Window curtain air bagsGWarning
Observe "Important safety notes"
(Y page 38).
The window curtain air bags enhance the level
of protection for the head (but not chest or
arms) of the vehicle occupants on the side of
the vehicle on which the impact occurs.
The window curtain air bags are integrated
into the side of the roof frame and deploy in
the area extending from the front door (A-
pillar) to the rear door (C-pillar).
Example: Sedan
Window curtain air bags : are deployed:
Ron the side on which an impact occurs
Rat the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
Rregardless of whether the front-passenger
seat is occupied
Rindependently of seat belt use
Rif the vehicle overturns and the system
determines that window curtain air bag
deployment can offer additional protection
to that provided by the seat belt
Rindependently of the front air bags
Window curtain air bags : will not deploy in
impacts with deceleration rates which do not
exceed the system’s preset deployment
thresholds for vehicle deceleration or
acceleration. You will then be protected by
the seat belt.
Occupant classification system (OCS)
How the Occupant Classification
System works
The Occupant Classification System (OCS) is
standard equipment in the USA.
OCS categorizes the occupant on the front-
passenger seat by means of a weight sensor.
The front-passenger front air bag is
automatically deactivated for certain weight
categories. The respective status can be
recognized by the 45 indicator lamp.
With the 45 indicator lamp
illuminated, the front-passenger front air bag
is deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe pelvis air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
Rwith the seat belt properly fastened
Rin a position that is as upright as possible
with the back against the seat backrest
Rwith their feet on the floor
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by
leaning on armrests), OCS may not be able to
approximate the occupant's weight category.
If the front passenger seat, the seat cover, or
the seat cushion are damaged, have the
necessary repair work carried out at an
authorized Mercedes-Benz Center.
For reasons of safety, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should observe the 45 indicator lamp
to determine whether or not the front
passenger is positioned correctly.
Occupant safety43SafetyBA 212 USA, CA Edition B 2011; 1; 5, en-USdimargiVersion: 3.0.3.62010-05-20T13:33:46+02:00 - Seite 43Z

Example: Sedan
XAdjust the seat and move the backrest to
an almost vertical position (Y page 102).
XPull the seat belt smoothly through belt
sash guide :.
XWithout twisting it, guide the shoulder
section of the seat belt across the middle
of your shoulder and the lap section across
your hips.
XEngage belt tongue ; in buckle =.
Seat belt adjustment: if necessary, the
driver's and front-passenger seat belts
automatically adjust to the upper body
(Y page 56).
XIf necessary, adjust the seat belt to the
appropriate height (Y page 56).
XIf necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
All seat belts in the vehicle, except the
driver's seat belt, are equipped with a special
seat belt retractor to secure child restraint
systems properly. For further information on
"Special seat belt retractors", see
(Y page 61).
For more information about releasing the seat
belt with release button ?, see "Releasing
seat belts" (Y page 57).
Seat belt adjustment
The seat-belt adjustment function adjusts the
driver's and front-passenger seat belt to the
upper body of the occupants.
The belt strap is tightened slightly when:
Ryou engage the belt tongue in the belt
buckle and you then turn the SmartKey to
position 2 in the ignition lock.
Rthe SmartKey is in position 2 in the ignition
lock and you then engage the belt tongue
in the buckle.
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. You can switch the seat-belt
adjustment on and off in the on-board
computer (Y page 233).
Seat belt outlet height adjustment
You can adjust the seat belt height on the
driver's seat and the front-passenger seat.
Wagon: you can also adjust the belt height
on the outer rear seats.
Adjust the height so that the upper part of the
seat belt is routed across the center of your
shoulder.
XTo raise: slide the belt sash guide upwards.
The belt sash guide engages in various
positions.
XTo lower: press and hold belt sash guide
release :.

The ! warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Braking
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
XIf ABS intervenes: continue to depress the
brake pedal with force until the braking
situation is over.XTo make a full brake application:
depress the brake pedal with full force.GWarning
If the ABS malfunctions, other driving systems
such as the BAS or the ESP ®
are also switched
off. Observe indicator and warning lamps that
may come on as well as messages in the
multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
BAS (Brake Assist)
GWarning
Observe "Important safety notes"
( Y page 65).
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
XKeep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
GWarning
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
BAS PLUS (Brake Assist PLUS)
GWarning
Observe "Important safety notes"
( Y page 65).
At speeds above approximately
20 mph (30 km/h), BAS PLUS assists you
when braking in hazardous situations and
uses the radar sensor system to evaluate the
traffic conditions.
GWarning!
BAS PLUS is a convenience system designed
to assist the driver during vehicle operation.
The responsibility for the vehicle speed and
the distance to the vehicle ahead, including
most importantly brake operation to assure
safe stopping distance, always remains with
the driver.
Always pay attention to traffic conditions
even while BAS PLUS is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident. Personal or fatal
injury to you or others may be the result.
i This equipment has been approved by the
FCC as a "Vehicular Radar System". The
radar sensor system is intended for use in
an automotive radar system only. Removal,
tampering, or altering of the device will void
any warranties, and is not permitted by the
FCC. Do not tamper with the device in any
way.
Any unauthorized modification to this
device could void the user's authority to
operate the equipment.

BA 212 USA, CA Edition B 2011; 1; 5, en-USdimargiVersion: 3.0.3.62010-05-20T13:33:46+02:00 - Seite 66

BAS PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time. Should you approach a detected
obstacle quickly, BAS PLUS calculates the
braking force necessary to avoid a rear-end
collision. Should you additionally apply the
brakes, BAS PLUS will automatically increase
the braking force to a level suitable for the
traffic conditions.
If BAS PLUS demands particularly high
braking force, PRE-SAFE ®
is activated
simultaneously.XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again when:
R you release the brake pedal
R no obstacle is detected in front of your
vehicle
R there is no longer any danger of a rear-end
collision
BAS PLUS is then deactivated.
At speeds up to approximately
40 mph (70 km/h), BAS PLUS can also detect
stationary obstacles, for example, stopped or
parked vehicles.
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational. You can check this by activating
DISTRONIC PLUS ( Y page 179) or via the
"radar sensor" function in the on-board
computer( Y page 232).
GWarning!
BAS PLUS will only respond with brake
assistance if it has clearly detected an object.
Detection can be impeded by
R dirty or covered sensors
R snowfall or heavy rain
R disturbance from other radar sources
R strong radar reflection such as in parking
garages
BAS PLUS uses radar signals that are not
reflected well by narrow objects and
absorptive materials. For this reason BAS
PLUS will not react to persons, animals, and
approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles
driving in front of you, such as motorcycles
and vehicles driving offset from your vehicle
center.
Following a collision or accident-related
damage to the front end of the vehicle, have
the configuration and operation of the radar
sensors checked at an authorized Mercedes-
Benz Center.
If BAS PLUS is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.
ESP ®
(Electronic Stability Program)
Important safety notes
GWarning
Observe "Important safety notes"
( Y page 65).
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or
slippery roads. ESP ®
can also stabilize the
vehicle during braking.
If ESP ®
intervenes, the ä warning lamp
flashes in the instrument cluster.
