If you fail to adapt your driving style or if you
are inattentive, th edriving safety systems can
neither reduc ethe riskofana ccidentnor
override th elaws of physics. Drivin gsafety
systems are merely aids designe dtoassist
driving .You are responsible for maintaining
th ed istanc etothevehicle in front, for vehicle
speed, for braking in good time, and for stay- ing in lane .Always adapt your driving style to
suit th eprevailin groad and weather condi-
tions and maintain asafe distanc efromt he
vehicle in front. Drive carefully.
The driving safety systems describe donly
work as effectivel yaspossible when there is
adequat econtac tbetween th etyres and the
road surface. Pleas epay special attentio nto
th en otes on tyres, recommended minimum
tyr etread depths etc. (Y page 416).
In wintry driving conditions, always use winter
tyres (M+ Styres) and ,ifnecessary, snow
chains .Onlyint hisw ay will th edriving safety
systems describe dinthiss ectio nwork as
effectivel yaspossible. ABS (Anti-lock Braking System)

WARNING
If ABS is faulty, the wheels coul dlock when
braking. The steerability and braking charac-
teristics may be severely impaired .Addition-
ally, further driving safety systems are deac-
tivated. There is an increased dange rofskid-
ding and accidents.
Drive on carefully.H ave ABS checked imme-
diately at aqualified specialist workshop.
If ABS is malfunctioning, other systems,
including driving safety systems ,willa lso
become inoperative. Observe the information on the ABS warning lamp (Y page332) and
display messages which may be show ninthe
instrument cluster (Y page300).
ABS works from aspee dofa bout8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you
only brake gently.
Brakes X
If ABS intervenes: continue to depress the
brake peda lwith force until the braking sit-
uation is over.
X To make afull brake application:
depress the brake peda lwith full force.
If ABS intervenes when braking, you willf eel a
pulsing in the brake pedal.
The pulsating brake peda lcan be an indica-
tion of hazardous road conditions; this serves
as areminde rtotake extra care while driving. BAS (Brake Assist System)
General notes BAS operates in emergency braking situa-
tions. If you depress the brake peda lquickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance. Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page77). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is arisk of accident.
In an emergency braking situation, depress
the brake peda lwith full force. ABS prevents
the wheels from locking.
Brakes X
Keep the brake peda ldepressed firmly until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes willf unction as usual once you
release the brake pedal. BAS is deactivated. BAS PLUS(
Brake Assist System
PLUS) with Cross-Traffic Assist
General notes i
Observe the "Important safety notes" sec-
tion (Y page77).
BAS PLUS is only available on vehicles with
the Driving Assistance package.
For BAS PLUS to assist you when driving, the
rada rsensor system and the camera system
must be operational.
With the help of asensor system and acam-
era system, BAS PLUS can detect obstacles:
R that are in the path of yourv ehiclefor an
extended period of time
R that cross the path of yourv ehicle
In addition, pedestrians in the path of your
vehicl ecan be detected.
BAS PLUS detects pedestrians using typical
characteristics such as the body contours
and posture of aperso nstanding upright.
If the rada rsensor system or the camera sys-
tem is malfunctioning, BAS PLUS functions
are restricted or no longer available.T he78
Driving safety systemsSafety
When driving at
aspee dabove 30 km/h :if
you depress the brake peda lsharply,B AS
PLUS automatically increases the brake pres- sure to adegre esuited to the traffic situation.
BAS PLUS provides braking assistance in haz- ardous situations with vehicles in front within
as pee drange between 7km/h and
250 km/h.
Up to aspee dofa pproximately 70 km/h, BAS
PLUS may react to:
R stationary objects in the path of yourv ehi-
cle, e.g. stoppe dorparked vehicles
R pedestrians in the path of yourv ehicle
R obstacles crossing yourp ath, which move
in the detection range of the sensors and
are recognised by them
i If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE ®
)a re activa-
ted simultaneously.
X Keep the brake peda ldepressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual, if:
R you release the brake pedal
R there is no longer arisk of collision
R no obstacl eisdetected in front of your
vehicle
R you depress the accelerator pedal
R you activate kickdown COLLISIONP
REVENTIONASSIST
PLUS
General notes COLLISION PREVENTIO
NASSIST PLUS con-
sists of adistance warning function with an
autonomous braking function and Adaptive
Brake Assist.
COLLISION PREVENTIO NASSIST PLUS can
help you to minimise the risk of acollision with the vehicl
einfront or reduce the effects
of such acollision.
If COLLISION PREVENTIO NASSIST PLUS
detects that there is arisk of acollision, you
willbew arned visuallya nd acoustically.Ify ou
do not react to the visual and audible collision warning, autonomous braking can be initiated
in critical situations. If you apply the brake
yourself in acritical situation, the COLLISION
PREVENTIO NASSIST PLUS Adaptive Brake
Assist assists you.
Switchin gthe soun don/off COLLISION PREVENTIO
NASSIST PLUS is
activated after every ignition cycle .You can
activate or deactivate COLLISION PREVEN-
TION ASSIST PLUS in the on-board computer
(Y page2 87). When deactivated, the dis-
tance warning function and the autonomous
braking function are alsod eactivated.
If COLLISION PREVENTIO NASSIST PLUS is
deactivated, the æsymbol appears in the
assistance graphics display.
Important safety notes In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other rada rsources
R strong rada rreflections, for example, in
multi-storey car parks
R an arrow vehicl etravelling in front, e.g. a
motorcycle
R av ehicl etravelling in front on adifferent
line
R new vehicles or after aservice on the COL-
LISION PREVENTIO NASSIST PLUS system
Please observe the information in the sec-
tion on running-in the vehicle
(Y page1 78).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the rada rsensor checked at aqualified spe- 80
Driving safety systemsSafety
The autonomous braking function is available
in the following speed ranges:
R from 7km/ htoa pprox. 105 km/hf or mov-
ing objects
R from 7km/ htoa pprox. 50 km/h for sta-
tionar yobjects
If the autonomou sbraking functio ndeman ds

If Adaptive Brake Assist detects ariskofc ol-
lision with the vehicl einfront, it calculates

WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent the vehicle/trailer combination from swerv- ing. Trailers with
ahigh centre of gravity can
tip over before ESP ®

ar isk of an accident.
Always adapt your driving style to the prevail- ing road and weather conditions.
If your vehicle/trailer combination begins to
