Control indicator k illuminates.
A status message appears in the
Driver Information Centre when TC is
deactivated.
When TC is deactivated, ESC
remains active but with higher control threshold.
TC is reactivated by pressing t again.
A status message pops up in the Driver Information Centre when TC is reactivated.
TC is also reactivated the next time
the ignition is switched on.
Fault
If there is a fault in the system the
control indicator b illuminates
continuously and a message appears
in the Driver Information Centre. The
system is not operational.
Have the cause of the fault remedied
by a workshop.
Electronic Stability Control 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 drive wheels from
spinning.
Torque distribution is a special
feature that allocates the torque to the drive wheels before the ESC
intervenes. When cornering, the
wheels on the inner curve are braked
individually. Additionally, engine
torque will be delivered to the drive wheel on the outer curve. This
reduces the tendency of
understeering and improves traction
when cornering fast.
ESC is operational after each engine
start as soon as the control indicator
b extinguishes.
When ESC operates b flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.

Interactive driving system Flex Ride Flex Ride driving system allows thedriver to select between three driving
modes:
● SPORT mode: press SPORT,
LED illuminates.
● TOUR mode: press TOUR, LED
illuminates.
● AUTO mode: neither SPORT nor
TOUR is pressed, no LED
illuminates.
Deactivate SPORT mode or TOUR
mode by pressing corresponding
button once more.
In each driving mode Flex Ride
adjusts the following electronic
systems:
● electronic damping control
● accelerator pedal control
● electronic power steering control
● automatic transmission

Driving and operating185● adaptive cruise control
● all-wheel drive
● engine sound enhancement
● instrument cluster theme
SPORT mode
The settings of the systems are
adjusted for a sportier driving style:
● Damping of shock absorbers is set up for increased handling andagility.
● The engine reacts more quickly to accelerator pedal changes.
● Steering support is sportier.
● Automatic transmission shift points optimised for sporty
driving.
● Adaptive cruise control is adjusted for a sportier driving
style.
● All-wheel drive supports active sporty driving of the vehicle.
● Engine sound enhancement intensifies interior engine sound
in a sporty manner.
● Cluster theme changes to sport.
TOUR modeTOUR mode adjusts the settings of
the systems for a comfortable driving
style.
● Damping of shock absorbers is adapted for increased driving
comfort.
● Steering efforts are reduced. ● Adaptive cruise control is adjusted for a more relaxed
driving style.
AUTO mode
All settings of the systems are preset
to standard values optimised for daily driving (default mode). This is the fully
adaptive mode, adjusting systems to
both comfort and sport settings
depending on driving style and driving
situation.
Adaptive drive mode control
Within each manually selected driving mode SPORT , TOUR or AUTO , Drive
Mode Control (DMC) detects and
analyses continuously the driving situation and the driver's driving style.
If necessary, DMC automatically
adjusts damping and steering for the
duration of the occuring situation.
Page 188 of 323

186Driving and operatingIf, for example, normal settings are
active in AUTO mode and DMC
detects a sporty driving behaviour, it
automatically changes systems into
sporty settings unless the driver
deselects sporty damping or steering
in the Sport Mode Customisation .
If, for another example, comfort settings are active in TOUR mode
and whilst driving on a winding road a sudden hard brake is necessary,DMC will detect the dynamic vehicle
condition and changes the settings
for suspension back to normal
(default) setting to enhance vehicle
stability.
When the driving characteristic or the
dynamic vehicle state returns to the
former state, DMC will change to
preselected settings.Flex Ride visualisation menu

systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver stays in full control of
the vehicle and accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation and follow applicable
traffic rules.
Cruise control
The cruise control can store and
maintain speeds of approx. 30 km/h
to maximum vehicle speed.
Deviations from the stored speeds
may occur when driving uphill or
downhill.
Activating in first gear is not possible.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
Illustrations show different versions.
