Mercedes-Benz M-Class 2015 Owners Manual - Manual (Page 76)

It may be best to deactivate ESP ® in the fol-
lowing situations:
R when using snow chains
R in deep snow
R
on sand or gravel
i Activate ESP ® as soon as the situations
described above no longer apply. ESP ® will
otherwise not be able to stabilize the vehi-
cle if the vehicle starts to skid or a wheel
starts to spin.
! Avoid spinning the driven wheels for an
extended period with ESP ® deactivated.
You could otherwise damage the drivetrain.

Characteristics when ESP ® is deactivated
If ESP ® is deactivated and one or more wheels
start to spin, the ÷ ESP ® warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP ® will not stabilize the vehicle.
If you deactivate ESP ® :
R ESP ® no longer improves driving stability.
R engine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a cut-
ting action for better traction on loose sur-
faces.
R traction control is still activated.
R ESP ® still provides support when you
brake.
Off-road ESP ® (vehicles with Off-Road
Engineering package)
An ESP ® system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated (
Y
page 251).
Off-road ESP ® intervenes with a delay if there
is oversteering or understeering, thus improv-
ing traction.
ESP ® trailer stabilization
General information
ESP
® trailer stabilization is not available in
AMG vehicles.
If your vehicle/trailer combination begins to
swerve, ESP ® assists you in this situation.
ESP ® slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilized.
Important safety notes
G WARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP
® can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
Trailer stabilisation is active above speeds of
about 37 mph (60 km/h).
