30 Getting startedUnlockingThe "Getting started" section provides an
overview of the vehicle’s most basic func-
tions. First-time Mercedes-Benz owners
should pay special attention to the infor-
mation given here.
If you are already familiar with the basic
functions described here, the "Controls in
detail" section will help you with further in-
formation. The corresponding page refer-
ences are at the end of each segment.

59 Safety and Security
Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
airbag
iAirbags are designed to activate only in
certain frontal impacts (front air bags),
side impacts (side impact and head
protection window curtain airbags)
which exceed preset thresholds and in
rollovers (head protection window cur-
tain airbags). Only during these events
will they provide their supplemental
protection.
The driver and passengers should al-
ways wear their seat belts. Otherwise it
is not possible for airbags to provide
their supplemental protection.
In case of other types of impacts and
impacts below air bag deployment
thresholds, airbags will not be activat-
ed. The driver and passenger will then
be protected to the extent possible by
a properly fastened seat belt. A proper-
ly fastened seat belt is also needed to
provide the best possible protection in
a rollover.
We caution you not to rely on the pres-
ence of the airbags in order to avoid
wearing your seat belt.
Your vehicle was originally equipped
with airbags that are designed to acti-
vate in certain impacts exceeding a
preset threshold to reduce the poten-
tial and severity of injury. It is important
to your safety and that of your passen-
gers that you replace deployed airbags
and repair any malfunctioning airbags
to ensure that the vehicle will continue
to provide supplemental crash protec-
tion for occupants.
Warning!
G


Damaged seat belts or belts that were
highly stressed in an accident must be
replaced and their anchoring points
must also be checked. Use only belts in-
stalled or supplied by an authorized
Mercedes-Benz Center.


Airbags and ETDs are designed to func-
tion on a one-time-only basis. An airbag

ABS
The 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 ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure.
If the ABS activates during braking, the
ESP warning lamp v in the instrument
cluster dial flashes. Because of the SBC
brake system, you will not feel any pulsa-
tion in the brake pedal.
iIn winter operation, the maximum ef-
fectiveness of the ABS and the ESP is
only achieved with winter tires (M + S
tires), or snow chains as required.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The ABS, BAS, ESP and SBC cannot reduce
this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
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.

74 Safety and SecurityDriving safety systemsContinuos steady brake pedal pressure
yields the advantagesprovided by the ABS,
namely braking power and ability to steer
the vehicle.
The - warning lamp in the instrument
cluster lights up when you turn the key in
the starter switch to position2 or press
the KEYLESS-GO* (if so equipped)
start/stop button twice. It goes out when
the engine is running.
More information can be found in the
"Practical hints" section (
page 289).
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing the braking distance. Apply
continuous full braking pressure until the
emergency braking situation is over. The
ABS will prevent the wheels from locking.
When you release the brake pedal, the
brakes function again as normal. The BAS
is then deactivated.
iTo alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as appro-
priate.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction. The
ABS cannot prevent accidents, including
those resulting from excessive speed in
turns, following another vehicle too closely,
or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ABS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.

75 Safety and Security
Driving safety systems
ESP
The Electronic Stability Program (ESP)
monitors the vehicle's traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting engine output, the ESP works to
stabilize the vehicle. The ESP is especially
useful during take-off and on wet or slip-
pery road surfaces.
The ESP warning lamp v in the instru-
ment cluster flashes when the ESP is en-
gaged.
The ESP warning lamp v in the instru-
ment cluster lights up when you turn the
key in the starter switch to position2 or
press the KEYLESS-GO* (if so equipped)
start/stop button twice. It goes out when
the engine is running.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that af-
forded by the condition of the vehicle brakes
and tires or the traction. The BAS cannot
prevent accidents, including those resulting
from excessive speed in turns, following an-
other vehicle too closely, or aquaplaning.
Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of a BAS
equipped vehicle must never be exploited in
a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
Warning!
G
Never switch off the ESP when you see the
ESP warning lamp
v
flashing in the in-
strument cluster. In this case proceed as fol-
lows:


While driving off, apply as little throttle
as possible


While driving ease up on the accelerator


Adapt your speed and driving style to
the prevailing road conditions
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.
