42 Safety and Security
Occupant safety
Air bags
Warning!G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal im-
pacts (front air bags, driver-side knee bag),
side impacts (side impact air bags and win-
dow curtain air bags) or rollovers (window
curtain air bags). However, no system avail-
able today can completely eliminate injuries
and fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle
as soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get
fresh air by opening a window or door.
Warning!G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear their
respective seat belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and make sure that it is prop-
erly positioned on your body (
page 360).
Since the air bag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:
Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.
Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Center.
Do not lean your head or chest close to
the steering wheel or dashboard.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver’s front air bag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.

Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
air bag
Warning!G
Damaged seat belts or seat belts that
were highly stressed in an accident
must be replaced and their anchoring
points must also be checked. Only use
seat belts installed or supplied by an au-
thorized Mercedes-Benz Center.
Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) are designed
to function on a one-time-only basis. An
air bag or ETD that is deployed must be
replaced.
Do not pass seat belts over sharp edges.
They could tear.
Do not make any modification that could
change the effectiveness of the seat
belts.
Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.
No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, front passenger front air bag
cover, outboard sides of the seat back-
rests, door trim panels, or door frame
trims, and installation of additional
electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).
Do n o t h a ng i te ms su ch as c o at ha n ger s
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when the window curtain air bag is
deployed.
Air bag system components will be hot
after an air bag has inflated. Do not
touch.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
For your protection and the protection
of others, when scrapping the air bag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Center.

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.
