Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards the kerb.
● Close the windows.
● Remove the ignition key from the ignition switch. Turn the
steering wheel until the
steering wheel lock is felt to
engage.

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 3 100.
140Driving and operatingPress button on end of wiper lever
repeatedly until the 'AdBlue
percentage remaining' menu is
displayed.
Level warnings
The AdBlue consumption is approx.
3.0 litres per 600 miles (941 mpg) 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 3 100. 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.
Notice
These restrictions are a legal
requirement.
Before the prevention of an engine restart, a warning message with
0 miles 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 ten litres
of AdBlue, depending on AdBlue
consumption.

Refilling 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.
Notice
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.
Notice
If engine starting is prohibited due to low AdBlue level, we recommend
refilling the tank completely or with a volume of at least ten litres of AdBlue(depending on AdBlue
consumption).
Avoid minor top-ups (e.g. less than ten litres), otherwise the system may
not detect a refill.
Notice
When unscrewing the protective cap from the filler neck, ammonia fumes
may 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.

144Driving and operatingCaution
The AdBlue protective cap is the
blue lower cap (arrowed in
illustration), and the fuel filler cap
is the black upper cap 3 158.
In case of incorrect refilling, do not switch on ignition. Seek the
assistance of a workshop
immediately.
4. Open AdBlue canister.
5. Mount one end of the hose on the
canister and screw the other end
on the filler neck.
6. Lift the canister until it is empty, or
until the flow from the canister has
stopped. This can take up to five
minutes.
7. Place the canister on the ground to empty the hose, wait 15
seconds.
8. Unscrew the hose from the filler neck.
9.Mount the protective cap and turn
clockwise until it engages.
10. Close fuel filler flap and left-hand door.
Notice
Dispose of AdBlue canister
according to environmental
requirements. Hose can be reused
after flushing with clear water before
AdBlue dries out.
Notice
Allow the vehicle to idle for at least
ten seconds to allow the system to
detect the AdBlue refill.
Failure to observe this procedure will
result in the system only recognising the AdBlue refill after approx.
20 minutes of driving.
If the AdBlue refill is detected
successfully, AdBlue level warnings
will disappear.
If the AdBlue refill is not detected
some time after running the engine,
seek the assistance of a workshop.
Filler cap
Only use genuine filler caps. AdBlue
tank has a special filler cap.Fault

146Driving and operatingControl indicator R 3 96.
Vehicle messages 3 101.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting-off, the system performs
a self-test which may be audible.
Control indicator u 3 97.
Fault
If control indicator u does not go out
a few seconds after the ignition is switched on, or if it illuminates whiledriving, there is a fault in the ABS.
Control indicator F 3 96 may also
illuminate in the instrument cluster
together with a corresponding
message in the Driver Information
Centre. The brake system remains operational but without ABS
regulation.9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
If control indicators u, F , R 3 96
and C 3 96 illuminate, there is a fault
in the braking system. A
corresponding message also
appears in the Driver Information
Centre 3 100. Have the cause of the
fault remedied by a workshop.
