Always pay careful attention to the traffic
situationand be ready to brake.
The distance warning functioncannot always
clearly identify objects and complextraffic
situations.
In such cases, the distance warning function
may:
Rgive an unnecessary warning
Rnot give a warning
Always pay careful attention to the traffic
situation and do not rely solely on the
distance warning function.
Function
XTo activate/deactivate:activate or
deactivate the distance warning function in
the on-board computer (Ypage 204).
If the distance warning function is not
activated, the
symbol appears in the
assistance graphics display.
The distance warning function can help you
to minimize the risk of a front-end collision
with a vehicle ahead or reduce the effects of
such a collision. If the distance warning
function detects that there is a risk of a
collision, you will be warned visually and
acoustically.Without your intervention, the
distance warning function cannot prevent a
collision.
Starting at a speed of around 4 mph
(7 km/h) the distancewarning function warns
you if you rapidly approach a vehicle in front.
An intermittentwarning tone will then sound,
and thedistance 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 provideditis safe to do
so.
For the distance warning function to assist
you when driving, the function must be
activated in the on-board computer and be
operational (Ypage 204).
Due to the nature of the system, particularly
complicated but non-critical driving
conditions may also cause the system to
display a warning.
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 extended period of time.
From a speed of around 40 mph (70 km/h),
the distance warning function can also react
to stationary obstacles, such as stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain
Rinterference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
Adaptive Brake Assist
iObserve the "Important safety notes"
section for driving safety systems
(Ypage 61).
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic
situations. In these cases, Adaptive Brake

Z

Assist may not intervene. There is a riskofan
accident.
Always pay careful attention to the traffic
situationand be ready to brake.
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rto stationary obstacles
Rwhen cornering
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic
situationand be ready to brake.
Due to the nature of the system, particularly
complicated but non-critical driving
conditions may also cause Brake Assist to
intervene.
Adaptive Brake Assist aids you in braking
during hazardous situations at speeds above
4mph (7 km/h) and uses the radar sensor
system to evaluate the traffic situation.
With the help of a sensorsystem, adaptive
Brake Assistcan detect obstacles that are in
the path of your vehicle for an extended
period of time.
Should you approach an obstacle and
Adaptive Brake Assist has detected a riskof
collision, Adaptive Brake Assist calculates the
braking force necessary to avoid a rear-end
collision. Should you apply the brakes
vigorously, Adaptive Brake Assist will
automatically increase the braking force to a
level suitable for the traffic conditions.
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally againif:
Ryou release the brake pedal
Rthere is no longerany dangerofarear-end
collision.
Rno obstacle is detected in front of your
vehicle
Adaptive Brake Assist is then deactivated.
Up to vehicle speeds of around 155 mph
(250 km/h), adaptive Brake Assist is capable
of reacting to moving objects that have
already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due
to a malfunction in the radar sensor system,
the brake system remains available with full
brake boosting effect and BAS.
In particular, the detection of obstacles can
be impaired if there is:
Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain
Rinterference by other radarsources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
COLLISION PREVENTION ASSIST PLUS
General information
COLLISION PREVENTION ASSIST PLUS is
only available on vehicles with DISTRONIC.
COLLISION PREVENTION ASSIST PLUS
extends the functionality of COLLISION
PREVENTION ASSIST with an automatic

Safety

braking function. COLLISION PREVENTION
ASSIST PLUS can help you to minimize the
risk of a front-end collision with a vehicle
ahead or reduce the effects of such a
collision. If COLLISION PREVENTION ASSIST
PLUS detects that thereis a risk of a collision,
you will be warned visually and acoustically.
In critical situations COLLISION PREVENTION
ASSIST PLUS also initiates automatic
braking.
Function
XTo activate/deactivate:activate or
deactivate COLLISION PREVENTION
ASSIST PLUS in the on-board computer
(Ypage 204).
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the
symbol appears in the
assistance graphics display.
If the driver's seat belt is fastened,
COLLISION PREVENTION ASSIST PLUS can
brake automatically withinaspeed range of
between 4 mph (7 km/h) and 124 mph
(200 km/h).
COLLISION PREVENTION ASSISTPLUS can
also react to stationary obstacles with
automatic braking within a speed range of
between 4 mph (7 km/h) and 19 mph
(30 km/h).
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain
Rinterference by other radarsources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line

Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes"
section (Ypage 61).
ESP®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP®assists the driver when
pulling away on wet or slippery roads. ESP®
can also stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System)
iObserve the "Important safety notes"
section (Ypage 61).
ETS/4ETS traction control is part of ESP®.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel or wheels with traction.
ETS remains active when you deactivate
ESP®.
Important safety notes
GWARNING
If ESP®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP®checked at a
qualified specialist workshop.
