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 in (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 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 air bag 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 air bag inflates.
This could result in serious injuries or
death should the air bag be triggered.
Always sit nearly upright, properly use
the seat belts and appropriate size in-
fant or child restraint system.


Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM1
compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger front air bag when it
is properly installed. Otherwise they will
be struck by the air bag 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, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this Op-
erator’s Manual.

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 front passenger
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front air bag.
BabySmart
TM will not, however, turn off any
side impact air bag.
It should be noted that with respect to both
front and rear side impact air bags there is a
possibility for a side air bag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
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) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side air bag inflates. This could result in

Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.The ETD is designed to activate in the fol-
lowing cases:


in frontal or rear-end impact exceeding
a preset severity level


in certain vehicle rollovers


if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 60)
In an impact, emergency tensioning devic-
es remove slack from the belts in such a
way that the seat belts fit more snugly
against the body. Belt force limiters reduce
the force exerted by the seat belts on oc-
cupants during a crash.


Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another per-
son or other objects.


Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to manage impact forces. The
twisted belt against your body could
cause injuries.


Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.


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.
iThe ETDs for the front seats will only
activate if the respective front seat belt
is fastened (latch plate properly insert-
ed into buckle).
The ETDs for the rear outer seats will
activate with or without the respective
seat belt fastened.
Warning!
G
A pyrotechnic emergency tensioning device
(ETD) that was activated must be replaced.
When disposing of the pyrotechnic emer-
gency tensioning device, our safety instruc-
tions must be followed. These are available
at your authorized Mercedes-Benz Center.
PRE-SAFE
® has electrically operated revers-
ible pre-tensioners that do not require
replacement after activation.
!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact air bag on the front passenger
side and, with the seat belt fastened to
secure the object, the ETD to deploy in
a crash which exceeds the system’s de-
ployment threshold.

70 Safety and SecurityOccupant safetyAutomatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats and for the rear outer seats (only for
vehicles with electrically adjustable rear
bench seat* or with individual seats* in the
rear) reduces the retracting force of the
seat belts when they are in normal use.
Preventive occupant safety (PRE-SAFE
®)Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:


You execute an emergency braking ma-
neuver and the Brake Assist System
(page 80) is activated.


The PRE-SAFE
® system detects a criti-
cal driving dynamics situation.
In such cases, the following systems are
automatically activated:


A front seat belt with the seat belt
buckled is pre-tensioned electrically.


If the occupied front passenger seat or
rear seats are in an unfavorable posi-
tion, they are adjusted to a better posi-
tion. Rear seat adjustment occurs only
in ve hic le s wi th ind ivid ua l s ea ts* i n the
rear.


The tilt/sliding sunroof closes if the ve-
hicle is in a severe skid or is spinning.If the seat belts do not release:

Adjust the backrest or seat slightly to
the rear until the seat belt tension is di-
minished.
The locking mechanism releases.
Warning!
G
The PRE-SAFE
® system is intended to re-
duce the effects of an accident on properly
seat-belted vehicle occupants. Despite hav-
ing the PRE-SAFE® system in your car, the
possibility of injuries occurring as a result of
an accident cannot be totally eliminated.
Therefore you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
iThe PRE-SAFE
® systems are activated
in the previously described circum-
stances only at speeds exceeding
22 mph (35 km/h).
When the driving dynamic situation has
passed without an accident occurring,
the pre-tensioning on the seat belts is
deactivated.
You can then adjust the seats and the
tilt/sliding sunroof to their previous po-
sition.

ESP
® (E

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 ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
The - indicator lamp in the instrument
cluster (
page 24) comes on when you
switch on the ignition (
page 34). It goes
out when the engine is running.
iIn winter operation, the maximum ef-
fectiveness of the ABS, ESP
®, BAS and
4MATIC is only achieved with winter
tires (
page 327), 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 4MATIC cannot re-
duce 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.

ESP
®
The Electronic Stability Program (ESP
®) is
operational as soon as the engine is run-
ning and 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 the engine output, the ESP
®
works to stabilize the vehicle. The ESP® is
especially useful while driving off and on
wet or slippery road surfaces. The ESP®
also stabilizes the vehicle during braking
maneuvers.
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 comes on when you switch on
the ignition (
page 34). 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 afforded. 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
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 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 result-
ing from excessive speed.

82 Safety and SecurityDriving safety systems
For more information, see “Practical hints”
(page 344).Switching off the ESP
®
To improve the vehicle’s traction, switch
off the ESP
® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:


starting out on slippery surfaces and in
deep snow in conjunction with snow
chains


in sand or gravel
Warning!
G
The ESP
® cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
®
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP
® 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.
iDistronic* is switched off when the
ESP
® engages.
iThe ESP
® will only function properly if
you use wheels of the recommended
tire size (page 426).
!Because of the ESP’s
® automatic oper-
ation, 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/rear axle raised
Active braking action through the ESP
®
may otherwise seriously damage the
brake system.
Warning!
G
The ESP
® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
iDistronic* cannot be activated when
the ESP
® has been switched off.
