ESP ® (Electronic Stability Program)
General notes
i Observe the "Important safety notes" sec-
tion (
Y
page 71).
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)
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 ® .

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 with 4MATIC: switch off the igni-
tion when the parking brake is being tested
on a brake dynamometer.
Application of the brakes by ESP ® may oth-
erwise destroy the brake system.
! Vehicles with 4MATIC: function or per-
formance tests may only be carried out on
a 2-axle dynamometer. Before you operate
the vehicle on such a dynamometer, please
consult a qualified workshop. You could
otherwise damage the drive train or the
brake system.
