Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited.
■ The stop-start system is not manually deactivated
■ the bonnet is fully closed
■ the driver's door is closed or the driver's seat belt is fastened
■ the vehicle battery is sufficiently charged and in good condition
■ the engine is warmed up
■ the engine coolant temperature is not too high
■ the ambient temperature is not too low
■ the defrosting function is not activated
■ the climate control system does not
inhibit an Autostop
■ the brake vacuum is sufficient
■ the vehicle has moved since the last Autostop
■ the diesel particle filter self- cleaning function is in progress
An Autostop may be less available as
the ambient temperature approaches
freezing point.Certain settings of the climate control system may inhibit an Autostop. See
Climate control chapter for further
information 3 94.
Immediately after motorway driving
an Autostop may be inhibited.
Autostop may also be inhibited
temporarily if the vehicle battery has
been recharged by an external
source.

Traction Control system
The Traction control system (TC) is a
component part of the Electronic
stability program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
ignition is switched on and control
indicator v extinguishes in the
instrument cluster.
When TC is active v flashes.
