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 AdBlue tank should be filled
completely. This must be done if the
warning message regarding
prevention of an engine restart is
already displayed.
The vehicle must be parked on a level surface.
The filler neck for AdBlue is located
behind the fuel filler flap, which is
located at right rear side of the

146Driving and operatingManual transmission
To engage reverse on 6-speed
transmission, depress the clutch
pedal, pull the ring under the selector
lever and move the selector lever
quite to the left and front.
If the gear does not engage, set the
selector lever to 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.
When clutch slip is detected for a specific time, the engine power will be reduced. A warning is displayed in the
Driver Information Centre. Release
the clutch.Caution
It is not advisable to drive with the hand resting on the selector lever.
Gear shift indication 3 95.
Stop-start system 3 135.
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 the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing the 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.
Control indicator m 3 94.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
Driving and operating147ABS 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.
When braking in an emergency, the
hazard warning flashers are switched on automatically depending on the
force of deceleration. They are
switched off automatically the first
time you accelerate.
After starting off, the system performs
a self-test which may be audible.
Control indicator u 3 95.
Fault9 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.
Have the cause of the fault remedied
by a workshop.
Parking brake
9 Warning
Before leaving the vehicle, check
parking brake status. Control
indicator m must illuminate

parking brake is applied 3 94 . The
electric parking brake operates automatically with adequate force.
Before leaving the vehicle, check
the electric parking brake status.
Control indicator m 3 94.
148Driving and operatingThe electric parking brake can always
be activated, even if the ignition is off.
Do not operate electric parking brake
system too often without engine
running as this will discharge the vehicle battery.
Releasing
Switch on ignition. Keep foot brake
pedal depressed and then push
switch m.
Drive away function
Vehicles with manual transmission:
Depressing the clutch pedal and then
slightly releasing the clutch pedal and slightly depressing the accelerator
pedal releases the electric parking
brake automatically. This is only
possible if the automatic operation of the electric parking brake is activated.
It is not possible when switch m is
pulled at the same time.
Vehicles with automatic transmission: Engaging D and then depressing the
accelerator pedal releases the
electric parking brake automatically.
This is only possible if the automaticoperation of the electric parking brake
is activated. It is not possible when
switch m is pulled at the same time.
Braking when vehicle is moving
When the vehicle is moving and the
switch m is kept pulled, the electric
parking brake system will decelerate the vehicle. As soon as the switch
m is released, braking will be
stopped.
The antilock brake system and the Electronic Stability Control stabilise
the vehicle while the switch m is kept
pulled. If an error of the electric
parking brake occurs, a warning
message is displayed in the driver
information centre. If the antilock
brake system and the Electronic
Stability Control fail, one or both
indicators i and J illuminate in the
instrument cluster. In this case,
stability can only be provided by
repeatedly pulling and pushing the
switch m until the vehicle is
immobilised.Automatic operation
Automatic operation includes
automatic application and automatic
release of the electric parking brake.
The electric parking brake can also be
applied or released manually by using
the switch m.
Automatic application: ● The electric parking brake is automatically applied when the
vehicle is stationary and the
ignition is switched off.
● j illuminates in the instrument
cluster and a display message
pops up to confirm the
application.
Automatic release: ● Parking brake releases automatically after moving off.
● j extinguishes in the
instrument cluster and a display message pops up to confirm the
release.
150Driving and operatingRide control systems
Electronic Stability Control and Traction Control system
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip.
As soon as the vehicle starts to
swerve (understeer / oversteer),
engine output is reduced and the wheels are braked individually.
ESC operates in combination with the Traction Control system (TC). It
prevents the driven wheels from
spinning.
The TC is a component of the ESC.
Traction Control improves driving
stability when necessary, regardless
of the type of road surface or tyre grip,
by preventing the driven wheels from
spinning.
As soon as the driven wheels starts to spin, engine output is reduced and
the wheel spinning the most is brakedindividually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
ESC and TC are operational after
each engine start as soon as the
control indicator b extinguishes.
When ESC and TC operate, b
flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator b 3 96.
Deactivation
ESC and TC can be deactivated,
everytime it is required: press a.
The LED in the button a illuminates.
A status message appears in the
Driver Information Centre when ESC
and TC are deactivated.
ESC and TC are reactivated by
pressing the a button again, by
applying the brake or in the case that
the vehicle is driven faster than
50 km/h.
The LED in the button a extinguishes
when ESC and TC are reactivated.
Driving and operating153DeactivationBriefly press SPORT. Sport mode is
deactivated the next time the ignition
is switched on.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds above 40 km/h.
Additionally at least the third gear
must be engaged on manual
transmission, on automatic
transmission position D or the second
or a higher gear in position M must be
selected.
Deviations from the stored speeds may occur when driving uphill or
downhill.
The system maintains the vehicle
speed at the preset speed by the
driver, without any action on the
accelerator pedal.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal firmly.
The status and preset speed is
displayed in the Driver Information Centre.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
Control indicator m 3 98.
158Driving and operatingDeactivation of the functionality
Press Ñ, speed limiter is in pause
mode and a message is displayed.
The vehicle is driven without speed
limiter.
Speed limiter is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.
Resume limit speed
Press Ñ, the stored speed limit will be
obtained.
Switching off the system
Press ß, the speed limiter mode is
deselected and the speed limit indication extinguishes in the Driver
Information Centre.
Pressing m to activate cruise control
deactivates speed limiter.
The preset speed remains in the
memory when the ignition is switched
off.Fault
In the event of a speed limiter fault,
the speed is cleared resulting in
flashing of the dashes.
The speed limit recognition may not
operate correctly if traffic signs do not
comply with the Vienna Convention
on Road Signs and Signals.
Adaptive cruise control The adaptive cruise control is an
enhancement to the conventional
cruise control with the additional
feature of maintaining a certain
following distance to the vehicle
ahead. It uses radar and camera
sensors to detect the vehicles ahead.
If no vehicle is detected in the driving path, the adaptive cruise control will
behave like a conventional cruise
control.
The adaptive cruise control
automatically decelerates the vehicle
when approaching a slower moving vehicle. It then adjusts the vehicle
speed to follow the vehicle ahead at
the selected following distance. The
vehicle speed increases or decreasesto follow the vehicle ahead, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
If the vehicle ahead accelerates or changes lane, the adaptive cruise
control progressively accelerates the
vehicle to return to the stored set
speed. If the driver operates a the turn lights to overtake a slower vehicle, the
adaptive cruise control allows the
vehicle to temporarily approach the
vehicle ahead to help passing it.
However, the set speed will never be
exceeded.
The adaptive cruise control can store set speeds over 30 km/h for manual
transmission. If the vehicle ahead is
moving too slowly and the selected
following distance cannot be
maintained anymore, a warning
chime is given and a message is
displayed in the Driver Information
Centre. The message prompts the
driver to take back control of the
vehicle. On vehicles with automatic
transmission, the system can brake
the vehicle until a full stop.
Driving and operating1599Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the button
Ñ have priority over any adaptive
cruise control operation.
Switching on the system
Press C, the symbol C is indicated in
the Driver Information Centre. The system is still not active.
Activation of the functionality
Setting speed by the driver
The adaptive cruise control has to be switched on manually at a speed
between 30 km/h and 180 km/h. For
vehicles with automatic transmission, the automatic selector lever must be
in position D or M.
Accelerate to the desired speed and
move the thumb wheel to SET/-. The
current speed is stored and
maintained.The speed value is indicated in the
Driver Information Centre.
The preset speed can then be
changed by moving thumb wheel to
RES/+ to increase or SET/- to
decrease the speed. Move thumb wheel repeatedly to change speed in
small steps, move and hold to change
speed in large steps.
When the adaptive cruise control is
operating, the stop-start system is
automatically deactivated.
