Control of the vehicle Never coast with engine not
running
Many systems will not function in this situation (e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others.
All systems function during an
Autostop.
Stop-start system 3 126.
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 on the Uplevel-
Display.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
124Driving and operatingUse 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.
Control indicator c 3 85.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.
Autostop may be inhibited to allow for
charging the vehicle battery.Ignition switch positions0:ignition off1:steering wheel lock released,
