NOTEEnvironmental
dama gedue tooperating conditions and
personal driving style The pollutant emission of
theve hicle is
directly related tothewa yyo u operate the
ve hicle.
Operate your vehicle in an environmentally
re sponsible manner tohelp pr otect the envi‐
ro nment. Please obser vethefo llowing rec‐
ommendations on ope rating conditions and
pe rsonal driving style.
Operating conditions: #
Make sure that the tyre pressure is cor‐
re ct. #
Do not car ryany unnecessary weight
(e.g. roof luggage rack s once you no
lon ger need them). #
Adhere tothe service inter vals.
A regularly serviced vehicle will contri b‐
ute toenvironmen tal pr otection. #
Alw ays ha vemaintenance workcar ried
out at a qualified specialist workshop.
Pe rsonal driving style: #
Do not depress the accelera tor pedal
when starting the engine. #
Do not warm upthe engine while the
ve hicle is stationar y. #
Drive carefully and maintain a suitable
di st ance from theve hicle in front. #
Avoid frequent, sudden acceleration
and braking. #
Change gear in good time and use each
ge ar on lyup toÔ of its maximum
engine speed. #
Switch off the engine in stationary traf‐
fi c, e.g. byusing the ECO start/ stop
function. #
Drive fuel-ef ficiently. Obser vethe ECO

General ly,th e use of these data is temp orar y;
th ey will not be stored be yond the period of
operation and will only be processed within the
ve hicle itself. Control units of ten contain da ta
memories forve hicle keys,fo rex ample. Their
use permits thete mp orary or permanent docu‐
mentation of tech nical information about the
ve hicle's operating state, component loads,
main tenance requ irements and tech nical events
or faults.
Depending on theve hicle equipment, thefo llow‐
ing data are stored:
R operating status of sy stem components,
such as fill le vels, tyre pressure or battery
st atus
R malfunctions or faults in impor tant sy stem
components, such as lights or brakes
R system reactions in special driving situations,
such as airbag deployment or the inter ven‐
tion of stability control sy stems R
information on events leading tovehicle
damage
In cer tain cases, it may be requiredtostore data
th at wo uld ha veotherwise been used only tem‐
poraril y.This may be the case if theve hicle has
de tected a malfunction, forex ample.
If yo u use services, such as repair services and
maintenance work,st ored operational data as
we ll as theve hicle identification number can be
re ad out and used. They can be read out by
service network emplo yees, such as workshops
and manufacturers or third parties, such as
breakdown services. The same is true in the
case of warranty claims and quality assurance
measures.
In general, there adout is per form ed via the
legally prescribed port forth e diagnostics con‐
nection in theve hicle. The operational data that
are read out document tech nical states of the
ve hicle or of individual components and assist in
th e diagnosis of malfunctions, compliance with
wa rranty obligations and quality impr ovement.
To that end, these data, in particular information
about component loads, tech nical events, mal‐ functions and
other faults may be transmitted
along with theve hicle identification number to
th e manufacturer. Furthermore, the manufac‐
turer is subject toproduct liability. Forth is rea‐
son the manufacturer also uses operational data
from theve hicle, forex ample, forre calls. These
da ta can also be used toexamine the cus tom‐
er's warranty and guarantee claims.
Fa ult memories in theve hicle can be reset by a
service outlet or at your requ est as part of repair
or maintenance work.
Con venience and inf otainment functions
Yo u can store con venience settings and individ‐
ual settings in theve hicle and change or reset
th em at any time.
Depending on theve hicle equipment, this
includes thefo llowing settings, forex ample:
R seat and steering wheel positions
R suspension and climate control settings
R individual settings, such as interior lighting
Depending on the selected equipment, you can
import data into vehicle inf otainment functions
