Mercedes-Benz GL-Class 2013 Owners Manual - Manual (Page 75)

If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
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 above speeds of
about 37 mph (60 km/h).
Trailer stabilization does not work if ESP
® is
deactivated because of a malfunction.
Crosswind driving assistance
Strong crosswinds can cause your vehicle to
deviate from a straight course. The crosswind
driving assistance function integrated into
ESP ® significantly reduces these effects.
ESP ® intervenes automatically according to
the direction and intensity of the crosswinds
affecting your vehicle.
When driving on straight roads or gentle
bends, your vehicle is kept safely on course
by a stabilizing brake intervention.
Crosswind driving assistance is active above
a vehicle speed of 80 km/h.
Crosswind driving assistance 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 66).
G WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps (
Y
page 323) as well as
display messages (
Y
page 289).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
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 211) and hill start assist
(
Y
page 166).
PRE-SAFE ® Brake
i Observe the "Important safety notes"
section (
Y
page 66).
PRE-SAFE ® Brake is only available in vehicles
with DISTRONIC PLUS.
If PRE-SAFE
® Brake is to aid you, the radar
sensor system must be:
R activated (
Y
page 281)
R operational
With the help of the radar sensor system,
PRE-SAFE ® Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
PRE-SAFE
® Brake can help you to minimize
the risk of a 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.
Starting at a speed of around
4 mph (7 km/h), this function warns you if
you very quickly approach a vehicle in front.
