary special-
ist knowledge and tools for the work
required. Mercedes-Benz recommends
that you use a Mercedes-Benz Service
Centre for this purpose.
For safety reasons, Mercedes-Benz recom -
mends that you only use seat belts which
have been approved by Mercedes-Benz for
your vehicle. 1

Sliding sunroof
173Rear window heating
G
Risk of accident
Clear all windows of ice or snow before set-
ting off. Impaired visibility could otherwise
endanger yourself and others.
i The rear window heating has a high cur-
rent draw. Therefore, switch it off as soon
as the rear window is free of snow and ice,
as it only switches itself off automatically
after between fifteen and thirty minutes.
i If the battery voltage is too low, the rear
window heating may switch off.
X Make sure that the key is in position 2in
the ignition lock .
X To switch on/off :press the ¯button.
The indicator lamp in the ¯switch is lit

G
Risk of injury
Never leave children unsupervised in the
vehicle. They could operate the sliding/tilt-
ing sunroof and injure themselves. Alway s
take the key with you when leaving the
vehicle, even if you only leave it for a short
time. G
Risk of injury
Make sure that nobody can become trap -
ped when you are opening and closing the
sliding/tilting sunroof. If danger threatens,
release the switch and push it briefly in any
direction to stop the sliding/tilting sunroof . G
Risk of injury
The glass in the sliding/tilting sunroof
could break in an accident. If you are not
wearing a seat belt, there is a risk that yo u
could be thrown through the opening in the
event of the vehicle overturning. Therefore,
always wear a seat belt to reduce the ris k
of injuries. !
Only open the sliding/tilting sunroof if it
is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the slid -
ing/tilting sunroof is open. They are caused
by minor pressure fluctuations in the vehi-
cle interior .
Change the position of the sliding/tilting
sunroof or open a side window slightly to
reduce or eliminate these noises .
i It is also possible to open and close the
sliding/tilting sunroof from the outsid e
using the "Summer opening" (Y page 111 )
and "Convenience closing" (Y page 112 )
features respectively .
i If PRE-SAFE ®
has been activated, the slid-
ing/tilting sunroof closes automatically ,
leaving a small gap open . Cont
