Driving and operating187Indication on Driver Assistance page
If the system is switched on but
inactive, a white bar in the set gap
position appears in front of the vehicle symbol.
Activation of the functionality by
setting the speed
Adaptive cruise control can be
activated at speeds above 25 km/h on
vehicles with automatic transmission
or 30 km/h on vehicles with manual
transmission. The upper speed limit is 180 km/h.
Accelerate to the desired speed and
move thumb wheel to SET/-, the
current speed is stored and
maintained.
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.
Indication on Driver Assistance page

188Driving and operatingAs 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
and hold to change speed in large
steps.
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 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 cruisecontrol 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 was
stopped 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 proceeding.9 Warning
When full speed range adaptive
cruise control is deactivated or
cancelled, the vehicle will no
longer be held at a stop and can
start moving. Always be prepared
to manually apply the brake pedal
to hold the vehicle stationary.
Do not leave the vehicle while it is being held at a stop by the full
speed range adaptive cruise
control. Always move selector
lever to park position P and switch
off the ignition before leaving the
vehicle.
Setting the following distance
When adaptive cruise control detects a slower moving vehicle in the drivingpath, it will adjust the vehicle speed to
maintain the following distance
selected by the driver.
The following distance can be set to
near, medium or far.

Fault
In the event of a fault or if the system
does not work temporarily, e.g.
because of high external noise level
or other interference factors, a
message pops-up in the Driver
Information Centre.
Vehicle messages 3 123.Advanced parking assist9 Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
the advanced parking assist.
The advanced parking assist
measures a suitable parking slot
while passing, calculates the
trajectory and automatically steers
the vehicle into a parallel or
perpendicular parking slot.
Instructions are given in the Driver
Information Centre 3 112 or,
depending on the version, on the Info Display 3 118 , supported by acoustic
signals.
The driver must control acceleration,
braking and gear shifting, while
steering is done automatically.
Page 211 of 323

Driving and operating209Indication in the Info Display
Select parallel or perpendicular
parking slot by tapping the respective icon on the display.
Select parking side by tapping the
respective icon on the display.
When a slot is detected, a visual
feedback on the Info Display and an
acoustic signal is given.
If the driver does not stop the vehicle after a parking slot is proposed, the
system starts to search for another
suitable parking slot.
Park guiding mode
The parking slot suggestion of the system is accepted when the vehicle
is stopped by the driver within ten
metres for parallel parking slots or
six metres for perpendicular parking
slots after the message to stop the car
is indicated. The system calculates
the optimal path into the parking slot.A brief vibration in the steering wheel
after engaging reverse gear indicates
that the steering is controlled by the
system. Then the vehicle with manual transmission is steered into the slot
automatically by giving the driver
detailed instructions for braking,
accelerating and gear shifting. With
automatic transmission the vehicle is
steered into the slot automatically by
giving the driver detailed instructions for accelerating and shifting forward
or reversing. The driver must keep
hands away from the steering wheel.
During park guiding mode the
manoeuvring speed is limited.
Always pay attention to the signals of
the front-rear parking assist.
Continuous signal indicates that the
distance to an obstacle is less than approx. 30 cm.
If, for any reason, the driver must take over control of the steering, hold the
steering wheel only at the outer edge. Automatic steering is cancelled in thisevent.

Vehicle care277Towing
Towing the vehicle
Wrap a cloth around the tip of a flat
screwdriver to prevent paint damage.
Insert the screwdriver in the slot at the
edge of the cap. Release the cap by
levering it out carefully.
The towing eye is stowed with the
vehicle tools 3 259.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for
towing and not for recovering the
vehicle.
Switch on ignition to release steering wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 200, otherwise the
vehicle may automatically brake during towing.
Switch the selector lever to neutral.
Release the parking brake.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
