Mercedes-Benz 2013 GLS Class - Manual (Page 74)

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
If you deactivate ESP ® :
R ESP ® no longer improves driving stability.
R
traction control is still activated.
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.
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.
Vehicles with ECO start/stop function: the
ECO start/stop function switches the engine
off automatically when the vehicle comes to
a stop. When pulling away again, the engine
starts automatically. ESP
® remains in its pre-
viously selected status. Example: if ESP ® was
deactivated before the engine was switched
off, ESP
® remains deactivated when the
engine is switched on again.
ESP ® trailer stabilisation
G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high centre 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/trailer combination begins to
lurch, you can only stabilise 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 stabi-
lised.
Trailer stabilisation is active above speeds of
about 65 km/h.
Trailer stabilisation does not work if ESP
® is
deactivated or disabled because of a mal-
function.
EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion ( Y page 67).
G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This increa-
ses 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 295) as well as dis-
play messages ( Y page 268).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (
Y page 201) and
hill start assist ( Y page 160).
