traffic rules and regulations
R laws and safety standards pertaining to
motor vehicles Implied 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 are not covered either by
Mercedes-Benz implied warranty or by the
New or Used-Vehicle Warranty. QR code for rescue card
The QR code is 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, in a compact form, the
most important information about your vehi-
cle, e.g. the routing of the electric cables.
You can find more information under http:// portal.aftersales.i.daimler.com/public/
content/asportal/en/communication/
informationen_fuer/QRCode.html. Data stored in the vehicle
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings. These include, for example:
R operating conditions of system compo-
nents, e.g. fluid levels
R the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
R malfunctions and defects in important sys-
tem components, e.g. lights, brakes
R vehicle reactions and operating conditions
in special driving situations, e.g. airbag
deployment, intervention of stability con-
trol systems
R ambient conditions, e.g. outside tempera-
ture
This data is of an exclusively technical nature and can be used to:
R assist in detecting and rectifying faults and
defects
R analyse vehicle functions, e.g. after an acci-
dent
R optimise vehicle functions
The data cannot be used to trace the vehicle's movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data mem- ory and fault data memory.
Services include, for example:
R repair services
R service processes
R warranty events
R quality assurance
The vehicle is read out by employees of the
service network (including the manufacturer)
using special diagnostic testers. You can
obtain more information there, if required.
After a fault has been rectified, the informa-
tion is deleted from the fault memory or is
continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in

Switching the windscreen wipers on/

! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratch the glass if wiping takes place when the windscreen is dry.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
always operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto- matic car wash. Combination switch

depress the brake pedal. Only then can the
parking lock be deactivated.
All vehicles (except Mercedes-AMG vehi-
cles): if you do not depress the brake pedal,
the DIRECT SELECT lever can still be moved
but the parking lock remains engaged.
Mercedes-AMG vehicles: if you do not
depress the brake pedal, the selector lever
can still be moved but the parking lock
remains engaged.
Vehicles with automatic transmission: at
transmission fluid temperatures below
Ò20 †, you can only shift out of position Pinto
another transmission position when the
engine is running.
i Vehicles with automatic transmis-
sion: upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Vehicles with automatic transmission:
information on automatically releasing the
electric parking brake (Y page 185).
Pulling away with a trailer To ensure that you do not roll backwards
when pulling away on an uphill slope, apply
the electric parking brake.
X Press and hold handle :.
The electric parking brake continues to

For further information on the electric parking
brake, see (Y page 185).
Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot from the brake pedal to the accelerator pedal and depress it before the vehicle begins to
roll. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may roll away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
R you are pulling away on a level road or a
downhill gradient
R on vehicles with automatic transmission,
the transmission is in position N
R the electric parking brake is applied
R ESP ®
