SPORT mode
The settings of the systems are
adapted to a sportier driving style:
■ Damping of shock absorbers reacts
more stiffly to provide better contact with the road surface.
■ The engine reacts more quickly to the accelerator pedal.
■ Steering support is reduced.
■ Shift points of automatic transmission occur later.
■ With SPORT mode activated, the illumination of main instruments
changes from white to red.
TOUR mode
The settings of the systems are
adapted to a comfort driving style:
■ Damping of shock absorbers reacts
more softly.
■ Accelerator pedal reacts with standard settings.
■ Steering support is in standard mode.
■ Shift points of automatic transmission occur in a comfort
mode.
■ Illumination of main instruments is white.
NORMAL mode
All settings of the systems are
adapted to standard values.
Drive mode control Within each manually selected drivingmode SPORT, TOUR or NORMAL,
the Drive Mode Control (DMC)
detects and analyses continuously
the real driving characteristic,
responses by the driver, and the
active dynamic state of the vehicle. If
necessary, the control unit of DMC
automatically changes the settings
within the selected driving mode or,
when recognising greater variations,
the driving mode is changed for the
length of variation.
If, for example, NORMAL mode is
selected and DMC detects a sporty
driving behaviour, DMC changes
several settings of the Normal mode
into sporty settings. The DMC
changes to SPORT mode in case of
very sporty driving behaviour.
If, for another example, TOUR mode
is selected and whilst driving on a
winding road a sudden hard brake is
necessary, DMC will detect the
150Driving and operating
dynamic vehicle condition and
changes the settings for suspension
to SPORT mode to increase vehicle
stability.
When the driving characteristic or the
dynamic vehicle state returns to the
former state, DMC will change the
settings to the preselected driving
mode.
Personalised settings in the
SPORT mode The driver can select the functions of
the SPORT mode when SPORT
button is pressed. These settings can
be changed in the Settings menu in
the Info-Display. Vehicle

General information
9Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the valid
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. He shall always be ready to take action and apply the
brakes.
System limitations
The system is designed to warn only for vehicles, but may react also on
other objects.
In the following cases, forward
collision alert may not detect a vehicle
ahead or sensor performance is
limited:
■ on winding roads,
■ when weather limits visibility, such as fog, rain, or snow,
■ when the sensor is blocked by snow, ice, slush, mud, dirt, or
windscreen damage.
Following distance
indication The following distance indication
displays the distance to a preceding
moving vehicle. The front camera in
the windscreen is used to detect the
distance of a vehicle directly ahead in
the vehicle's path. It is active at
speeds above 25 mph.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 95 . Press
the MENU button on the turn signal
lever to select Vehicle Information
Menu X and turn the adjuster
wheel to choose following distance
indication page.
The minimum indicated distance is
0.5 seconds.
170Driving and operating
FaultThe traffic sign assistant system may
not operate correctly when:
■ the area of the windscreen, where the front camera is located, is notclean
■ traffic signs are completely or partially covered or difficult to
discern
■ there are adverse environmental conditions, e.g. heavy rain, snow,
direct sunlight or shadows. In this
case No Traffic Sign Detection due
to Weather is indicated on the
display
■ traffic signs are incorrectly mounted
or damaged
■ traffic signs do not comply with the Vienna Convention on traffic signs
(Wiener Übereinkommen über
Straßenverkehrszeichen)Caution
The system is intended to help the driver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning systemobserves the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
■ no operation of turn signals
■ no brake pedal operation
■ no active accelerator operation or speeding-up
■ no active steering
If the driver is performing these
actions, no warning will be issued.
Activation
The lane departure warning system isactivated by pressing the ) button.
The illuminated LED in the button

Furthermore, fuel consumption is dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
The bulb outage detection function for
trailer brake light cannot detect a
partial bulb outage, e.g. in case of 4 x
5 Watt bulbs, the function only detects lamp outage when only a single
5 Watt lamp remains or none remain.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball
bar for towing. Always keep the
coupling ball bar in the vehicle.Driving characteristics and
towing tips
Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements.
For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than
1200 kg the use of a stabiliser is
strongly recommended when driving
above 50 mph.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 238.
