X
To deactivate: press button : until the
å ESP ®
OFF warning lamp lights up in
the instrument cluster.
The ÷OFF message appears in the
multifunction display.
Deactivate ESP ®
when driving on
designated roads when the vehicle's own
oversteering and understeering
characteristics are
desired. Driving without
ESP ®
requires an extremely qualified and
experienced driver who is able to cope with
these critical driving conditions.
X To activate: briefly press button :.
The å ESP ®
OFF warning lamp in the
instrument cluster goes out. The ÷ON
message appears in the multifunction
display.
ESP ®
is activated automatically when the
engine is started.
If ESP ®


is deactivated and one or more wheels
start to spin, the ÷ ESP®
warning lamp in
the instrument cluster does not flash. In such
situations, ESP ®
will not stabilize the vehicle.
It may be best to deactivate ESP ®
in the
following situations:
R when using snow chains
R in deep snow
R on sand or gravel
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R traction control is still activated. R
PRE-SAFE ®
is no longer available, nor is it
activated if you brake firmly and ESP ®
intervenes.
R PRE-SAFE ®
Brake is no longer available, it
is also

not activated if you brake firmly and
ESP ®
intervenes.
R ESP ®
still provides support when you brake
firmly.
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction.
Vehicles with ECO start/stop function: the
ECO start/stop function switches the engine
off automatically when the vehicle comes to
a stop. The engine starts automatically when
the driver wants to pull away again. ESP ®
remains in its previously selected status.
Example: if ESP ®
was deactivated before the
engine was switched off, ESP ®
remains
deactivated when the engine is switched on
again. EBD (Electronic Brake-force
Distribution)
G
WARNING
If EBD has malfunctioned, the rear wheels can
still 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
specialist workshop.
Observe information regarding indicator and
warning lamps ( Y page 257) as well as
display messages ( Y page 226).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. 62
Driving safety systems
Safety

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. G
WARNING
PRE-SAFE ®
Brake cannot always clearly
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R not 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 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 front on a different line
relative to the center of your vehicle G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
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.
X To activate/deactivate: activate or
deactivate PRE-SAFE ®
Brake in the on-
board computer ( Y page 214).
When PRE-SAFE ®
Brake is activated, the
Ä symbol appears in multifunction
display, as long as the HOLD function is
deactivated (Y page

176). On vehicles with
Active Parking Assist, the Ä symbol is
displayed when P is engaged or you are
driving faster than 22 mph (35 km/h).
For PRE-SAFE ®
Brake to assist you when
driving, the radar sensor system must be
switched on (Y page 218) and be
operational.
Following damage to the front end of the
vehicle, have

the configuration and operation
of the radar sensors 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.
