The air conditioning system cools and
dehumidifies (dries) when outside
temperature is above a specific level. Therefore condensation may form
and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
When the cooling system is switched
off, no engine restart will be
requested by the climate control
system during an Autostop.
Exception: defrost system is activated and outside temperature above 0 °C
requests a restart.

The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.
Automatic air recirculation
An air humidity sensor switches
automatically to external air if internal air humidity is too high.

operate the engine briefly at a low load or run in neutral for

168Driving and operatingCaution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the need for service or repair by a
workshop.
Cleaning process not possible
If cleaning is not possible for anyreasons, control indicator Z
illuminates and a warning message
appears in the Driver Information
Centre. Engine power may be
reduced. Seek the assistance of a
workshop immediately.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 220, 3 288 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.9Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.

Driving and operating169Caution
Avoid contact of the paintwork withAdBlue.
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. two litres per 600 miles, but
can also be higher depending on
driving behaviour (e.g. high load or
towing).
AdBlue tank
At a remaining volume of approx.
five litres, there is a liquid level switch. Warning messages are displayed
only below that threshold. Tank
volume 3 295.
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.
The first possible warning is AdBlue
Range: 1500 mi .
This warning will show up once briefly with the calculated range. Driving is
possible without any restrictions.
The next warning level is entered with
a range below 1090 miles. The
message with the current range will
always be displayed when ignition is
switched on and needs to be
confirmed 3 115 . Refill AdBlue before
entering the next warning level.
At an AdBlue range below 560 miles,
the following warning messages are
alternately displayed and cannot be
dismissed:
● AdBlue Low Refill Now
● Engine Restart Prevented in 560
miles .
Additionally, control indicator Y
flashes continuously.Notice
In case of high AdBlue consumption,
the Driver Information Centre may
display this warning without the
previous warning stages.
The last warning level is entered
when the AdBlue tank is empty.
Restart of the engine is not possible.
The following warning messages are
alternately displayed and cannot be
dismissed:
● AdBlue Empty Refill Now
● Engine Will Not Restart .
Additionally, control indicator Y
flashes continuously.
With active prevention of an engine
start, the following message will be
displayed:
Refill AdBlue To Start Vehicle .
The tank must be refilled completely
with AdBlue, otherwise restarting of
the engine is not possible.

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
