4ETS (Electronic Traction System)
G WARNING
Observe "Important safety notes"
(
Y page 53).
Traction control is part of ESP ® .
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull away and accelerate on slippery surfaces,
for example if the road surface is slippery on
one side. In addition, more drive torque is
transferred to the wheel or wheels with
traction.
Traction control remains active if you
deactivate ESP
® .
Traction control is no longer active at speeds
above approximately 37 mph (60 km/h).
Deactivating/activating ESP ®
G
WARNING
The ESP ® should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
ESP ® is activated automatically when the
engine is started.
It may be best to deactivate ESP
® in the
following situations:
R when using snow chains
R
in deep snow
R
on sand or gravel
G WARNING
Switch on ESP ® immediately if one of the
previously stated conditions is no longer met.
Otherwise, ESP
® cannot stabilize the vehicle
if it begins to lurch or when a wheel spins.
If you deactivate ESP ® :
R ESP ® no longer improves driving stability.
R
the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R
traction control is still activated.
R ESP ® still provides support when you
brake.
R and drive over 37 mph (60 km/h), ESP ®
intervenes when the grip limit of a wheel is
reached, even if it is deactivated.
If ESP ® is deactivated and one or more wheels
start to spin, the ÷ warning lamp in the
instrument cluster flashes. In such situations,
ESP
® will not stabilize the vehicle.
If you have deactivated ESP ® , it is
automatically reactivated if you exceed a
speed of 37 mph (60 km/h) or a certain
lateral acceleration.
X To deactivate: press button : until the
å warning lamp lights up in the
instrument cluster.
G
WARNING
When the å ESP ® OFF warning lamp is lit,
ESP ® is deactivated.
If the ÷ ESP ® warning lamp and the
å ESP ® OFF warning lamp remain lit,
ESP ® is not available due to a malfunction.
When ESP ® is deactivated or not operational,
vehicle stability in standard driving
maneuvers is reduced.
Adapt your speed and driving to the prevailing
road conditions and to the non-operating
status of the ESP
® .
