Braking
X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking
situation is over.
X To make a full brake application:
depress the brake pedal with full force.
If AB Sintervenes when braking, you will feel
a pulsing in the brake pedal.
The pulsating brake pedal can be an
indicatio nofhazardous road conditions, and
functions as a reminder to take extra care
while driving. BAS (Brake Assist System)
i Observe the "Important safety notes"
sectio n(Ypage 59). G
WARNING
If BASi s 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.
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
The brakes will function as usual once you
release the brake pedal.B AS is deactivated.BAS PLUS (Brake Assist System Plus)
i Observe the "Important safety notes"
sectio n(Ypage 59).
BASP LUS is only available in vehicles
equipped with DISTRONIC PLUS.
BAS PLUS provides braking assistance in
hazardous situations at speeds greater than 20 mph (30 km/h) and uses radar sensor
technology to assess the traffic situation.
With the help of the radars
ensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
At speeds up to 40 mph (70 km/h), BAS PLUS
may also detec tstationary obstacles, for
example, stopped or parked vehicles.
To prevent a front-end collision, BAS PLUS
calculates the brake force necessary if:
R you approach an obstacle, and
R BAS PLU Shas detected arisk of collision
Should you apply the brakes forcefully, BAS
PLUS will automatically increase the braking
force to a level suitable for the traffic
conditions.
If BAS PLUS demands particularly high
braking force, preventative passenger
protection measures (PRE-SAFE ®
) are
activated 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
function as usual, if:
R you release the brake pedal.
R there is no longer any dange rofarear-end
collision.
R no obstacle is detected in front of your
vehicle.
For BAS PLUS to assist you when driving, the
rada rsensor system must be:
R switched on (Y page 206)
R be operational (Y page 229)
If the radar sensor system is malfunctioning,
BASP LUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS. G
WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations. BAS 60
Driving safety systemsSafety

PLUS cannot intervene in these cases. There
is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example in parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in frontonadifferent line
relative to the center of your vehicle G
WARNING
BAS PLUS does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As aresult, BAS PLUS may not 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.
Following damage to the fron tend of the
vehicle, have the configuratio nand operation
of the rada rsensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the fron tofthe vehicle.

Important safety notes i
Observe the "Important safety notes"
section (Y page 59). G
WARNING
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.
! When testing the electric parking brake
on a braking dynamometer, switch off the
ignition .Application of the brakes by
ESP ®
may otherwise destroy the brake
system.
When towing the vehicle with the rear axle
raised, observe the notes on
ESP ®
(Y page 302).
ESP ®
is deactivated if the 0014warning lamp
in the instrument cluster lights up
continuously when the engin eis running.
If the 000C warning lamp and the 0014
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 246) and displaym essages which
may be shown in the instrument cluster
(Y page 212).
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. Driving safet

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
(Y page 177) and hill start assist
(Y page 139). PRE-SAFE
®
Brake
i Observe the "Importan tsafety notes"
sectio n(Ypage 59).
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
PRE-SAFE ®
Brake can help you to minimize
the risk of a collision with a vehicle ahead or
reduce the effects of such a collision. If PRE-
SAFE ®
Brake detects a risk of collision, you
will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE ®
Brake cannot preven tacollision withoutyour
intervention.
Starting at a speed of around
20 mph (30 km/h), this function warns you if
you very quickly approach a vehicle in front.
An intermittent warning tone will then sound
and the 000Cdistance warning lamp will light
up in the instrument cluster.
X Brake immediately in orde rto increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
From a speed of approximately
20 mph (30 km/h), if the driver and front
passenger have fastened their seat belts,
PRE-SAFE ®
Brake can brake the vehicle
automatically at speeds up to approximately
124 mph (200 km/h).
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ®
Brake. You can prevent the intervention of the PRE-
SAFE
®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you maneuver to avoid the obstacle.
R there is no longer any danger of a rear-end
collision.
R there is no longer an obstacle detected in
front of your vehicle.
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.
At speeds up to approximately
40 mph (70 km/h), PRE-SAFE ®
Brake can
also detect stationary obstacles such as
stopped or parked vehicles.
If you approach an obstacle and PRE-SAFE ®
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If
you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If there is an increased risk
of collision, preventative passenger
protection measures (PRE-SAFE ®
) are
activated (Y page 50).
If a risk of collision remains and you do not
brake, take evasive action or significantly
accelerate, automatic braking may be
performed up to a level of automatic
emergency braking. Automatic emergency
braking is not performed until immediately
prior to an accident that can no longer be
avoided. G
WARNING
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 emergenc ybraking cannot prevent
a collision. There is a risk of an accident. Driving safety systems

R to crossing traffic
R when 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 order to maintain the appropriate distance
to the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.

To activate/deactivate: activate or
deactivate PRE-SAFE ®
Brake in the on-
board computer (Y page 202).
When PRE-SAFE ®
Brake is activated, the
0001 symbol appears in the multifunction
display as long as the HOLD function is
deactivated (Y page 177). On vehicles with
Parking Guidance, the 0001symbol is
displayed when position Pis engaged or
you are driving faster than 22 mph
(35 km/h).
For PRE-SAFE ®
Brake to assist you when
driving, the radar senso rsystem mus tbe
switched on (Y page 206) and be

WARNING
The DISTRONIC PLUS cannot take weather
conditions into account. Switch off the
DISTRONIC PLUS or do not switch it on if:
R roads are slippery or covered with snow or
ice. The wheels could lose traction while
braking or accelerating, and the vehicle
could skid.
R the DISTRONIC PLUS system sensor covers
are dirty or visibility is diminished due to
snow, rain or fog, for example. The distance
control system functionality could be
impaired.
Always pay attention to surrounding traffic
conditions even while the DISTRONIC PLUS is
switched on. Otherwise, you may not be able
to recognize dangerous situations until it is
too late. This could caus eanaccident in which
you and/or others could be injured. G
WARNING
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particula rpreset speed. G
WARNING
Your undivided attention to street and traffic
conditions is necessary at all times whether
DISTRONIC PLUS is active or not.
The use of DISTRONIC PLUS can be
dangerous on winding roads or in heavy traffic
because conditions do not allow safe driving
at a constant speed.
DISTRONIC PLUS does not react to stationary
objects on the road (for example, a vehicle
stopped in traffic or an abandoned vehicle).
DISTRONIC PLUS likewise does not react to
oncoming vehicles. Deactivate DISTRONIC PLUS:
R
when changing to the right lane, if the
vehicles in the left lane are driving slower
R when driving into a filter lane or an
expressway exit
R in comple xdriving situations, for example
in construction sites on an expressway
In these situations DISTRONIC PLUS will
maintai nthe set speed if it is not deactivated.
DISTRONIC PLUS is intended only for
maintaining a set speed and a set distance
from the objects moving in front of the
vehicle. G
WARNING
An intermittent warning sounds and the
distance warning lamp 000Cin the instrument
cluster is illuminated if the DISTRONIC PLUS
system calculates that the distance to the
vehicle ahead and your vehicle's current
speed indicate that the DISTRONIC PLUS will
not be capable of slowing the vehicle
sufficiently to maintain the preset following
distance, which creates a danger of a
collision.
Immediately brake the vehicle to increase
your distance to the preceding vehicle. The
warning sound is intended as a final caution
in which you should intercede with your own
braking inputs to avoid a potentially
dangerous situation. Do not wait for the
operation of the warning signal to intercede
with your own braking. This will result in
potentially dangerous emergency braking
which will not always result in an impact being
avoided.
Tailgating increases the risk of an accident. G
WARNING
DISTRONIC PLUS brakes your vehicle with a
maximum deceleration of 13 ft/s 2
(4 m/s 2
).
This corresponds to approximately 40% of
your vehicle's maximum braking force.
To avoid a collision, you must apply the brakes
yourself. DISTRONIC PLUS brakes the vehicle Driving systems

jus
tenough to restore the preset speed or the
preset distance to the vehicle in front. G
WARNING
If you do not receive visual or acoustic
warning signals during a critical traffic
situation, DISTRONIC PLU Shas either not
recognized the collision risk, has been
deactivated or is malfunctioning.
Remember, whether or no tDISTRONIC PLUS
is operating, it is ultimately always the drivers
responsibility to apply the brakes in order to
control the vehicle and avoid a collision.
General notes i
DISTRONIC PLUS is not available on AMG
vehicles.
DISTRONIC PLUS regulates the speed and
automatically helps you maintain the
distance to the vehicle detected in front.
DISTRONIC PLUS brakes automatically so
that the set speed is not exceeded.
On long and steep downhill gradients,
especially if the vehicle is laden, you must
select shift range 1,2or 3in good time
(Y page 149). By doing so, you will make use
of the braking effect of the engine, which
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
If a slower-moving vehicle is detected in front,
DISTRONIC PLUS brakes your vehicle. It
maintains the preset distance to the vehicle
in front.
If you want DISTRONIC PLUS to assist you,
the radars ensor system must be activated
(Y page 206) and operational.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and120 mph (Canada:
200 km/h). If a vehicle is driving in front of
you, it operates in the speed range between
0 mph (0 km/h) and 120 mph (Canada:
200 km/h). Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.
