130Driving and operatingAs soon as the traffic conditions
permit, regenerate the filter by driving at a vehicle speed of at least 60 km/h
until the control indicator
extinguishes.
Note
On a new vehicle, the first exhaust
filter regeneration operations may
be accompanied by a burning smell, which is normal. Following
prolonged operation of the vehicle at
very low speed or at idle, water
vapour can be emitted at the
exhaust on acceleration. This does
not affect the behaviour of the
vehicle or the environment.
Cleaning process not possible
If % or C stays on, accompanied
by an audible signal and a message,
this indicates that the exhaust filter
additive level is too low.
The reservoir must be topped-up
without delay. Seek the assistance of
a workshop.Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 166, 3 226 could
damage the catalytic converter or
electronic components.
Unburnt fuel will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
AdBlue
General information
The selective catalytic reduction
(BlueInjection) is a method to
substantially reduce the nitrogen
oxides in the exhaust emission. This
is achieved by injecting a Diesel
Exhaust Fluid (DEF) into the exhaust
system. The ammonia released by
the fluid reacts with nitrous gases
(NO x) from the exhaust and turns it
into nitrogen and water.
The designation of this fluid is
AdBlue ®
. It is a non-toxic, non-
flammable, colourless and odourless
fluid which consists of 32% urea and
68% water.9 Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Driving and operating135Manual mode
Move selector lever out of position D
towards the left in position M.
Tap selector lever towards + to shift
to a higher gear.
Tap the selector lever towards - to
shift to a lower gear.
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed. This can
cause a message in the Driver
Information Centre.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shifting 3 84.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● Special programmes automatically adapt the shifting
points when driving up inclines or
down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission control
enables the driver to select
manually first, second or third gear for starting off.Kickdown
Pressing down the accelerator pedal
beyond the kickdown detent will lead to maximum acceleration
independent of selected driving
mode. The transmission shifts to a
lower gear depending on engine speed.
Fault
In the event of a fault a message is
displayed in the Driver Information
Centre.
Vehicle messages 3 94.
Electronic transmission control
enables only third gear. The
transmission no longer shifts
automatically.
Do not drive faster than 100 km/h.
Have the cause of the fault remedied by a workshop.
Interruption of power supply In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P
position.
