Driving and operating139Driving hints
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 3 141.
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 is displayed 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's 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 88.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 exhaust filter may take place more
often. Autostop may be inhibited to
allow for charging the battery.
Exhaust filter 3 144.
Driving and operating145Automatic cleaning processThe exhaust filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Typically it
needs between seven and twelve
minutes. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process is normal.System requires cleaning
Under certain conditions, e.g. driving
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be
indicated by illumination of % and a
warning message in the Driver
Information Centre.
% illuminates along with a warning
message when exhaust filter is full.
Start cleaning process as soon as
possible.
% flashes along with a warning
message when exhaust filter has
reached the maximum filling level.
Start cleaning process immediately to
avoid damage to the engine.
Activate self-cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Exhaust filter cleaning is
then started.
Cleaning process is completed more quickly at high engine speeds and
loads.
Control indicator % extinguishes as
soon as the self-cleaning operation is complete. Keep on driving until self-
cleaning operation is complete.Caution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the
need for service or repair by a
workshop.
