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 may be a controlled
reduction in power steering assist and
vehicle speed is reduced.
Stop-start system 3 116.
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.
Driving downhill
Engage a gear when driving downhill
to ensure that sufficient brake
pressure is available.
114Driving and operatingSteeringIf 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.Caution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
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 diesel particle filter may take
place more often.
Diesel particle filter 3 120.
Autostop may be inhibited to allow for
charging of the vehicle battery.
Stop-start system 3 116.
Ignition switch positions Turn key:0:ignition off:
Some functions remain active
until key is removed or driver's
door is opened, provided the
ignition was on previously1:ignition on, steering wheel lock
released.
Control indicators illuminate and
most electrical functions are
operable.
Diesel engine is preheating.2:engine start: Release key after
starting procedure begins
120Driving and operatingEngine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle 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 15 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.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If the cleaning of the filter is required
and if previous driving conditions did
not enable automatic cleaning, it will
be indicated by control indicator %.
Depending on version, a warning
message may also appear in the
Driver Information Centre 3 90.
Control indicator % illuminates when
diesel particle filter is full. Start
cleaning process as soon as possible to avoid damage to the engine.
Cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Diesel particle filter
cleaning is then started.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Control indicator % extinguishes as
soon as the self-cleaning operation is
complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
124Driving and operatingSwitch off engine if stopping for a
lengthy period, e.g. in traffic jams.
Engine braking
Automatic mode
When driving downhill, the manual
transmission automated does not
shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect, select a lower gear in good time when
driving downhill.
Rocking the vehicle Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.Parking
Apply the parking brake. The most recently engaged gear (see
transmission display) remains
engaged.Caution
Do not leave the vehicle with the
transmission in position N.
When the ignition is switched on, a
warning chime will sound when the
vehicle is parked if the transmission is still in N.
When the ignition is switched off, the transmission no longer responds to
movement of the selector lever.
Manual mode If engine speed is too low, the
transmission automatically shifts to a
lower gear.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions. If engine
speed is too high, the transmission
only switches to a higher gear via
kickdown 3 124.
When gearshifting is recommended
to improve fuel economy, control
indicator [ or Ò illuminates in the
Driver Information Centre 3 85.
Electronic driving programmes
Eco mode E
When automatic mode is engaged,
the Eco mode can be selected to
reduce fuel consumption.
134Driving and operatingFuel
Fuel for petrol engines Only use unleaded fuel that complies
with European standard EN 228 or equivalent.
The engine is capable of running with fuel that contains up to 10% ethanol
(e.g. named E10).
Use fuel with the recommended
octane rating. A lower octane rating
can reduce engine power and torque
and slightly increases fuel
consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to EN 228 or equivalent can lead todeposits or engine damage.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled combustion and engine damage.
The engine-specific requirements
regarding octane rating are given in
the engine data overview 3 183. A
country-specific label at the fuel filler
flap can supersede the requirement.
Fuel for diesel engines Only use diesel fuel that complies
with EN 590 and which has a sulphur
concentration of max. 10 ppm.
Fuels with a biodiesel (compliant with
EN 14214) content of max. 7% by
volume may be used (e.g. named
B7).
If travelling in countries outside the
European Union occasional use of Euro-Diesel fuel with a sulphur
concentration below 50 ppm is
possible.Caution
Frequent usage of diesel fuel containing more than 15 ppm
sulphur will cause severe engine
damage.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
