Limited Warranty
!
Follow the instructions in this manual
about the proper operation of your vehicle
as well as about possible vehicle damage.
Damage to your vehicle that arises from
culpable contraventions against these
instructions is not covered either by the
Mercedes-Benz Limited Warranty or by the New or Used-Vehicle Warranty.
QR codes for the rescue card
The QR codes are secured in the fuel filler flap
and on the opposite side on the B-pillar. In the event of an accident, rescue services can use
the QR code to quickly find the appropriate
rescue card for your vehicle. The current res- cue card contains the most important infor-
mation about your vehicle in a compact form, e.g. the routing of the electric cables.
You can find more information under https://
portal.aftersales.i.daimler.com/public/

Data stored in the vehicle
Data recording
This vehicle is capable of recording diagnostic information relating to vehicle operation, mal-
functions, and user settings. This may include information about the performance or status
of various systems, including but not limited
to, engine, throttle, steering or brake sys-
tems, that is stored and can be read out with
suitable devices, particularly when the vehi-
cle is serviced. The data obtained is used to
properly diagnose and service your vehicle or to further optimize and develop vehicle func-
tions.
COMAND/mbrace
If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle’s
operation, the use of the vehicle in certain
situations, and the location of the vehicle maybe compiled through COMAND or the mbrace system.
For additional information please refer to the
COMAND User Manual and/or the mbrace
Terms and Conditions.
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 under-
standing how a vehicle’s systems performed
in certain crash or near crash-like situations,
such as during 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: R how various systems in your vehicle are
operating
R whether or not the driver and passenger
seat belts are fastened
R how far (if at all) the driver is depressing the
accelerator and/or brake pedal and
R how 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 non-trivial
crash situation occurs; no data is recorded by the EDR under normal driving conditions andno personal data (e.g., name, gender, age,
and crash 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.

!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.

Battery (vehicle)
Important safety notes
Special tools and expert knowledge are
required when working on the battery, e.g.
removal and installation. You should there-
fore have all work involving the battery car-
ried out at a qualified specialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP ®
(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
R when braking
R in the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car- ried out at a qualified specialist workshop.
For further information about ABS and ESP ®
,
see ( Ypage 61) and ( Ypage 64).

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of apositive terminal and a ground point, in the engine compartment.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the
battery. Keep children away from batteries. Wash away battery acid immediately with plenty of
clean water and seek medical attention.
GWARNING
During charging and jump-starting, explosive gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ven-
tilation while charging and jump-starting. Do not lean over a battery.
GWARNING
During the charging process, a battery produces hydrogen gas. If a short circuit occurs or sparks
are created, the hydrogen gas can ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a connected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on a battery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting a battery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jumper cables.
R Never connect or disconnect the battery terminals while the engine is running.
GWARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the
discharged battery has frozen. In this case you may neither jump-start the vehicle nor charge
the battery. Let the battery thaw first. The service life of a thawed-out battery may be shorter.
The starting characteristics can be impaired, particularly at low temperatures. Have the
thawed-out battery checked at a qualified specialist workshop.
