Mercedes-Benz S-Coupe 2015 - Manual (Page 73)

The brakes will work normally again if:
R you release the brake pedal.
R there is no longer any danger of a collision.
R no obstacle is detected in front of your
vehicle.
Adaptive Brake Assist is then deactivated.
If adaptive Brake Assist demands particularly
high braking force, preventative passenger
protection measures (PRE-SAFE ® ) are activa-
ted simultaneously.
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
stationary obstacles.
ESP ® (Electronic Stability Program)
General notes
i Observe the "Important safety notes" sec-
tion (
Y
page 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 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)
i Observe the "Important safety notes" sec-
tion (
Y
page 65).
ETS traction control is part of ESP ® . On vehi-
cles 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 trans-
ferred to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP ® .
Important safety notes
G WARNING
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.
Vehicles without 4MATIC: observe the notes
on ESP ® (
Y
page 350) when towing the vehi-
cle with a raised rear axle.
ESP
® is only deactivated if the å warning
lamp is lit continuously.
If the ÷ warning lamp lights up continu-
ously, ESP ® is not available due to a malfunc-
tion.
Observe the information on warning lamps
(
Y
page 283) and display messages which
may be shown in the instrument cluster
(
Y
page 247).
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
beginning the journey, ESP ® is automatically
active.
If ESP
® intervenes, the ÷ ESP ® warning
lamp flashes in the instrument cluster.
