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, except
activating the kickdown function.
Gear shift indication
The symbol R or S with a number
beside it is indicated when gear
shifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
● 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.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission control
enables the driver to manually
select first, second or third gear
for starting off.
Kickdown
Pressing down the accelerator pedal
beyond the kickdown detent will lead
to maximum acceleration
independent of the selected driving
mode. The transmission shifts to a
lower gear depending on engine
speed and shifts to a higher gear at
high engine revolutions.
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.
178Driving and operating
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.

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.

● 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 versions except GSi: 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.
Normal mode
GSi versions only: All settings of the
systems are preset to standard
values optimised for daily driving
(default mode). This mode keeps the
standard values independent of
driving style or driving situation.
Driving and operating181Adaptive 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.
If, 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.Settings
The settings of drive modes can be
changed in the vehicle
