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 understanding
how a vehicle’s systems performed in certain
crash or near crash-like situations, such as dur- ing air bag deployment or when hitting a road
obstacle. The EDR is designed to record 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 oper-
ating
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 understand-
ing of the circumstances in which crashes and
injuries occur. NOTE: EDR data is recorded by
your vehicle only if a non-trivial crash situation
occurs; no data is recorded by the EDR under
normal driving conditions and no personal data
(e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law
enforcement, can combine the EDR
data w
ith
the type of personal identification data routinely
acquired during a crash investigation.
To read data recorded by an EDR, special equip- ment is required, and access to the vehicle or
the EDR is needed. In addition to the vehicle
manufacturer, other parties that have the spe-
cial 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 mat- ters as a tool in accident reconstruction, acci-
dent 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 representation
include responses to subpoenas by law enforce- ment; by federal, state or local government; in
connection with or arising out of litigation involv-
ing MBUSA or its subsidiaries and affiliates; or,
as required by law.
Warni
ng: The EDR is a component of the Sup-
plemental Restraint System ("SRS") Module.
Tampering with, altering, modifying or removing the EDR component may result in a malfunction
of the SRS 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 relating to EDRs.

Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of vehi-
cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces
to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing systems
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all
vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 37)
Rhave adjusted their seat and head restraint
properly (Ypage 72).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Ypage 72).
You also have to make sure that an air bag can
inflate properly if deployed (
Ypage 40).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags

Safety
Method of operation
During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluation of this data, the
restraint system control unit triggers the Emer-
gency Tensioning Devices during a frontal or
rear collision.
An Emergency Tensioning Device can only be
triggered, if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational; see "Restraint system warning
lamp" (
Ypage 35)
Rthe belt tongue is engaged in the buckle on
the respective front-passenger seat
The Emergency Tensioning Devices in the rear
compartment are triggered independently of the
lock status of the seat belts.
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independ-
ently of each other in certain frontal collision
situations:
RDriver's air bag
RFront-passenger front air bag
The front-passenger front air bag is activated or
deactivated depending on the person on the
front-passenger seat. The front-passenger front
air bag can only deploy in an accident if the
PASSENGER AIR BAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR
BAG OFF indicator lamp (
Ypage 35).
Your vehicle has a two-stage driver's air bag.
During the first deployment stage the driver's air
bag fills with sufficient propellant gas to reduce
the risk of injuries. The front air bag is fully
deployed with the maximum amount of propel-
lant gas if a second deployment threshold is
reached within a few milliseconds.
The activation threshold of the Emergency Ten-
sioning Devices and the air bag are determined
by evaluating the rate of vehicle deceleration or
acceleration which occurs at various points in
the vehicle. This process i
s pre-emptive in
nature. Deployment should take place in good
time at the start of the collision. The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
Rthe distribution of forces during the collision
Rthe collision angle
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 deci-
sive role in the deployment of an air bag. Nor do
they provide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if
only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result.
If the restraint system control unit detects a side impact or if the vehicle rolls over, the applicable
components of the restraint system are activa-
ted independently of each other depending on
the apparent type of accident.
RSide impact air bag and pelvis air bag on the
side of impact, independently of the Emer-
gency Tensioning Device and the use of the
seat belt
The side impact air bag on the front-
passenger side deploys under the following
conditions:
-BabySmart™ 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
REmergency Tensioning Devices, if the system determines that deployment can offer addi-
tional protection in this situation
RWindow curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection to that provided by the seat
belt

Safety
GWARNING
If the ABS malfunctions, other driving systems such as the BAS or the ESP
®are also switched
off. Observe indicator and warning lamps that may come on as well as messages in the mul-
tifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance.
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
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.
Provided that the differential locks are not
active, ABS works from a speed of approx-
imately 5 mph (8 km/h) upwards, regardless of
road-surface conditions. ABS works on slippery
surfaces, even if you only brake gently.
The yellow !ABS warning lamp in the instru-
ment cluster lights up when the ignition is
switched on. It goes out when the engine is run-
ning.
Braking
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
XIf ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo make a full brake application: depress
the brake pedal with full force.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a
reminder to take extra care while driving.
Off-road ABS
An ESP®system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated.
At speeds below 37 mph (60 km/h), the front
wheels lock cyclically during braking. The dig-
ging-in effect achieved in the process reduces
the stopping distance on off-road terrain. This
limits steering capability.
BAS (Brake Assist System)
i
Observe the "Important safety notes" sec-
tion (Ypage 55).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
XKeep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
Adaptive brake lights
If you brake sharply from a speed of more than
30 mph (50 km/h) or if braking is assisted by
BAS, the brake lamps flash rapidly. In this way,
traffic traveling behind you is warned in an even
more noticeable manner.
If you brake sharply from a speed of more than
45 mph (70 km/h) to a standstill, the hazard
warning lamps are activated automatically. If
the brakes are applied again, the brake lamps
light up continuously. The hazard warning lamps
are deactivated automatically if you drive faster
than 6 mph (10 km/h). You can also switch off
the hazard warning lamps using the hazard
warning button (
Ypage 89).

Ran air bag is deployed or
Rthe Emergency Tensioning Devices are trig-
gered, or
Rthe vehicle decelerates rapidly from a speed
of above 45 mph (70 km/h) and comes to a
standstill
The hazard warning lamps switch on automati-
cally if an air bag or the Emergency Tensioning
Devices are triggered and the SmartKey is in
position 1in the ignition lock.
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
6 mph (10 km/h) again after a full brake appli-
cation.
iThe hazard warning lamps still operate if the
ignition is switched off.
Headlamps and indicator lamps fog-
ged up on the inside
The headlamps and the indicator lamps in the
exterior mirrors may fog up on the inside if there
is high atmospheric humidity.
XDrive with the headlamps switched on.
The level of moisture diminishes, depending
on the length of the journey and the weather
conditions (humidity and temperature).
If the level of moisture does not diminish:

Overview of climate control systems
Important safety notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up. This could prevent you from observing the
traffic conditions, thereby causing an accident.
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Dual-zone automatic climate control is only
operational when the engine is running. Opti-
mum operation is only achieved if you drive with
the side windows and sliding sunroof closed.
The climatic comfort deteriorates whilst the slid-
ing sunroof is open. The automatic climate con-
trol cannot maintain the set temperature with
the sliding sunroof open. You have to adjust the
climate control manually.
iThe residual heat function can only be acti-
vated or deactivated with the ignition
switched off (
Ypage 108).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 68). This will speed
up the cooling process and the desired vehi-
cle interior temperature will be reached more
quickly.
iThe integrated filter can filter out most par-
ticles of dust, and completely filters out pol-
len. A clogged filter reduces the amount of air
supplied to the vehicle interior. For this rea-
son, you should always observe the interval
for replacing the filter, which is specified in
the Maintenance Booklet. As it depends on
environmental conditions, e.g. heavy air pol- lution, the interval may be shorter than stated
in the Maintenance Booklet.
