Driving and operating171Temporary manual mode in drive
mode D
Manual paddle shifting is also
possible in automatic mode D. Upon
completion of manual shifting
operation, transmission changes to
automatic mode D after a defined
time.
To interrupt manual mode, do one of
the following:
● Press < paddle for 1 second.
● Move selector lever towards the left to manual mode and back to
position D.
If the vehicle is at a standstill and
engine is idling, the transmission will remain in temporary manual mode. It
changes to automatic mode when
accelerator pedal is operated for a
defined time, and no paddle shifting
at the steering wheel is performed.
General
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,the shift is not executed. This can
cause a message in the Driver
Information Centre.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shift indication
The symbol R with a number below it
is indicated when gearshifting is
recommended for fuel saving
reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● The automatic neutral shift function automatically shifts to
idling when the vehicle is stopped
with a forward gear engaged and the brake pedal is pressed.● When SPORT mode is engaged,
the vehicle shifts at higher engine
speeds (unless cruise control is
on). SPORT mode 3 179.
● Special programmes automatically adapt the shifting
points when driving up inclines or down hills.
● When starting off in snowy or icy conditions or on other slippery
surfaces, the electronic
transmission control selects a
higher gear automatically.
Kickdown
If the accelerator pedal is pressed
down completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.
Overheat protection In the event of transmission-
overheating due to high outside
temperatures or sporty driving style,
the torque and the maximum speed of
the engine can be temporarily
reduced.

Drive systems
All-wheel drive
The All-wheel drive system enhances
driving characteristics and stability,
and helps to achieve the best
possible driveability regardless of
ground surface. The system is always
active and cannot be deactivated.
The torque is distributed steplessly
between the wheels of the front and rear axle, depending on the driving
conditions. Additionally the torque
between the rear wheels is distributed
depending on the surface.
For optimum system performance,
the vehicle's tyres should not have
varying degrees of wear.
If a service message is displayed in
the Driver Information Centre, the
system may have limited functionality (or be completely disabled in some
cases, i.e. the vehicle switches to
Front-wheel drive). Seek the
assistance of a workshop.

Driving and operating179Interactive driving systemFlex Ride
Flex Ride driving system allows the
driver to select between three driving
modes:
● SPORT mode: press SPORT,
LED illuminates.
● TOUR mode: press TOUR, LED
illuminates.
● NORMAL mode: neither SPORT
nor TOUR is pressed, no LED
illuminates.
Deactivate SPORT mode and TOUR
mode by pressing corresponding
button once more.
In each driving mode Flex Ride
networks the following electronic
systems:
● Continuous Damping Control
● Accelerator Pedal Control
● Steering Control
● All-wheel drive
● Electronic Stability Control (ESC)● Antilock Brake System (ABS)
with cornering 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 providebetter contact with the road
surface.
● The engine reacts more quickly to the accelerator pedal.
● Steering support is reduced.
● Engine torque of All-wheel drive is distributed more to the rear
axle.
● Shift points of automatic transmission occur later.
● Depending on the instrument cluster the colouring of the
display will be adapted.
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.
180Driving and operating● Steering support is in standardmode.
● Engine torque of All-wheel drive is distributed mainly to the front
axle.
● Shift points of automatic transmission occur in a comfort
mode.
NORMAL mode
All settings of the systems are
adapted to standard values.
Drive mode control
Within each manually 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 another 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
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.
