58 Safety and SecurityOccupant safety

Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least 10 in
(25 cm) or more. You should be able to
accomplish this by a combination of ad-
justments to the seat and steering
wheel. If you have any problems, please
see your authorized Mercedes-Benz
Center.


Do not lean with your head or chest
close to the steering wheel or dash-
board.


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 front airbag inflates.


Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.


Occupants, especially children, should
never lean their heads in the area of the
door where the side airbag inflates. This
could result in serious injuries or death
should the airbag be triggered. Always
sit upright, properly use the seat belts
and appropriate size infant or child re-
straint system.


Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger front airbag when it
is properly installed. Otherwise they will
be struck by the airbag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle you are responsible
to make the buyer aware of these points. Be
sure to give the buyer this Operator’s Manu-
al.
Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat. Should you choose to place a child
12 years old or under in the passenger front
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front airbag.
BabySmart
TM will not, however, turn off any
side impact airbag.
It should be noted that with respect to both
front and rear side impact airbags there is a
possibility for a side airbag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
airbag which needs to deploy rapidly in a
side impact in order to do its job.


59 Safety and Security
Occupant safety
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side airbag inflates. This could result in
serious injuries or death should the side
airbag be activated
(2) Always sit upright, properly use the seat
belts and use an appropriately sized in-
fant or child restraint system for all chil-
dren 12 years old or under.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
rear seat occupants to have the rear mount-
ed side airbags deactivated, then deactiva-
tion can be accomplished upon your written
request to do so at your authorized
Mercedes-Benz Center at an additional cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
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
certain rollovers (head protection win-
dow curtain airbags). Only during these
events will they provide their supple-
mental 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.

74 Safety and SecurityDriving safety systems
Driving safety systemsIn this section you will find information on
the following driving safety systems:

ABS (A

SBC (S

4MATIC (Four Wheel Electronic
Traction 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 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.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP, SBC and 4MATIC 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, SBC and 4MATIC 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.

75 Safety and Security
Driving safety systems
The - malfunction warning lamp in the
instrument cluster comes on when you
turn the SmartKey in the starter switch to
position2 or press the KEYLESS-GO*
start/stop button twice. It goes out when
the engine is running.
Braking
If the ABS activates during braking, the
ABS/ESP warning lamp v in the instru-
ment cluster dial flashes. Because of the
SBC brake system, you will not feel any
pulsation in the brake pedal.
Keep firm and steady pressure on the
brake pedal.Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
The ABS/ESP warning lamp v flashes
whenever the ABS is activated which can
be an indication of hazardous road condi-
tions and functions as a reminder to take
extra care while driving.
Emergency brake maneuver

Keep continuous full pressure on the
brake pedal.
More information can be found in the
“Practical hints” section (
page 311).
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 hydroplaning. 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.

76 Safety and SecurityDriving safety systemsBAS
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.
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 while driving off and on wet or slip-
pery road surfaces.
The ABS/ESP warning lamp v in the
instrument cluster flashes when the ESP is
engaged.
The ABS/ESP warning lamp v in the
instrument cluster comes on when you
turn the SmartKey in the starter switch to
position2 or press the KEYLESS-GO*
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
afforded 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, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties 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
ABS/ESP warning lamp v fl as h in g i n t he
instrument cluster. In this case proceed as
follows:

While driving off, apply as little throttle
as possible.


While driving, ease up on the accelera-
tor.


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.

you use wheels of the recommended
tire size (
page 394).
!Vehicles without 4MATIC:
Because of the ESP’s automatic opera-
tion, the engine and ignition must be
shut off (SmartKey in starter switch
position0 or1 or KEYLESS-GO
start/stop button* in position0 or1)
when:

the parking brake is being tested on
a brake test dynamometer


the vehicle is being towed with the
front axle raised
Active braking action through the ESP
may otherwise seriously damage the
brake system.
