Driving economically ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
Activation
Press ECO. Control indicator ECO
illuminates in the instrument cluster when activated.
142Driving and operatingIf 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 99.
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 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.
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.
AdBlue level indicator
The current AdBlue percentage
remaining can be shown in the Driver
Information Centre 3 103.
Driving and operating143Press button on end of wiper lever
repeatedly until the 'AdBlue
percentage remaining' menu is
displayed.
Level warnings
The AdBlue consumption is approx.
3.5 l per 1000 km and depends on the driving behaviour.
If the AdBlue level falls below a
certain value, a level warning will be
displayed in the Driver Information
Centre 3 103. Additionally, control
indicator Y illuminates continuously
together with a warning chime.
Refill the AdBlue tank as soon as
possible. Refer to "Refilling AdBlue"
below.
If AdBlue is not refilled within a certain distance, further level warnings are
displayed in the Driver Information
Centre depending on the current
AdBlue level.
Engine restarts prevented
Subsequent requests to refill AdBlue
and finally the announcement that an
engine restart will be prevented are
displayed in the Driver Information
Centre.
Note
These restrictions are a legal
requirement.
Before the prevention of an engine restart, a warning message with
0 km is displayed in the Driver
Information Centre, indicating that
after switching off the ignition an
engine restart will be prohibited.
After the prevention of an engine
start, a warning message is displayed in the Driver Information Centre
reminding the driver that AdBlue level is insufficient.To allow the engine to be restarted,
the tank should be refilled completely
or with a volume of at least 10 l of
AdBlue, depending on AdBlue
consumption.
Warning stages: level warnings,
engine restarts prevented
1. Y illuminates after ignition is
switched on with warning
message LEVEL ADBLUE LOW :
Driving is possible without any
restrictions.
Refill the AdBlue tank as soon as
possible.
2. Y illuminates during driving with
warning message TOP UP
ADBLUE :
Possible loss of engine power.
Refill the AdBlue tank as soon as
possible.
3. Y illuminates during driving with
warning message XXX KM STOP
ADD ADBLUE :

20 km/h after switching the engine
off and on again until the range is
reduced to 0 km.
144Driving and operatingRefill the tank completely or with a
volume of at least 10 l of AdBlue
(depending on AdBlue
consumption) as soon as
possible.
4. Y illuminates during driving with
warning message 0 KM STOP
ADD ADBLUE :
The engine cannot be restarted
after switching off the ignition.
To allow the engine to be
restarted, refill the tank
completely or with a volume of at
least 10 l of AdBlue (depending on AdBlue consumption) as soon as
possible.
Illumination of control indicator Y may
be accompanied by a warning chime.
Warning chimes 3 105.
High emission warnings If the exhaust emission rises above a
certain value, warnings similar to the
range warnings as described above will be displayed in the Driver
Information Centre. Control indicator
Y illuminates continuously together
with j and a warning chime.Requests to have the exhaust system
checked and finally the
announcement that an engine restart
will be prevented are displayed in the
Driver Information Centre.
Note
These restrictions are a legal
requirement.
At an AdBlue range of 1100 km, a
warning message is displayed in the
Driver Information Centre showing
the remaining distance the vehicle
can travel before engine restarts are
prevented. This warning message is
repeated every 100 km.
Seek the assistance of a workshop as soon as possible.
Warning stages: high emission
warnings
1. Y and j illuminate with warning
message CHECK ANTI-
POLLUTION :
Fault in the system that may result in a loss of engine power.
Seek the assistance of a
workshop as soon as possible.2. Y and j illuminate with warning

KM FAIL :
Indicates that in less than
1100 km an engine restart will be
prohibited after switching off the

Driving and operating145Refilling AdBlueCaution
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.
Note
If AdBlue must be refilled at very low temperatures, the refilling of AdBlue
may not be detected by the system.
In this case, park the vehicle in a
space with a higher ambient
temperature until AdBlue is
liquefied.
Note
If engine starting is prohibited due to low AdBlue level, we recommend
refilling the tank completely or with a volume of at least 10 l of AdBlue
(depending on AdBlue
consumption).
Avoid minor top-ups (e.g. less than
10 l), otherwise the system may not
detect a refill.
Note
When unscrewing the protective cap from the filler neck, ammonia fumesmay emerge. Do not inhale as the
fumes have a pungent smell. The fumes are not harmful by inhalation.
The vehicle must be parked on a level surface.The filler neck for AdBlue is located
behind the fuel filler flap, located on
the left-hand side of the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked and the left- hand door is opened.9 Danger
Vehicles with stop-start system:
The engine must be switched off
and the ignition key removed, to
avoid risk of engine being
restarted automatically by the
system.
Capacities 3 222.
Filling station
9 Danger
Follow the operating and safety
instructions of the filling station
when refilling AdBlue.
1. Switch off engine and remove key
from ignition switch.
146Driving and operating2. Open left-hand door and pull fuelfiller flap to open.
3. Unscrew protective cap anticlockwise from the filler neck.
Caution
The AdBlue protective cap is the
blue lower cap (arrowed in
illustration), and the fuel filler cap
is the black upper cap 3 161.
In case of incorrect refilling, do not switch on ignition. Seek the
assistance of a workshop
immediately.
4. Fully insert the pump nozzle into the filler neck and switch it on.
5. When refilling is complete, mount the protective cap and turn
clockwise until it engages.
6. Close fuel filler flap and left-hand door.
AdBlue canister Note
Only use the designated AdBlue
canisters for refilling, to prevent a
topping-up of too much AdBlue.
Additionally, the fumes in the tank
are captured in the canister and do
not emerge.
Note
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
1. Switch off engine and remove key
from ignition switch.
2. Open left-hand door and pull fuel filler flap to open.
3. Unscrew protective capanticlockwise from the filler neck.
Caution
The AdBlue protective cap is the
blue lower cap (arrowed in
illustration), and the fuel filler cap
is the black upper cap 3 161.
In case of incorrect refilling, do not switch on ignition. Seek the
assistance of a workshop
immediately.
4. Open AdBlue canister.
