In order to avoid such risks, always ensure
that all vehicle occupants:
R fasten their seatbelts correctly, including
pregnant women
R are seated correctly and maintain the fur-
thest possible distance from the airbags
R observe the following notes
Alwayse nsure that there are no objects loca-
ted betwee nthe airbag and the vehicle occu-
pant.
R Adjust the seats properl ybefore beginning
yourj ourney. Alwaysm ake sure that the seat
is in an almostu pright position. The centre of
the head restraint must support the head at
aboute ye level.
R Move the driver's and front-passenger seats
as far back as possible. The driver's seat posi- tion must allow the vehicle to be driven safely.
R Only hold the steering wheel on the outside.
This allows the airbag to be fullyd eployed.
R Alwaysl eana gainst the backrest whiled riv-
ing. Do not leanf orwardsorleana gainst the
door or side window .You may otherwise be in
the deployment area of the airbags.
R Alwaysk eep yourf eet in the footwell in front
of the seat. Do not put yourf eet on the dash-
board,f or example .Your feet may otherwise
be in the deployment area of the airbag.
R Alwayss ecure persons less than 1.50 mtall in
suitable restraint systems .Uptothish eight,
th es eat belt canno tbeworn correctly.
If ac hild is travelling in your vehicle, also
observe th efollowin gnotes:
R Always secure childre nunde rtwelve years old

WARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may push abutton
or as witch, for example.
They could:
R activate vehicle equipment and become
trapped, for example
R switch vehicle systems on or off, thus
endangering other road users
In the event of an accident, sudden braking or
abrupt changes of direction, unsecured ani-
mals could be flung around the vehicle, injur-
ing the vehicle occupants. There is arisk of an

the following driving safety systems:

R STEERC ONTROL (Y page 77) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front,f or vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather condition sand maintain asafe distance
from the vehicle in front.D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tyres and the road
surface. Pay particular attention to the informa- tion regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and tyres" section (Y page 353).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-loc
kBraking System)
General notes ABS regulates brake pressure in such
away that
the wheels do not lock when you brake. This
allowsy ou to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from aspeed of about 8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristic smay be severely impaired. Addition-

tions.
In such cases, Adaptiv eBrakeA ssist can:
R interven eunnecessarily
R not intervene
There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the

WARNING
Adaptiv eBrakeA ssist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As aresult, the Adaptiv eBrak eAssist may not

risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
Due to the natur eofthe system, particularly
complicated but non-critical driving conditions
may also cause Brak eAssist to intervene.
If Adaptiv eBrak eAssist is not available due to a
