53 Safety and Security
Occupant safety
Warning!G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the belt is properly positioned
on the body.
Warning!G
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Never use a seat belt for more than one per-
son at a time.
Warning!G
Damaged seat belts or seat belts that were
highly stressed in an accident must be re-
placed and their anchoring points must also
be checked.
Only use seat belts which have been
approved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to failure.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
Warning!G
USE SEAT BELTS PROPERLY
Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.
Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver air bag,
driver-side knee bag, passenger front air
bag, side impact air bags, window cur-
tain air bags for side windows), ETD
(seat belt emergency tensioning device
with seat belt force limiters), and front
seat knee bolsters. The system is de-
signed to enhance the protection of-
fered to properly belted occupants in
certain frontal (front air bags, driver-side
knee bag and ETD with seat belt force
limiters) and side (side impact and win-
dow curtain air bags) impacts
56 Safety and Security
Occupant safety
Preventive occupant safety
(PRE-SAFE®)
Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations.PRE-SAFE
® takes action in the following in-
stances:
Emergency braking maneuver and the
Brake Assist System (BAS) (
page 66)
is activated
or when
BAS Plus* (
page 67) is strongly inter-
vening.
Critical dynamic driving situations, e.g.
when the vehicle is understeering or
oversteering because it has exceeded
its physical limitations.
Evasive steering maneuvers at speeds
above 20 mph (30 km/h).
When you are driving faster than 20 mph
(30 km/h), PRE-SAFE
® takes the following
measures in such situations:
If the OCS senses that the front pas-
senger seat is occupied and the seat is
in an unfavorable position, it will be
adjusted to a better position.
The system increases the air pressure
in the air pockets (on the sides of the
seat cushion and backrest) of the
drive-dynamic multicontour front
seats*.
If the vehicle is understeering or over-
steering, the tilt/sliding sunroof and
the front side windows also close until
only a small gap remains.
Once the hazardous situation is over with-
out an accident occurring, PRE-SAFE
® de-
creases the air pressure in the air pockets
of the drive-dynamic multicontour front
seats*. You can readjust all of the settings
made by PRE-SAFE
®.
Warning!G
The PRE-SAFE® system is intended to re-
duce the effects of an accident on properly
seat-belted vehicle occupants. Despite
having the PRE-SAFE
® system in your vehi-
cle, the possibility of injuries occurring as a
result of an accident cannot be eliminated.
Therefore, you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
iIf the closing procedure of the tilt/sliding
sunroof or door windows is blocked, the tilt/slid-
ing sunroof or door windows will stop and open
slightly.

Warning!G
Activate the override switch when children
are riding in the back seats of the vehicle.
The children may otherwise injure them-
selves, e.g. by becoming trapped in the win-
dow opening.

the vehicle. The children may otherwise in-
jure themselves, e.g. by becoming trapped
in the window opening.
The closing of the side 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 a door 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.
If a door window encounters an obstruction
that blocks its path in a circumstance where
you are closing the window by pressing and
holding the switch, by pressing and holding
button ‹ on the SmartKey or SmartKey
with KEYLESS-GO*, by pressing and holding
the sensor surface (vehicles with
KEYLESS-GO*) on an outside door handle,
or by pressing and holding button, on
the climate control panel, the automatic re-
versal function will not operate.
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

562 Operation
Vehicle care
Cleaning the windows and the wiper
blades
Make sure the hood is fully closed.
Placing wiper arms in vertical position
Vehicles with SmartKey:
Turn SmartKey in starter switch
position1.
Turn combination switch to wiper
settingu (
page 372).
With wiper arm in vertical position, turn
the SmartKey in starter switch to
position0.
Vehicles with KEYLESS-GO*:
Make sure the vehicle’s on-board elec-
tronics have status 1 (
page 337).
Turn combination switch to wiper
settingu (
page 372).
Press KEYLESS-GO start/stop button
repeatedly until windshield wipers
start.
Press KEYLESS-GO start/stop button
when the wiper arms are in a vertical
position.
Cleaning
Fold the wiper arms forward until they
snap into place.
Clean the wiper blade inserts with a
clean cloth and detergent solution.
Use a soft, clean cloth and a mild win-
dow cleaning solution on all outside
and inside glass surfaces.
An automotive glass cleaner is recom-
mended.
!The windshield wipers must be in a vertical
position before folding them away from the wind-
shield. They could otherwise damage the hood.
Never open the hood when the wiper arms are
folded forward.
Warning!G
For safety reasons, switch off wipers and re-
move SmartKey from starter switch (vehi-
cles with KEYLESS-GO*: Make sure the
vehicle’s on-board electronics have
status0) before cleaning the windshield
and/or the wiper blades. Otherwise, the
wiper motor could suddenly turn on and
cause injury.
!Do not pull on the wiper blade inserts. They
could tear.
!Fold the windshield wiper arms back onto
the windshield before turning the SmartKey in
the starter switch or pressing the KEYLESS-GO*
start/stop button (vehicles with KEYLESS-GO*).
Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.
!To clean the window interior, do not use a
dry cloth, abrasives, solvents or cleaners con-
taining solvents. Do not touch the inside of the
front, rear or side windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.
