154Driving and operatingCatalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 205, 3 262 could
damage the catalytic converter or
electronic components.
Unburnt petrol 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.
Caution
Avoid contact of the paintwork with AdBlue.
In case of contact, rinse off with water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
The typical AdBlue consumption is
approx. 0.85 l per 1000 km, but can
also be higher depending on driving
behaviour (e.g. high load or towing).
Level warnings
Depending on the calculated range of
AdBlue, different messages are
displayed in the Driver Information
Centre. The messages and the
restrictions are a legal requirement.
1. The first possible warning is Top
up emissions additive: Starting
prevented in 2400 km .
Driving and operating159
Press button M.
Pull steering wheel paddles to select
gears manually.
Pull right paddle + to shift to a higher
gear.
Pull left paddle - to shift to a lower
gear.
Multiple pulls allow gears to be
skipped.
The selected gear is indicated in the
instrument cluster.
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 shift indication
The symbol R or S with a number
beside it is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.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.
