Control of the vehicle
Never coast with engine not
running (except during Autostop)
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,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 159.
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.
Control indicator c 3 106.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
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 and the cleaning process of the diesel particle filter may take
place more often.
