All systems function during an
Autostop.
Stop-start system 3 136.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.Use only floor mats, which fit properly and are fixed by the retainers on the
driver side.
Steering If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system. Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher.
Additionally, the cleaning process of
the exhaust filter may take place more
often.
