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

DANG ER Risk of fata l injury due topoi‐
sonous exhaust gases
If th eta ilpipe is bloc ked or suf ficient ventila‐

TEReduced battery life due tofre‐
qu ent short-dis tance trips The
12V battery may not be suf ficiently

s on driving with a roof load, trailer or
fully laden vehicle
When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu‐
pied vehicle, theve hicle's driving and steering
ch aracteristics change. Yo
u should bear thefo llowing in mind:
R Do not exceed the permissible roof load and
to wing capacity. Also obser vethete ch nical
da ta inthe printed Owner's Manual.
R Evenly distribute thero of load, and place
heavy objects at the bottom. Also comply
with the no tes on loading theve hicle
(/ page 108).
R Drive attentivel y,and avoid sudden lypulling
aw ay, braking and steering as well as rapid
cornering.
Note s on driving on salt-treated roads
The braking ef fect is limited on salt-trea ted
ro ads.
Therefore, obse rveth efo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
conside rably or result in braking only on one
side
R maintain a much greater safe dis tance tothe
ve hicle in front To
remo vesalt build-up:
R brake occasionally while paying attention to
th e tra ffic conditions
R carefully depress the brake pedal at the end
of the journey and when starting the next
journey
Note s on aquaplaning
Aq uaplaning can take place once a cer tain
amount of water has accumulated on thero ad
sur face.
Obser vethefo llowing no tes during heavy precip‐
itation or in conditions in which aquaplaning may
occur:
R reduce speed
R avoid tyre ruts
R avoid sudden steering mo vements
R brake carefully

Glide mode can be ended bypressing a
st eering wheel gearshift paddle
(/ page 160). Fu
nction of the 4MATIC
4MATIC ensures that all four wheels are driven.
To get her with ESP ®
and 4ETS, 4MATIC impr oves
th e traction of your vehicle whene ver a driven
wheel spins due toinsuf ficient traction.
If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor over‐
ri de the la wsof ph ysics. 4MATIC cannot take
account of road, weather and traf fic conditions.
4MATIC is only an aid. You are responsible espe‐
cially for maintaining a safe dis tance from the
ve hicle in front, forve hicle speed, for braking in
good time and forst ay ing in lane.
% In wint ryroad conditions, the maximum
ef fect of 4MATIC can be achie ved only if you
use winter tyres (M+S tyres), with sn ow
