Operation Manual

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 does not flash. 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 cutting
action for better traction on loose surfaces.
R
Traction control is still activated.
R
COLLISION PREVENTION ASSIST is no longer
available; nor is it activated if you brake firmly
with assistance from ESP
®
.
R
PRE-SAFE
®
is no longer available, nor is it
activated if you brake firmly and ESP
®
inter-
venes.
R
PRE-SAFE
®
Brake is no longer available, it is
also not activated if you brake firmly and ESP
®
intervenes.
R
ESP
®
still provides support when you brake
firmly.
ESP
®
trailer stabilization
General information
ESP
®
trailer stabilization is not available in
Mercedes-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 com-
bination 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 com-
bination) begins to lurch, you can only stabilize
the vehicle/trailer combination by depressing
the brake firmly.
ESP
®
trailer stabilization is active above speeds
of about 65 km/h.
ESP
®
trailer stabilization does not work if ESP
®
is deactivated or disabled because of a malfunc-
tion.
EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes
i
Observe the "Important safety notes" sec-
tion for driving safety systems (
Y page 64).
G
WARNING
If EBD is malfunctioning, the rear wheels can
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 spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (
Y page 238) as well as display
messages (
Y page 214).
ADAPTIVE BRAKE
i
Observe the "Important safety notes" sec-
tion (
Y page 64).
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 164) and hill start
assist (
Y page 130).
