● 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 foot brake 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.
● Lock the vehicle 3 23
● Activate the anti-theft locking system 3 32 and anti-theft alarm
system 3 33.Engine exhaust9 Danger
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.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
122Driving and operating9Warning
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 percentage remaining
The current Adblue percentage
remaining can be shown in the Driver
Information Centre (DIC) 3 89.
Press button on end of wiper lever
repeatedly until the 'Adblue
percentage remaining' menu is

certain value, a level warning will be
displayed in the Driver Information
Centre (DIC) 3 89. Additionally,
control indicator Y illuminates
continuously together with a warning
chime.
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.
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.

illuminate in the instrument cluster
together with a corresponding
message in the Driver Information
Centre (DIC). 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 85
and C 3 85 illuminate, there is a fault
in the braking system. A

Ride control systems
Traction Control system The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
ignition is switched on and control
indicator b extinguishes in the
instrument cluster. A corresponding message also appears in the Driver
Information Centre (DIC) 3 89.
When TC is active b flashes.9 Warning

Electronic stability program The Electronic Stability Program
(ESP® Plus
) improves driving stability
when necessary, regardless of the
type of road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. Thisconsiderably improves the driving
stability of the vehicle on slippery road
surfaces.
ESP® Plus
is operational as soon as
the ignition is switched on and control
