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 https:// 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
It is read by employees of the service network (including manufacturers) using special diag-
nostic testers. More detailed information is
obtained from it, 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
connection with other information (if neces-
sary, under consultation with an authorised
expert), could be traced to a person.
Examples include:
R accident reports
R damage to the vehicle
R witness statements
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case of an emergency. Introduction

It is only possible to shift the transmission
from position
Pto the desired position if you
depress the brake pedal. Only then can the
parking lock be deactivated.
If you do not depress the brake pedal, the
DIRECT SELECT lever can still be moved but
the parking lock remains engaged.
At transmission fluid temperatures below
Ò20 †, you can only shift out of position Pinto
another transmission position when the
engine is running.
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Information on automatically releasing the
electrical parking brake (Y page 182).
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
brake and prevent the vehicle from rolling
backwards.
The red !indicator lamp in the instru-
ment cluster remains lit.
X Depress the accelerator pedal.
X As soon as the vehicle/trailer combination
is held by the driving force of the engine,
release lever :.
the electric parking brake is released. The red
!indicator lamp in the instru-
ment cluster goes out.
For further information on the electric parking
brake, see (Y page 182).
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 short time, hill start assist will no lon-
ger brake your vehicle and it could 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 ®
is malfunctioning
Further information on holding the vehicle
stationary on uphill gradients (Y page 173). ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stop-
ped under certain conditions.
When pulling away again, the engine starts
automatically. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle. Driving
