Driving and operating177
■ Antilock brake system (ABS) withcornering brake control (CBC)
■ Automatic transmission
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 manual selected driving
mode 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 example, TOUR mode is
selected and whilst driving on a
winding road a sudden hard brake is
necessary, DMC will detect the
dynamic vehicle condition and
178Driving and operating
changes the settings for suspension
to SPORT mode to increase vehicle
stability.
When the driving characteristic or the
dynamic vehicle state returns to
former state, DMC will change the
settings to the preselected driving
mode.

Active Emergency Braking Active emergency braking can help to reduce the damage from crashes with vehicles and obstacles directly
ahead, when a collision can no longer be avoided either by manual braking
or by steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert 3 189.
The feature uses various inputs (e.g.
radar sensor, brake pressure, vehicle speed) to calculate the probability ofa frontal collision.
Active emergency braking operates automatically above walking speed,
provided that Auto collision
preparation setting is not deactivated
in the vehicle personalisation menu 3 131.
The system includes: ■ brake preparation system
■ emergency automatic braking
■ forward looking brake assist9 Warning
This system is not intended to
replace the driver responsibility of driving the vehicle and looking
ahead. Its function is limited to
supplemental use only. The driver
shall continue to apply the brake
pedal as the driving situation
dictates.
Brake preparation system
When approaching a vehicle ahead
so quickly that a collision is likely, the brake preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that braking can occur more rapidly.
Emergency automatic braking After the brake preparation and just
before the imminent collision, this
function automatically applies limited
braking to reduce the impact speed of
the collision.
Forward looking brake assist
In addition to brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. In this way,
depressing the brake pedal slightly

Advanced parking assist9 Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
advanced parking assist.
The advanced parking assist system manoeuvres the driver into a parkingslot by giving instructions in the DIC
and acoustic signals. The driver must
control acceleration, braking, steering and gear shifting.
The system uses the sensors of the
front-rear parking assist in
combination with two additional
sensors on both sides of the front and rear bumper.
200Driving and operating
The parking slot suggestion of the
system is accepted when the vehicle is stopped by the driver within
10 metres after the "Stop" message is given. The system calculates the
optimal route into the parking slot. Then it manoeuvres the driver into the
slot by giving detailed instructions.The instructions in the display show:
■ A hint when driving faster than 18 mph.
■ The demand to stop the vehicle, when a parking slot is detected.
■ The direction of driving during the parking manoeuvre.
■ The steering wheel position during parking.
■ For some of the instructions a progress bar is shown.A successful parking manoeuvre is
indicated by the 'End position'
symbol.
Always pay attention to the sound of
the front-rear parking assist.
Continuous sound means that the
distance to an obstacle is less than
approx. 30 cm.
