the vehicle shifts at higher engine
speeds (unless cruise control is
on). SPORT mode 3 157.
● Special programmes automatically adapt the shiftingpoints 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.
Fault
In the event of a fault, control indicator g illuminates. Additionally, a code
number or a vehicle message is
displayed in the Driver Information
Centre. Vehicle messages 3 99.The transmission no longer shifts
automatically. Continued travel is
possible with manual shifting.
Only the highest gear is available.
Depending on the fault, 2nd gear may also be available in manual mode.

Driving and operating155Ride control systems
Traction Control system The Traction Control system (TC) is a
component of the Electronic Stability
Control (ESC) 3 155.
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to
spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational after each engine
start as soon as control indicator b
extinguishes.
When TC 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.
Control indicator b 3 90.
Deactivation
TC can be switched off when spinning of drive wheels is required:
press b briefly to deactivate TC, k
illuminates. Deactivation is displayed
as status message in the Driver
Information Centre.
TC is reactivated by pressing b
again.
TC is also reactivated the next time
the ignition is switched on.
Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning. ESC operates in
combination with the Traction Control system (TC) 3 155.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESC is operational after each engine
start as soon as the control indicator
b extinguishes.

156Driving and operatingWhen 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.
Control indicator b 3 90.
Deactivation
For a more sporty behaviour ESC and
TC can be deactivated separately:
● Press b briefly: only Traction
control system is inactive, ESC
remains active, k illuminates.
● Press and hold b for min. five
seconds: TC and ESC are
deactivated, k and n illuminate.
Additionally, the selected mode is
displayed as status message in the
Driver Information Centre.
If the vehicle comes into threshold
with deactivated ESP, the system will reactivate ESP for the time duration
of the threshold, when the brake
pedal is depressed once.
ESC is reactivated by pressing b
again. If the TC system was
previously disabled, both TC and
ESC are reactivated.
ESC is also reactivated the next time
the ignition is switched on.Deactivation, OPC version
For very high-performance driving
ESC and TC can be deactivated
separately. The following modes are
selectable:
● Press b briefly: only Traction
control system is inactive, ESC
remains active, k illuminates.
● Press b twice briefly within two
seconds: TC is inactive, ESC is
operable without engine power
reduction, k and n illuminate.
● Press and hold b for min. five
seconds: TC and ESC are
completely inactive, k and n
illuminate.

Driving and operating157Additionally, the selected mode is
displayed as status message in the
Driver Information Centre.
On OPC version TC and ESC remain
deactivated even if the vehicle comes into threshold with unstable
driveability.
ESC is reactivated by pressing b
again. If the TC system was
previously disabled, both TC and
ESC are reactivated.
ESC is also reactivated the next time
the ignition is switched on.
Interactive driving system Flex RideFlex 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: both SPORT
and TOUR are not pressed, no
LED illuminates.Deactivate SPORT mode and TOUR
mode by pressing the corresponding
button once more.
In each driving mode, Flex Ride
networks the following electronic systems:
● Continuous Damping Control
● Accelerator Pedal Control
● Steering Control
● Electronic Stability Control (ESC)
● Antilock brake system (ABS) with
cornering brake control (CBC)
● Automatic transmissionSPORT mode
The settings of the systems are
adapted to a sportier driving style.
TOUR mode
The settings of the systems are
adapted to a comfort driving style.
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

Driving and operating161Pressing L for activating speed
limiter or switching off the ignition also
switches off cruise control and
deletes the stored speed.
Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum speed.
The maximum speed can be set at a
speed above 25 km/h.
The driver can only accelerate up to
the preset speed. Deviations from the
limited speed may occur when driving
downhill.
The preset speed limit is displayed in
the top line of the Driver Information
Centre when the system is active.Activation
Press L. If cruise control or adaptive
cruise control has been activated
before, it is switched off when speed
limiter is activated and control
indicator m extinguishes.
Set speed limit
With speed limiter active, hold thumb
wheel turned to RES/+ or briefly turn
to RES/+ repeatedly until the desired
maximum speed is displayed in the
Driver Information Centre.
Alternatively accelerate to the desired speed and briefly turn thumb wheel to SET/- : the current speed is stored as
maximum speed. Speed limit is
displayed in the Driver Information
Centre.

162Driving and operating
Change speed limit
With speed limiter active, turn thumb
wheel to RES/+ to increase or SET/-
to decrease the desired maximum
speed.
Exceeding the speed limit
In the event of an emergency, it is
possible to exceed the speed limit by
depressing the accelerator pedal
firmly beyond the point of resistance.
The limited speed will flash in the
Driver Information Centre and
(depending on vehicle) additionally a
chime sounds during this period.
Release the accelerator pedal and the speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Deactivation Press y: speed limiter is deactivated
and the vehicle can be driven without speed limit.
The limited speed is stored and a corresponding message appears in
the Driver Information Centre.
Resume limit speed
Turn thumb wheel to RES/+. The
stored speed limit will be obtained.
Switching off
Press L, the speed limit indication in
the Driver Information Centre
extinguishes. The stored speed is
deleted.
By pressing m to activate cruise
control or adaptive cruise control or
by switching off the ignition, speed
limiter is also deactivated and the
stored speed is deleted.Adaptive cruise control
Adaptive cruise control is an
enhancement to traditional cruise control with the additional feature of
maintaining a certain distance behind the vehicle ahead.
Adaptive cruise control automatically
decelerates the vehicle when
approaching a slower moving vehicle. It then adjusts the vehicle speed to
follow the vehicle ahead at the
selected following distance. The
vehicle speed increases or decreases
to follow the vehicle in front, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store and maintain speeds over approx.
50 km/h and brakes automatically to follow a slower vehicle driving ahead
to a minimum speed of 30 km/h.

Driving and operating163Adaptive cruise control uses a radar
sensor to detect the vehicles ahead.
If no vehicle is detected in the driving
path, the adaptive cruise control will
behave like a traditional cruise
control.
For safety reasons, the system
cannot be activated before the brake
pedal has been depressed once
since switching on ignition. Activation
in first gear is not possible.
Adaptive cruise control is mainly
advised to be used on long straight
roads, e.g. highways or country roads with steady traffic. Do not use the
system if it is not advisable to
maintain a constant speed.
Control indicator A 3 93, m 3 92.9 Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver
stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the cancel
switch have priority over any
adaptive cruise control operation.
Switching on
Press C to switch on adaptive cruise
control. The control indicator m
illuminates white.
Activation by setting the speed
Adaptive cruise control can be
activated between 50 km/h and
180 km/h.
Accelerate to the desired speed and
turn thumb wheel to SET/-, the
current speed is stored and
maintained. Control indicator m
illuminates green.
The adaptive cruise control symbol,
the following distance setting and set
speed are indicated in the top line of
the Driver Information Centre.
The accelerator pedal can be
released. Adaptive cruise control
remains activated while gearshifting.
Overriding set speedIt is always possible to drive faster
than the selected set speed by
depressing the accelerator pedal.
When the accelerator pedal is
released, the vehicle returns to the
desired distance if a slower vehicle is
ahead. Otherwise it returns to the
stored speed.

166Driving and operating● There is no traffic and nothingdetected on the road sides forseveral minutes. In this case,
there are no radar echoes and
the sensor may report that it is
blocked.
● The collision imminent braking system is applying the brakes.
● The radar sensor is blocked by an ice or water film.
● A fault is detected in the radar, engine or brake system.
When adaptive cruise control is
deactivated automatically, the control indicator m illuminates white and a
warning symbol is displayed as a pop-
up in the Driver Information Centre.
The stored speed is maintained.
9 Warning
When adaptive cruise control is
deactivated, the driver must take
over full brake and engine control.
Switching off
Press C to switch off adaptive cruise
control. The control indicator m
extinguishes. The stored speed is
deleted.
Switching off the ignition also
switches off adaptive cruise control
and deletes the stored speed.
Driver's attention
● Use adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and need time to detect it
again.
● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control.
● Do not use adaptive cruise control during rain, snow or
heavy dirt, as the radar sensor
can be covered by a water film,
dust, ice or snow. This reduces or suppresses completely the
visibility. In case of sensor
blockage, clean the sensor
cover.
System limits ● The system's automatic brake force does not permit hard
braking and the braking level
may not be sufficient to avoid a
collision.

180Driving and operating
The instructions in the display show:● A hint when driving faster than 30 km/h.
● 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.
Changing the parking side
The system is configured to detect
parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
indicator to the driver side for the
duration of searching.
As soon as turn indicator is switched off, the system searches for parking
slots on the passenger side again.
Display priorities
After activating the advanced parking
assist, a message appears in the
Driver Information Centre. Advanced
parking assist indication in the Driver
Information Centre can be inhibited
by vehicle messages with a higher
priority. After approving the message
by pressing SET/CLR on the turn
signal lever, advanced parking assist
instructions appear again and the
parking manoeuvre can be continued.
Deactivation
The system is deactivated by: ● short press of D if advanced
parking assist and front-rear
parking assist are activated
● long press of D if advanced
parking assist is activated
● successfully ending parking manoeuvre
● driving faster than 30 km/h
● switching off the ignition
