restraint system. There is arisk of injury.
If you leave the vehicle, taking the child with
you ,alway sensure that the child restraint
system is not exposedtod irect sunlight. Pro-
tect it with ablanket, for example. If the child
restraint system has been exposedtod irect
sunlight, let it cool downb efore securing the
child in it. Never leave children unattended in
the vehicle.
Always ensure that all vehicleo ccupants have
their seat belts fastened correctly and are sitting
properly.P articular attention must be pai dto
children.

ABS (Anti-lock Brakin gSystem)
General information
ABS regulate sbrake pressure in such awaythat
the wheels do not lock when yo ubrake. This
allows yo utocontinue steering the vehicl ewhen
braking. The
! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goe soutwhen the engine is running.
ABS works from aspeed of about5m ph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, eve nwheny ou
onlyb rake gently.
Important safety notes
iObserve the "Important safety notes "sec-
tio n(Ypage 61).
GWARNING
If ABS is faulty ,the wheels could lock when
braking .The steerability and braking charac-
teristic smaybe severely impaired.A ddition-
ally ,further driving safety systemsa re deac-
tivated.T here is an increased danger of skid-
ding and accidents.
Driv eonc arefully. Hav eABS checked imme-
diately at aquali fied specialist workshop.
Whe nABS is malfunctioning ,othe rsystems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 220 )and dis-
play messages which maybes hown in the
instrument cluster (
Ypage 192).
Braking
XIf ABS intervenes: continue to depress the
brake peda lvigorously unti lthe braking sit-
uatio niso ver.
XTo make afullb rake application: depress
the brake peda lwithf ullf orce.
If ABS intervene swhenb raking ,you will fee la
pulsing in the brake pedal.
The pulsating brake peda lcan be an indication
of hazardousr oadconditions, and functions as a
reminder to take extra car ewhile driving.
BAS (Brak eAssis tSystem)
General information
BAS operates in emergency braking situations.
If yo udepress the brake peda lquickly, BAS
automaticall yboosts the braking force,t hus
shortening the stopping distance.

Z

The distance warning function may not give
warnings in all critical situations. There is a
risk of an accident.
Always pay careful attention to the traffic sit-uation and be ready to brake.
Always adapt your speed to suit the prevailing
road and traffic conditions.
GWARNING
The distance warning function cannot always
clearly identify object sand complex traffic
situations.
In such cases, the distance warning function
may:
Rgive an unnecessary warning
Rnot give awarning
There is arisk of an accident.
Always pay careful attention to the traffic sit-
uation and do not rely solely on the distance
warning function.
Function
Starting at aspeed of approximately 4mph
(7 km/h), the distance warning function warns
you if you rapidly approach avehicle in front.A n
intermittent warning ton ewill then sound, and
the · distance warning lamp will light up in
the instrument cluster.
XBrake immediately in order to increase the
distance from the vehicle in front.
or
XTake evasive action, provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause the system to display awarning.
With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to aspeed of approximately 44 mph
(70 km/h), the distance warning function can
also react to stationary obstacles, such as stop-
ped or parked vehicles.
Autonomous braking function
If the driver does not react to the distance warn-
ing signal in acritical situation, Active Brake
Assist can assist the driver with the autonomous
braking function.
The autonomous braking function:
Rgives the driver more time to react to critical
driving situations
Rcan help the driver to avoid an accident or
Rreduces the effectsofana ccident
Vehicles without Distance Pilot DISTRONIC: the autonomous braking function is available in
the following speed ranges:
R4-65m ph (7-105 km/h) for moving objects
R4-31mph (7-50km/h)for stationary
objects
Vehicles with Distance Pilot DISTRONIC: the
autonomous braking function is available in the
following speedr anges:
R4-124 mph (7 -200 km/h )for moving
objects
R4-31m ph (7-50km/h)for stationary
objects
Due to the nature of the system ,particularly
complicated but non-critical driving conditions
may als ocaus ethe Autonomou sBraking Func-
tion to intervene.
Situation-dependent braking assis-
tance
General information
iObservet he "Important safety notes" sec-
tion (Ypag e61).
With the help of the rada rsensor system ,Adap-
tive Brake Assist can detect obstacles that are in
the path of you rvehiclef or an extended period
of time.
If Adaptive Brake Assist detects arisk of colli-
sion with the vehicleinf ront, it calculatesthe
brake pressure necessary to avoi dacollision. If
you apply the brakes forcefully ,situation-
dependent braking assistance adapts to the sit-
uation and automatically increases the brake
pressure to adegreea ppropriate to the traffic
situation.
