activate, DISTRONIC PLUS if:
R ther oads are slippery, snow-covered or icy.

Otherwise, you may fail to recognise dangers
in time, cause an acciden tand injure yourself
and others.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 304).
If you want Distronic Plus to assist you, the
radar sensor system must be activated and
operational.
If no car is driving in front of you, Distronic

Do not use Distronic Plus while driving on
roads with steep gradients. G
Risk of accident
DISTRONIC PLUS brakes your vehicle at a
maximum of 4m/s2
depending on its speed.
This correspond stoapproximately 40 %of
your vehicle's maximum brak eforce. You must also apply th

Pulling away
X
If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you 0088.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
Driving
If there is no vehicle in front,D istronic Plus
operates in the same way as cruise control.
If as lower-moving vehicle is detected in front,
Distronic Plus causes your vehicle to brake
and maintain apreset distance to the vehicle
in front.
If Distronic Plus detectsaf aster-moving vehi-
cle in front,iti ncreases the driving speed, but
only up to the stored speed. G
Risk of accident
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
DISTRONIC PLUS then no longer brakes your
vehicle. The driver is fully responsible for the
vehicle's distance from other vehicles, its
speed and for braking in good time.
Stopping G
Risk of accident
The DISTRONIC PLUS braking effect is can-
celled and the vehicle can start moving if:
R DISTRONIC PLUS is deactivated using the
cruise control lever.
R you accelerate.
R the system or the power supply is disrup-
ted, e.g. due to battery failure.
R the electrical system in the engine com-
partment or the fuses are tampered with.
R the battery is disconnected. G
Risk of accident
Never get out of the vehicle when DISTRONIC
PLUS is activated.
DISTRONIC PLUS must never be operated or
deactivated by apassenger or from outside
the vehicle.
DISTRONIC PLUS does not replace the park-
ing brake and must not be used for parking.
If you wish to leave the vehicle or park it,
deactivate DISTRONIC PLUS and secure the
vehicle against rolling away.
If Distronic Plus detectst hat the vehicle in
front is stopping, it brakes your vehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to astandstill
at as ufficient distance behind the vehicle
in front.T he specified minimum distance is
set using the thumbwheel on the cruise-
control lever.
When Distronic Plus is activated and the vehi-
cle is at astandstill, awarning message
appears in the multi-function display if:
R the driver's door is opened and you release
the seat belt.
R the engine is switched off.
R the bonnet is opened.

Indicator lamp
0047 To deactivate/activate PARKTRONIC
If indicator lamp 0046lights up, PARKTRONIC is
deactivated. Parking Guidance is also deacti-
vated.
i PARKTRONIC is automaticallya ctivated
when you turn the key to position 2in the
ignition lock.
Trailer towing* PARKTRONIC is deactivated for the rear area
when you establish an electrical connection
between your vehicle and atrailer.
! Fold in the ball coupling if the trailer tow
hitch is not required.P ARKTRONIC meas-
ures the minimum detection range to an
obstacle from the bumper, not the ball cou-
pling. Parking Guidance*
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to meas-
ure the road on both sides of the vehicle. A
suitablep arking space is indicated by the
parking symbol. You receive steering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 138). G
Risk of accident
Parking Guidance is merely an aid and may
recommend parking spaces that are not suit-
able for parking. For example, these might be
spaces where parking is prohibited, drive-
ways, unsuitables urfaces, etc.
Parking Guidance measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Parking Guidance does not relieve you of the
responsibility for paying attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourselfa nd others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. G
Risk of accident
Objects located above the height range of
Parking Guidance will not be detected when
the parking space is measured. These are not
taken into account when the parking proce-
dure is calculated, e.g. overhanging loads, tail
sections or loading ramps of goods vehicles.
In some circumstances, Parking Guidance
might therefore issue steering instructions
too soon. This may lead to acollision. For this
reason, you should avoid using Parking Guid-
ance in such situations. 140
