WARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed must be renewed.
For your safety, when disposing of Emergency
Tensioning Devices, always observe the
safety instructions .These are available from
any authorized Mercedes-Ben zCenter.
The PRE-SAFE ®
system has electrically
operated reversible pre-tensioners that do
not require replacement after activation.
! If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the front-
passenger seat. Otherwise, the Emergency
Tensioning Device could be triggered in the
event of an accident.
X In order to ensure that the pyrotechnic
Emergency Tensioning Devices have not
been triggered, always have the seat belts
checked after an accident.
If the Emergency Tensioning Devices have
been triggered, they must be replaced.
The seat belts on the following seats have
Emergency Tensioning Devices and belt force
limiters:
R driver's and front-passenger seat
R the outer seats in the second row
R the seats in the third row
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
If the seat belt is also equipped with a seat
belt force limiter and this is triggered, the
force exerted by the seat belt on the vehicle
occupant is reduced. The belt force limiters for the front seats are
synchronized with the fron
tair bags, which
take on a part of the deceleration force. This
results in the force exerted on the occupant
being distributed over a greater area.
The ETDs can only be activated when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 43).
R the belt tongue is engaged in the buckle on
each of the lap-shoulder belts in the front.
The belt tensioners on the outside seats in the
second row and on the seats in the third row
are triggered independently of the lock status
of the seat belts.
The ETDs are triggered depending on the type
and severity of an accident:
R if, in the event of a head-on or rear-end
collision, the vehicle decelerates or
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact
R if, in the even tofaside impact, on the side
opposite the impact the vehicle
decelerates or accelerates rapidly in a
lateral direction
R if, in certain situations where the vehicle
overturns, the system determines that it
can provide additional protection
If the ETDs are deployed, you will hear a bang,
and a small amount of powder may also be
released.O nly in rare cases will the bang
affect your hearing .The powder that is
released generally does not constitute a
health hazard. The 001FSRS warning lamp
lights up. Occupant safety

in direction, the child may not be held
securely. The child could thus be seriously or
even fatally injured. For this reason, when
fitting a child restraint system, observe the
manufacturer's installation instructions and
the correct use of the child restraint system.
Child restraint systems should preferably be
fitted on the rear seats .The child is generally
better protected there.
The entire base of the child restraint system
must always rest on the seat cushion.
Therefore, never place objects, e.g. a cushion,
under the child restraint system.
Only use child restraint systems with the
original cover designed for them. Only replace
damaged covers with genuine covers.
We recommend that you use the child
restraint systems which have been
recommended for Mercedes-Benz. G
WARNING
Infants and small children should never share
a seat belt with another occupant. In the event
of an accident, they could be crushed
between the occupant and seat belt.
Ac hild's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not face or neck.Ab ooster seat
may be necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) until
they reach a height where a lap-shoulder belt
fits properly without a booster.
When the child restraint is not in use, remove
it from the vehicle or secure it with the seat
belt to prevent the child restraint from
becoming a projectile in the event of an
accident. G
WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. Achild's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts. G
WARNING
Do not carry heavy or hard objects in the
passenger compartment or cargo
compartmentu nless they are firmly secured
in place.
Unsecured or improperly positioned cargo

Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
(Y page 66)
R BAS (Brake AssistSystem) (Y page 67)
R BAS PLUS ( BrakeAssist System Plus)
(Y page 67)
R COLLISION PREVENTION ASSIST
(Y page 68)
R ESP ®
(Electronic StabilityProgram)
(Y page 71)
R EBD ( Electronic Brake force Distribution)
(Y page 73)
R ADAPTIVE BRAKE (Y page 73)
R PRE-SAFE ®
Brake (Y page 73)
R STEER CONTROL (Y page 75)Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road and weather
conditions and maintain asafe distance from
the vehicle in front. Drive carefully.
i The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special attention to the note
son tires,
recommended minimu mtire tread depths,
etc. (Y page 400).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible. ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Importan tsafety notes"
sectio n(Ypage 66). G
WARNING
If ABSi s faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 322) and
display messages which may be shown in the
instrument cluster (Y page 287).
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
ABS works from a speed of about 5 mph
(8 km/h) upwards, regardless of road-surface
conditions. ABS works on slippery surfaces,
even if you only brake gently.
The yellow 0019ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running. 66
Driving safety systemsSafety

or more wheels are braked to stabilize the
vehicle. 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.
4ETS (Electronic Traction System) 4ETS traction control is part of ESP
®
.
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull away and accelerate on slippery surfaces,
for example if the road surface is slippery on
one side. In addition, more drive torque is
transferred to the wheel or wheels with
traction.
Traction control remains active, even if you
deactivate ESP ®
.
In appropriate driving situations, activate the
off-road program:
X Vehicles without the ON&OFFROAD
package (Y page 252)
X Vehicles with the ON&OFFROAD package
(Y page 252)
Off-road 4ETS (Electronic Traction
System) A4
ETS syste mspecifically suited to off-road
terrain is activated automatically once the off-
road program is activated on:
R Vehicles without the ON&OFFROAD
package (Y page 252)

(Y page 252)
Important safety notes G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle .Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop. !
Only operate the vehicle for a maximum
of ten seconds on a brake test
dynamometer. Switch off the ignition.
Application of the brakes by ESP ®
may
otherwise destroy the brake system.
! A function or performance test should
only be carried out on atwo-axle
dynamometer. Before you operate the
vehicle on such a dynamometer, please
consult a qualified workshop .You could
otherwise damage the drive train or the
brake system.
ESP ®
is deactivated if the 0017warning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the 000F warning lamp and the 0017
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 325) and display messages which
may be shown in the instrument cluster
(Y page 287).
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
Characteristics of ESP ® General information
ESP
®
is activated automatically when the
engine is started.
If ESP ®
intervenes, the 000FESP®
warning
lamp flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any
circumstances.
X Only depress the accelerator pedal as far
as necessary when pulling away.
X Adapt your driving style to suit the
prevailing road and weather conditions. Driving safety systems

Active Parking Assist, the 0003symbol is
displayed when Pis engaged or you are
driving faster than 22 mph (35 km/h).
Following damage to the fron tend of the
vehicle, have the configuratio nand operation
of the rada rsensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the fron tofthe vehicle. STEER CONTROL
i Observe the "Important safety notes"
section (Y page 66).
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering
wheel in the direction required for vehicle
stabilization. This steering assistance is provided in
particular if:
R
both right wheels or both left wheels are on
a wet or slippery road surface when you
brake
R the vehicle starts to skid
If ESP ®
is malfunctioning, you will not receive
steering support from STEER CONTROL.
Power steering will, however, continue to
function. Theft deterrent locking system
