A warning message appears when

exhaust filter is full. Start cleaning

process as soon as possible.

A warning message also appears

when exhaust filter has reached the

maximum filling level. Start cleaning

process immediately to avoid

damage to the engine.

Automatic cleaning process

Engine exhaust

The exhaust filter system filters 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

9 Danger

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.

Activate self-cleaning process

Cleaning process is completed more

quickly at high engine speeds and

loads. Therefore, drive in lower gears

than normal, and use manual gear

selection on vehicles with automatic

transmission. Usage of electrical

consumers like air conditioning and

heated windows to increase engine

load supports cleaning process.

25 minutes. Typically it needs

between 7 and 12 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.

Avoid driving with an open load

compartment, otherwise exhaust

gases could enter the vehicle.

Exhaust filter

System requires cleaning

Under certain conditions, e.g. driving

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 a warning message in

the Driver Information Centre.

The exhaust filter is a particle filter for

diesel and petrol engines.

Caution

If possible, do not interrupt

cleaning process. Drive until

cleaning is completed to avoid the

need for service or repair by a

workshop.

162

Driving and operating

Vehicles with petrol engine

To activate cleaning process,

continue driving, keep engine speed

above 2500 rpm. Shift down if

necessary.

Drive dynamically at different engine

speeds. Use engine brake for

deceleration, if possible.

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.

Cleaning process not possible

If cleaning is not possible for any

reason, 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.

Keep on driving until self-cleaning

operation is complete and the display

message disappears.

Catalytic converter

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

The catalytic converter reduces the

amount of harmful substances in the

exhaust gases.

Vehicles with diesel engine

To activate cleaning process,

continue driving, keep engine speed

above 2000 rpm, ideally and

continuously around 2500 rpm. Shift

down if necessary.

Keep on driving until self-cleaning

operation is complete and the display

message disappears.

Caution

Fuel grades other than those listed

on pages 3 211, 3 278 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.

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.

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).

At an AdBlue range below 560 miles,

the following warning messages are

alternately displayed and cannot be

dismissed:
