Driving and operating233conditions. 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 cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be
indicated by illumination of control
indicator j 3 98. Seek the
assistance of a workshop
immediately.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.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on page 3 261 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.
If control indicator Z flashes, the
permitted emission limits may be
exceeded. Lift your foot off the
accelerator until Z stops flashing and
is steadily illuminated. Contact a
workshop immediately.
Malfunction indicator light 3 98.
AdBlue
General information The selective catalytic reduction 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 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.
306Vehicle careCaution
Do not tow the vehicle from the
rear. The front towing eye must
only be used for towing and not
recovering a vehicle.
Switch on ignition to permit operation
of brake lights, horn and windscreen
wipers, and move the steering wheel
slightly to release the steering wheel
lock.
Switch off the air suspension system 3 230.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 252, otherwise the
vehicle may automatically brake during towing.
Move the selector lever to neutral.
Release the parking brake.
Caution
Vehicles with manual
transmission automated: If neutral cannot be selected, the vehiclemust only be towed with the drive
wheels raised off the ground.
The vehicle should always be
towed with the ignition switched
off.
Manual transmission automated
3 240.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust fumes
from the towing vehicle, switch on the air recirculation system 3 208 and
close the windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye
and refit the cover.
Towing another vehicle
Attach a tow rope – or better still a tow
rod – to the rear towing eye, never to
the rear axle and suspension units.
Caution
The rear towing eye must only be
used for towing and not recovering a vehicle.
