Proper use of seat belts

Do not twist the seat belt when fasten-
ing.

Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the seat belt under
your arm.

Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.

Place the seat backrest in a nearly up-
right position.

Never use a seat belt for more than one
person at a time.

Do not fasten a seat belt around a per-
son and another object at the same
time. When using a seat belt to secure
infant restraints or toddler restraints or
children in booster seats, always follow
the child seat manufacturer’s instruc-
tions.
Warning!G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section.

5Left rear door window
Warning!G
Do not keep any part of your body up against
the side window pane when opening a win-
dow. The downward motion of the pane may
pull that part of your body down between
the window pane and the door frame and
trap it there. If there is a risk of entrapment,
release the switch and press it again to
close the window.
Warning!G
When closing the windows, make sure there
is no danger of anyone being harmed by the
closing procedure.
Activate the override switch (
page 57)
when children are riding in the back seats of
the vehicle. The children may otherwise in-
jure themselves, e.g. by becoming trapped
in the window opening.
The closing of the door windows can be im-
mediately halted by releasing the switch or,
if the switch was pressed past the resis-
tance point and released, by pressing the
lower part of the respective switch again.
The door windows are equipped with the ex-
press-close and automatic reversal func-
tion. If the window encounters an
obstruction that blocks its path in a circum-
stance where you pressed the switch past
the resistance point and released it to close
the window, the automatic reversal function
will stop the window and open it slightly.

When closing the tilt/sliding sunroof, make
sure there is no danger of anyone being
harmed by the closing procedure.
If the tilt/sliding sunroof is blocked while
closing and reopens, it can be closed with
greater force if you pull the switch to the re-
sistance point in the direction indicated by
arrow
3 within 2 seconds.
If the tilt/sliding sunroof is blocked again
and reopens, you can close it with deactivat-
ed obstruction sensor function by pulling
the switch again to the resistance point in
the direction indicated by arrow
3 within 2
seconds.

the obstruction sensor function deactivated,
make sure no one can become trapped, as
this could result in serious or fatal injuries.
The opening/closing procedure of the
tilt/sliding sunroof can be immediately halt-
ed by releasing the switch or, if the switch
was moved past the resistance point and re-
leased, by moving the switch in any direc-
tion.
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts
properly as entire body parts or portions of
them may protrude from the passenger
compartment.When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.
!To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding sunroof.
Do not open the tilt/sliding sunroof if there is
snow or ice on the roof, as this could result in
malfunctions.
!Please keep in mind that weather conditions
can sometimes change rapidly. Make sure to
close the tilt/sliding sunroof when leaving the
vehicle. If water enters the vehicle interior, vehi-
cle electronics could be damaged which is not
covered by the Mercedes-Benz Limited
Warranty.

sult in an opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly

port any objects with sharp edges which can
stick out of the tilt/sliding panel.
Do not open the tilt/sliding panel if there is snow
or ice on the roof, as this could result in malfunc-

iWhen the panorama roof with power
tilt/sliding panel is open, resonance noises may
result in addition to the usual wind noises. They
are caused by minimal pressure changes in the
passenger compartment. To reduce or eliminate
these noises, change the position of the panora-
ma roof with power tilt/sliding panel or open a
side window slightly.

panel using the SmartKey, see “Summer open-
ing feature” (

bag off indicator lamp does
not illuminate and/or does
not remain illuminated with
the weight of a typical
12-month-old child in a stan-
dard child restraint or less on
the front passenger seat.The system is malfunctioning.Make sure there is nothing between seat cushion
and child seat and check installation of the child
seat.
Make sure no objects applying supplemental
weight onto the seat are present.

Front Passenger
Airbag Enabled
See Operator’s Manu-
alFront passenger front air bag is
activated while driving even
though a child, small individual,
or object below the system’s
weight threshold is on the front
passenger seat, or the front pas-
senger seat is empty. Objects
on the seat or forces acting on
the seat may make the system
sense supplemental weight.Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Switch off the ignition (page 82).
Remove child and child restraint from front passenger seat and properly
secure the child in rear seat employing the child restraint if necessary.
Make sure no objects which apply forces to the seat are present (e.g.
objects such as books, briefcases etc. lodged behind or around the
seat, head restraints pushing against roof, etc.). The system may recog-
nize such forces as supplemental weight and sense that an occupant on
the front passenger seat is of a greater weight than actually present.
Keep the seat unoccupied, close the front passenger door and switch
on the ignition (
page 82).
Monitor the
5/indicator lamp right of the instrument cluster
(
