126Driving and operatingAdblue gauge
The current fluid level remaining is
shown in the Adblue gauge 3 79.
Level warnings
The AdBlue consumption is approx.
3.5 litres per 1000 km and depends
on the driving behaviour.
Version with level warnings in the
Driver Information Centre (DIC)
If the AdBlue level falls below a
certain value, a level warning will be
displayed in the Driver Information
Centre (DIC) 3 89.
Additionally, control indicator Õ
illuminates continuously together with a warning chime.
Refill 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

128Driving and operatingWhen the fault is critical, Õ and A
flash continuously and after the next
engine restart the vehicle speed will
be limited to approx. 12 mph.
Notice
These restrictions are a legal
requirement.
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.
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
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 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 filler flap located on the
right-hand side of the vehicle.
The filler flap can only be opened if the vehicle is unlocked and the right-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.

6. Close filler flap and right-hand door.
AdBlue canister Notice
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 filler flap to open.
3. Unscrew protective cap anticlockwise from the filler neck.

8. Mount the protective cap and turn
clockwise until it engages.
9. Close filler flap and right-hand door.
Notice
Dispose of AdBlue canister and
hose according to environmental requirements.
Filler cap
Only use genuine filler caps. Adblue
tank has a special filler cap.
Fault
If the system detects an operating fault, control indicator Õ illuminates
together with A and a warning
chime. Seek the assistance of a
workshop immediately.
Depending on version, a
corresponding message may also
appear in the DIC 3 89.

132Driving and operatingwarning may sound as a signal to
depress the brake pedal or apply the
parking brake.
Switch off engine if stopping for a
lengthy period, e.g. in traffic jams.
When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the brake pedal has not
been depressed.
Engine braking
Automatic mode
When driving downhill, the manual
transmission automated does not
shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect,
select a lower gear in good time when
driving downhill.Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.
Parking
Apply the parking brake. The most
recently engaged gear (see
transmission display) remains
engaged. With N, no gear is engaged.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
If the ignition is not switched off, or the
parking brake has not been applied, a
warning chime will sound upon
opening the driver's door.
Manual mode If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, theshift is not executed. This prevents
the engine from running at too low or too high an engine speed.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
If engine speed is too high, the
transmission only switches to a higher gear via kickdown.
Electronic driving programmes
Winter mode V

Driving and operating133Activate the Winter mode if you have
problems starting off on a slippery
road surface.
Activation
Press V. Control indicator V is shown
in the transmission display. The
transmission switches to automatic
mode and the vehicle starts off in a
suitable gear.
Deactivation
The Winter mode is switched off by:
● pressing V again
● turning off the ignition
● switching to manual mode
In order to protect the transmission at
extremely high clutch temperatures,
an intermittent audible warning may
sound. In such cases, depress the
brake pedal, select "N" and apply the parking brake to allow the clutch to
cool down.Laden mode kg
It is possible to use the Laden mode
in both manual and automatic modes. In both cases, the gearshifting
patterns are adapted automatically
for carrying an increased payload.
Activation
Press kg. Control indicator kg is
shown in the transmission display.
The transmission will then select
optimized gearshift patterns.
Deactivation
The Laden mode is switched off by:
● pressing kg again
● turning off the ignition
Kickdown If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower gear
depending on engine speed. Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.
Fault
In the event of a fault, control indicator W is shown in the transmission
display. Continued driving is possible
provided the vehicle is driven with
care and anticipation.
Have the cause of the fault remedied
by a workshop.

136Driving and operatingBrake assistIf the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Brake assist is not available during an
Autostop. Stop-start system 3 119.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline (with the
selector lever in a forward gear or
reverse gear), the brakes remain on
for a further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Caution
The Hill start assist cannot
completely prevent vehicle
movement in all situations
(extremely steep gradients, etc.).
If necessary, depress the brake
pedal to prevent the vehicle from
rolling forwards or backwards.
The Hill start assist is not active
during an Autostop. Stop-start system 3 119.
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.
