Data stored in the vehicle
Data recording
This vehicle is capable of recording diag-
nostic information relating to vehicle oper-
ation, malfunctions, and user settings. This
may include information about the perform-
ance or status of various systems, including
but not limited to, engine, throttle, steering
or brake systems, that is stored and can be
read out with suitable devices, particularly
when the vehicle is serviced. The data
obtained is used to properly diagnose and
service your vehicle or to further optimize
and develop vehicle functions.
Event data recorders
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is
to record data that will assist in understand-
ing how a vehicle’s systems performed in cer-
tain crash or near crash-like situations, such
as during air bag deployment or when hitting
a road obstacle. The EDR is designed to record
20>> Introduction.

data related to vehicle dynamics and safety
systems for a short period of time, typically
30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
Rhow various systems in your vehicle are
operating
Rwhether or not the driver and passenger
seat belts are fastened
Rhow far (if at all) the driver is depressing
the accelerator and/or brake pedal and
Rhow fast the vehicle is traveling
This data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur. NOTE: EDR data is
recorded by your vehicle only if a nontrivial
crash situation occurs. No data is recorded by
the EDR under normal driving conditions. No
personal data (e.g., name, gender, age, and
accident location) are recorded. However,
other parties, such as law enforcement, can
combine the EDR data with the type of per-
sonal identification data routinely acquired
during a crash investigation. EDR data may be
used in civil and criminal matters as a tool in
accident reconstruction, accident claims,
and vehicle safety.
To read data recorded by an EDR, special
equipment is required, and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer, other parties that
have the special equipment, such as law
enforcement, can read the information by
accessing the vehicle or the EDR.
EDR data may be used in civil and criminal
matters as a tool in accident reconstruction,
accident claims, and vehicle safety. Since
the Crash Data Retrieval CDR tool that is used
to extract data from the EDR is commercially
available, Mercedes-Benz USA, LLC
("MBUSA") expressly disclaims any and all
liability arising from the extraction of this
information by unauthorized Mercedes-Benz
personnel.
MBUSA will not share EDR data with others
without the consent of the vehicle owners or,
if the vehicle is leased, without the consent
of the lessee. Exceptions to this representa- tion include responses to subpoenas by law
enforcement; by federal, state or local gov-
ernment; in connection with or arising out of
litigation involving MBUSA or its subsidi a-
ries and affiliates; or, as required by law. Warning: the EDR is a component of the
Restraint System Module. Tampering with,
altering, modifying or removing the EDR com-
ponent may result in a malfunction of the
Restraint System Module and other systems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-
empted. This means that in the event of such
conflict, the federal regulation governs. As
of February 2013, 13 states have enacted laws
related to EDRs.

Rthe deformation characteristics of the
vehicle
Rthe characteristics of the object with
which the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a
decisive role in the deployment of an air bag.
Nor do they provide an indication of air bag
deployment.
The vehicle can be deformed considerably,
without an air bag being deployed. This is the
case if only parts which are relatively easily deformed are affected and the rate of decel-
eration is not high. Conversely, air bags may
be deployed even though the vehicle suffers
only minor deformation. This is the case if,
for example, very rigid vehicle parts such as longitudinal body members are hit, and suf-
ficient deceleration occurs as a result.
If the control unit of the restraint system
detects a side impact or a vehicle rollover,
the relevant components of the restraint sys-
tem are activated separately depending on
the anticipated type of accident.
RThorax/pelvis air bag on the side of
impact, independently of the Emergency
Tensioning Device and the use of the seat
belt
The thorax/pelvis air bag on the front-
passenger side deploys under the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the belt tongue is engaged in the belt
buckle of the front-passenger seat
RWindow curtain air bag on the side of
impact, independently of the use of the seat
belt and independently of whether the
front-passenger seat is occupied
RWindow curtain air bags on the driver's andfront-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer
additional protection to that provided by
the seat belt
REmergency Tensioning Devices, if the sys-
tem determines that deployment can offer
additional protection in this situation
iNot all air bags are deployed in an acci-
dent. The differ ent air bag systems work
independently of each other. How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or
acceleration and the apparent type of acci-
dent:
RFrontal collision
RSide impact
RRollover
Children in the vehicle
Important safety notes
If a child younger than 12 years and under 5 ft
(1.50 m) in height is traveling in the vehicle:
Ralways secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child
Rbe sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
Rbe sure to observe the instructions and
safety notes in "Occupant classification
system (OCS)" (
Ypage 36)
GWARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of
park position Por shift manual trans-
mission into neutral.
Rstart the engine.
In addition, they may operate vehicle
equipment and become trapped. 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 unsupervised in the
vehicle.

Driving safety systems
Overview of driving safety systems
In this section, you will find information
about the following driving safety systems:
RABS (Anti-lock BrakingSystem)
(Ypage 47)
RDistance warning function (Ypage 48)
Resp®(Electronic StabilityProgram)
(Ypage 49)
REBD (Electronic Brake forceDistribution)
(Ypage 50)
Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety sys-
tems 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 prevail-
ing road, weather and traffic conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
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. (
Ypage 177).
In wintry driving conditions, always use win-
ter 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. For safety reasons, smart recommends that you
only use snow chains that have been specially
approved for your vehicle by smart, or fine-
link snow chains that are of a corresponding
standard of quality. For more information,
please contact a qualified specialist work-
shop.
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 vehi-
cle when braking.
The 0025 (Canada only) or 00DF(USA only) 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
iObserve the "Important safety notes" sec-
tion for driving safety systems (Ypage 47).
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 132) and
display messages which may be shown in the
instrument cluster (
Ypage 121).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety sys-
tems are deactivated. There is an increased
danger of skidding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
abs works from a speed of about 4 mph (6 km/h),
regardless of road-surface conditions. ABS
works on slippery surfaces, even if you only
brake gently.

Braking
XIf ABS intervenes:continue to depress the
brake pedal vigorously until the braking
situation is over.
XTo make a full brake application: depress
the brake pedal with full force.
If abs intervenes when braking, you will feel
a pulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving.
Forward collision warning
General information
The distance warning function can help you to
minimize the risk of a collision with a vehi-
cle ahead or reduce the effects of such an
accident. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically.
Starting the engine also switches on the dis-
tance warning function.
Important safety notes
GWARNING
The distance warning function does not
react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
Thus, the distance warning function cannot
provide a warning in all critical situa-
tions. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
GWARNING
The distance warning function cannot
always clearly identify objects and com-
plex traffic situations.
In such cases, the distance warning func-
tion may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay careful attention to the traffic
situation and do not rely solely on the dis-
tance warning function.
Observe the "Important safety notes" section for driving safety systems (
Ypage 47).
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors.
Rsnow or heavy rain
Rinterference by other radar sources
Rthe possibility of strong radar reflec-
tions, for example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different
line
Rnew vehicles or after a service on the dis-
tance warning system
Please observe the information in the sec-
tion on running-in the vehicle
(
Ypage 86).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.

XTo switch off:press button0044.
Indicator lamp 0043lights up.
XTo switch on: press button0044.
Indicator lamp 0043goes out.
Starting at a speed of around 4 mph (7 km/h),
the distance warning function warns you if
you rapidly approach a vehicle in front. An
intermittent warning tone will then sound
and the 00BAdistance warning lamp will
light up in the instrument cluster.
XBrake immediately in order to increase the distance from the vehicle in front.
or
XTake evasive action, provided it is safe to
do so.
Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause the system to display a
warning.
With the help of the radar sensor system, the
distance warning function can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
Up to a speed of around 45 mph (70 km/h), the
distance warning function can also react to
stationary obstacles, such as stopped or
parked vehicles.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-
tion (Ypage 47).
esp
®monitors driving stability and traction,
i.e. power transmission between the tires and the road surface.
If esp
®detects that the vehicle is deviating
from the direction desired by the driver, one
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.
ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion (Ypage 47).
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 with traction.
Important safety notes
GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, fur-
ther driving safety systems are deactiva-
ted. This increases the risk of skidding and
an accident.
Drive on carefully. Have ESP
®checked at a
qualified specialist workshop.
!If you test the parking brake using a brake
dynamometer, switch the ignition off.
Application of the brakes by ESP
®may oth-
erwise destroy the brake system.
When towing the vehicle with the rear axle
raised, observe the notes on esp
®
(Ypage 171).
If the 00E5esp®warning lamp lights up per-
manently, esp®or hill start assist are
unavailable due to a malfunction.
Observe the information on warning lamps
(
Ypage 134) and display messages which may
be shown in the instrument cluster
(
Ypage 121).
iOnly use wheels with the recommended
tire sizes. Only then will esp®function
properly.
Characteristics of ESP®
