Driving and operating175Selector lever
Always move the selector lever in the
appropriate direction as far as it will
go. Upon release, it automatically
returns to the centre position.
Notice
Do not hold the selector lever in an
intermediate position. Not fully
engaging a gear may lead to
malfunction and an error message may be displayed in the Driver
Information Centre.
Return the selector lever to the
centre position. After a short while N
will be displayed in the Driver
Information Centre and the system
will operate normally again.N:neutral positionD/M:switch between automatic (D)
and manual (M) shift mode.
The transmission display
shows either D or M with the
selected gear<:upshifting in manual mode]:downshifting in manual modeR:reverse gear. Engage only
when vehicle is stationary
If selector lever is moved from R to the
left, D is directly engaged.
If selector lever is moved from D to +
or -, manual mode M is selected and
the transmission shifts.
Starting off Depress the brake pedal and move
the selector lever to D/M or R. If D is
selected, transmission is in automatic
mode and first gear is engaged. If R
is selected, reverse gear is engaged.
The vehicle starts to move when the
brake pedal is released.
To start-off without depressing the
brake pedal, accelerate immediately
after engaging a gear as long as D or
R flashes.
If neither the accelerator nor the
brake pedal are depressed, no gear
is engaged and D or R flashes for a
brief time in the display.
Stopping the vehicle In D, first gear is engaged and the
clutch is released when the vehicle is
stopped. In R, reverse gear remains
engaged.
Engine braking
Automatic mode
When driving downhill, the manual
transmission automated does not shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
176Driving and operatingManual mode
To utilise the engine braking effect,
select a lower gear in good time when
driving downhill. Changing into
manual mode is only possible while
the engine is running or during an
Autostop.
Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between R and D in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
The most recently engaged gear (see transmission display) remains
engaged when switching off ignition.
With N, no gear is engaged.
Therefore always apply the parking
brake when switching off ignition. If
parking brake is not applied, P flashes
in the transmission display and the
key cannot be removed from the
ignition switch. P stops flashing in the
transmission display as soon as the
parking brake is slightly applied.When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
Emergency operation to avoid
freezing of the parking brake 3 164.
Manual mode
If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, the
shift is not executed. This prevents
the engine from running at too low or too high an engine speed. A warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 122.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.
Gear shift indication
The symbol R or S with a number
beside 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 adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or
gradients.
Kickdown
If the accelerator pedal is pressed down completely in automatic mode,
the transmission shifts to a lower gear
depending on engine speed.
Fault
To prevent damage to the manual transmission automated, the clutch is engaged automatically at high clutch
temperatures.
Driving and operating1793 109. The electric parking brake
operates automatically with
adequate force.
Before leaving the vehicle, check
the electric parking brake status.
Control indicator m 3 109.
The electric parking brake can always
be activated, even if the ignition is off.
Do not operate electric parking brake
system too often without engine
running as this will discharge the
vehicle battery.
Releasing
Switch on ignition. Keep foot brake
pedal depressed and then push
switch m.
Drive away function
Vehicles with manual transmission:
Depressing the clutch pedal and then slightly releasing the clutch pedal and
slightly depressing the accelerator
pedal releases the electric parking
brake automatically. This is not
possible when switch m is pulled at
the same time.
Vehicles with automatic transmission
or manual transmission automated:
Engaging D and then depressing the
accelerator pedal releases the
electric parking brake automatically.
This is not possible when switch m is
pulled at the same time.
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, the electric
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Automatic applying
If the vehicle is equipped with
automatic transmission and adaptive cruise control is active, electric
parking brake is applied automatically when vehicle is stopped by the
system for more than two minutes.
Parking brake releases automatically
after moving off.Functionality check
When the vehicle is not moving, the
electric parking brake might be
applied automatically. This is done to
check the system.
Fault
Failure mode of electric parking brake
is indicated by a control indicator j
and by a vehicle message which is
displayed in the Driver Information
Centre. Vehicle messages 3 122.
Apply electric parking brake: pull and
hold the switch m for more than
five seconds. If control indicator m
illuminates, electric parking brake is
applied.
Release electric parking brake: push
and hold the switch m for more than
two seconds. If control indicator m
extinguishes, electric parking brake is released.
Control indicator m flashes: electric
parking brake is not fully applied or released. When continuously
flashing, release electric parking
brake and retry applying.
Driving and operating187Adaptive 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 willnot exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store
and maintain speeds over approx.
15 mph. On vehicles with automatic
transmission, there is no lower speed limit and the system can also brake to
a stop.
Adaptive cruise control uses radar
and camera sensors to detect the
vehicles ahead. If no vehicle is
detected in the driving path, the
adaptive cruise control will behave
like a conventional cruise control.
For additional information including a
video, visit us online.
Adaptive cruise control is mainly
advised to be used on long straight
roads like 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 3 113, m 3 113,
C 3 113.9 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 the system
Press v to switch on adaptive cruise
control. C appears in the Driver
Information Centre.
Activation of the funtionality
Adaptive cruise control can be
activated at speeds above 15 mph on vehicles with automatic transmission
or 19 mph on vehicles with manual
transmission. The upper speed limit is
112 mph.
Accelerate to the desired speed and
turn thumb wheel to SET/-, the
current speed is stored and
maintained.
188Driving and operating
The adaptive cruise control symbol
C , the following distance setting and
set speed are indicated in the Driver
Information Centre.
The accelerator pedal can be
released. Adaptive cruise control
remains activated during gear
shifting.
Overriding set speed
It 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.
Once 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.
Take over current speed
If the accelerator pedal is pressed,
the current vehicle speed is taken
over as stored speed. This is also
valid, if the current vehicle speed is
lower than the Set Speed.
Increase speed
With adaptive cruise control active,
hold RES/+ to increase speed
continuously. Push RES/+ repeatedly
to increase speed in small
increments.
Reduce speed
With adaptive cruise control active,
hold SET/- to decrease speed
continuously. Push SET/- repeatedly
to decrease speed in small
increments.
Resume stored speed
If the system is switched on but
inactive and a speed was stored
before, turn thumb wheel to RES/+ at
a speed above 3 mph (with automatic transmission) or above 19 mph (withmanual 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,
190Driving and operating9Warning
The Driver accepts full
responsibility to drive with the
appropriate following distance
based on traffic, weather, visibility and regional regulation. Followingdistance must be adjusted or the
system switched off when required by the prevailing conditions.
Detecting the vehicle ahead
The green illuminated vehicle ahead
control indicator A is displayed when
the system detects a vehicle in the driving path. The range of the sensors
is between 25 and 150 metres
depending on vehicle speed.
Forward collision alert 3 194.
If this symbol does not display, or
displays briefly, adaptive cruise
control will not respond to vehicles ahead.
Deactivation of the functionality
Adaptive cruise control is deactivated by the driver when:
● y is pressed.
● Brake pedal is applied.
● Clutch pedal is depressed for more than four seconds.
● Selector lever of automatic transmission is moved to N.
The system is also automatically
deactivated when:
● Vehicle speed accelerates above
120 mph or slows down below
15 mph. Vehicles with automatic
transmission slows down to a stop without deactivating within
five minutes.
● The Traction Control system is deactivated or operating.
● The Electronic Stability Control is
deactivated or operating.● There is no traffic and nothing detected on the road sides for
approx. one minute. In this case
there are no radar echoes and
the sensor may report that it is
blocked.
● The active emergency braking system is applying the brakes.
● Driving on steep inclines.
● The radar sensor is blocked by an ice or water film.
● A fault is detected in the radar, camera, engine or brake system.
● The brakes need to cool down.
Additionally, the system is
automatically deactivated on vehicles with automatic transmission (full
speed range adaptive cruise control)
when:
● The incline uphill or downhill is greater than 20%.
● The electric parking brake is applied.
