to a load in an accident can no longer protect
as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There
is an increased risk of injury, possibly even
fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the secur-
ing systems on the child restraint system
checked at a qualified specialist workshop,
before you install a child restraint system
again.
The securing systems of child restraint sys-
tems are: R
the seat belt system R
the LATCH-type (ISOFIX) securing rings R
the Top Tether anchorages
If it is absolutely necessary to carry a child on
the front-passenger seat, be sure to observe
the information on the "Occupant Classifica-
tion System (OCS)" ( Y
page 53). There you
will also find information on deactivating the
front-passenger front air bag.
All child restraint systems must meet the fol-
lowing standards: R
U.S. Federal Motor Vehicle Safety Stand-
ards 213 and 225 R
Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found
o n
an instruction label on the child restraint
system. This confirmation can also be found
in the installation instructions that are inclu-
ded with the child restraint system.
Observe the warning labels in the vehicle inte-
rior and on the child restraint system. LATCH-type (ISOFIX) child seat secur-
ing system
G WARNING
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg) who are secured using the safety belt
integrated in the child restraint system. In the
event of an accident, a child might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is also secured
with the vehicle seat belt. Also secure the
child restraint system with the Top Tether
belt, if available.
Always comply with the manufacturer's
installation and operating instructions for the
child restraint system used.
Before every trip, make sure that the LATCH-
type (ISOFIX) child restraint system is
engaged correctly in both LATCH-type (ISO-
FIX) securing rings
To ensure that the LATCH-type (ISOFIX) child
restraint system can perform its protective
function as intended, the backrest of the
respective outer seat in the second row must
be in the upright position.
! When installing the child restraint system,
make sure that the seat belt for the middle
seat does not get trapped. The seat belt
co u ld otherwise be damaged.Children in the vehicle 63

ISOFIX is a standardized securing system for
specially designed child restraint systems on
the rear seats. Non-LATCH-type (ISOFIX) child seats may
also be used and can be installed using the
vehicle's seat belt system. Install the child
seat according to the manufacturer's instruc-
tions.
Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured
with a LATCH-type (ISOFIX) child seat mount
and the vehicle. This helps reduce the risk of
injury even further. If the child restraint sys-
tem is equipped with a Top Tether belt, this
should always be used.
Important safety notes
G WARNING
If the rear seats or the rear seat backrests are
not locked, they could fold forwards in the
event of an accident, heavy braking or sudden
changes of direction. As a result, child
restraint systems cannot perform their inten-
ded protective function. Rear seats and rear
seat backrests that are not locked can also
cause additional injuries, e.g. in the event of
an accident. This poses an increased risk of
injury or even fatal injury.
Always lock the rear seats and rear seat
backrests after installing a Top Tether belt.
Observe the lock verification indicator. Adjust
the rear seat backrests so that they are in an
upright position.
If the rear seat backrest is not engaged and
locked, this will be shown in the multifunction
display in the instrument cluster.64

ted.
Always observe the child restraint system
manufacturer's installation and operating
instructions.
Forward-facing child restraint system If it is absolutely necessary to install a
forward-facing child restraint system on the
front-passenger seat, always move the front-
passenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat. The child restraint system must not
touch the roof or be subjected to a load by the
head restraint. Adjust the angle of the seat
backrest and the head restraint position
accordingly. Always make sure that the shoul-
der belt strap is correctly routed from the
vehicle belt outlet to the shoulder belt guide
on the child restraint system. The shoulder
belt strap must be routed forwards and down-
wards from the vehicle belt outlet. If neces-
sary, adjust the vehicle belt outlet and the
front-passenger seat accordingly.

Important safet y notes
If you fail to adapt your drivin g style or if you
are inattentive , th e drivin g safet y systems can
neither reduce th e ris k of an acciden t no r
override th e laws of physics. Driving safet y
systems are merely aids designed to assist
driving. You are responsible fo r maintainin g
th e distanc e to th e vehicle in front, fo r vehicle
speed, fo r braking in goo d time, and fo r stay-
in g in lane. Always adapt your drivin g style to
suit th e prevailin g road and weather condi-
tion s and maintain a saf e distanc e from th e
vehicle in front. Drive carefully.
The drivin g safet y systems described only
wor k as effectively as possible when there is
adequat e contact between th e tires and th e
road surface. Please pay special attention to
th e note s on tires , recommended minimum
tire tread depths, etc. ( Y
page 404).
In wintr y drivin g conditions, always use winte r
tires (M+ S tires ) and if necessary, snow
chains. Only in this way will th e drivin g safet y systems described in this section wor k as
effectively as possible.
ABS (Anti-lock Braking System)
General information AB S regulates brake pressure in suc h a way
that th e wheels do no t loc k when you brake .
Thi s allow s you to continue steerin g th e vehi-
cl e when braking .
The % AB S warnin g lamp in th e instrumen t
cluster lights up when th e ignition is switched
on . It goe s out when th e engin e is running .
AB S works from a speed of about 5 mph
(8 km/h), regardles s of road-surfac e condi-
tions. AB S works on slipper y surfaces, eve n
when you only brake gently.
Important safet y notes

G WARNING
If AB S is faulty, th e wheels could loc k when
braking . The steerability and braking charac -
teristics may be severely impaired. Addition -
ally, further drivin g safet y systems are deac -
tivated. There is an increase d danger of skid-
din g and accidents .
Drive on carefully. Hav e AB S checke d imme-
diately at a qualified specialis t workshop .

Driving safety systems
Safety

If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving.
Off-road ABS A 4ETS system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated ( Y
page 258).
At speeds below 20 mph (30 km/h), the front
wheels lock cyclically during braking. The dig-
ging-in effect achieved in the process reduces
the stopping distance on off-road terrain. This
limits steering capability.
BAS (Brake Assist System)
General information BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 68).
G WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. BAS PLUS (Brake Assist System
PLUS)
General information BAS PLUS can help you to minimize the risk of
a collision with a vehicle or reduce the effects
of such a collision. If BAS PLUS detects a
danger of collision, you are assisted when
braking.
i Observe the "Important safety notes" sec-
tion ( Y
page 68).
BAS PLUS is only available in vehicles equip-
ped with DISTRONIC PLUS.
For BAS PLUS to assist you, the radar sensor
system must be operational.
With the help of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
If the radar sensor system is malfunctioning,
BAS PLUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS.
Important safety notes
G WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BAS PLUS may: R
intervene unnecessarily R
not intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
G WARNING
BAS PLUS does not react: R
to people or animals R
to oncoming vehicles R
to crossing traffic R
when corneringDriving safety systems 69
Safety Z

As a result, BAS PLUS may not intervene in all
critical situations. There is a risk of an acci-
dent.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In the event of snowfall or heavy rain, the rec-
ognition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of: R
there is dirt on the sensors or anything else
covering the sensors R
there is interference by other radar sources R
there are strong radar reflections, for
example in parking garages R
a narrow vehicle traveling in front, e.g. a
motorbike R
a vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.
Function
To avoid a collision, BAS PLUS calculates the
brake force necessary if: R
you approach an obstacle, and R
BAS PLUS has detected a risk of collision
When driving at a speed under 20 mph
(30 km/h) : if you depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last possi-
ble moment.
When driving at a speed above 20 mph
(30 km/h) : if you depress the brake pedal
sharply, BAS PLUS automatically raises the
brake pressure to a value adapted to the traf-
fic situation.
BAS PLUS provides braking assistance in haz-
ardous situations with vehicles in front within a speed range between 4 mph (7 km/h) and
155 mph (250 km/h).
At speeds of up to approximately 40 mph
(70 km/h), BAS PLUS can also react to sta-
tionary objects. Examples of stationary
objects are stopped or parked vehicles.
i If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE ®
) are activa-
ted simultaneously. X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual again, if: R
you release the brake pedal. R
there is no longer a risk of collision. R
no obstacle is detected in front of your
vehicle.
If you have activated DSR ( Y
page 257), BAS
PLUS is likewise deactivated.
COLLISION PREVENTION ASSIST
