ESP
®is activated automatically when the engine
is started.
iVehicles with the ECO start/stop func-
tion: the ECO start/stop function automati-
cally switches the engine off when the vehicle comes to a stop. The engine starts automati-
cally when the driver wants to pull away again.
ESP
®remains in its previously selected sta-
tus. For example, if ESP®was deactivated
before the engine was switched off, ESP®
remains deactivated when the engine is
switched on again.
It may be best to deactivate ESP
®in the follow-
ing situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
If you deactivate ESP®:
RESP®no longer improves driving stability.
Rthe engine's torque is no longer limited and
the drive wheels can spin. The spinning of the wheels results in a cutting action, which pro-
vides better grip.
Rtraction control is still activated.
RESP®still provides support when you brake.
Rand are driving at above 37 mph (60 km/h)
(on AMG vehicles above 62 mph (100 km/h)),
ESP
®still intervenes when one wheel reaches
its grip limit even though it is deactivated.
iIf ESP®is deactivated and one or more
wheels start to spin, the ÷warning lamp in the instrument cluster flashes. In such situa-
tions, ESP
®will not stabilize the vehicle.
iIf ESP®is deactivated, it is reactivated auto-
matically if you are driving at above 37 mph
(60 km/h) (on AMG vehicles above 62 mph
(100 km/h)) or you exceed a certain lateral
acceleration.
Trailer stabilization
GWARNING
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.
Trailer stabilization does not work if ESP
®is
deactivated because of a malfunction.
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.
In this situation, ESP
®assists you and can
detect if the vehicle/trailer combination begins
to lurch. ESP
®slows the vehicle down by brak-
ing and limiting the engine output until the vehi-
cle/trailer combination has stabilized.
Trailer stabilization is active above speeds of
about 37 mph (60 km/h).
EBD (electronic brake force distribu-
tion)
i
Observe the "Important safety notes" sec-
tion (Ypage 55).
GWARNING
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.
