danger to yourself and others.
All systems function during an
Autostop.

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.
