114Driving and operatingStarting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
vehicle battery.

Overrun cut-off The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It restarts the engine
automatically as soon as the clutch
pedal is depressed.
A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle battery is sufficiently charged
for a restart.
118Driving and operatingActivation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.

not available 3 127.
Caution
The steering assist may be
reduced during an Autostop.
Driving and operating123Refill the Adblue tank as soon as
possible. Refer to " Refilling AdBlue"
below.
Driving is possible without any
restrictions.
If AdBlue is not refilled within a certain
distance, further level warnings are
displayed in the DIC 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 DIC.
Notice
These restrictions are a legal
requirement.
Before the prevention of an engine
restart, a warning message with
0 miles is displayed in the DIC,
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 DIC reminding the driver that
AdBlue level is insufficient.To allow the engine to be restarted,
the tank should be filled with at least
10 litres of AdBlue.
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 DIC. Control
indicator Y illuminates continuously
together with F and a warning chime.
Requests to have the exhaust system checked and finally the
announcement that an engine restart
with be prevented are displayed in the
DIC.
Notice
These restrictions are a legal
requirement.
At an AdBlue range of approx.
680 miles, a warning message is
displayed in the DIC showing the
remaining distance the vehicle can
travel before engine restarts are
prevented. This warning message is
repeated approx. every 60 miles.
Seek the assistance of a workshop as soon as possible.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.
124Driving and operatingNotice
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
adding a volume of at least 10 litres
of AdBlue when refilling. Avoid minor
top-ups (e.g. less than 5 litres),
otherwise the system may not detect a refill.
Notice
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.Caution
In case of misfuelling, do not
switch on ignition.
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 3 195.

6. Close fuel filler flap and left-hand door.
Driving and operating125AdBlue canisterNotice
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.
Notice
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
1. Switch off engine and remove key
from ignition switch.
2. Pull fuel filler flap to open.3. Unscrew protective cap (2) anticlockwise from the filler neck.
4. Open AdBlue canister.
5. Mount one end of the hose on the

on the filler neck.
6. Lift the canister until it is empty.
7. Unscrew the hose from the filler neck.
8. Mount the protective cap and turn
clockwise until it engages.
9. Close fuel filler flap and left-hand door.
Notice
Dispose of AdBlue canister and
hose according to environmental requirements.
Fault
If the system detects an operating fault, control indicator Y illuminates
together with F and a warning chime.
Seek the assistance of a workshop
immediately.
A corresponding message appears in the DIC 3 89.Manual transmission
To engage reverse, with the vehicle
stationary depress the clutch pedal, pull up the collar on the selector lever
and engage the gear against the
resistance.
If the gear does not engage, set the
lever in neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch pedal completely. Do not use the
pedal as a foot rest.
126Driving and operatingCaution
It is inadvisable to drive with hand
resting on the selector lever.
Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
If control indicator R illuminates in
the instrument cluster while driving
and a corresponding message
appears in the Driver Information
Centre (DIC) 3 89, there is a fault in
the braking system. Seek the
assistance of a workshop
immediately.Control indicator R 3 85.
Vehicle messages 3 90.
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 86.
Fault
If control indicator u does not go out
a few seconds after the ignition is
switched on, or if it illuminates while
