ESP
®
(Electronic Stability Program)
General notes
i
Observe the "Important safety notes" sec-
tion (
Y
page 63).
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 63).
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
®
.

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: when towing
your vehicle with the front axle raised, it is
important that you observe the notes on ESP
®
(
Y
page 313).
ESP
®
is only deactivated if the å warning
lamp is lit continuously.
If the ÷ warning lamp and the å warn-
ing lamp are lit continuously, ESP
®
is not
available due to a malfunction.
Observe the information on warning lamps
(
Y
page 252) and display messages which
may be shown in the instrument cluster
(
Y
page 218).
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 auto-
matically active.
If ESP
®
intervenes, the ÷ ESP
®
warning
lamp flashes in the instrument cluster.
If ESP
®
intervenes:
X
Do not deactivate ESP
®
under any circum-
stances.
