Driving and operating187The vehicle must be parked on a level
surface.
The filler neck for AdBlue is located
behind the fuel filler flap, which is located at right rear side of the
vehicle.
The fuel filler flap can only be opened if the vehicle is unlocked.
1. Remove key from ignition switch.2. Close all doors to avoid ammonia fumes entering the interior of the
vehicle.
3. Release the fuel filler flap by pushing the flap 3 246.
4. Unscrew protective cap from the
filler neck.
5. Open AdBlue canister.
6. Mount one end of the hose on the
canister and screw the other end
on the filler neck.
7. Lift the canister until it is empty, or
until the flow from the canister has stopped. This can take up to
five minutes.
8. Place the canister on the ground to empty the hose, wait
15 seconds.
9. Unscrew the hose from the filler neck.
10. Mount the protective cap and turn
clockwise until it engages.
Note
Dispose of AdBlue canister
according to environmental
requirements. To reuse the hose
flush it with clear water after usage.Automatic transmission
The automatic transmission permits
automatic gear shifting (automatic
mode) or manual gear shifting
(manual mode).
Manual shifting is possible in manual
mode by tapping the selector lever to + or - or pulling the steering wheel
paddles.

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
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, 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.

Service and maintenance301Use of engine oils for all petrol
engines with only ACEA quality is
prohibited, since it can cause engine
damage under certain operating
conditions.
Select the appropriate engine oil based on its quality and on the
minimum ambient temperature
3 304.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information on the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 304.All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
cold regions with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional
coolant additives will be rejected.Washer fluid
Use only washer fluid approved for
the vehicle to prevent damage of
wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
Brake and clutch fluid Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified
interval.
AdBlue Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 185.

and privacy
Event data recorders
Electronic control units are installed in
your vehicle. Control units process
data which is received by vehicle
sensors, for example, or which they
generate themselves or exchange
amongst themselves. Some control
units are necessary for the safe
functioning of your vehicle, others
assist you while you drive (driver
assistance systems), while others
provide comfort or infotainment
functions.
The following contains general
information about data processing in
the vehicle. You will find additional
information as to which specific data
is uploaded, stored and passed on to third parties and for what purpose in
your vehicle under the key word Data Protection closely linked to the
references for the affected functional
characteristics in the relevant owner's manual or in the general terms of
sale. These are also available online.Operating data in the vehicle
Control units process data for
operation of the vehicle.
This data includes, e.g.: ● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate,
"seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient, not
stored for longer than an operational
cycle, and only processed on board
the vehicle itself. Control units often
include data storage (including the
vehicle key). This is used to allow
information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.
