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 vehicl eequipment and become
trapped, for example
R switch vehicl esystems on or off, thus
endangering other road users
In the event of an accident, sudden braking or
abrupt changes of direction, unsecured ani-
mals coul dbeflung around the vehicle, injur-
ing the vehicl eoccupants. 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 anima ltransport box. Driving safe

If you fail to adapt your driving style or if you are
inattentive, th edriving safet ysystems can nei-

th el aws of physics .Drivin gs afet ysystems are
merely aids designed to assist driving .You are
responsible for maintainin gthe distanc etothe
vehicl einfront,for vehicl espeed, for braking in
goo dtime, and for staying in lane. Always adapt
your driving style to suit th eprevailing road and weather conditions and maintain
asafe distance
fro mt hevehicle in front .Drive carefully.
The driving safet ysystems described work as
effectively as possible only when there is ade-
quate contac tbetween th etyres and th eroad
surface. Pay particular attention to th einforma-
tio nr egarding tyres, recommended minimum
tyr etread depths etc .inthe"Wheels and tyres"
sectio n(Ypage 235).
In wintry driving conditions ,always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will th edriving safety
systems described in this sectio nwork as effec-
tively as possible. ABS (Anti-lock Braking System)
Genera linformation AB
Sregulate sbrake pressure in such awaythat
the wheels do not lock when yo ubrake. This
allows yo utocontinue steering the vehicl ewhen
braking.
The yellow !ABS warning lamp in the instru-
ment cluster lights up when the ignition is
switched on. It goe soutwhen the engine is run-
ning.
ABS works from aspeed of abou t8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces ,evenw heny ou

WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired.A ddition-
ally, further driving safety systems are deac-
tivated. There is an increased dange rofskid-
ding and accidents.

General notes i
Observ

tion (Y page 52).
ESP ®
monitors driving stability and traction, i.e.
power transmission between the tyres and the
road surface.
If ESP ®
detects that the vehicle is deviating from
the direction desired by the driver, one or more
wheels are braked to stabilise the vehicle. The
engine output is also modified to keep the vehi- cle on the desired course within physical limits.
ESP ®
assists the driver when pulling awayon
wet or slippery roads. ESP ®
can also stabilise
the vehicle during braking. Driving safe

ethe "Important safety notes" sec-
tion (Y page 52).
4ETS traction control is part of ESP ®
.
4ETS traction control is no longer active above a
speed of approximately 60 km/h.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
awaya nd accelerate on slippery surfaces, e.g. if
the road surface is slippery on one side. In addi-
tion, more drive torque is transferred to the
wheel or wheels with traction.
Traction control remains active if you deactivate
ESP ®

tion (Y page 52). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully.H ave ESP®

Observe the information on warning lamps
(Y page1 59) and display messages which may
be displayed in the instrument cluster
(Y page1 42). Use only wheels with the recommended tyre
sizes. Only then will ESP ®
