switched off automatically if the

vehicle comes to a standstill within a

certain time.

9 Danger

For PHEV, make sure READY is

not illuminated in the Driver

Information Centre.

Lock the vehicle.

Activate the anti-theft alarm

system.

temperatures it may be necessary to

park the vehicle without applied

parking brake. Make sure to park the

vehicle on a level surface.

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.

Avoid driving with an open load

compartment, otherwise exhaust

gases could enter the vehicle.

●

Caution

After running at high engine

speeds or with high engine loads,

operate the engine briefly at a low

load or run in neutral for

approx. 30 seconds before

switching off, in order to protect

the turbocharger.

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 % or C,

accompanied by a message in the

Driver Information Centre.

Driving and operating

As soon as the traffic conditions

permit, regenerate the filter by driving

at a vehicle speed of at least 60 km/h

until the control indicator

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.

Note

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 3 253, 3 310 could

damage the catalytic converter or

electronic components.

Unburnt petrol will overheat and

damage the catalytic converter.

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.

Cleaning process not possible

If % 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.

9 Warning

Avoid contact of your eyes or skin

with AdBlue.

In case of eye or skin contact,

rinse off with water.

When driving, the message is

displayed every 30 seconds until

the additive tank has been

topped-up.

AdBlue freezes at a temperature of

approx. -11 °C. As the vehicle is

equipped with an AdBlue preheater,

the emissions reduction at low

temperatures is ensured. The AdBlue

preheater 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

High emission warnings

In the event of a fault with the

emissions control system, different

messages are displayed in the Driver

Information Centre. The messages

and the restrictions are a legal

requirement.

emission control system.

Refilling AdBlue

Caution

Note

Refill the AdBlue tank to a level of at

least 10 l, to ensure that the new

AdBlue level is being detected.

2. If the fault is confirmed by the

emission control system, the

following message will be

displayed:

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.
