good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and
weather conditions and maintainasafe 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 tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section (
Ypage 255).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such away that
the wheels do not lock when you brake. This
allows you 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 5mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 54).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally,f urther driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at aqualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 204) and dis- play messages which may be shown in the
instrument cluster (
Ypage 179).
Braking
XIf ABS intervenes:
continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo make afull brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a reminder to take extr acare while driving.
BAS (Brake Assist System)
General information
BAS operates in emergencyb raking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 54).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergencyb raking situation is
increased. There is arisk of an accident.
In an emergencyb raking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking
XKeep the brake pedal firmly depressed until
the emergencyb raking situation is over.
ABS prevent sthe wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.

Due to th enature of th esystem, particularly
co mpli cated but non-critical driving conditions
may also caus ethe system to displayaw arning.
Witht hehelp of th eradar sensor system, the
dist ancewarning function can detect obstacles
that are inthep athofy our veh iclefor an exten-
ded period of time.
Up to aspeedofa pproximately 44 mph
(70 km/ h),t he distance warnin gfunction 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
Assis tcan assist with the autonomous braking
function.
If the autonomous brakin gfunction requires a
particularly high brakin gforce, preventative
passenger protection measures (PRE-SAFE
®)
are activated simultaneously.
Vehicles without Distance Pilot DISTRONIC:
the autonomous brakin gfunction is available in
the following speed ranges:
R4-65m ph (7-105 km/ h)for moving objects
R4-31m ph (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. If the autonomous braking function requires a
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
®)
are activated simultaneousl y(Ypage51).
Adaptive Brake Assist
General information
iObservet he "Important safety notes" sec-
tion (Ypag e54).
With the help of adaptive Brake Assist, the dis-
tance warning signa lcan 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 vehicl einfront, it calculate sthe
braking force necessary to avoi dacollision. If
you apply the brakes forcefully ,adaptive Brake
Assist wil lautomatically increas ethe braking
force to alevels uitabl efor the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardouss ituations at speeds above
4m ph (7 km/h) .Itusesrada rsensor technology
to assess the traffic situation.
Up to aspeedofa pproximately 155 mph
(250 km/h) ,adaptive Brake Assist is capable of
reacting to moving objects that have already
been detected as such at least once over the
period of observation.
Up to aspeedofa pproximately 44 mph
(70 km/h), adaptive Brake Assist reacts to sta-
tionary obstacles.
If adaptive Brake Assist demands particularly
high braking force, preventative passenger pro-
tection measures (PRE-SAFE
®)a re activated
simultaneousl y(Ypage51).
XKeep the brake pedald epressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes wil lwork normally again if:
Ryou release the brake pedal.
Rthere is no longe rany dange rofacollision.
