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
accident and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals correctly during a
journey, e.g. in an animal transport box. Driving safety systems
Driving safety systems overview
In this section,y ou will find information about
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-
ally,f urther driving safety systems are deac- 66

If ABS intervenes when braking ,you will fee la
pulsing in the brake pedal.
The pulsating brake peda lcan be an indication
of hazardous roa dconditions ;thiss erve sasa
reminder to take extra car ewhile driving. BAS (Brak

General notes BAS operates in emergency braking situations.
If yo udepress the brake peda lquickly, BAS
automaticall yboosts the braking force, thus
shortening the stopping distance.

Adaptiv eBrakeA ssist provides brakin gassis-

assess the traffic situation.
Up to aspeed of approximately 250 km/h,

WARNING
Adaptiv eBrakeA ssist cannot always clearly
identify objects and complex traffic situa-
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
intervention in anon-critical driving situation. G
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
interven einall critical conditions. There is a
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
malfunction in the radar sensor system, the
brake system remains available with full brake
boostin geffec tand BAS. Adaptive brake lights
The adaptive brake lights warn following traffic
in an emergency brakin gsituation:
R by flashing brake lamps
R by activating the hazard warning lamps
If you brake sharply from aspeed of more than
50 km/ horifb raking is assisted by BAS or BAS
PLUS, the brake lamp sflashr apidly.Int his way,
traffic travelling behind you is warned in an even more noticeable manner.
If you brake sharply from aspee dofm ore than
70 km/h to astandstill, the hazard warning
lamp sare activated automatically. If the brakes
are applieda gain, the brake lamp slight up con-
