instrument cluster.
Temporary 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 and return
to D, do one of the following:
● Press + paddle for 1 second.
● Move selector lever towards the left to manual mode and back toposition 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, 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 3 199.
● Special programmes automatically adapt the shiftingpoints when driving up inclines or down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission controlenables 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 even in manual 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.

206Driving and operatingOnce the system is activated,
adaptive cruise control decelerates or
brakes if it detects a vehicle ahead,
which is slower or closer than the
desired following distance.9 Warning
Accelerating by the driver
deactivates automatic braking by
the system. This is indicated as a
pop-up warning in the Driver
Information Centre or by the
adaptive cruise control symbol
turning blue.
Indication on Driver Assistance page
As long as the set speed is
overridden, the bars in front of the
vehicle symbol appear blue.
Increase or reduce speed The preset speed can be changed by
moving thumb wheel to RES/+ to
increase or SET/- to decrease the
speed. Move thumb wheel repeatedly to change speed in small steps, move

Resume stored speed
If the system is switched on but
inactive and a speed was stored
before, move thumb wheel to RES/+
at a speed above 5 km/h (with
automatic transmission) or above 30
km/h (with manual transmission) to
resume the stored speed.Full speed range adaptive cruise
control on vehicles with automatic transmission
Full speed range adaptive cruise control will maintain a following
distance behind a detected vehicle
and slow your vehicle to a stop behind
that vehicle.
When the vehicle ahead accelerates
after a brief stop, the adaptive cruise
control will drive off automatically
without driver action. If necessary,
press RES/+ or the accelerator pedal
to resume adaptive cruise control.
Pressing the accelerator pedal allows
more control over the acceleration
after driving off. Note that automatic
braking is disabled during usage of
the accelerator pedal.
If the stopped vehicle ahead stands
for a longer time and then begins to
move forward, the green illuminated
vehicle ahead control indicator A will
flash and a warning chime will sound
as a reminder to check traffic before
resuming.
210Driving and operatingThe adaptive cruise control symbol
C changes from green to white when
the system is deactivated but not
switched off.9 Warning
When adaptive cruise control is
deactivated, the driver must take
over full brake and engine control
immediately.
Switching off the system
Press v to switch off adaptive cruise
control. The control indicator C
extinguishes in the Driver Information Centre. 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 mountainroads, as it can lose the vehicle
ahead and needs 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 of the vehicle.
● 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 limits9 Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● Adaptive cruise control does ignore the oncoming traffic.
● Adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● Adaptive cruise control considers
stopped vehicles only at low
speed.
● Do not use adaptive cruise control when towing a trailer.
● Do not use adaptive cruise control on roads with an incline ofmore than 10%.
Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may
Driving and operating213Note
Speed limit signs which are
combined with add-on signs, e.g.
time, weather or vehicle type
limitations, are not considered by
this system.
Note
The driver stays fully responsible for
driving conform to speed limits and
has to supervise any automatic set
speed change performed by this
system.
Due to system limitations and
latencies, the set speed might be
changed after entering the road
section with the new speed limit.
Speed limit signs between 30 km/h
and 150 km/h are considered.
Switching on the system
The function can be activated or
deactivated in the vehicle settings
menu of the Driver Information Centre

control has be to switched on as
described above.Usage
Even if adaptive cruise control is
inactive, the set speed is updated
automatically at each new detected
speed limit as described in the next
section. Press RES+ to re-activate
adaptive cruise control, using the
memorised set speed.
Note
Adaptive cruise control has to be
initiated once by pressing SET- after
ignition or just adaptive cruise
control has been is switched on.
If adaptive cruise control is active, the detected speed limit will be displayed in the Driver Information Centre. The
driver can accept or decline the
detected new set speed while the
display message is shown.
Press SET- on the steering wheel to
accept the detected speed limit and
take over as new set speed.
Press RES+ to decline detected
speed limit and keep the current set
speed.
If no action is performed when the
message is displayed, the detected
speed limit is taken over as new setspeed automatically after 3 seconds.
The message disappears and is
followed by the offset message:
If a new set speed was defined, a confirmation message is displayed.
During this time, the offset from the
set speed can be adjusted.
Press SET- or RES+ to adjust the
offset.
If no action is performed while the
message is displayed, the last set
offset will be used and the message
disappears after 3 seconds.
The new set speed including offset is displayed in the Driver Information
Centre.
System limitations
Intelligent adaptive cruise control has
the same limitations as the traffic sign assistant 3 238.
Implicit speed limits may be
considered with a delay, e.g. city entry, city exit, or highway entry signs.
The system may ignore a particular
traffic sign or use a wrong speed limit.
