PRE-SAFE®(anticipatory occupant
protection system)
Introduction
PRE-SAFE®takes preemptive measures to
protect occupants in certain hazardous
situations.
Important safety notes
!Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
Despite your vehicle being equipped with the
PRE-SAFE®system, the possibility of
personal injuries occurring as a result of an
accident cannot be eliminated.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function
PRE-SAFE®intervenes:
Rin emergency braking situations, e.g. when
BAS is activated.
Rin critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely.
Ron vehicles with DISTRONIC PLUS:if
BAS PLUS brakes hard or the radar sensor
system detects an imminent danger of
collision in certain situations.
PRE-SAFE®takes the following measures
depending on the hazardous situation
detected:
Rthe front seat belts are pre-tensioned.
Rif the vehicle skids, the sliding sunroof and
the side windows are closed so that only a
small gap remains. On vehicles with a
panorama roof with power tilt/sliding
panel, they are closed completely.

(ISOFIX) child restraint systems are installed
on the left and right:
Ron the rear seat backrests of the outer
seats in the second row
Ron the backrests of the seats in the third

Before installing a LATCH-type (ISOFIX) child
restraint system in the second row:
XMove the rear seat backrests in the second
row to an upright position (Ypage 111).
XInstall the LATCH-type (ISOFIX) child
restraint system on both LATCH-type
(ISOFIX) securing ringsD. Comply with the
child restrain system manufacturer's
instructions when installing the LATCH-
type (ISOFIX) child restraint system.
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
instructions.
Top Tether
Top Tether anchorages
GWARNING
If 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 intended protective
function. 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 rear seat backrests after
installing a Top Tether belt. Observe the lock
verification indicator. Adjust the rear seat
backrests so that they are positioned
vertically.
Top Tether provides an additional connection
between the LATCH-type (ISOFIX) child
restraint system secured with LATCH-type
(ISOFIX) and the rear seat. This helps reduce
the risk of injury even further. If the LATCH-
type (ISOFIX) child restraint system is
equipped with Top Tether, this should always
be used.
The Top Tether anchorages for the second
row of seats are installed on the rear of the
rear seat backrests. For the third row of seats,
use the cargo tie-down rings in the cargo
compartment floor.
If the rear seat backrest is not engaged and
locked, this will be shown in the multifunction
display in the instrument cluster.

Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road and weather
conditions and maintain a safe distance from
the vehicle in front. Drive carefully.
iThe driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special
attention to the notes on tires,
recommended minimum tire tread depths,
etc. (Ypage 404).
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 a way
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.
Important safety notes
iObserve the "Important safety notes"
section (Ypage 67).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified 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 326) and
display messages which may be shown in the
instrument cluster (Ypage 291).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery surfaces,
even when you only brake gently.
Braking
XIf ABS intervenes:continue to depress the
brake pedal vigorously until the braking
situation is over.
XTo make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.

You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps (Ypage 327) as well as
display messages (Ypage 293).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
(Ypage 216) and hill start assist
(Ypage 171).
PRE-SAFE®Brake
General information
iObserve the "Important safety notes"
section (Ypage 67).
PRE-SAFE®Brake is only available in vehicles
with DISTRONIC PLUS.
For PRE-SAFE®Brake to assist you when
driving, the radar sensor system must be
operational.
With the help of the radar sensor system,
PRE-SAFE®Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
PRE-SAFE®Brake can help you to minimize
the risk of a collision with a vehicle ahead, and
reduce the effects of such a collision. If PRE-
SAFE®Brake has detected a risk of collision,
you will be warned visually and acoustically
as well as by automatic braking. PRE-SAFE®
Brake cannot prevent a collision without your
intervention.
Important safety notes
GWARNING
PRE-SAFE®Brake will initially brake your
vehicle by a partial application of the brakes
if a danger of collision is detected. There may
be a collision unless you also brake.
Automatic emergency braking cannot prevent
a collision. There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action.
GWARNING
PRE-SAFE®Brake cannot always clearly
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE®Brake may:
Rgive an unnecessary warning and then
brake the vehicle
Rnot give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE®Brake warns you. Terminate the
intervention in a non-critical driving situation.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
GWARNING
PRE-SAFE®Brake does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
As a result, PRE-SAFE®Brake may neither
give warnings nor intervene in all critical
situations. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In the event of snowfall or heavy rain, the
recognition can be impaired.
