your vehicle is

Help toprotect the environment byoperating
yo ur vehicle in an environmentally responsi‐
ble manner. Please obser vethefo llowing rec‐
ommendations on ope rating conditions and
pe rsonal driving style.
Operating conditions: #
Make sure that the tire pressure is cor‐

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‐

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 to00C3 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

Fu rther information can be obtained at http://

storage Electronic control units
Elect
ronic control units are ins talled in your vehi‐
cle. Some of these are necessary forth e safe
operation of your vehicle, while some assist you
when driving (driver assis tance sy stems). In
addition, your vehicle pr ovides com fort and
enter tainment functions, which are also made
possible byelectronic control units.
Elect ronic control units contain da tamemories
which cantemp orarily or permanently store
te ch nical information about theve hicle's operat‐
ing state, component loads, main tenance
re qu irements and tech nical events or malfunc‐
tions. In
general, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings such as:
R operating status of sy stem components (e.g.
fi ll le vels, battery status, tire pressure)
R status messages concerning theve hicle or
its individual components (e.g. number of
wheel revo lutions/speed, longitudinal accel‐
eration, lateral acceleration, display of fas‐
te ned seat belts)
R malfunctions or faults in impor tant sy stem
components (e.g. lights, brakes)
R information on events leading tovehicle
damage
R system reactions in special driving situations
(e.g. airbag deployment, inter vention of sta‐
bility control sy stems)
R ambient conditions (e.g. temp erature, rain
sensor)
In addition toprov iding the actual control unit
function, this data assists the manufacturer in
de tecting and rectifying malfunctions and opti‐
mizing vehicle functions. The majority of this data is
temp orary and is only processed in the
ve hicle itself. Only a small portion of the data is
st ored in theeve nt or malfunction memor y.
When your vehicle is serviced, tech nical da ta
from theve hicle can be read out byservice net‐
wo rkemplo yees (e.g. workshops, manufactur‐
ers) or third parties (e.g. breakdown services).
Services include repair services, maintenance
processes, warranty claims and quality assur‐
ance measures, forex ample. The read out is per‐
fo rm ed via the legally prescribed port forthe
diagnostics connection in theve hicle. The
re spective service network locations or third
parties collect, process and use the data. They
document tech nical statuses of theve hicle,
assist in finding malfunctions and impr oving
qu ality and are transmit tedto the manufacturer,
if necessar y.Fu rthermore, the manufacturer is
subject toproduct liability. Forth is, the manu‐
fa cturer requirestech nical da tafrom vehicles.
Fa ult memories in theve hicle can be reset by a
service outlet as part of repair or maintenance

General no tes

To
preser vethe engine during thefirst
10 00 mile s (1500 km):
R drive at varying road speeds and engine
speeds.
R drive theve hicle in drive program A
or ;.
R change gear before theta ch ome ter needle is
00C3 ofthewa yto there d area of theta ch ome‐
te r.
R do not shift down a gear manually in order to
brake.
R avoidoverstra ining theve hicle, e.g. driving at
full thro ttle.
R do not depress the accelera tor pedal past
th e pressure point (kickdown).
R only increase the engine speed gradually and
accelera tetheve hicle tofull speed af ter
10 00 miles (1500 km).
This also applies when the engine or parts of the
driv etra in ha vebeen replaced. Please also obser

R in cer tain driving and driving saf ety sy stems,
th e sensors adjust automatically while a cer‐
ta in dis tance is being driven af terth eve hicle

end of this teach-in process.
R brakepads, brake discs and tires that are

WARNING Risk of accident due to
objects in the driver's foot we ll
Objects in the driver's foot we ll may impede
pedal tra vel or block a depressed pedal.
This jeopardizes the operating and road
saf ety of theve hicle. #
Stow all objects in theve hicle securely
so that they cannot getinto the driver's

and as prescribed in order toensure
th at there is alw ays suf ficient room for
th e pedals. #
Do not use loose floor mats and do not
place floor mats on top of one ano ther. &

regulates the brake pressure in critical driv‐
ing situations:
R During braking, e.g. at full brake application
or insuf ficient tire traction, the wheels are
pr eve nted from lo cking.
R Vehicle steerability while braking is ensured.
If ABS inter venes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous
road
conditions and can ser veas a reminder totake
ex tra care while driving.

Sy stem limitations
The sy stem may be impaired or may not function
in thefo llowing situations:
R In sno w,rain, fog, heavy spr ay, if there is
gl are, in direct sunlight or in greatlyvarying
ambient light.
R Ifth e sensors are dirty, fogged up, damaged
or co vered.
R Ifth e sensors malfunction due to otherradar
source inter fere nce, forex ample strongradar
re flections in parking garage s.
R If a loss of tire pressure or a defective tire
has been de tected and displ ayed.
The sy stem may not react cor rectly:
R In compl extraf fic situations whe reobjects
cannot always be clearly identified. R
Topedestrians or vehicles if they mo ve
qu ickly into the sensor de tection range.
R Topedestrians who are hidden by other
objects.
R Ifth e typical outline of a pedestrian cann ot
