Seats
75Seats
Depending on the vehicle's equipment, seat
adjustments can be made either manually/
electrically or electrically*. G
Risk of injury
The seats can still be adjusted when there
is no key in the ignition lock. For this rea-
son, children should never be left unsuper-
vised in the vehicle. They could become
trapped by a seat adjustment movement. G
Risk of accident
Only adjust the driver's seat when the vehi-
cle is stationary. You will otherwise be dis-
tracted from the road and traffic conditions
and you could lose control of the vehicle as
a result of the seat moving. This could
cause an accident. G
Risk of injury
Make sure that nobody can become trap-
ped as you adjust the seat.
Observe the notes concerning the airbag
system.
Secure children as recommended; see the
"Children in the vehicle" section. !
When you move the seats, make sure that
there are no objects in the footwell or
behind the seats. Otherwise, you could
damage the seats and the objects.
i The head restraints in the front seats are
fitted with the NECK-PRO system
(Y page 49). For this reason, it is not pos-
sible to remove the head restraints from
the front seats.
For design reasons, the rear-compartment
head restraints cannot be removed.
Please contact a Mercedes-Benz Service
Centre for more information. Adjusting the seats manually and

Seat belts
88 Seat belts
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 belt
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, push down the belt strap
slightly

and then retighten it in the roll-up
direction.
R Do not route the belt strap across sharp
or fragile objects, especially if these are
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. Children must never
travel sitting on the lap of other occu-
pants. It would not be possible to restrain
the child in the event of a sudden change
in direction, braking or an accident. This
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, suitable
restraint systems.
R Children less than 1.50 m tall or under
12 years of age cannot wear the seat
belts 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 fatal
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 belt
that has been subjected to a load in an
accident or modified no longer offers the
intended level of protection. Under certain
circumstances this could cause severe or
even fatal injuries. Controls

Risk of injury
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. The children could:
R be seriously or even fatally injured on
parts of the vehicle
R be seriously or even fatally injured by
prolonged exposure to extremely high or
extremely low temperatures
If children open a door, they could:
R seriously or even fatally injure other peo-
ple
R get out of the vehicle, thereby injuring
themselves or be seriously or even fatally
injured by a passing vehicle
Activate the child-proof locks if children are
travelling in the vehicle. They could other-
wise open doors or windows while the vehi-
cle is in motion and thereby injure them-
selves or others.
i It is also possible to open and close the
side windows from the outside using the
"Summer opening" (Y page 100) and "Con-
venience closing" (Y page 100) features
respectively. You can disable the controls for the rear
side windows from the driver's seat
(Y page 49).
The switches for all side windows are located
on the driver's door. There is also a switch on
each door for the respective window.Switches on the driver's door

X Make sure that the key is in position 2 in
the ignition lock.
i When the key is turned to position 0 or
removed from the ignition lock, it is still
possible to operate the windows until the driver's or front-passenger door is opened,
but for no more than five minutes.
X To open or close: press the switch down

pull it up.
Closing with increased force and without
the anti-entrapment feature
G Risk of injury
Make sure that nobody can become trap-
ped and a serious or even fatal injury is not
caused as you close a side window with
increased force or without the anti-entrap-
ment feature.
If a side window locks up during closing and
has reopened again slightly:
X Immediately after the window locks up, pull
the switch upwards until the window is fully
closed.
The side window is closed with more force.

G
Risk of accident
Do not keep any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that they are
correctly secured and that there is suffi-
cient clearance for the pedals.
Objects could otherwise get between the
pedals in the event of sudden braking or
acceleration. You may then no longer be
able to brake, change gear or accelerate as
intended. This may result in an accident and
injury. G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.
! Do not depress the accelerator pedal
when starting the engine.
i If you depress the brake when starting the
engine, pedal travel will be unusually long
and there will be less pedal resistance. Controls

G
Risk of accident and injury
An incorrectly secured roof rack, ski rack
or load could work loose from the vehicle.
These objects may then be thrown around
and can injure you or others or cause an
accident. Follow the roof rack/ski rack
manufacturers' installation instructions
and special instructions for use.
The roof load raises the vehicle's centre of
gravity, thereby affecting vehicle handling.
You must always observe the maximum
roof load of 100 kg. Always adapt your driv-
ing style to the prevailing road, traffic and
weather conditions and drive with particu-
lar care if the roof is laden.
! Mercedes-Benz recommends that you
only use roof rack systems which have been tested and approved for Mercedes-
Benz vehicles. This helps to prevent dam-
age to the vehicle.
Position the load on the roof rack in such a
way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle's equipment,
make sure that you can:
R
raise the sliding/tilting sunroof* fully
R open the boot lid fully 1
