If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle's
operation, the use of the vehicle in certain sit-
uations, and the location of the vehicle may be
compiled through COMAND or the mbrace sys-
tem.
For additional information please refer to the
COMAND User Manual or the Digital Operator's
Manual and/or the mbrace Terms and Condi-
tions. Event data recorders
This vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with an event data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deploy- ment or hitting a road obstacle, data that will
assist in understanding how a vehicle's systems
performed. The EDR is designed to record data
relating 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:
R How various systems in your vehicle were
operating
R Whether or not the driver and passenger
safety belts were buckled/fastened
R How far (if at all) the driver was depressing the
accelerator and/or brake pedal and
R How fast the vehicle was traveling
These data can help provide a better under-
standing of the circumstances in which crashes
and injuries occur. NOTE:EDR data are recor-
ded by your vehicle only if a non-trivial crash
situation occurs; no data are 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 could combine the
EDR data with the type of personally identifying
data routinely acquired during a crash investi-
gation.
Access to the vehicle and/or the EDR is needed to read data that is recorded by an EDR, and
special equipment is required. In addition to the
vehicle manufacturer, other parties that have
the special equipment, such as law enforce-
ment, 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.
Warning: The EDR is a component of the
Restraint System Module. Tampering with, alter-
ing, modifying or removing the EDR component
may result in a malfunction of the Restraint Sys- tem Module and other systems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-empted. 34

Important safety notes
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 if it 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
Use bulbs only in closed lamps that have been
designed for this purpose. Only install spare
bulbs of the same type and the specified volt-
age.
Marks on the glass tube reduce the service life
of the bulbs. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Replace only the bulbs listed (Y page 115).
Have the bulbs that you cannot replace yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop.
Headlamps and lights 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. Overview of bulb replacement - bulb

Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications. Always have
work on the engine carried out at a qualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Benz Center for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop.
The engine settings must not be changed under any circumstances. Furthermore, all specific
service work must be carried out at regular
intervals and in accordance with the Mercedes-
Benz service requirements. You can obtain current information concerning
the servicing of your vehicle at any time from a
qualified specialist workshop. This could be an
overview of the maintenance work or any addi-
tional maintenance work, for example. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you

Important safety notes G
WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving on an unpaved road or off-road,
check the vehicle underside regularly. In par-
ticular, remove trapped plant parts or other
flammable material. Contact a qualified spe-
cialist workshop immediately if damage is
detected. G
WARNING
If the vehicle level is high, the vehicle center of gravity is raised. This could cause the vehicleto tip over more easily on uphill or downhill
gradients. There is a risk of an accident.
Select the lowest possible vehicle level.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
curb or an unpaved road
R you drive too fast over an obstacle, e.g. a
curb, a speed bump or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tires could be
damaged without the damage being visible. Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the loads they are designed
to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop.
When driving off-road, substances such as sand,
mud and water or water mixed with oil may get
into the brakes. This could result in a reduced
braking effect or in total brake failure and also in
increased wear and tear. The braking charac-
teristics change depending on the material
entering the brakes. Clean the brakes after driv-
ing off-road. If you detect a reduced braking
effect or grinding noises, have the brake system checked in a qualified specialist workshop as
soon as possible. Adapt your driving style to the
different braking characteristics.
Driving off-road increases the likelihood of dam- age to the vehicle, which, in turn, can lead to
failure of the mechanical assembly or systems.
Adapt your driving style to suit the terrain con-
ditions. Drive carefully. Have damage to the
vehicle rectified immediately at a qualified spe-
cialist workshop.
Do not shift into transmission position 005Cwhen
driving off-road. You could lose control of the
vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for
your vehicle, drive back down in reverse gear.

Driving over obstacles
!
Obstacles could damage the floor of the
vehicle or components of the chassis. Ask
passengers for guidance when driving over
large obstacles. The passenger should always
keep a safe distance from the vehicle when
doing so in order to avoid injury as a result of unexpected vehicle movements. After driving
off-road or over obstacles, check the vehicle
for possible damage, especially to the under- body and the components of the chassis. Observe the following rules when driving over
tree stumps, large stones and other obstacles:
R Select the Offroaddrive program (vehicles
with Off-road Engineering Package)
(Y page 216).
R Select the Offroaddrive program (vehicles
without Off-road Engineering Package)

Driving with Active Distance Assist
DISTRONIC Pulling away and driving
X If you want to pull away with Active Dis-
tance Assist DISTRONIC: remove your foot
from the brake pedal.
X Briefly pull the cruise control lever towards
you 0085.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to
the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically.
If there is no vehicle in front, Active Distance
Assist DISTRONIC operates in the same way as cruise control.
If Active Distance Assist DISTRONIC detects a
slower-moving vehicle in front, it brakes your
vehicle. In this way, the distance you have selec-
ted is maintained.
If Active Distance Assist DISTRONIC detects a
faster-moving vehicle in front, it increases the
driving speed. However, the vehicle is only
accelerated up to the speed you have stored.
Selecting the drive programActive Distance Assist DISTRONIC supports a
sporty driving style if you have selected the
Sport orSport Plus drive program
(Y page 146). Acceleration behind the vehicle in
front or to the set speed is then noticeably more
dynamic. If you have selected the Comfortdrive
program, the vehicle accelerates more gently.
This setting is recommended in stop-and-start
traffic.
Changing lanes If you change to the overtaking lane, Active Dis-
tance Assist DISTRONIC helps you if:
R you are driving faster than 45 mph (70 km/h)
R you switch on the appropriate turn signal
R Active Distance Assist DISTRONIC does not
currently detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance between your vehicle and the vehicle in front
becomes too small.
i When you change lanes, Active Distance
Assist DISTRONIC monitors the right lane (in
left-side traffic) or the left lane (in right-side
traffic).
Stopping G
WARNING
If you leave the driver's seat when the vehicle is only being braked by Active Distance Assist
DISTRONIC, it could roll away:
R if there is a malfunction in the system or in
the voltage supply
R if Active Distance Assist DISTRONIC is
deactivated using the cruise control lever,
for example by a vehicle occupant or from
outside the vehicle
R if the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R if the battery is disconnected
R if the vehicle is accelerated, e.g. by a vehi-
cle occupant
There is a risk of an accident.
Always deactivate Active Distance Assist
DISTRONIC and secure the vehicle against
rolling away before you leave it.
If Active Distance Assist DISTRONIC detects
that the vehicle in front is stopping, it brakes
your vehicle until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever. 174
