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 a critical situation, COLLISION PRE-
VENTION ASSIST PLUS can assist with the
autonomous braking function.
Vehicles without DISTRONIC PLUS: the
autonomous braking function is available in the
following speed ranges:
R4–65 mph (7–105 km/h) for moving objects
R4–31 mph (7–50 km/h) for stationary objects
Vehicles with DISTRONIC PLUS: the autono-
mous braking function is available in the follow-
ing speed ranges:
R4–124 mph (7–200 km/h) for moving objects
R4–31 mph (7–50 km/h) for stationary objects
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause the Autonomous Braking Func-
tion to intervene.
If the autonomous braking function requires a
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
®)
are activated simultaneously (Ypage 57).
Adaptive Brake Assist
General information
iObserve the "Important safety notes" sec-
tion (Ypage 65).
With the help of adaptive Brake Assist, the dis-
tance warning signal can detect obstacles that
are in the path of your vehicle for an extended
period of time.
If adaptive Brake Assist detects a risk of colli-
sion with the vehicle in front, it calculates the
braking force necessary to avoid a collision. If
you apply the brakes forcefully, adaptive Brake
Assist will automatically increase the braking
force to a level suitable for the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds above
4 mph (7 km/h). It uses radar sensor technology
to assess the traffic situation.
Up to a speed of approximately 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 a speed of approximately 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
®) are activated
simultaneously (Ypage 57).
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from loc king.
The br

akes will work normally again if:
Ryou release the brake pedal.
Rthere is no longer any danger of a collision.
Rno obstacle is detected in front of your vehi-
cle.
Adaptive Brake Assist is then deactivated.
Important safety notes
iObserve the "Important safety notes" sec-
tion for driving safety systems (Ypage 65).
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot 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.
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
Driving safety systems69
Safety
Z

Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause Brake Assist to intervene.
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.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-
tion (Ypage 65).
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 vehi-
cle 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" sec-
tion (Ypage 65).
ETS traction control is part of ESP
®. On vehicles
with 4MATIC, 4ETS is part of ESP®.
Traction control brakes the drive wheels indi-
vidually 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 transfer-
red to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP
®.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 65).
GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP®checked at a
qualified specialist workshop.
If the å ESP
®OFF warning lamp lights up
continuously, ESP®is deactivated.
If the ÷ ESP®warning lamp lights up contin-
uously, ESP®is not available due to a malfunc-
tion.
Observe the information on warning lamps
(
Ypage 259) and display messages which may
be shown in the instrument cluster
(
Ypage 228).
Only use wheels with the recommended tire
sizes. Only then will ESP
®function properly.
Characteristics of ESP®
General information
If the ÷ ESP®warning lamp goes out before

ESP®trailer stabilization
General information
If your vehicle/trailer combination begins to
swerve, ESP®assists you in this situation. ESP®
slows the vehicle down by braking and limiting
the engine output until the vehicle/trailer com-
bination has stabilized.
Important safety notes
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP
®can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
If your vehicle with trailer (vehicle/trailer com-
bination) begins to lurch, you can only stabilize
the vehicle/trailer combination by depressing
the brake firmly.
ESP
®trailer stabilization is active above speeds
of approximately 40 mph (65 km/h).
ESP
®trailer stabilization does not work if ESP®
is deactivated or malfunctioning.
Crosswind Assist
General information
Strong crosswind gusts can impair the ability of
your vehicle to drive straight ahead. The cross-
wind driving assistance function integrated in
ESP
®noticeably reduces these impairments.
ESP®intervenes automatically according to the
direction and intensity of the crosswinds affect-
ing your vehicle.
ESP
®intervenes with stabilizing braking to
assist you in keeping the vehicle in the lane.
Crosswind Assist is active at vehicle speeds
above 50 mph (80 km/h) when driving straight
ahead or cornering gently.
Important safety notes
Crosswind Assist does not work if ESP®is
switched off or deactivated because of a mal-
function.
EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 65).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (
Ypage 259) as well as display
messages (Ypage 230).
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 171) and hill start
assist (Ypage 136).
PRE-SAFE®Brake
General information
PRE-SAFE®Brake can help you to minimize the
risk of a collision with a vehicle ahead or a
pedestrian, 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.
iPay attention to the important safety notes
in the "Driving safety systems" section
(
Ypage 65).
PRE‑ SAFE
®Brake is only available in vehicles
with the Driving Assistance Plus package.
Driving safety systems73
Safety
Z

For PRE-SAFE®Brake to assist you when driving,
the radar sensor system and the camera system
must be switched on and be operational.
With the help of the radar sensor system and the
camera system, PRE-SAFE
®Brake can detect
obstacles that are in front of your vehicle for an
extended period of time.
In addition, pedestrians in the path of your vehi-
cle can be detected.
PRE-SAFE
®Brake detects pedestrians using
typical characteristics such as the body con-
tours and posture of a person standing upright.
iObserve the restrictions described in the
"Important safety notes" section
(
Ypage 74).
Important safety notes
GWARNING
PRE-SAFE
®Brake will initially brake your vehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you brake yourself. Even
after subsequent full application of the brakes
a collision cannot always be avoided, partic-
ularly when approaching at too high a speed.
There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so.
In the event of a partial application of the brakes,
the vehicle is braked with up to 50% of the full
braking pressure.
GWARNING
PRE-SAFE
®Brake cannot always clearly iden-
tify 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.
GWARNING
PRE-SAFE
®Brake cannot always clearly iden-
tify people, especially if they are moving. In
these cases, PRE-SAFE
®Brake cannot inter-
vene. There is a risk of an accident.
Always pay particular attention to the traffic

you must apply the brakes yourself.
GWARNING
PRE-SAFE
®Brake does not react:
Rto small people, e.g. children
Rto animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
As a result, PRE-SAFE
®Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
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.
