systems for infants and children, see
"Children in the vehicle" (Y
page 55).SRS (Supplemental Restraint System)
Introduction SRS consists of:
R
The 6 SRS warning lamp
R Air bags
R The air bag control unit with crash sensors
R Emergency Tensioning Device (ETD) for
seat belts
R Seat belt force limiter
SRS reduces the risk of vehicle occupants
coming into contact with parts of the
vehicle's interior in the event of an accident.
It can also reduce the forces to which vehicle
occupants are subjected during an accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, child restraint
system components may be triggered
unintentionally or might not be triggered at all
in the event of an accident with a high rate of
vehicle deceleration. There is an increased
risk of injury, possibly even fatal.
Have SRS checked and repaired immediately
at a qualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started.
The SRS components are in operational
readiness when the 6SRS warning lamp
goes out while the engine is running. There is a malfunction if:
R
the 6 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 6SRS
warning lamp does not go out after a few
seconds
R the engine is running and the 6SRS
warning lamp lights up again
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags G
WARNING
R Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Benz Center.
R Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment. Check your national disposal
guidelines. In California, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R Air bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETD
that has deployed must be replaced.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts, as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
R Do not make any modifications to the SRS
wiring or components.
R Do not modify or remove any components
or parts of the SRS. Occupant safety

system manufacturer's installation
instructions.
G
WARNING
Child restraint systems or their securing
systems which have been damaged or
subjected to a load in an accident can no
longer protect as intended. The child cannot
then be restrained in the event of an accident,
heavy braking or sudden changes of direction.
There is an increased risk of injury, possibly
even fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the
securing systems on the child restraint
system checked at a qualified specialist
workshop, before you install a child restraint
system again. 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.
A child'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 the face or neck. A booster
seat may be necessary to achieve proper seat
belt positioning for children over 41 lbs
(18 kg) until they reach a height where a lap/
shoulder belt fits properly without a booster
seat.
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
If children are left unsupervised in the vehicle,
they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shift the automatic transmission out of
parking position P.
R shift the manual transmission into neutral.
R starting the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children. G
WARNING
If persons, particularly children are subjected
to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle. G
WARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot.
Children may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before
securing the child in it. Never leave children
unattended in the vehicle. Child restraint systems

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 59)
R BAS ( Brake Assist System) (Y page 60)
R BAS PLUS ( BrakeAssist System PLUS)
(Y page 60)
R ESP ®
(Electronic StabilityProgram)
(Y page 61)
R EBD ( electronic brake force distribution)
(Y page 65)
R ADAPTIVE BRAK E(Ypage 65)
R PRE-SAFE ®
Brake (Y page 65) 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 a safe 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 notes on tires,
recommended minimum tire tread depths,
etc. (Y
page 306).
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)
General information 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.
The yellow
!ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running.
Important safety notes i
Observe the "Important safety notes"
section (Y page 59). G
WARNING
If ABS is 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 242) and
display messages which may be shown in the
instrument cluster (Y page 211).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface Driving safety systems
59Safety Z

ETS traction control is part of ESP
®
.
ETS 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.
ETS remains active when you deactivate
ESP ®
.
i AMG vehicles: your vehicle may be
equipped with 20-inch tires on the rear
axle. If replaced with a 19-inch tire, ETS
may intervene noticeably sooner for the
first few kilometers. After approximately
10 km ETS will function as usual again.
Information on the dimensions and types of
wheels and tires for your vehicle can be
found in the "Wheel/tire combinations"
section ( Ypage 333).
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.
! When testing the electric parking brake
on a braking dynamometer, switch off the
ignition. Application of the brakes by
ESP ®
may otherwise destroy the brake
system.
When towing the vehicle with the rear axle
raised, observe the notes on
ESP ®
(Y page 302).
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the ÷ warning lamp and the å
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction. Observe the information on warning lamps
(Y
page 244) and display messages which
may be shown in the instrument cluster
(Y page 211).
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
Characteristics of ESP ® General information
If the
÷ ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.
If ESP ®
intervenes, the ÷ESP®
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.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts
automatically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. Example:if ESP®
was
deactivated before the engine was switched
off, ESP ®
remains deactivated when the
engine is switched on again.

Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs carry a high voltage. You can get
an electric shock if you remove the cover of
the Xenon bulb and touch the electrical
contacts. There is a risk of fatal injury.
Never touch the parts or the electrical
contacts of the Xenon bulb. Always have work
on the Xenon bulbs carried out at a qualified
specialist workshop.
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs G
WARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
Do not use a bulb that has been dropped or if
its glass tube has been scratched.
The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare 114
