Mercedes-Benz M-Class 2012 Owners Manual - Manual (Page 67)

In this situation, ESP ® assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ® slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has
stabilized.
Trailer stabilization is active from a speed of
approximately 37 mph(60 km/h).
G WARNING
The system will not be able to assist when the
trailer jackknifes
R if the ESP ® has switched off due to a
malfunction
R on wet or icy roads
R on roads with slippery surface
R in sand or gravel
Trailers with a high center of gravity may tip
over before the system recognizes swaying of
the trailer.
Trailer stabilization does not work if ESP ® is
deactivated or disabled because of a
malfunction.
EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section (
Y
page 61).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
G WARNING
If EBD has malfunctioned, the braking system
remains available with full brake boosting
effect. However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident. You should therefore adapt your
driving style to the different handling
characteristics.
X Observe the notes on warning and indicator
lamps (
Y
page 272) as well as display
messages (

page 241).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
(
Y
page 179) and hill start assist
(
Y
page 142). For further information, see
Driving tips (
Y
page 159).
PRE-SAFE ® Brake
PRE-SAFE ® Brake is only available in vehicles
with DISTRONIC PLUS.
i Observe the "Important safety notes"
section (
Y
page 61).
PRE-SAFE ® Brake can help you to minimize
the risk of a frontal collision with a vehicle
ahead or reduce the effects of such a
collision. If PRE-SAFE ® Brake has detected a
risk of collision, you will be warned visually
and acoustically as well as by automatic
braking. PRE-SAFE ® Brake cannot prevent a
collision without your intervention.
At speeds above approximately
20 mph (30 km/h), this function warns you
when you are rapidly approaching the vehicle
in front. An intermittent warning tone will
then sound and the · distance warning
lamp in the instrument cluster will light up.
X Brake immediately in order to increase the
distance from the vehicle in front.

Take evasive action provided it is safe to do
