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 contra-

QR codes for rescue cards
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 codes to quickly find the appropriate
rescue cards for your vehicle. The current res-
cue card contains the most important informa-
tion about your vehicle in a compact form, e.g.
the routing of the electric cables.

Data stored in the vehicle
Data recording
A wide range of electronic components in your
vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
RVehicle's operating state
RIncidents
RMalfunctions In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
Roperating conditions of system components,
e.g. fluid levels
Rthe vehicle's status messages and those of its
individual components, e.g. number of wheel
revolutions/speed, deceleration in move-
ment, lateral acceleration, accelerator pedal
position
Rmalfunctions and defects in important system
components, e.g. lights, brakes
Rvehicle reactions and operating conditions in
special driving situations, e.g. air bag deploy-
ment, intervention of stability control sys-
tems
Rambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to:
Rassist in recognizing and rectifying malfunc-
tions and defects
Ranalyze vehicle functions, e.g. after an acci-
dent
Roptimize vehicle function
The data cannot be used to trace the vehicle's
movements.
When your vehicle is servic ed, te
chnical infor-
mation can be read from the event data memory
and malfunction data memory.
Services include, for example:
Rrepair services
Rservice processes
Rwarranties
Rquality assurance
It is read by employees of the service network
(including manufacturers) using special diag-
nostic devices. More detailed information is
obtained from it, if required.
After a malfunction has been rectified, the infor-
mation is deleted from the malfunction memory
or is continually overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec-
tion with other information (if necessary, under
consultation with an authorized expert), could
be traced to a person.

Windshield wipers
Switching the windshield wipers
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield/rear window can
scratch the glass if wiping takes place when
the windshield/rear window is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield/rear window after the vehicle has
been washed in an automatic car wash, this
may be due to wax or other residue. Clean the
windshield/rear window with washer fluid
after an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratch the windshield.
For this reason, you should always switch off
the windshield wipers in dry weather.
96Windshield wipers
Lights and windshield wipers

Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the airflow
to cool the brakes more quickly.
Wet roads
If driving in heavy rain for a prolonged period of time without braking, there may be a delayed
reaction from the brakes when braking for the
first time. This may also occur after the vehicle
has been washed.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehicle washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.
RBrake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
!If the brake warning lamp lights up in the
instrument cluster and you hear a warning
tone even though the parking brake has been released, the brake fluid level may be too low.
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines. Have the brake system checked immediately.
This work should be carried out at a qualified
specialist workshop.
!A function or performance test should only
be carried out on a 2-axle dynamometer. If
you are planning to have the vehicle tested on
such a dynamometer, contact an authorized
Mercedes-Benz Center to obtain further infor-
mation first. Otherwise, you could damage
the drive train or the brake system.
!As the ESP®system operates automatically,
the engine and the ignition must be switched
off (the SmartKey must be in position 0or 1in
the ignition lock) if the parking brake is tested
on a brake dynamometer (for a maximum of
ten seconds).
Braking applications triggered automatically
by ESP
®may otherwise seriously damage the
brake system.
Mercedes-Benz recommends that you only have
brake pads/linings installed on your vehicle
which have been approved for Mercedes-Benz
vehicles or which correspond to an equivalent
quality standard. Brake pads/linings which have
not been approved for Mercedes-Benz vehicles
or which are not of an equivalent quality could
affect your vehicle's operating safety.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for
your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake
fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If your brake system is subject only to moderate
loads, you should test the functionality of your
brakes at regul ar interva
ls by pressing firmly on
the brake pedal at high speeds. This improves
the grip of the brake pads.
You can find a description of Brake Assist (BAS)
on (
Ypage 56).
