As soon as the traffic conditions

permit, regenerate the filter by driving

at a vehicle speed of at least 40 mph

until the control indicator

extinguishes.

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.

Notice

Caution

On a new vehicle, the first exhaust

filter regeneration operations may

be accompanied by a burning smell,

which is normal. Following

Fuel grades other than those listed

on pages 3 195, 3 247 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.

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.

Avoid driving with an open load

compartment, otherwise exhaust

gases could enter the vehicle.

Cleaning process not possible

Exhaust filter

Automatic cleaning process

The exhaust filter system filters soot

particles out of the exhaust gases.

The start of saturation of the exhaust

filter is indicated by the temporary

illumination of t or C,

accompanied by a message in the

Driver Information Centre.

If t 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.

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.

Driving and operating

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 warning level is entered

when the estimated AdBlue range

is between 1500 miles and

500 miles.

131

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

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.

In some circumstances below the

mentioned temperature, an error

message appears in the Driver

Information Centre. In this event, park

the vehicle in a space with a higher

ambient temperature until AdBlue is

liquefied.

When switching on the ignition,

this warning will show up once

briefly with the calculated range.

Additionally, control indicator

B will illuminate and a chime

will sound. Driving is possible

without any restrictions.

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.

2. The next warning level is entered

when the estimated AdBlue range

is below 500 miles. The message

with the current range will always

be displayed when ignition is

switched on. Additionally, control

indicator B will flash and a

chime will sound. Refill AdBlue

before entering the next warning

level.

9 Warning

Notice

Avoid contact of your eyes or skin

with AdBlue.

In case of eye or skin contact,

rinse off with water.

Frozen and again liquefied AdBlue is

usable without quality loss.

The typical AdBlue consumption is

approx. 2 l per 600 miles, but can also

be higher depending on driving

behaviour (e.g. high load or towing).

Driving and operating

3. The next warning level is entered

with a range below 60 miles. The

message with the current range

will always be displayed when

ignition is switched on.

The messages and the restrictions

are a legal requirement. The warning

messages are accompanied by the

control indicators u, C and W.

Additionally, a chime will sound.

Follow the instructions of the warning

messages. If starting is prevented,

seek the assistance of a workshop.

Notice

Whenever a filling pump with a

nozzle for passenger cars is not

available at a filling station, use only

AdBlue bottles or canisters with a

sealed refill adapter for refilling, to

prevent splashback and overspill,

and in order to ensure that the fumes

from the AdBlue tank are captured

and do not emerge.

Additionally, control indicator

B will flash and a chime will

sound. Refill AdBlue as soon as

possible before the AdBlue tank is

completely empty. Otherwise, a

restart of the engine will not be

possible.

Refilling AdBlue

Caution

Since AdBlue has a limited

durability, check the date of expiry

before refilling.

4. The last warning level is entered

when the AdBlue tank is empty.

Restart of the engine is not

possible.

Only use AdBlue that complies

with European standards

DIN 70 070 and ISO 22241-1.

Do not use additives.

Do not dilute AdBlue.

Otherwise the selective catalytic

reduction system could be

damaged.

Notice

Refill the AdBlue tank to a level of at

least 10 l, to ensure that the new

AdBlue level is being detected.

A message appears in the Driver

Information Centre. Additionally,

control indicator B will flash

and a chime will sound.

Refill the AdBlue tank completely,

otherwise restarting of the engine

is not possible.

In case AdBlue refill is not

successfully detected:

1. Continuously drive the vehicle

for ten minutes making sure that

vehicle speed is always higher

than 12 mph.

2. If AdBlue refill is detected

successfully, AdBlue supply-

driven warnings or limitations will

disappear.

The AdBlue tank should be filled

completely. This must be done if the

warning message regarding

prevention of an engine restart is

already displayed.

High emission warnings

In the event of a fault with the

emissions control system, different

messages are displayed in the Driver

Information Centre.
