Control indicator Ø illuminates in the
instrument cluster and a
corresponding message appears in
the Driver Information Centre 3 104.
When vehicle speed reaches 30 mph, the system switches
automatically from Enhanced
Traction function to ESP® Plus
operation. Control indicator Ø
extinguishes in the instrument cluster.
ESP® Plus
is reactivated by pressing
Ø again. Control indicator Ø
extinguishes.
ESP® Plus
is also reactivated the next
time the ignition is switched on.
Engine Drag Torque Control
The engine drag torque control
system is an integral feature of
ESP® Plus
. When downshifting under
slippery road conditions, the engine
speed and torque increases to help
prevent locking of the drive wheels
during sudden deceleration.
Fault
If the system detects a fault, control indicator b 3 101 illuminates together
with j 3 99 in the instrument cluster
and a corresponding message
appears in the Driver Information
Centre 3 104.
The Electronic Stability Program
(ESP® Plus
) is not operational. Have
the cause of the fault remedied by a
workshop.
Vehicle messages 3 105.
Limited-slip rear axle
Rear-wheel drive vehicles may be
equipped with an automatic locking
rear differential which automatically
controls the torque transmitted toeach rear wheel, enhancing traction
in the event of soft ground, mud or
snow-covered road surfaces.9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
When vehicle speed reaches
20 mph, or once the rear wheels
return to surfaces with normal grip,
e.g. paved roads, the system
automatically deactivates,
sometimes accompanied by a noise
(with no consequence to vehicle
behaviour).
The system can also be deactivated
manually once normal grip conditions have resumed by briefly releasing the
accelerator.
