36 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), side impacts (front
side impact air bags, rear side impact air
bags* and window curtain air bags) or roll-
overs (window curtain air bags). However,
no system available today can totally elimi-
nate 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 it is properly
positioned on your body.
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 nearly upright
position 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.

37 Safety and Security
Occupant safety

Always sit as upright as possible, prop-
erly use the seat belts and use an appro-
priately sized infant restraint, toddler
restraint, or booster seat recommended
for the size and weight of the child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
Warning!G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
There is a possibility for a side impact air
bag related injury if occupants, especially
children, are not properly seated or re-
strained when next to a front side impact air
bag and/or rear side impact air bag* which
needs to deploy rapidly in a side impact in
order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Always sit as upright as possible,
properly use the seat belts, and for all
children 12 years old and under, use an
appropriately sized infant restraint, tod-
dler restraint, or booster seat recom-
mended for the size and weight of the
child.
(2) Always wear seat belts properly.iAir bags are designed to deploy only in cer-
tain frontal impacts (front air bags), and in side
impacts (front side impact air bags, rear side im-
pact* air bags, and window curtain air bags)
which exceed preset thresholds, and in certain
rollovers (window curtain air bags). Only during
these events will they provide their supplemental
protection.
The driver and passengers should always wear
their seat belts. Otherwise it is not possible for
air bags to provide their supplemental protec-
tion.
In case of other types of impacts and impacts be-
low air bag deployment thresholds, air bags will
not deploy. The driver and passenger will then be
protected to the extent possible by a properly
fastened seat belt. A properly fastened seat belt
is also needed to provide the best possible pro-
tection in a rollover.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas-
sengers that you replace deployed air bags and
repair any malfunctioning air bags to make sure
the vehicle will continue to provide supplemental
crash protection for occupants.

intensity for a maximum of 60 seconds
or until the driver’s and the front
passenger’s seat belt are fastened.
If you and/or your front passenger
release the seat belt during driving, the
seat belt telltale< starts flashing
and a warning chime sounds as
described before.
If the driver’s or the front passenger’s
seat belt remains unfastened after
60 seconds, the warning chime stops
sounding, the seat belt telltale<
stops flashing but continues to be
illuminated.
After a vehicle standstill, the warning
chime reactivates and the seat belt
telltale< flashes again when the
vehicle speed exceeds 15 mph
(25 km/h).
The seat belt telltale< will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a front door is opened.For more information, see “Practical hints”
(
page 380).
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts are equipped with Emergen-
cy Tensioning Devices (ETDs) and seat belt
force limiters.
The ETD is designed to activate in the
following cases:

in frontal or rear-end impacts exceed-
ing the system deployment threshold

in certain vehicle rollovers

if the restraint systems are operational
and functioning correctly,
see=indicator lamp (
page 382)In an impact, the ETDs remove slack from
the seat belts in such a way that the seat
belts fit more snugly against the body. Seat
belt force limiters, when activated, are em-
ployed to help reduce the peak force exert-
ed by the seat belts on occupants during a
crash.
iThe ETDs for the front seats will only acti-
vate if the front seat belt is fastened (latch plate
properly inserted into buckle).
The ETDs for the rear seats will activate with or
without the respective seat belt fastened.
iETDs do not correct an incorrect seat posi-
tion or incorrectly worn seat belts.
ETDs do not pull occupants back toward the
backrest.
Warning!G
A pyrotechnic Emergency Tensioning Device
(ETD) that was activated must be replaced.
When disposing of the pyrotechnic Emer-
gency Tensioning Device (ETD), our safety
instructions must be followed. These are
available at an authorized Mercedes-Benz
Center.

switches located in the driver’s door is still
possible.

59 Safety and Security
Driving safety systems
Driving safety systems
This section contains information about
the following driving safety systems:

ABS (Antilock Brake System)

Adaptive Brake

BAS (Brake Assist System)

EBP (Electronic Brake Proportioning)

ESP® (Electronic Stability Program)

4MATIC (Four Wheel Electronic Trac-
tion System)
ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.The ABS is functional above a speed of
approximately 5 mph (8 km/h) indepen-
dent of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The - indicator lamp in the instrument
cluster (
page 26) comes on when you
switch on the ignition. It goes out when the
engine is running.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Warning!G
The following factors increase the risk of
accidents:

Excessive speed, especially in turns

Wet and slippery road surfaces

Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or pre-
vent the natural laws of physics from acting
on the vehicle.
Always adapt your driving style to the pre-
vailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
iIn winter operation, the maximum effective-
ness of the ABS, BAS, EBP, ESP® and 4MATIC is
only achieved with winter tires (
page 360), or
snow chains as required.
Warning!G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
